The Nervous System: Foundation of Human Perception and Action

The human nervous system is a complex network of structures that play a crucial role in transmitting information about external and internal stimuli, as well as coordinating our behaviors. It consists of two main parts: the central nervous system and the peripheral nervous system.

Central Nervous System (CNS)

The central nervous system comprises the brain and spinal cord. Its primary functions include:

• Organizing and interpreting information received from the peripheral nervous system
• Initiating responses to stimuli
• Controlling higher-order cognitive functions

Peripheral Nervous System (PNS)

The peripheral nervous system is further divided into two subsystems:

1. Somatic Nervous System: Responds to sensory information from outside the body and controls voluntary movements of skeletal muscles
2. Autonomic Nervous System: Governs involuntary activities of smooth muscles and glands involved in circulation, respiration, and digestion

The autonomic nervous system is further subdivided into the sympathetic division (responsible for “fight or flight” responses) and the parasympathetic division (which calms the body after stress or danger).

Neurons: The Building Blocks of the Nervous System

Neurons are specialized cells that form the foundation of the nervous system. They are responsible for transmitting information electrically and chemically throughout the body. How many types of neurons exist in the human nervous system?

There are three main types of neurons:

1. Sensory neurons: Respond to external and internal stimuli
2. Motor neurons: Carry information to parts of the body capable of responding
3. Interneurons: Connect neurons to each other

The human brain contains approximately 100 billion neurons, showcasing the complexity of our nervous system.

Anatomy of a Neuron

A typical neuron consists of several key components:

• Dendrites: Small branches that connect to nearby neurons
• Axon: A single, long extension that can reach up to a meter in length, connecting to dendrites of distant neurons
• Cell body: Contains the nucleus and other essential cellular components
• Synapses: Small spaces between neurons where chemical communication occurs

Neural Transmission

Neurons transmit information through a combination of electrical and chemical signals. The electrical component, known as an action potential, follows an “all-or-none” principle. This means that a neuron either fires completely or not at all. The intensity of stimulation affects the frequency of firing rather than the likelihood of a response.

At synapses, neurons communicate through the release of chemical messengers called neurotransmitters. These molecules can either excite or inhibit the receiving neuron, depending on the type of receptor activated.

Neurotransmitters: Chemical Messengers of the Nervous System

Neurotransmitters play a crucial role in neural communication and can significantly impact mood, thought, and behavior. What are some of the major neurotransmitters and their functions in the body?

• Acetylcholine: Involved in muscle contraction, attention, and memory
• Dopamine: Associated with reward, motivation, and motor control
• Serotonin: Regulates mood, sleep, and appetite
• Norepinephrine: Involved in arousal, attention, and stress responses
• GABA (Gamma-aminobutyric acid): The main inhibitory neurotransmitter in the brain
• Glutamate: The primary excitatory neurotransmitter in the brain

Understanding the roles of these neurotransmitters is crucial for developing treatments for various neurological and psychiatric disorders.

The Human Brain: Evolution’s Masterpiece

The human brain is often considered the pinnacle of evolutionary achievement, enabling our most complex behaviors, thoughts, and emotions. How does the human brain compare to that of other mammals?

While similar in construction to other mammalian brains, the human brain is significantly larger in proportion to our body size. This increased brain size is a key factor in our ability to develop language, create tools, and engage in complex problem-solving.

Brain Research Initiatives

Recognizing the importance of understanding the brain, several major research initiatives have been launched:

• The “Decade of the Brain” (1990s): A United States government initiative that led to significant progress in brain research
• The BRAIN Initiative (2013): Launched by President Barack Obama to advance innovative neurotechnologies and deepen our understanding of brain function

These initiatives have paved the way for groundbreaking discoveries in neuroscience and continue to drive progress in the field.

The Endocrine System: Hormonal Regulation of Bodily Functions

While the nervous system provides rapid, short-term control of bodily functions, the endocrine system offers a complementary system of regulation through hormones. How does the endocrine system differ from the nervous system in its method of communication?

The endocrine system uses chemical messengers called hormones, which are released into the bloodstream and travel throughout the body to target specific cells or organs. This method of communication is generally slower but can have longer-lasting effects compared to neural transmission.

Major Components of the Endocrine System

The endocrine system consists of several glands and organs that produce and secrete hormones:

• Pituitary gland: Often called the “master gland” as it controls many other endocrine glands
• Thyroid gland: Regulates metabolism and growth
• Parathyroid glands: Control calcium levels in the blood and bones
• Adrenal glands: Produce stress hormones and regulate metabolism
• Pancreas: Secretes insulin and glucagon to regulate blood sugar levels
• Gonads (ovaries in females, testes in males): Produce sex hormones
• Pineal gland: Regulates sleep-wake cycles
• Hypothalamus: Links the nervous system to the endocrine system

Hormones: Chemical Messengers of the Endocrine System

Hormones are specialized molecules that act as the endocrine system’s messengers, traveling through the bloodstream to target specific cells or organs. How do hormones affect various bodily functions?

Hormones influence a wide range of physiological processes, including:

• Metabolism
• Growth and development
• Reproduction
• Mood and behavior
• Stress responses
• Blood sugar regulation
• Calcium homeostasis
• Sleep-wake cycles

The effects of hormones can be both short-term and long-term, allowing for precise regulation of bodily functions over varying time scales.

Types of Hormones

Hormones can be classified into three main categories based on their chemical structure:

1. Steroid hormones: Derived from cholesterol (e.g., cortisol, testosterone, estrogen)
2. Peptide hormones: Chains of amino acids (e.g., insulin, growth hormone)
3. Amine hormones: Derived from amino acids (e.g., thyroid hormones, epinephrine)

Each type of hormone has unique properties that influence its production, transport, and mechanism of action within the body.

The Endocrine System and Homeostasis

One of the primary functions of the endocrine system is to maintain homeostasis, the body’s ability to maintain a stable internal environment despite changes in external conditions. How does the endocrine system contribute to homeostasis?

The endocrine system helps maintain homeostasis through several mechanisms:

• Negative feedback loops: Most hormones are regulated through negative feedback, where the presence of the hormone inhibits its further production
• Positive feedback loops: In some cases, hormones can stimulate their own production, leading to rapid increases in hormone levels
• Integration with the nervous system: The endocrine and nervous systems work together to respond to both internal and external stimuli
• Long-term regulation: Hormones can have lasting effects on gene expression and cellular function, allowing for adaptive responses to chronic changes in the environment

By constantly monitoring and adjusting hormone levels, the endocrine system helps maintain a balanced internal state across various physiological parameters.

