What are the main hormones produced by the adrenal glands. How do adrenal hormones affect the body’s metabolism and stress response. What role do adrenal hormones play in regulating blood pressure and electrolyte balance. How do adrenal hormones influence reproductive function and sexual characteristics.

The Structure and Function of the Adrenal Glands

The adrenal glands, small but mighty endocrine organs situated atop each kidney, play a crucial role in maintaining the body’s homeostasis. These glands are composed of two distinct parts: the outer adrenal cortex and the inner adrenal medulla. Each section produces specific hormones that regulate various bodily functions, from metabolism and stress response to blood pressure and sexual characteristics.

Adrenal Cortex: The Hormone Powerhouse

The adrenal cortex is further divided into three layers, each responsible for producing different types of hormones:

• Zona glomerulosa (outer layer): Produces mineralocorticoids
• Zona fasciculata (middle layer): Produces glucocorticoids
• Zona reticularis (inner layer): Produces androgens and small amounts of estrogen

This layered structure allows the adrenal cortex to efficiently produce and regulate the release of various hormones in response to the body’s needs.

Adrenal Medulla: The Stress Response Center

The adrenal medulla, while smaller than the cortex, plays a vital role in the body’s fight-or-flight response. It primarily produces catecholamines, which act as both hormones and neurotransmitters.

Cortisol: The Stress Hormone and Metabolic Regulator

Cortisol, often referred to as the “stress hormone,” is a glucocorticoid produced by the zona fasciculata of the adrenal cortex. Its production is regulated by the hypothalamic-pituitary-adrenal (HPA) axis, which responds to various internal and external stressors.

Cortisol’s Multiple Functions

How does cortisol affect the body’s metabolism? Cortisol plays a crucial role in:

• Regulating blood sugar levels by promoting gluconeogenesis
• Facilitating the breakdown of proteins and fats for energy
• Suppressing the immune system to prevent overactivity
• Maintaining cardiovascular function and blood pressure

During periods of stress, cortisol levels rise, preparing the body for action by increasing blood sugar, enhancing brain function, and reducing non-essential bodily processes.

The Circadian Rhythm of Cortisol

Cortisol production follows a diurnal pattern, with levels typically highest in the early morning and lowest around midnight. This rhythm is essential for maintaining normal sleep-wake cycles and overall physiological balance.

Aldosterone: The Electrolyte Balancer

Aldosterone, a mineralocorticoid produced by the zona glomerulosa, plays a critical role in regulating the body’s electrolyte balance and blood pressure.

Aldosterone’s Impact on Sodium and Potassium

How does aldosterone affect the body’s electrolyte balance? Aldosterone primarily acts on the kidneys to:

• Increase sodium reabsorption in the distal tubules and collecting ducts
• Promote potassium and hydrogen ion excretion
• Indirectly increase water retention, thus influencing blood volume and pressure

By maintaining the delicate balance of sodium and potassium, aldosterone helps regulate blood pressure and ensures proper cellular function throughout the body.

Adrenal Androgens: The Precursors to Sex Hormones

The zona reticularis of the adrenal cortex produces small amounts of androgens, which serve as precursors to both male and female sex hormones.

DHEA and Androstenedione

The primary androgens produced by the adrenal glands are:

• Dehydroepiandrosterone (DHEA)
• Androstenedione

These weak androgens can be converted to more potent sex hormones like testosterone and estrogen in peripheral tissues.

The Role of Adrenal Androgens in Development

How do adrenal androgens influence sexual development? Adrenal androgens contribute to:

• The onset of puberty
• The development of secondary sexual characteristics
• Maintaining bone density and muscle mass
• Supporting cognitive function and mood regulation

While the adrenal glands produce relatively small amounts of sex hormones compared to the gonads, their contribution is significant, especially during specific life stages such as adrenarche and menopause.

Catecholamines: The Fight-or-Flight Hormones

The adrenal medulla produces catecholamines, primarily epinephrine (adrenaline) and norepinephrine (noradrenaline). These hormones are crucial for the body’s immediate response to stress and danger.

Epinephrine: The Immediate Stress Responder

How does epinephrine prepare the body for action? When released, epinephrine:

• Increases heart rate and cardiac output
• Dilates airways to improve oxygen intake
• Redirects blood flow to essential organs and muscles
• Raises blood glucose levels for immediate energy

These rapid physiological changes enable the body to respond quickly to perceived threats or challenges.

