What Is It, Functions, Organs & Conditions

The endocrine system is a network of glands and organs located throughout the body. It’s similar to the nervous system in that it plays a vital role in controlling and regulating many of the body’s functions.

However, while the nervous system uses nerve impulses and neurotransmitters for communication, the endocrine system uses chemical messengers called hormones.

Keep reading to discover more about the endocrine system, what it does, and the hormones it produces.

The endocrine system is responsible for regulating a range of bodily functions through the release of hormones.

Hormones are secreted by the glands of the endocrine system, traveling through the bloodstream to various organs and tissues in the body. The hormones then tell these organs and tissues what to do or how to function.

Some examples of bodily functions that are controlled by the endocrine system include:

• metabolism
• growth and development
• sexual function and reproduction
• heart rate
• blood pressure
• appetite
• sleeping and waking cycles
• body temperature

What is a gland?

A gland is an organ that creates and releases substances that the body needs to function. There are two types of glands:

• endocrine glands, which release hormones directly into the bloodstream
• exocrine glands, like lymph nodes and sweat glands, which are not part of the endocrine system

The glands of the endocrine system are where hormones are produced, stored, and released. Each gland produces one or more hormones, which go on to target specific organs and tissues in the body.

The glands of the endocrine system include the:

• Hypothalamus. While some people don’t consider it a gland, the hypothalamus produces multiple hormones that control the pituitary gland. It’s also involved in regulating many functions, including sleep-wake cycles, body temperature, and appetite. It can also regulate the function of other endocrine glands.
• Pituitary. The pituitary gland is located below the hypothalamus. The hormones it produces affect growth and reproduction. They can also control the function of other endocrine glands.
• Pineal. This gland is found in the middle of your brain. It’s important for your sleep-wake cycles.
• Thyroid. The thyroid gland is located in the front part of your neck. It’s very important for metabolism.
• Parathyroid. Also located in the front of your neck, the parathyroid gland is important for maintaining control of calcium levels in your bones and blood.
• Thymus. Located in the upper torso, the thymus is active until puberty and produces hormones that are important for the development of a type of white blood cell called a T cell.
• Adrenal. One adrenal gland can be found on top of each kidney. These glands produce hormones that are important for regulating functions such as blood pressure, heart rate, and stress response.
• Pancreas. The pancreas is located in your abdomen behind your stomach. Its endocrine function involves controlling blood sugar levels.

Some endocrine glands also have non-endocrine functions. For example, the ovaries and testes produce hormones, but they also have the non-endocrine function of producing eggs and sperm, respectively.

Hormones are the chemicals the endocrine system uses to send messages to organs and tissue throughout the body. Once released into the bloodstream, hormones travel to their target organ or tissue, which has receptors that recognize and react to the hormone.

Below are some examples of hormones that are produced by the endocrine system.

Explore the interactive 3-D diagram below to learn more about the endocrine system.

Sometimes, hormone levels can be too high or too low. When this happens, it can have a number of effects on your health. The signs and symptoms depend on the hormone that’s out of balance.

Here’s a look at some conditions that can affect the endocrine system and alter your hormone levels.

Hyperthyroidism

Hyperthyroidism happens when your thyroid gland makes more thyroid hormone than necessary. This can be caused by a range of things, including autoimmune conditions.

Some common symptoms of hyperthyroidism include:

• fatigue
• nervousness
• weight loss
• diarrhea
• issues tolerating heat
• fast heart rate
• trouble sleeping

Treatment depends on how severe the condition is, as well as its underlying cause. Options include medications, radioiodine therapy, or surgery.

Graves‘ disease is an autoimmune disorder and a common form of hyperthyroidism. In people with Graves‘ disease, the immune system attacks the thyroid, which causes it to produce more thyroid hormone than usual.

Hypothyroidism

Hypothyroidism occurs when your thyroid doesn’t produce enough thyroid hormone. Similar to hyperthyroidism, it has many potential causes.