Examples of Endocrine-Mediated Homeostasis

Several key homeostatic processes are regulated by the endocrine system:

1. Blood glucose regulation: Insulin and glucagon work together to maintain stable blood sugar levels
2. Calcium homeostasis: Parathyroid hormone and calcitonin regulate calcium levels in the blood and bones
3. Fluid and electrolyte balance: Antidiuretic hormone and aldosterone help maintain proper hydration and electrolyte levels
4. Body temperature regulation: Thyroid hormones play a role in regulating metabolic rate and heat production
5. Stress response: Cortisol and other stress hormones help the body adapt to challenging situations

Endocrine Disorders: When Hormonal Balance Is Disrupted

Endocrine disorders occur when there is an imbalance in hormone production or function. How do endocrine disorders impact overall health?

Endocrine disorders can have wide-ranging effects on the body due to the diverse roles that hormones play in regulating physiological processes. Some common endocrine disorders include:

• Diabetes mellitus: Characterized by impaired insulin production or function, leading to elevated blood sugar levels
• Thyroid disorders: Conditions such as hypothyroidism or hyperthyroidism can affect metabolism, energy levels, and overall health
• Adrenal insufficiency: Inadequate production of adrenal hormones can lead to fatigue, weight loss, and electrolyte imbalances
• Growth hormone deficiency: Can result in stunted growth in children and various metabolic issues in adults
• Polycystic ovary syndrome (PCOS): A common endocrine disorder in women that can affect fertility, metabolism, and appearance

Endocrine disorders can significantly impact quality of life and may require long-term management through medication, lifestyle changes, or other interventions.

Diagnosis and Treatment of Endocrine Disorders

Diagnosing and treating endocrine disorders often involves a multidisciplinary approach:

1. Blood tests: Measuring hormone levels in the blood can help identify imbalances
2. Imaging studies: Techniques such as ultrasound, CT, or MRI can visualize endocrine glands and detect abnormalities
3. Genetic testing: Some endocrine disorders have a genetic component that can be identified through DNA analysis
4. Hormone replacement therapy: Many endocrine disorders are treated by supplementing or replacing the deficient hormone
5. Lifestyle modifications: Diet, exercise, and stress management can play important roles in managing endocrine disorders
6. Surgery: In some cases, surgical intervention may be necessary to remove tumors or dysfunctional glands

Advances in endocrinology continue to improve our ability to diagnose and treat hormonal imbalances, leading to better outcomes for patients with endocrine disorders.

The Nervous and Endocrine Systems – Psychology

Chapter 2: Biology and Human Potential

The Nervous System: Connecting Sensation and Movement

As we consider the human genotype, we will start by providing an overview of the (see Figure 2.7), those structures which transmit information regarding external and internal stimulation and coordinate behavior.

Figure 2.7  Overview of human nervous system

The , consisting of the brain and spinal cord, organizes and interprets information received from the peripheral nervous system and initiates responding. The responds to sensory information originating outside the body and stimulates the skin, joints, and skeletal muscles. This type of behavior is often considered voluntary. The governs the activity of the smooth muscles and glands internal to the body involved in circulation, respiration, and digestion (see Figure 2.8). This type of activity is often considered involuntary. The division results in arousal under stressful or dangerous conditions as the body is prepared for “fight or flight.” The division calms the body upon removal of the stress or danger.

Figure 2.8  The autonomic nervous system

Making the Physical Connections: The Neuron

Even very simple animals require some way of connecting environmental input with behavioral output. Specialized nerve cells called are required to respond to external and internal stimulation (i.e., sensory neurons) and carry information to parts of the body capable of responding (i.e., motor neurons). A third type of cell referred to as an connects nerve cells to each other. Nervous systems consist of these types of specialized neurons and range in size from a few hundred nerve cells in worms to approximately 100 billion nerve cells in humans. Neurons are capable of transmitting information electrically and chemically. Figure 2.9 portrays the major parts of a neuron. are small branches which can connect to nearby neurons. A single can extend in length up to about a meter in humans and connect to the dendrites of more distant neurons. For example, a neuron could connect the spinal cord to a foot.

Figure 2.9  The neuron

Nerve cells “fire” (i.e., achieve their electrical ) according to an . That is, either the cell is totally activated or not at all. Increasing the intensity of stimulation does not increase the likelihood of a nerve responding. Rather, it increases the nerve’s rate of firing (i.e., frequency over time). For example, as a lamp becomes brighter, this does not increase the likelihood of a receptor cell in your eye firing. Rather, it increases the frequency with which the receptor cell fires. Nerves can fire at rates as high as a thousand times per second.

Making Chemical Connections: Neurotransmitters

The chemical exchange between neurons occurs at , the small spaces separating the dendrites and axon endings (see Figure 2.10).

Figure 2.10  The synapse

The first nerve cell releases chemical that can bind with receptors in the second neuron. The exchange can result in or , depending upon the type of receptor activated. Figure 2.11 lists the major neurotransmitters along with their roles in the body.

Figure 2.11  The major neurotransmitters

can affect mood, thought, and behavior. Most achieve these effects by impacting upon neurotransmitters and synaptic connections. In Chapter 11 (Maladaptive Behavior), we will consider the use of psychoactive drugs in the treatment of depression and schizophrenia.

The Brain

For literal and figurative reasons, it is tempting to refer to the human brain as evolution’s crowning achievement. After all, the brain sits atop our nervous system and enables our most complex overt and covert behaviors. Your thoughts, your feelings, all the complex things you do, would not be possible without this organ housed inside your skull on top of your head.

The human brain is similar in construction to the brains of other mammals but much larger in comparison to the size of our bodies. Without the increase in brain size occurring during human evolution it would not matter if we inherited the physical structures necessary to speak and create tools. This potential would never be realized. Manhattan would still look the same as it did 400 years ago. We are now using our remarkable brain to study itself. The United States government declared the 1990s as the “Decade of the Brain” and much progress has been made in understanding how the brain operates. President Barack Obama of the United States declared “The BRAIN (Brain Research through Advancing Innovative Neurotechnologies) Initiative” in 2013, hoping to advance this knowledge.

There are many ways of describing the brain in terms of its structure (i.e., anatomy) or function (i.e., parts operating together in producing a specific effect). Figure 2.12 shows the major parts of the human brain.  The is involved in the higher human cognitive functions including attention, perception, thinking, memory, language and consciousness.