Norepinephrine: The Blood Pressure Regulator

Norepinephrine works in concert with epinephrine but has some distinct effects:

• Constricts blood vessels to increase blood pressure
• Maintains alertness and arousal
• Modulates mood and cognitive function

The balance between epinephrine and norepinephrine helps fine-tune the body’s stress response to meet specific situational demands.

The Interplay of Adrenal Hormones in Health and Disease

The complex interactions between adrenal hormones influence numerous physiological processes and can contribute to various health conditions when imbalanced.

Adrenal Insufficiency and Cushing’s Syndrome

What happens when adrenal hormone production is disrupted? Two primary disorders can occur:

• Adrenal insufficiency (Addison’s disease): Characterized by inadequate production of cortisol and aldosterone
• Cushing’s syndrome: Results from excessive cortisol production or prolonged exposure to glucocorticoids

Both conditions can have significant impacts on metabolism, electrolyte balance, and overall health, underscoring the importance of maintaining proper adrenal function.

Adrenal Hormones and Cardiovascular Health

The adrenal glands play a crucial role in cardiovascular regulation through multiple mechanisms:

• Aldosterone’s influence on blood volume and pressure
• Cortisol’s effects on vascular reactivity and glucose metabolism
• Catecholamines’ acute regulation of heart rate and blood pressure

Imbalances in these hormones can contribute to hypertension, heart disease, and metabolic disorders.

Adrenal Hormones and the Immune System

The relationship between adrenal hormones and the immune system is complex and bidirectional. Cortisol, in particular, plays a significant role in modulating immune function.

Cortisol’s Immunomodulatory Effects

How does cortisol influence the immune system? Cortisol acts to:

• Suppress inflammation by inhibiting pro-inflammatory cytokine production
• Reduce the proliferation and activity of T-lymphocytes
• Decrease the production of antibodies by B-lymphocytes
• Promote the resolution of immune responses to prevent overactivation

While these effects are crucial for preventing excessive immune reactions, prolonged elevation of cortisol can lead to immunosuppression, increasing susceptibility to infections and certain autoimmune conditions.

The Stress-Immune Connection

The intricate relationship between stress, adrenal hormones, and immune function has led to the field of psychoneuroimmunology. Chronic stress can dysregulate the HPA axis, leading to altered cortisol production and subsequent effects on immune function.

Research has shown that stress-induced changes in adrenal hormone levels can influence:

• Wound healing rates
• Susceptibility to viral infections
• The progression of chronic inflammatory conditions
• The efficacy of vaccinations

Understanding these connections provides insights into potential therapeutic approaches for managing stress-related health issues and improving overall immune function.

Adrenal Hormones in Aging and Longevity

As the body ages, changes in adrenal hormone production and responsiveness can have significant impacts on health and longevity.

Age-Related Changes in Adrenal Function

How do adrenal hormones change with age? Several key alterations occur:

• Decreased production of DHEA and other adrenal androgens
• Alterations in the circadian rhythm of cortisol secretion
• Reduced responsiveness to stress-induced hormone release
• Changes in tissue sensitivity to adrenal hormones

These age-related changes can contribute to various aspects of the aging process, including decreased muscle mass, altered cognitive function, and increased susceptibility to stress-related disorders.

The Potential of Hormone Replacement Therapy

Given the decline in certain adrenal hormones with age, some researchers have explored the potential benefits of hormone replacement therapy, particularly with DHEA. While results have been mixed, some studies suggest potential benefits in:

• Improving bone density
• Enhancing cognitive function
• Supporting mood and well-being
• Maintaining muscle mass and strength

However, the long-term safety and efficacy of such interventions remain subjects of ongoing research and debate within the medical community.

Adrenal Hormones and Metabolic Health

The intricate interplay between adrenal hormones and metabolism underscores their critical role in maintaining overall health and energy balance.

Cortisol and Glucose Metabolism

How does cortisol influence blood sugar levels? Cortisol acts to:

• Stimulate gluconeogenesis in the liver, increasing glucose production
• Enhance insulin resistance in peripheral tissues
• Promote the breakdown of proteins and lipids for energy
• Counteract the effects of insulin, raising blood glucose levels

While these actions are adaptive during acute stress, chronic elevation of cortisol can contribute to insulin resistance and the development of type 2 diabetes.

Adrenal Hormones and Obesity

The relationship between adrenal hormones and obesity is complex and multifaceted:

• Cortisol promotes fat deposition, particularly in the abdominal area
• Chronic stress and elevated cortisol can increase appetite and cravings for high-calorie foods
• Alterations in the HPA axis can affect metabolism and energy expenditure
• Obesity itself can lead to changes in adrenal hormone production and sensitivity

Understanding these connections provides insights into potential therapeutic approaches for managing obesity and related metabolic disorders.