Some common symptoms of hypothyroidism include:

• fatigue
• weight gain
• constipation
• issues tolerating the cold
• dry skin and hair
• slow heart rate
• irregular periods
• fertility issues

Treatment for hypothyroidism involves supplementing your thyroid hormone with medication.

Cushing syndrome

Cushing syndrome happens due to high levels of the hormone cortisol.

Common symptoms of Cushing syndrome include:

• weight gain
• fatty deposits in the face, midsection, or shoulders
• stretch marks, particularly on the arms, thighs, and abdomen
• slow healing of cuts, scrapes, and insect bites
• thin skin that bruises easily
• irregular periods
• decreased sex drive and fertility in males

Treatment depends on the cause of the condition and can include medications, radiation therapy, or surgery.

Addison’s disease

Addison’s disease happens when your adrenal glands don’t produce enough cortisol or aldosterone. Some symptoms of Addison’s disease include:

• fatigue
• weight loss
• abdominal pain
• low blood sugar
• nausea or vomiting
• diarrhea
• irritability
• a craving for salt or salty foods
• irregular periods

Treatment for Addison’s disease involves taking medications that help replace the hormones your body isn’t producing enough of.

Diabetes

Diabetes refers to a condition in which your blood sugar levels aren’t regulated within a certain range.

People with diabetes have too much glucose in their blood (high blood sugar). There are two types of diabetes: type 1 diabetes and type 2 diabetes.

Some common symptoms of diabetes include:

• fatigue
• increased hunger or thirst
• frequent urge to urinate
• irritability
• frequent infections

Treatment for diabetes can include blood sugar monitoring, insulin therapy, and medications. Lifestyle changes, such as getting regular exercise and eating a balanced diet, can also help.

Polycystic ovary syndrome (PCOS)

This common condition is caused by unbalanced reproductive hormones in people with ovaries, which can create issues in the ovaries. Living with PCOS can mean that an egg may not be released every month, or may not develop as it should when it is released.

Some of the common symptoms of PCOS are:

• irregular periods
• fertility issues
• cysts that form on the ovaries
• acne
• hirsutism, which is an unusual amount of hair growth on the face or chin
• thinning hair
• weight gain
• skin tags

Treatment for PCOS focuses on easing the symptoms. Treatments include medications, like birth control and metformin, and lifestyle changes, such as focusing on nutrition and trying to reach a moderate weight if your doctor has recommended it.

Hypogonadism

A common condition, especially in older males and occasionally in females, hypogonadism is caused by a lowered production of the sex hormone testosterone. This can lead to lowered libido, as well as a variety of other symptoms, such as:

• erectile dysfunction in people with a penis
• reduced energy
• reduced muscle mass
• depressed mood
• increased irritability

Treatment for hypogonadism focuses on improved testosterone levels. Testosterone replacement therapy and lifestyle changes (such as working toward a moderate weight if your doctor has recommended it) are two popular methods.

Osteoporosis

Osteoporosis is an abnormal loss of bone mass and changes in bone tissue. It can be caused by a variety of issues, but two common causes are lowered estrogen levels in people with ovaries and lowered testosterone levels in people with testicles. These lowered hormone levels can be caused by age, as well as other diseases.

Osteoporosis doesn‘t always cause obvious symptoms. But some of the more common symptoms are bone fractures and injuries related to minor falls, lifting, and even coughing.

Treatment for osteoporosis focuses on slowing or stopping bone loss. Proper nutrition, exercise, and medications are three of the most common treatments.

Acromegaly

This rare disease is caused when the body makes too much growth hormone, which is mainly produced in the pituitary gland. Mostly diagnosed in middle-aged adults, it can cause organs, bones, cartilage, organs, and certain tissues to grow in size.

The common symptoms of acromegaly include:

• swollen nose
• swollen ears
• swollen hands and feet
• joint aches
• a deeper voice than usual
• an increase in sweating and body odor

Treatment for acromegaly includes medications, radiation therapy, and surgery.