Figure 2.12  Human brain

The brain is an adaptive organ connecting sensation with movement. Besides the primary somatosensory area in the , sensory areas include the for vision and for hearing. Besides the primary motor area at the rear of the , motor areas include the brain stem and spinal cord. The rest of the cortex is referred to as association areas and is dedicated to perception and cognition. It is the size and structure of this area which expanded enormously as humans evolved and enabled us to not only survive but to transform the human condition.

A human brain weighs about three pounds and feels “squishy” (something like gelatin). The cerebral cortex covers most of the brain and is comprised of nerve fibers folded in such a manner (called ) to increase the amount of surface area in the total space. There are two symmetrical halves often referred to as the left brain (or hemisphere) and right brain (or hemisphere). The two halves are connected by the , a thick network of nerve fibers enabling the two sides to communicate. The left side of the brain connects to the right side of the body and vice versa. Certain activities appear more characteristic of one side than the other (see Figure 2.13). These distinctions are referred to as . Despite the different emphases, both sides usually act in concert in carrying out these activities (Toga & Thompson, 2003).

Figure 2.13  Brain lateralization

Most of the expansion in the size of the human brain occurred in the frontal lobe. This part of the brain is involved in self-control, described in Chapter 1, and in abstract thought and problem-solving, described in Chapter 7. The small occipital lobe is dedicated to vision, described in Chapter 3. At the borders of the frontal and parietal lobes is a deep fissure (the ) where large strips of neural tissue dedicated to sensation (the primary somatosensory cortex) and movement (the primary motor cortex) meet. The temporal lobe is primarily involved with memory and language, described in Chapter 6. The parietal lobe is involved with sensation originating in the skin, muscles, and joints.

The Endocrine System: Hormonal Regulation

The consists of ductless glands that secrete s (chemical messengers) into the blood stream to maintain homeostasis. It exists in all animals having a nervous system. Like the nervous system, the endocrine system enables communication between different parts of the body.

The endocrine system maintains homeostasis through a series of feedback loops, the most important of which are controlled by the interacting with the. Often, the hypothalamus stimulates the pituitary gland to secrete an activating hormone to another gland. If a signal is transmitted to a gland, indicating low blood levels of its hormone, it secretes additional amounts into the blood stream. Once the optimal level is restored, the gland stops secreting the hormone. In this way the endocrine system plays its critical role in metabolism, growth, sexual development, reproduction, and responding to stress. Figure 2.14 shows the locations of the major glands.

Figure 2.14 Major gland locations

The connects to the base of the hypothalamus and is often referred to as the master gland since it secretes several different hormones impacting upon other glands involved in maintaining homeostasis. Hormones secreted by the pituitary control growth, blood pressure, water balance, temperature regulation, and pain relief. The is located at the base of the cortex between the two hemispheres and next to the thalamus. It influences the sleep-wake cycle by secreting the hormone melatonin when stimulated by light. The is located in the neck by the larynx (voice box) and affects metabolism by controlling the rate at which energy is expended. It is one of the glands under the control of the pituitary which secretes thyroid-stimulating hormone (TSH). The pituitary in turn is controlled by the hypothalamus through the release of thyrotropin-releasing hormone (TRH). Humans usually have four located on the rear surface of the thyroid gland. These control the amount of calcium in the blood and bones. The is located below the thyroid gland in the middle of the chest. It is an important part of the immune system. Damage, such as through contracting the HIV virus, can result in increased susceptibility to infection (e.g., AIDS). The lies toward the bottom of your rib cage and is involved in the removal of red blood cells. The are located on top of the kidneys and through the release of epinephrine (adrenalin) are significantly involved in the body’s “fight-or-flight” response in reaction to danger. The (ovaries for the female and testes for the male) secrete hormones controlling the development of the reproductive sex organs and secondary sex characteristics (e.g., pubic hair) during puberty.

Unlike plant hormones, animal hormones are often (though not always) produced in specialized hormone-synthesizing glands (shown below). The hormones are then secreted from the glands into the blood stream, where they are transported throughout the body. There are many glands and hormones in different animal species, and we will focus on just a small collection of them.

Locations of endocrine glands in the human body. Image credit: OpenStax Anatomy and Physiology.

In vertebrates, glands and hormones they produce include (note that the following list is not complete):

• hypothalamus: integrates the endocrine and nervous systems; receives input from the body and other brain areas and initiates endocrine responses to environmental changes; synthesizes hormones which are stored in the posterior pituitary gland; also synthesizes and secretes regulatory hormones that control the endocrine cells in the anterior pituitary gland. Hormones produced include
  • growth-hormone releasing hormone: stimulates release of growth hormone (GH) from the anterior pituitary
  • corticotropin-releasing hormone: stimulates release of adrenocorticotropic hormone (ACTH) from the anterior pituitary
  • thyrotropin-releasing hormone: stimulates release of thyroid-stimulating hormone (TSH) from the anterior pituitary
  • gonadotropin-releasing hormone: stimulates release of follicle -stimulating hormone and luteinizing hormone from the anterior pituitary
  • antidiuretic hormone (vasopressin): promotes reabsorption of water by kidneys; stored in posterior pituitary
  • oxytocin: induces uterine contractions labor and milk release from mammary glands; stored in posterior pituitary
• pituitary gland: the body’s master gland; located at the base of the brain and attached to the hypothalamus via a stalk called the pituitary stalk; has two distinct regions: the anterior portion of the pituitary gland is regulated by releasing or release-inhibiting hormones produced by the hypothalamus, and the posterior pituitary receives signals via neurosecretory cells to release hormones produced by the hypothalamus. Hormones produced (or secreted) by the gland include:
  • anterior pituitary: the following hormones are produced by the anterior pituitary and released in response to hormone signals from the hypothalamus
    • growth hormone: stimulates growth factors
    • adrenocorticotropic hormone (ACTH): simulates adrenal glands to secrete glucocorticoids such as cortisol
    • thyroid-stimulating hormone: stimulates thyroid gland to secrete thyroid hormones
    • follicle-stimulating hormone (FSH) and luteinizing hormone (LH): stimulates production of gametes and sex steroid hormones
    • prolactin: stimulates mammary gland growth and milk production
  • posterior pituitary: the following hormones are produced by the hypothalamus and stored in the posterior pituitary
    • antidiuretic hormone: promotes reabsorption of water by kidneys; stored in posterior pituitary
    • oxytocin: induces uterine contractions during labor and milk release from mammary glands during suckling; stored in posterior pituitary
• thyroid gland: butterfly-shaped gland located in the neck; regulated by the hypothalamus-pituitary axis; produces hormones involved in regulating metabolism and growth:
  • thyroxine (T₄) and triiodothyronine (T3): increase the basal metabolic rate, affect protein synthesis and other metabolic processes, help regulate long bone growth (synergy with growth hormone)
• adrenal glands: two glands, each located on one kidney; consist of adrenal cortex (outer layer) and adrenal medulla (inner layer), which each produce different sets of hormones:
  • adrenal cortex:
    • mineralocorticoids, such as aldosterone: increases reabsorption of sodium by kidneys to regulate water balance
    • glucocorticoids, such as cortisol and related hormones: long-term stress response hormones that increase blood glucose levels by stimulating synthesis of glucose and gluconeogenesis (converting a non-carbohydrate to glucose) by liver cells; promote the release of fatty acids from adipose tissue
  • adrenal medulla:
    • epinephrine (adrenaline) and norepinephrine (noradrenaline): short-term stress response (“fight-or-flight”) hormones that increase heart rate, breathing rate, cardiac muscle contractions, blood pressure, and blood glucose levels; accelerate the breakdown of glucose in skeletal muscles and stored fats in adipose tissue; release of epinephrine and norepinephrine is stimulated directly by neural impulses from the sympathetic nervous system
• pancreas: located between the stomach and the proximal portion of the small intestine; regulates blood glucose levels via the hormones:
  • insulin: decreases blood glucose levels by promoting uptake of glucose by liver and muscle cells and conversion to glycogen (a sugar storage molecule)
  • glucagon: increases blood glucose levels by promoting breakdown of glycogen and release of glucose from the liver and muscle
• gonads: produce sex steroid hormones that promote development of secondary sex characteristics and regulation of gonad function:
  • ovaries (in females):
    • estradiol: regulates development and maintenance of ovarian and menstrual cycles
    • progesterone: prepares uterus for pregnancy
  • testes (in males): regulates development and maintenance of sperm production