The Future of Adrenal Hormone Research

As our understanding of adrenal hormones continues to evolve, new avenues for research and potential therapeutic interventions are emerging.

Personalized Medicine and Adrenal Function

Advances in genetic testing and biomarker analysis are paving the way for more personalized approaches to managing adrenal disorders. Future developments may include:

• Tailored hormone replacement therapies based on individual genetic profiles
• Targeted interventions to modulate specific aspects of the HPA axis
• Novel drugs that mimic or enhance the beneficial effects of adrenal hormones while minimizing side effects
• Improved diagnostic tools for early detection of adrenal imbalances

These advancements hold promise for more effective management of adrenal-related disorders and improved overall health outcomes.

Integrative Approaches to Adrenal Health

Recognizing the interconnectedness of adrenal function with various bodily systems, researchers are exploring integrative approaches to optimizing adrenal health. These may include:

• Lifestyle interventions targeting stress reduction and sleep quality
• Nutritional strategies to support adrenal function and hormone balance
• Mind-body practices that influence the HPA axis and stress response
• Environmental modifications to reduce exposure to endocrine-disrupting chemicals

By addressing adrenal health from a holistic perspective, these approaches aim to enhance overall well-being and resilience to stress-related disorders.

The complex world of adrenal hormones continues to fascinate researchers and clinicians alike. As we unravel the intricate mechanisms by which these powerful chemical messengers influence our health, we open new doors to understanding and treating a wide range of physiological and psychological conditions. From metabolism and immune function to stress response and aging, the adrenal glands play a central role in maintaining the delicate balance of our internal environment. By harnessing this knowledge, we can develop more targeted and effective strategies for promoting health, managing disease, and improving quality of life across the lifespan.

   Adrenal gland hormones

Diagram of inside an adrenal gland

The adrenal cortex produces several hormones. The most important are aldosterone (a mineralocorticoid), cortisol (a glucocorticoid), and androgens and estrogen (sex hormones).

Aldosterone helps the kidneys control the amount of salt in the blood and tissues of the body.

Cortisol helps the body manage and use carbohydrates, protein and fat. It also causes changes in metabolism to help the body manage stress, and it suppresses the immune system.

Androgens are male sex hormones. The adrenal glands of both men and women make androgens, but in different amounts. Androgens help the organs of the reproductive system grow, develop and function. Androgens also control the development of male physical traits, such as deep voice, body and facial hair growth and body shape. Androgens are needed to make estrogen.

Estrogen is a female sex hormone. It controls female reproduction and sexual development, including the development of female characteristics such as the growth of breasts.

The adrenal cortex is made up of inner, middle and outer layers. Aldosterone is produced in the outer layer. Cortisol, androgen and estrogen are produced in the inner layer (active zone) and stored in the middle layer (storage zone). In times of stress, the storage zone shrinks and the active zone thickens to secrete more hormones.

The hormones produced by the adrenal medulla are called catecholamines. They act as hormones and as neurotransmitters (chemical messengers in the nervous system). They manage the body’s response to stress. The 2 more important catecholamines are epinephrine and norepinephrine.

Epinephrine (adrenaline) is released during times of short-term stress such as sudden shock or fear. It increases heart rate, blood pressure and blood sugar levels.

Norepinephrine (noradrenaline) constricts blood vessels. Like epinephrine, it increases heart rate, blood pressure and blood sugar levels.

The adrenal medulla also produces the protein chromogranin A, which is stored and secreted with epinephrine and norepinephrine.

Steroid Hormone Implants Used for Growth in Food-Producing Animals

Español

Since the 1950s, the Food and Drug Administration (FDA) has approved a number of steroid hormone drugs for use in beef cattle and sheep, including natural estrogen, progesterone, testosterone, and their synthetic versions. These drugs increase the animals’ growth rate and the efficiency by which they convert the feed they eat into meat.

All approved steroid implant products have a zero day withdrawal. This means that the meat from the animal is safe for humans to eat at any time after the animal is treated. Unless otherwise approved and labeled for reimplantation, only one ear implant may be given to an animal during a specific stage of growth. No steroid hormone implants are approved for growth purposes in dairy cows, veal calves, pigs, or poultry. All of the steroid hormone implants are available for over-the-counter purchase in the U.S. and are generally given by the livestock producer at specific stages of the animals’ growth.