The endocrine system is a complex collection of glands and organs that helps regulate various bodily functions. This is accomplished through the release of hormones, or chemical messengers, produced by the endocrine system.

Endocrine system: Functions and potential conditions

The endocrine system is the name for the glands that produce hormones in a person’s body. These glands include the thyroid gland, pituitary gland, and adrenal gland. The endocrine system produces hormones such as insulin, estrogen, testosterone, and adrenaline.

The endocrine system produces and secretes a number of hormones in the body. These hormones play a vital role in many functions.

There are several different glands that make up the endocrine system. These glands produce and send hormones into the bloodstream, where they travel to different tissues in the body.

If the glands do not function properly and produce incorrect amounts of hormones, a person can develop certain disorders of the endocrine system.

This article discusses the endocrine system, its functions, the different glands present in the system, and certain endocrine disorders and diseases.

Sex and gender exist on spectrums. For this article, we use “male” and “female” to refer to a person’s sex assigned at birth.

Hormones are chemical messengers that enter the bloodstream and travel to specific areas of the body. These hormones then act on an organ or other cells in order to play a role in certain bodily functions.

Certain glands throughout the body make these hormones. The endocrine system is the name for this collection of glands.

The hormones that the endocrine system creates play a role in the following bodily functions:

• respiration
• metabolism
• reproduction
• sensory perception
• movement
• sexual development
• growth

Hormones can travel to all areas of the body. However, they only target cells that have compatible receptors. These cells are equipped to respond to the hormone and carry out certain functions when they come in contact with the hormone.

Hormones act by binding to certain receptors within cells. When a hormone binds to a receptor, the receptor then carries out the hormone’s instructions.

Different glands within the body produce different hormones. These different hormones all have a number of varying functions.

Below is a list of different glands and organs within the endocrine system.

Hypothalamus

The hypothalamus is present in the brain. It coordinates the endocrine system and links it with the nervous system.

The hypothalamus receives signals from various parts of the brain. It then releases and inhibits hormones based on these signals.

These hormones then act on the pituitary gland, which in turn directs the actions of several other glands in the body.

The hypothalamus releases hormones that play a role in:

• body temperature regulation
• appetite
• weight gain
• mood
• sex drive
• sleep
• thirst

Pituitary gland

The pituitary gland is located at the base of the brain. It is sometimes known as the “master gland” because it plays a role in so many bodily functions.

The pituitary gland releases hormones that travel throughout the body. These hormones either direct certain processes within the body or stimulate other glands to produce other hormones.

The pituitary gland produces the following hormones:

• Prolactin: This hormone stimulates breast milk production after childbirth. High levels of prolactin can affect hormones that control the ovaries in females and the testes in males. Prolactin can affect menstrual periods, sexual functionality, and fertility.
• Growth hormone (GH): This hormone stimulates growth in childhood. It also plays a role in maintaining healthy muscles and bones in people of all ages. GH also affects fat distribution around the body.
• Adrenocorticotropin (ACTH): This hormone causes the adrenal gland to produce cortisol. Cortisol helps maintain blood pressure and blood sugar levels. Cortisol is sometimes known as a “stress hormone.” The body produces large amounts of it when a person is under stress.
• Thyroid stimulating hormone (TSH): This hormone causes the thyroid gland to produce hormones that regulate the body’s metabolism, energy balance, growth, and nervous system activity.
• Luteinizing hormone (LH): This hormone stimulates the production of testosterone in males and egg release in females.
• Follicle stimulating hormone (FSH): This hormone stimulates the production of sperm in males. It also causes the ovaries to produce estrogen and develop eggs in females.
• Antidiuretic hormone (ADH): This hormone is made in the hypothalamus but stored and released from the posterior pituitary gland. It regulates water balance in the body. It also regulates sodium levels in the blood. ADH can conserve water in the body by reducing the amount of water a person loses in their urine.
• Oxytocin: This hormone causes milk to flow during breastfeeding and can help labor progress during childbirth. It is also made in the hypothalamus but stored and released from the posterior pituitary gland.