This video provides a nice overview of the glands and hormones of the vertebrate endocrine system:

The information below was adapted from OpenStax Biology 37.3

Hormones have a wide range of effects and modulate many different body processes. The key regulatory processes that will be examined here are those affecting blood glucose, hunger, metamorphosis, stress, and sex. We will primarily focus on these processes in vertebrates, but will also consider invertebrates in some cases.

Blood Glucose

Glucose is the primary energy source for most animal cells, and it is distributed throughout the body via the blood stream. The ideal, or target, blood glucose concentration is about 90 mg/100 mL of blood, which equates to about 1 tsp of glucose per 6 quarts of blood. After a meal, carbohydrates are broken down during digestion and absorbed into the blood stream. The amount present following a meal is typically more than what the body needs at that moment, and so the extra glucose must be removed and stored for later use. The opposite phenomenon occurs following a period of fasting. Insulin and glucagon are the two hormones primarily responsible for maintaining appropriate blood glucose levels.

Insulin is produced by the beta cells of the pancreas, which are stimulated to release insulin as blood glucose levels rise (for example, after a meal is consumed). Insulin lowers blood glucose levels through several processes:

• enhances the rate of glucose uptake and utilization by target cells, which use glucose for ATP production
• stimulates the liver to convert glucose to glycogen, which is then stored by cells for later use
• increases glucose transport into certain cells, such as muscle cells and the liver
• stimulates the conversion of glucose to fat in adipocytes and the synthesis of proteins.

These actions together cause cause blood glucose concentrations to fall, called a hypoglycemic ‘low sugar’ effect, which inhibits further insulin release from beta cells through a negative feedback loop.

When blood glucose levels decline below normal levels, for example between meals or when glucose is utilized rapidly during exercise, the hormone glucagon is released from the alpha cells of the pancreas. Glucagon raises blood glucose levels, eliciting what is called a hyperglycemic effect through several mechanisms:

• stimulates the breakdown and release of glucose from glycogen in liver cells
• stimulates absorption of amino acids from the blood by the liver, which then converts them to glucose
• stimulates adipose cells to release fatty acids into the blood

Glucose can then be utilized as energy by muscle cells and released into circulation by the liver cells. These actions mediated by glucagon result in an increase in blood glucose levels to normal homeostatic levels. Rising blood glucose levels inhibit further glucagon release by the pancreas via a negative feedback mechanism. In this way, insulin and glucagon work together to maintain homeostatic glucose levels, as shown in below.

Insulin and glucagon regulate blood glucose levels. When blood glucose levels fall, the pancreas secretes the hormone glucagon. Glucagon causes the liver to break down glycogen, releasing glucose into the blood. As a result, blood glucose levels rise. In response to high glucose levels, the pancreas releases insulin. In response to insulin, target cells take up glucose, and the liver converts glucose to glycogen. As a result, blood glucose levels fall. Image credit: OpenStax Biology

Uncontrolled blood glucose levels can lead to different types of serious medical conditions:

• Impaired insulin function can lead to a condition called diabetes mellitus. Diabetes mellitus can be caused by low levels of insulin production by the beta cells of the pancreas, or by reduced sensitivity of tissue cells to insulin. Either of these situations prevents glucose from being absorbed by cells, causing high levels of blood glucose, or hyperglycemia (high sugar). High blood glucose levels make it difficult for the kidneys to recover all the glucose from nascent urine, resulting in glucose being lost in urine. High glucose levels also result in less water being reabsorbed by the kidneys, causing high amounts of urine to be produced; this may result in dehydration. Over time, high blood glucose levels can cause nerve damage to the eyes and peripheral body tissues, as well as damage to the kidneys and cardiovascular system.
• Oversecretion of insulin can cause hypoglycemia, low blood glucose levels, which causes insufficient glucose availability to cells, often leading to muscle weakness, and can sometimes cause unconsciousness or death if left untreated.

This animation describes diabetes and the roles of insulin and the pancreas in blood glucose regulation:

Hunger Management

The immediate form of energy for most animal cells is glucose, and extra glucose is stored as glycogen which is readily broken down into glucose when needed. Longer term reserves of energy are stored as fats, in cells called adipocytes.  Too little fat means there may no be enough energy reserves in times when food is less available, and will cause an animal to feel hungry; however, too much fat is generally unhealthy and is likely to cause an animal to feel satisfied. The hormone leptin helps maintain an appropriate amount of fat reserves in the body.

Rather than being secreted from a specialized gland, leptin is produced by adipocytes in proportion to their number and size. More and larger adiopcytes means more leptin; fewer and smaller adipocytes means less leptin. Leptin levels are detected by sensors in the hypothalamus. High lepin levels suppress appetite and speed up metabolism, while low levels of leptin stimulate hunger and slow down metabolism, resulting in a negative feedback loop. These activities are mediated through signaling from the hypothalamus-pituitary axis to the thyroid, which plays a major role in regulating metabolic function.

In response to high levels of leptin, the hypothalamus releases thyrotropin-releasing hormone, signals to the anterior pituitary to release thyroid-stimulating hormone. The thyroid the releases thyroxine, also known as tetraiodothyronine or T₄, and triiodothyronine, also known as T₃. These hormones affect nearly every cell in the body except for the adult brain, uterus, testes, blood cells, and spleen. T₃ and T₄ activate genes involved in energy production and glucose oxidation, resulting in increased rates of metabolism and body heat production which together cause an increased rate of caloric usage. Low levels of leptin cause the opposite response, leading to a decreased metabolic rate to conserve energy.

This video describes how the thyroid manages metabolic processes:

Growth and Metamorphosis

In vertebrate species that undergo metamorphosis, such as amphibians, surges of T₃ are responsible for initiating development of new structures, reorganization of  internal organ systems, and other processes that occur during metamorphosis. In insects, metamorphosis is controlled by a set of hormones that determine whether the animal grows into the next larval stage or changes into an adult as it gets larger. The corpus allatum, an endocrine gland in the brain, secretes a hormone called juvenile hormone during all larval stages, which maintains the larval status of the animal. As the larvae grows, another endocrine gland in the brain releases prothoracicotropic hormone, which signals to the prothoracic gland to release the hormone ecdysone. Ecdysone promotes either molting (shedding the exoskeleton) or metamorphosis, depending on the level of juvenile hormone. Ecdysone in combination with high juvenile hormone results in molting into the next larval stage; ecdysone in combination with low juvenile hormone results in metamorphosis into an adult.

One of the main functions of endocrine hormones is to ensure the body’s internal environment remains stable (homeostasis). Stressors are stimuli that disrupt homeostasis. Some stressors require immediate attention and activate the short term, “fight-or-flight” stress response, which stimulates an increase in energy levels through increased blood glucose levels. This prepares the body for physical activity that may be required to respond to stress: to either fight for survival or to flee from danger. The fight-or-flight response exists in some form in all vertebrates.

In contrast, some stresses, such as illness or injury, can last for a long time. Glycogen reserves, which provide energy in the short-term response to stress, are exhausted after several hours and cannot meet long-term energy needs. If glycogen reserves were the only energy source available, neural functioning could not be maintained once the reserves became depleted due to the nervous system’s high requirement for glucose. In this situation, the body has evolved a response to counter long-term stress through the actions of the glucocorticoids, which ensure that long-term energy requirements can be met. The glucocorticoids mobilize lipid and protein reserves, stimulate gluconeogenesis, conserve glucose for use by neural tissue, and stimulate the conservation of salts and water.

The sympathetic nervous system regulates the stress response via the hypothalamus. Stressful stimuli cause the hypothalamus to signal the adrenal medulla (which mediates short-term stress responses) via nerve impulses, and the adrenal cortex, which mediates long-term stress responses, via the hormone adrenocorticotropic hormone (ACTH), which is produced by the anterior pituitary.

Short-term Stress Response

When presented with a stressful situation, the body responds by calling for the release of hormones that provide a burst of energy. The hormones epinephrine (also known as adrenaline) and norepinephrine (also known as noradrenaline) are released by the adrenal medulla. These two hormones prepare the body for a burst of energy in the following ways:

• cause glycogen to be broken down into glucose and released from liver and muscle cells
• increase blood pressure
• increase breathing rate
• increase metabolic rate
• change blood flow patterns, leading to increased blood flow to skeletal muscles, heart, and brain; and decreased blood flow to digestive system, skin, and kidneys

Watch this Discovery Channel animation describing the flight-or-flight response.

Long-term Stress Response

Long-term stress response differs substantially from short-term stress response. The body cannot sustain the bursts of energy mediated by epinephrine and norepinephrine for long times. Instead, other hormones come into play. In a long-term stress response, the hypothalamus triggers the release of ACTH from the anterior pituitary gland. The adrenal cortex is stimulated by ACTH to release steroid hormones called corticosteroids. The two main corticosteroids are glucocorticoids such as cortisol, and mineralocorticoids such as aldosterone. These hormones mediate the long-term stress response in the following ways:

• glucocorticoids:
  • promote breakdown of fat into fatty acids in the adipose tissue and release into bloodstream for ATP production
  • stimulate glucose synthesis from fats and proteins to increase blood glucose levels
  • inhibit immune function to conserve energy
• mineralcorticoids:

Glands and hormones of the animal body. — Veterinary Centers for Minimally Traumatic Surgery and Comprehensive Recovery Lebedi

All tissues of the animal body have an endocrine (intrasecretory) function.

In the course of their life they form both intermediate and end products of metabolism. In turn, the latter enter the intercellular fluid, blood, lymph and influence various physiological processes.

All waste products entering the bloodstream are carried throughout the body and regulate the processes occurring in organs and tissues. This is a humoral pathway of regulation (from the Latin word “humor” – liquid). These substances include products of endogenous origin, produced by the body itself, as well as substances entering the blood from outside.

The most important regulatory function is performed by the endocrine glands or individual clusters of cells that synthesize biologically active substances.

There are neurosecretory nuclei of the hypothalamus, nuclei of the medulla oblongata and midbrain, as well as endocrine glands – the pituitary gland, pineal gland, thyroid and parathyroid glands, adrenal glands, pancreas, glands of the reproductive system of males and females, cells of the thymus, kidneys, liver, digestive organs.

Pineal gland

The superior cerebral appendage, or pineal gland, is a formation of the diencephalon. Supports sexual development of the body and regulates sexual activity. Participates in the regulation of immune processes.

Pituitary gland

Located in the pituitary fossa of the sphenoid bone of the skull. It consists of two lobes: anterior and posterior. The anterior lobe produces hormones that regulate the secretion of all other endocrine glands.

• Growth hormone – regulates body growth
• Thyroid-stimulating hormone – acts on the thyroid gland and promotes the formation of thyroxine
• Adrenocorticotropic hormone – stimulates the adrenal cortex and ensures the secretion of cortisol
• Gonadotropic hormones:
  1. Follicle-stimulating hormone (FSH) – initiates the development of ovarian follicles, promotes the formation of spermatozoa in the testis
  2. Luteinizing Hormone (LH) – controls the secretion of estrogen and progesterone in the ovaries and testosterone in the testes
  3. Luteotropic (prolactin) hormone – regulates the secretion of milk and contributes to the preservation of the corpus luteum of pregnancy

The posterior pituitary gland produces:

• Anidiuretic (ADH) hormone – regulates the amount of fluid passing through the kidneys
• Oxytocin – stimulates uterine contractions during childbirth and promotes the formation of breast milk

In the anterior lobe of the pituitary gland, a narrow strip of glandular tissue is isolated – an intermediate lobe that produces the hormone – interomedin. This hormone is involved in the processes of pigmentation (coloration) of the skin and mucous membranes. An increase in the blood concentration of this hormone, the action of which is closely related to ACTH, is observed during pregnancy, bronze disease (Addison’s disease). Also involved in the processes of immunity.