Parathyroid gland

The parathyroid gland is a group of four small glands that sits behind the thyroid gland. This gland produces the parathyroid hormone (PTH).

PTH facilitates the creation of active vitamin D in the kidneys. This helps control a person’s calcium and phosphorous levels. This makes PTH vital for bone development and health.

Pancreas

The pancreas is a gland organ that is situated in the abdomen. The main function of the pancreas is to maintain healthy blood sugar levels.

Below are the two main hormones that the pancreas produces:

• Insulin: Insulin is a hormone that allows cells in a person’s muscles, fat, and liver to absorb glucose in the blood, preventing blood sugar levels from getting too high. This allows the glucose to provide these cells with energy. Insulin can also affect the breakdown of fat or protein.
• Glucagon: This hormone prevents blood sugar levels from dropping too low. It causes the liver to convert stored blood sugar into a usable form before releasing it into the bloodstream. Glucagon also stops the liver from storing glucose, meaning more remains in the blood.

Thyroid

The thyroid is located in the front of a person’s neck. This gland plays an important role in controlling a person’s metabolism.

The hormones that the thyroid produces affect the way the body uses energy, consumes oxygen, and produces heat.

Adrenal gland

The adrenal glands are located at the top of both kidneys. These glands produce hormones such as:

• glucocorticoids, including cortisol
• mineralocorticoids
• adrenal androgens
• catecholamines, such as:
  • epinephrine, also known as adrenaline
  • norepinephrine

These hormones can help the body with the following functions:

• helping maintain proper cardiovascular function
• helping a person respond well to stressful situations
• promoting the proper use of carbohydrates and fats
• distributing stored fat
• producing body odor and pubic hair
• promoting a healthy gastrointestinal system

Pineal gland

The pineal gland is located in the brain. It produces the hormone melatonin.

Melatonin influences the rhythm of sleep by helping the body recognize when it is time to go to sleep.

Ovaries

Ovaries are present in females. They are located in the lower left and right quadrants of the abdomen.

The ovaries produce eggs as well as hormones such as:

• estrogen
• testosterone
• progesterone

These hormones play a vital role in the following processes:

• reproductive organ development
• breast development
• bone health
• pregnancy
• fertility

Testes

These glands are present in males and are situated in the scrotum.

The testes produce the hormone testosterone. Testosterone promotes the growth of the penis as the person gets older, as well as the growth of facial hair and body hair.

Testosterone also plays a role in deepening the person’s voice as they reach a certain age. It also helps:

• maintain a person’s sex drive
• promote the production of sperm
• maintain muscle mass
• maintain bone mass

When the endocrine system produces incorrect amounts of certain hormones, a person may develop different kinds of conditions. Below are some disorders of the endocrine system.

Diabetes

Diabetes is a condition where the body does not properly control the levels of sugar in the bloodstream.

Diabetes occurs when the pancreas does not produce enough insulin or the body does not effectively use the insulin that it does produce. There are different types of diabetes.

Common symptoms of diabetes include:

• frequent urination
• constantly feeling thirsty
• feeling more tired than usual
• sudden weight loss
• blurred vision
• increased appetite

A person can manage their diabetes with certain medications and dietary changes.

If a person does not manage their diabetes, it can lead to a number of complications, including:

• dental and gum diseases
• eye issues and loss of sight
• foot problems, including numbness, leading to ulcers
• heart disease
• nerve damage, such as diabetic neuropathy
• stroke
• kidney disease

Cushing’s syndrome

Cushing’s syndrome occurs when the endocrine system produces too much of the hormone cortisol.