Thyroid gland

It has two lobes located on both sides of the trachea and connected to each other by a strip of glandular tissue – the isthmus. Produces:

• Thyroxine (T4) and Triiodothyronine (T3), which regulate basal metabolism
• Thyrocalcitonin – regulates the exchange of calcium and phosphorus.

The secretory activity of the thyroid gland is regulated by the thyroid-stimulating hormone of the anterior pituitary gland. And directly thyroid hormones regulate the metabolism in organs and tissues.

Parathyroid glands

Located behind the lobes of the thyroid gland, in its capsule. They produce a hormone – parathyroid hormone, which regulates the exchange of calcium and phosphorus.

Thymus gland (thymus)

Located between the sternum and trachea. It is considered as the central organ of immunity, because. it is the maturation of T-lymphocytes responsible for cellular immunity.

The thymus hormone thymosin is an immunomodulator that affects carbohydrate metabolism, calcium metabolism and neuromuscular transmission. In adults, the thymus gland undergoes involution (reverse development).

Adrenal glands

Paired glands located above the poles of the kidneys. Each gland has a dense connective tissue capsule that penetrates into the gland and divides it into two layers: the outer (cortex) and the inner (medulla).

The cortex is divided into 3 zones that produce corticosteroids.

Glomerular zone (superficial), produces mineralocorticoids (aldosterone, deoxycorticosterone). They affect the water-salt metabolism and affect the kidneys. An excess of these hormones leads to water retention and increased blood pressure, and a deficiency leads to dehydration.

The fascicular zone (middle) secretes glucocorticoids (cortisone, corticosterone), which are powerful immunosuppressants and desensitizers. Also, glucocorticoids affect carbohydrate metabolism, stimulate the synthesis of glycogen in the muscles. Their role is great at high muscle tension, the action of superstrong stimuli.

Reticular zone, produces sex hormones – male (androgens) and female (estrogen and progesterone). They affect the development of the skeleton and the formation of secondary sexual characteristics. The production of hormones of the opposite sex is inhibited by the sex glands.

The adrenal medulla produces catecholamines – epinephrine and norepinephrine.

Adrenaline has an effect on the cardiovascular system, constricts peripheral vessels, inhibits the movement of the gastrointestinal tract, causes pupil dilation, restores the working capacity of tired muscles, enhances carbohydrate metabolism.

Norepinephrine helps to maintain the tone of blood vessels, participates in the transfer of excitation from nerve fibers to the innervated organs.

Pancreas

Gland with mixed secretion. Its endocrine part is the islets of Langerhans. These cells secrete a secret into the blood, that is, they are endocrine glands. The islets of Langerhans are made up of three types of cells: alpha, beta, and gamma. Beta cells produce the hormone insulin, alpha cells produce the hormone glucagon.

Insulin is a polypeptide hormone. Insulin sharply increases the permeability of the walls of muscle and fat cells for glucose, i.e. participates in the regulation of carbohydrate metabolism. It ensures the utilization of glucose by the body, the synthesis of glycogen (reserve carbohydrate) and its accumulation in muscle fibers. By increasing the flow of glucose into the cells of adipose tissue, insulin stimulates the formation of fat in the body. In addition, insulin also stimulates protein synthesis in the cell, increasing the permeability of cell walls to amino acids.

Lack of insulin in the body is the cause of diabetes.

Glucagon – the second hormone of the pancreas – stimulates the breakdown of glycogen to glucose inside cells (by activating the appropriate enzymes) and increases blood sugar. Glucagon also stimulates the breakdown of fat in adipose tissue. Thus, according to the results of its action, glucagon is an insulin antagonist.

Tissue hormones

Locally acting hormones (tissue hormones) are produced not by endocrine glands, but by specialized cells located in various organs. The physiological significance of these hormones lies in the fact that they control, first of all, the activity of the organ in which they are formed.

Hormones of the gastrointestinal tract – gastrin, cholecystokinin, secretin and pancreozymin. These are polypeptides secreted by the mucosa of the gastrointestinal tract in response to specific stimulation. For example, gastrin stimulates the secretion of hydrochloric acid; cholecystokinin controls the emptying of the gallbladder, and secretin and pancreozymin regulate the secretion of pancreatic juice; parotin, which is formed in the parotid salivary gland and affects the development of teeth, cartilage and bone tissue, etc.

Neurohormones are a group of chemical compounds secreted by nerve cells (neurons). These compounds have hormone-like properties, stimulating or inhibiting the activity of other cells; they include the releasing factors mentioned earlier, as well as neurotransmitters whose function is to transmit nerve impulses between cells. Neurotransmitters include dopamine, adrenaline, norepinephrine, serotonin, histamine, acetylcholine, and gamma-aminobutyric acid. In the mid-1970s, a number of new neurotransmitters with morphine-like analgesic effects were discovered; they got the name “endorphins”, i.e. “internal morphine”. Endorphins are able to bind to special receptors in brain structures; as a result of this binding, impulses are sent to the spinal cord, which block the transmission of incoming pain signals. The analgesic effect of morphine and other opiates is undoubtedly due to their similarity to endorphins, ensuring their binding to the same pain-blocking receptors.

In the practice of traditional medicine physicians and veterinarians, the use of hormones is becoming more widespread. The disorder of hormonal regulation plays an important role in the origin of many diseases of the nervous system, internal organs, motor apparatus (muscles, joints), skin, reproductive system. Therefore, treatment with hormonal drugs is an important component of the complex treatment of not only diseases of the endocrine glands, but also many other diseases.

An endocrinologist treats men with various diseases associated with hormonal and metabolic disorders, such as diabetes, thyroid disorders, sexual dysfunction, obesity and much more. Contact a specialist and get effective treatment!

Endocrinology is an important branch of medicine that deals with the study of endocrine glands and their hormonal activities. It is aimed at diagnosing and treating various diseases associated with disruption of the endocrine system.

An increase in the level of hormones, their deficiency or improper metabolism can lead to various diseases, including in men. Thus, an endocrinologist deals with the treatment of diseases of the thyroid gland, pituitary gland, adrenal glands and other endocrine glands.