Common symptoms of Cushing’s syndrome include:

• weight gain
• thin arms and legs
• a round face
• increased fat at the base of the neck
• a fatty hump that develops between the shoulders
• bruising more easily
• muscle weakness
• the presence of wide, purple stretch marks, commonly on the:
  • abdomen
  • breasts
  • hips
  • under the arms

Complications of Cushing’s syndrome include:

• heart attack
• stroke
• blood clots in the legs and lungs
• infections
• bone loss and fractures
• high blood pressure
• unhealthy levels of cholesterol
• depression
• memory loss
• trouble concentrating
• insulin resistance and prediabetes
• type 2 diabetes

Adrenal insufficiency and Addison’s disease

If a person has adrenal insufficiency, then their adrenal glands do not make enough of certain hormones.

Addison’s disease is a type of adrenal deficiency. It occurs when a person’s adrenal glands are damaged and do not make enough cortisol and sometimes aldosterone.

Adrenal insufficiency can affect the way a person’s body responds to stress. It can also affect the way a person’s body maintains other functions that may be essential.

Common symptoms of adrenal insufficiency include:

• fatigue
• muscle weakness
• loss of appetite
• weight loss
• abdominal pain

If a person has adrenal insufficiency, the correct treatment can help them to lead an active, typical life.

Overactive thyroid

If a person has an overactive thyroid, then their thyroid gland produces too many hormones.

Hyperthyroidism is another name for an overactive thyroid. By producing too much of certain hormones, an overactive thyroid can cause symptoms such as:

• nervousness
• irritability
• the inability to relax
• feeling warm
• heat intolerance
• sweating
• heart palpitations
• fatigue
• increased frequency of bowel movements
• increased appetite
• weight loss

There are several possible causes of an overactive thyroid, including:

• an autoimmune thyroid disease
• a toxic thyroid nodule
• thyroid inflammation
• the use of certain drugs to treat other conditions

With the right treatment, a person can live a typical life. However, without treatment, an overactive thyroid can cause a number of complications. These include heart dysfunction and heart failure, strokes, and osteoporosis.

Other endocrine system disorders

Other endocrine system disorders include:

• gigantism
• hypothyroidism
• multiple endocrine neoplasia type 1 and 2
• polycystic ovary syndrome
• precocious puberty

If a person believes they may have an endocrine disorder, they should speak with a doctor. An accurate diagnosis can help a person begin treatment, which may improve symptoms.

Often, treatment for an endocrine disorder can reduce a person’s risk of developing complications associated with that disorder.

The endocrine system is the name for the glands in the body that produce hormones. These glands include the thyroid gland, pituitary gland, and adrenal gland.

The endocrine system produces hormones, including insulin, estrogen, testosterone, and adrenaline.

These hormones play a role in a number of functions, including respiration, metabolism, reproduction, sensory perception, sexual development, and growth.

If the glands do not function properly, then they may produce incorrect amounts of hormones. This can cause a person to develop certain endocrine system disorders.

Examples of endocrine system disorders include diabetes, hyperactive thyroid, adrenal insufficiency, and Cushing’s syndrome.

Thyroid functions

Location and size of the thyroid gland

The thyroid gland is located in the front of the neck, slightly
below the Adam’s apple. It covers the trachea, as if
butterfly spread its wings. Its size is about 4 cm
in height and weight up to 20 g.
The thyroid gland is a very thin and soft organ. IN
Normally, it cannot be detected
touching the neck, but even a slight swelling is good
palpable. Larger swelling is clearly visible
to the naked eye.

The body produces different types of hormones (female
hormones, male hormones, adrenal hormones, etc.).
Organs that produce hormones are called endocrine
organs, and the thyroid gland is one of them. Her
function is to produce thyroid hormones from
iodine contained in food (mainly in marine
algae).

What are thyroid hormones

Food proteins, fats and
carbohydrates are metabolized and used
as materials for tissue formation or as
energy for the body. Thyroid hormones function
stimulation or intensification of these metabolic processes
substances. In addition, they play an important role in the development of the fetus and
the growth of the child’s body.

There are two types of thyroid hormones: thyroxine (T4),
containing four iodine atoms, and triiodothyronine (T3) containing
three iodine atoms.

The thyroid gland produces mainly
Thus, T4, which is transformed into T3 in the liver and other
organs and performs its function as a hormone.

Most T4 and T3 are bound to plasma proteins.
The hormones that act in the body are free T4 (Free
T4=FT4) and free T3 (Free T3=FT3), not associated with proteins
blood, which are tested in a blood test.

Functions of the pituitary gland

The body has a mechanism to maintain
almost constant level of thyroid hormones in
blood. This system is controlled by thyroid stimulating hormone.
(TSH), which is produced by part of the brain –
pituitary gland. This hormone has the function of stimulating
thyroid gland and inducing the production of thyroid
hormones (T4, T3).

If the level of thyroid hormones (T4, T3) in the blood
becomes too high, the amount allocated
pituitary TSH decreases, which reduces the production of T4 and
T3. On the other hand, with a decrease in the concentration of T4 and T3 in
the amount of TSH secreted in the blood increases, stimulating
secretion of T4 and T3. This system is called the “mechanism
feedback” and constantly regulates the level of thyroid
hormones in the blood within a certain range.

The endocrine system is one of the most important systems in the body, which controls, coordinates and integrates the processes occurring in our body. The endocrine system is a complex group of endocrine glands that produce hormones. Hormones control the work of almost all organs and systems: reproductive function, the cardiovascular system, the emotional sphere, the work of the gastrointestinal tract, metabolic processes, the condition of the skin, the growth and development of the body, and much more.

Hormones are also responsible for the body’s interaction with the environment and help meet energy and nutrient needs. The organs that make up the endocrine system include the thyroid, parathyroids, pancreas, ovaries, testes, adrenals, pituitary, and hypothalamus.

If any component of hormonal regulation falls out of the general tuned system, then a single chain of regulation of the functions of the human body is disrupted and various pathological conditions develop. Any disturbances in the functioning of the endocrine system can have the most dangerous consequences, which can be avoided by the timely appointment of an endocrinologist.

An endocrinologist is a physician who diagnoses, prevents and treats diseases of the endocrine system. The appointment of an endocrinologist is necessary in the treatment of diseases associated with a violation of the level of hormones, problems of weight gain or decrease, malfunctions of various body systems.

What are the symptoms that indicate malfunctions of the endocrine system and the need to visit an endocrinologist? In what cases is it impossible to do without the intervention of this specialist?

Manifestations of endocrine diseases are very diverse. You will need a consultation and appointment with an endocrinologist if you are worried about frequent mood changes, excessive fatigue, tearfulness and depression. These are states that indicate that a failure has occurred in the endocrine system.

Changes in appearance may also be a reason to visit a doctor: overweight or its extreme thinness, hair loss or, conversely, excessive body hair, loss of teeth, soft nails, excessively dry skin.

Headaches, high blood sugar, hearing loss and memory loss are another reason to listen to your body and consult an endocrinologist. Dry mouth, constant thirst, burning eyes, cramps in the calf muscles should encourage a person to take care of their health.

Diagnosis of diseases of the endocrine glands is often a difficult task for a general practitioner, since the action of hormones affects all human organs and systems. Therefore, the endocrinologist is engaged in the diagnosis of hormonal disorders.

What are the most common endocrine diseases?

Diabetes mellitus

Patients with diabetes have an excess of sugar in the blood. In this disease, the production or action of the hormone insulin is impaired. Diabetes mellitus is one of the most common diseases in the world. Recent studies have shown that blood sugar control can prevent serious complications of diabetes such as nephropathy, retinopathy, polyneuropathy and avoid blindness, kidney failure, hemodialysis and limb amputations. An endocrinologist treats diabetes with specific dietary guidelines and medications, including insulin. He also works closely with the patient to control blood sugar and prevent and treat complications.