The main disease treated by an endocrinologist in men is diabetes. It occurs when there is a lack of insulin or a deterioration in its action. Improper metabolism can lead to the development of obesity, atherosclerosis, diseases of the heart and blood vessels.

It should be noted that endocrinology not only treats diseases, but also deals with their prevention. A good specialist conducts not only medical procedures, but also teaches patients to eat right, lead a healthy lifestyle and monitor their hormonal levels.

Endocrinologist – a specialist in the treatment of diseases of the endocrine system in men

The male endocrine system consists of several glands, each of which secretes its own hormones – substances that control many processes in the body. These glands can produce insufficient amounts of hormones, which leads to various diseases.

An endocrinologist also treats other diseases such as thyroid disorders, hyperparathyroidism, hyperaldosteronism, hyperprolactinemia and many others. To diagnose and treat these diseases, the endocrinologist uses laboratory tests and computed tomography.

• One of the most common diseases associated with the endocrine system in men is hypogonadism. This disease is characterized by insufficient levels of testosterone, the hormone responsible for the development of male sexual characteristics.
• Endocrinologist also deals with the treatment of adipose tissue associated with metabolic disorders – metabolic syndrome.
• Schechter’s disease is a pathology associated with growth hormone deficiency, which is also treated by an endocrinologist.

It is important to understand that diseases associated with the endocrine system often do not show clear symptoms in the initial stages. Therefore, regular visits to the endocrinologist allows you to identify and treat these diseases in time, improving the quality of life of patients.

What problems can an endocrinologist treat in men

Diabetes mellitus

Endocrinologists treat diabetes in men. This is a chronic disease associated with insufficient use of insulin by the body. Uncontrolled diabetes can lead to serious complications such as nerve injury, kidney damage, and cardiovascular disease.

Hypogonadism

Endocrinologists treat hypogonadism in men. This is a condition where the testicles do not produce enough testosterone. Hypogonadism can lead to decreased libido, loss of muscle mass, and decreased bone density.

Obesity

Endocrinologists treat obesity in men. Obesity can lead to various diseases such as diabetes, cardiovascular disease and hypertension. Endocrinologists may prescribe diets and exercise, as well as medications to treat obesity.

Thyroid

Endocrinologists treat thyroid disorders in men. The thyroid gland produces hormones that control metabolism and energy levels in the body. Insufficient amounts of hormones can lead to decreased energy levels and metabolism, while excess hormones can lead to increased blood pressure and heart rate.

The endocrine system and its implications for health

The endocrine system is a system in the body that consists of endocrine glands that secrete substances directly into the blood. These substances, called hormones, regulate various functions in the body, affect metabolism, growth and development, reproductive areas and other processes.

An endocrinologist is a doctor who specializes in the treatment of diseases associated with disorders of the endocrine system. The doctor examines patients, reveals disorders of the endocrine glands, analyzes the level of hormones and much more. After that, the doctor prescribes treatment, which may include both medication regimens and recommendations for lifestyle and dietary changes.

The control and treatment of diseases caused by endocrine disruption is important to keep the body healthy and help the patient regain normal functions. Therefore, it is recommended to visit the endocrinologist regularly and conduct periodic examinations in order to identify possible disorders of the endocrine system at the very beginning of their manifestation and treat diseases in a timely manner.

Who needs to see an endocrinologist and when to do it

When a man has problems in the endocrine system, he should contact an endocrinologist. This specialist is engaged in the study of the work of the hormonal system of a man, as well as the diagnosis and treatment of diseases associated with a violation of its functions.

Some of the common problems that a man may experience that require a visit to an endocrinologist include: erectile dysfunction, deterioration in sperm quality, regular pain in the testicles, problems with urination, massive weight gain or weight loss, fatigue, and abnormal hair growth on the face or body. If a man has one or more of these symptoms, he should immediately contact an endocrinologist.

When seeing an endocrinologist, a man can expect a detailed medical examination, including blood tests and ultrasound of the thyroid and testicles. If necessary, the endocrinologist may prescribe an additional examination by other specialists. After receiving the results and conducting a detailed analysis, the endocrinologist plans treatment depending on the diagnosis. Treatment may include medication, surgery, or lifestyle adjustments as needed.

What studies reveal problems in the endocrine system in men?

Hormone testing. The level of hormones in the blood is the main indicator of the endocrine system. You can test for hormones such as testosterone, prolactin, cortisol, and thyroid-stimulating hormone to check for thyroid, pituitary, or gonadal problems.

1. Ultrasound examination (ultrasound). Ultrasound is an important method for detecting tumors and cysts of the endocrine system. This can be helpful in identifying thyroid, ovarian, or prostate problems.
2. MRI. Magnetic resonance imaging can capture tumors and cysts of the endocrine system in more detail than ultrasound. An MRI can also be used to detect problems with the pituitary, thyroid, or adrenal glands.
3. Thyroid scintigraphy. This method allows you to visualize the functioning of the thyroid gland. The patient is injected with a small amount of radioactive material, which is then scanned to determine the level of thyroid activity. This is a very useful test for determining hypothyroidism and hyperthyroidism.

Glycosylated hemoglobin. This test is used to detect diabetes. It measures the level of glycated hemoglobin in the blood, which shows how well your blood sugar has been managed over the past few months.

Examination of the liver. The liver plays a key role in hormone processing. If the liver is not working properly, it can lead to problems in the endocrine system. Tests that are used to measure liver function include aminotransferases, alkaline phosphatase, and bilirubin.

Medicines for the treatment of endocrine problems in men

Endocrine problems in men may be related to the production or function of hormones. Various medications can be used to treat these problems.

Preparations for the treatment of testosterone deficiency

Testosterone deficiency can lead to a violation of a number of functions in the body. For treatment, you can use testosterone preparations – injections, gels and tablets. These drugs can increase testosterone levels in the body and improve sexual function, increase muscle mass, and improve mood.

Drugs for the treatment of hyperthyroidism

Hyperthyroidism is a condition characterized by an excess of thyroid hormones. Treatment may include antithyroid drugs, which lower the levels of thyroid hormones in the body. These drugs can relieve symptoms of hyperthyroidism, such as rapid heart rate and nervousness.

Diabetes drugs

Diabetes is a disease in which blood sugar levels are elevated. Treatment may include insulin medications, which lower blood sugar levels, and medications that improve the body’s sensitivity to insulin. These drugs help control blood sugar levels and prevent the complications of diabetes.