Thyroid disorders

Patients with thyroid disorders often have problems with their metabolic rate (metabolism). With such diseases, mood is disturbed, weight control is disturbed, the perception of cold and heat changes. An endocrinologist treats diseases associated with excessive (hyperthyroidism) or insufficient (hypothyroidism) production of thyroid hormones. An endocrinologist helps patients achieve hormonal balance by blocking or replacing thyroid hormone function. An endocrinologist also deals with enlarged thyroid problems (diffuse goiter), autoimmune thyroid diseases, and thyroid cancer.

Osteoporosis

Endocrinologist diagnoses conditions of bone softening (osteomalacia, rickets) and reduced bone density (osteoporosis). Osteoporosis is a disease that leads to a decrease in the strength of your skeleton, which can manifest as bone pain and fractures. Certain body hormones protect bone tissue from destruction. With the appearance of hormonal disorders of mineral metabolism, the bones begin to lose calcium and become brittle. Age-related changes – menopause in women and andropause in men – are risk factors for osteoporosis and fractures. The endocrinologist also treats other causes of osteoporosis, such as overactive parathyroid glands (hyperparathyroidism) or long-term use of corticosteroids (such as prednisolone).

Overweight and obesity

Sometimes weight problems are the result of hormonal imbalances. Dysfunction of the thyroid gland, adrenal glands, pituitary gland and gonads can cause obesity. In addition to treating obesity, an endocrinologist identifies obesity-related risk factors such as insulin resistance and genetic disorders.

Pituitary gland

The pituitary gland is often called the main endocrine organ, since it controls the work of the other endocrine glands. The pituitary gland produces a large number of important hormones. Disruption of the pituitary gland can cause hormonal imbalance and lead to infertility, menstrual irregularities, growth disorders (acromegaly, gigantism, dwarfism), excessive production of glucocorticoids by the body (Cushing’s disease). The endocrinologist treats these conditions with medication and/or refers to a surgeon.

Height

Both children and adults can have growth hormone (somatotropin) problems. With its insufficient production by the pituitary gland, dwarfism develops in childhood. With a lack of somatotropin in adults, fatigue, lethargy, depression, and disruption of the organs develop. Safe and effective growth hormone replacement therapy is available for these patients. Excess production of growth hormone by the pituitary gland in childhood leads to gigantism, in adulthood to acromegaly. Excessive production of somatotropin affects all organs and tissues, disrupts their work, increases the risk of cancer. Usually, endocrinologists treat acromegaly in conjunction with surgeons.

Hypertension

Hypertension is high blood pressure and is a risk factor for cardiovascular disease. The reasons for the increase in pressure are different. About 10% of the increase in pressure is associated with excessive production of the hormone aldosterone by the adrenal glands. Half of these cases are associated with formations in the adrenal glands, which must be surgically removed. Overproduction of adrenaline by the adrenal glands (pheochromocytoma) also leads to a significant increase in blood pressure, even at a young age. All these diseases are successfully treated by endocrinologists.

Cholesterol disorders

Patients with lipid disorders have problems with normal levels of adipose tissue in the body. One of the most common problems is an increase in total cholesterol (hypercholesterolemia), low-density cholesterol (“bad” cholesterol, LDL), an increase in triglycerides (TG) in the blood. High levels of these fats in the blood can cause coronary heart disease, heart attacks and strokes, and circulatory disorders in the limbs.

An endocrinologist identifies factors that can cause lipid disorders such as hypothyroidism, drug side effects (corticosteroids), genetic or metabolic causes (metabolic syndrome, polycystic ovary syndrome, obesity). Lipid metabolism disorders are successfully treated with special diets and drugs.

In case of hypothalamic-pituitary diseases:

in case of diabetes insipidus, symptoms are manifested in polyuria, polydipsia, sleep disturbance, and also in hyperprolactinemia syndrome, galactorrhea, frigidity, decreased libido, decreased appetite are observed.

If you have any signs of the above listed endocrine diseases, or found an increased or decreased level of hormones during the test, hurry up for a consultation with an endocrinologist. In addition, do not forget to undergo an annual thyroid ultrasound as a preventive measure, and if there are increased risks, donate blood to determine the level of thyroid hormones.