• Each drug should be prescribed by a doctor depending on the diagnosis and condition of the patient
• Instructions for use of drugs should be strictly followed
• Endocrinologist should be consulted before starting treatment

Healthy lifestyle and diet to maintain the endocrine system in men

The importance of proper nutrition

Proper and balanced nutrition is an important factor in maintaining the health of the endocrine system in men. Excessive consumption of fatty and salty foods, sweets, carbonated drinks can adversely affect the functioning of the thyroid gland and pancreas. It is recommended to eat more vegetables and fruits, bread, legumes, fish, avoid smoked meats, fatty meat dishes, canned foods.

The right amount of water

Drinking enough water is also important for maintaining a healthy endocrine system in men. Lack of fluid can lead to a slowdown in the functioning of all glands in the body. It is recommended to consume at least 1.5-2 liters of water per day.

Physical activity

Lack of sufficient physical activity can also lead to disruption of the endocrine system in men. It is recommended to play sports, exercise, walk, climb stairs instead of a lift. However, excessive physical activity should be avoided, as it can backfire and have a negative impact on health.

Negative impact of bad habits

Nicotinism, alcoholism and drug addiction negatively affect the work of the endocrine system of men and can lead to serious disorders, such as reduced potency, sleep disturbance, heart problems. Therefore, it is recommended to avoid these bad habits and abandon them.

The value of good sleep

Good and regular sleep is of great importance in maintaining the health of the endocrine system in men. Lack of sleep can lead to disruption of the hormonal system and a decrease in testosterone levels in the blood. It is recommended to sleep at least 7-8 hours a day.

What is recommended to include in the diet to maintain the health of the endocrine system in menFoodsUseful properties

Hormonal imbalance: causes and treatment high or too low. This condition can lead to various diseases in both women and men.

A variety of methods can be used to treat hormonal imbalances in men, including drug therapy, lifestyle and dietary changes, and surgery if surgery is required. Often used hormonal drugs that can help normalize the level of hormones in the blood. In addition, men may be advised to make lifestyle changes, such as increasing physical activity and reducing alcohol and nicotine use. In some cases, especially with tumors and certain diseases, surgery may be required.

• Drug therapy – includes the use of hormonal drugs, as well as drugs that improve the functioning of the thyroid gland and pancreas.
• Diet and lifestyle changes – Helps reduce stress levels in the body and may improve endocrine function. It is recommended to increase the amount of fruits and vegetables, as well as reduce the intake of fatty and overly sweet foods.
• Surgery – may be indicated in cases where it is necessary to remove certain tumors that interfere with the normal functioning of the endocrine system.

Difficulties in treating endocrine system problems in men

High hormone levels

One of the main difficulties in treating endocrine system problems in men is high hormone levels. This can happen if there is a malfunction of the thyroid gland or pancreas. It is necessary to carry out an accurate diagnosis and apply effective treatment, since an overestimated level of hormones can lead to serious disorders in the body.

Focusing on the symptoms rather than the cause

Another difficulty is focusing on the symptoms rather than the cause of the problem. Typically, instead of investigating the root cause of an endocrine disorder, doctors often simply prescribe hormone therapy. For effective treatment, it is necessary to establish the causes and direct treatment to eliminate them.

Negative impact of lifestyle on health

The third difficulty is the negative impact of lifestyle on health. Overeating, smoking, drinking alcohol and lack of physical activity are the main causes of various diseases, including endocrine diseases. Doctors should also advise patients to change their lifestyle in order to successfully fight endocrine disorders.

The dependence of the effectiveness of treatment on the patience and diligence of the patient

Finally, it should be noted that the effectiveness of the treatment of endocrine disorders in men depends very much on the patience and diligence of the patient. Irregular medication, poor nutrition, and skipping doctor appointments can seriously undermine the effectiveness of treatment. Therefore, it is very important that patients treat their treatment responsibly and always follow the doctor’s prescriptions.

Complications of ignoring endocrine problems in men

1. Violations of sexual dysfunction. One of the most obvious manifestations of endocrine disorders in men are problems with potency, decreased libido and reduced erectile function. As you age, these problems can only get worse if you don’t see a doctor and start treatment.

2. Development of atherosclerosis. It is scientifically proven that endocrine disorders in men can lead to accelerated development of atherosclerotic plaques, which in turn can lead to coronary heart disease and myocardial infarction. This is especially true for older men.

3. Various metabolic disorders. Osteoporosis, diseases of the metabolism of fats and carbohydrates, diabetes – all this may be associated with endocrine system disorders in men.

4. Problems with the thyroid gland. The thyroid gland is very important for the body’s metabolism. Thyroid disorders in men can lead to low energy, depression, and overweight.

5. Development of tumors of the endocrine glands. If disturbances in the endocrine system of men continue for a long time, this can lead to the development of tumors of the endocrine glands, such as the thyroid gland or pancreas.

How to maintain men’s endocrine health at home

Balanced nutrition

Diet plays an important role in men’s endocrine health. Eat enough protein and avoid fatty and overly sweet foods. Vegetables, fruits and grains should be present in the diet, as they contain the necessary vitamins and minerals.

Active lifestyle

Lack of movement and increased weight can lead to endocrine disruption. Regular exercise will help keep the male hormonal system healthy. It is recommended that you get at least 30 minutes of physical activity a day, such as running, walking, swimming, or yoga.

Stress avoidance

Stress can disrupt the endocrine system, which in turn can lead to disease. Men should avoid stress and find ways to reduce it. For example, read a book or listen to music, meditate or take deep breaths.

Regular check-ups with an endocrinologist

A visit to an endocrinologist is essential to maintain the health of the male endocrine system. Regular checks will allow you to identify possible violations at an early stage and take measures to avoid the development of diseases.

Proper sleep

Insufficient sleep can have a negative effect on the health of the male hormonal system. The average man needs at least 7 hours of sleep per night. In addition, you need to make sure that the quality of sleep is also good. It is best to go to bed and wake up at the same time every day. This normalizes the work of the endocrine system.

Where to Find a Professional Endocrinologist to Treat Men’s Problems

When men have problems with hormonal balance, many of them turn to an endocrinologist, a doctor who diagnoses, treats, and prevents diseases of the endocrine system. If you need such a doctor and don’t know where to find one, the following tips will come in handy.

Secondly, try searching on specialized health portals, where there are sections and forums dedicated to the problems of the male endocrine system and the search for endocrinologists. Here you can find out about the best specialists in your city or region.

Thirdly, ask your family doctor for advice. He can advise you on a good endocrinologist and even refer you to him for treatment. If you live in a small town, your doctor may recommend a specialist in a nearby town.