The FDA approves these drugs only after information and/or studies have shown that the food from the treated animals is safe for people to eat, and that the drugs do not harm the treated animal or the environment. The drugs also have to be effective, meaning that they work as intended. The labeling for each product provides all instructions for safe and effective use and is approved by FDA. For each approved product, the FDA also makes available to the public via its website a Freedom of Information Summary that summarizes the information that FDA used to determine that the drug is safe for the treated animals, the animal products (edible tissues such as meat) are safe for humans to eat, and that the product is effective.

These steroid hormone drugs are typically formulated as pellets or “implants” that are placed under the skin on the back side of the animal’s ear. The implants dissolve slowly under the skin and do not require removal. The ears of the treated animals are discarded at slaughter and are not used for human food. Using scientific data, FDA establishes the acceptable safe limits for hormones in meat. A safe level for human consumption is a level of drug in the meat that would be expected to have no harmful effect in humans based on extensive scientific study and review.

Naturally-Occurring Hormones

Some of the approved drugs are naturally produced throughout life in people and animals, such as estradiol (estrogen), progesterone, and testosterone. These natural hormones are necessary for normal development, growth, and reproduction. People are not at risk from eating food from animals treated with these drugs because the amount of additional hormone following drug treatment is very small compared with the amount of natural hormones that are normally found in the meat of untreated animals and that are naturally produced in the human body.

Synthetic Hormones

Some of the approved drugs are synthetic versions of the natural hormones, such as trenbolone acetate and zeranol. Just like the natural hormone implants, before FDA approved these drugs, FDA required information and/or toxicological testing in laboratory animals to determine safe levels in the animal products that we eat (edible tissues). Furthermore, FDA required that the manufacturers demonstrate that the amount of hormone left in each edible tissue after treatment is below the appropriate safe level. As described above, a safe level is a level which would be expected to have no harmful effect in humans.

Additional Information

Information about approved hormonal implant products can be found in the Code of Federal Regulations (CFR), Title 21, Parts 522 and 556. Paper copies of the CFR may be found at your local public or university library and are for sale from the Superintendent of Documents, U.S. Government Printing Office, Washington, DC 20402. In addition, the Electronic Code of Federal Regulations may be found on the Internet: https://www.ecfr.gov/.

Find out how to properly treat thyroid hormones: what doses to choose and how to take the drugs correctly. Important features of therapy of the thyroid gland and its hormones.

The thyroid gland is one of the most important organs of the human body. It is responsible for the production of hormones that regulate metabolism, body temperature and many other important processes. However, in some diseases, the gland can stop functioning properly, which can lead to serious consequences.

One of the ways to treat such diseases is to take thyroid hormones. This approach allows you to remove the deficiency of hormones in the body and return the patient to normal health. However, it is important to understand that proper hormone treatment must be carried out according to strict rules and dosages, otherwise it can lead to negative health consequences.

In this article, we will look at the basic rules for taking thyroid hormones and talk in detail about which doses are suitable for different categories of patients. We will also answer the most frequently asked questions on this topic and consider the possible side effects of hormone treatment. So, let’s begin!

Treatment of thyroid disorders with hormones

Doses and rules for taking drugs

The thyroid gland is one of the most important organs of the endocrine system and a real problem when its functioning is disturbed. Treatment with thyroid hormones is often used when the levels of hormones produced by the thyroid gland are disturbed.

For effective treatment with thyroid hormones, it is necessary to follow the rules for taking the drugs. Hormones should be taken strictly in accordance with the doctor’s prescriptions. The recommended time of admission is in the morning, half an hour before the first meal, with enough water.

It is important to remember that treatment with thyroid hormones requires medical supervision. Failure to comply with the dosage or schedule of intake can lead to a deterioration in the condition of the thyroid gland and the general health of the patient.

To avoid side effects, it is recommended that you do not change your dosage or regimen without your doctor’s permission. If unusual symptoms appear, you need to inform the specialist about it and undergo regular examinations.

Absolute adherence to the doctor’s recommendations will help to achieve the effectiveness of treatment with thyroid hormones and prevent possible complications of the disease.

The thyroid gland and its important hormones

The thyroid gland is an organ of the human endocrine system located in the neck and produces hormones that regulate metabolic processes in the body. It plays a key role in maintaining body homeostasis.

Thyroid hormones are thyroid hormones such as thyroxine (T4) and triiodothyronine (T3), which are synthesized from iodine and tyrosine. They regulate metabolism, participate in the processes of growth and development of the body, and also control the functioning of many organs and systems.

Thyroxine (T4) is the main thyroid hormone produced under the control of the pituitary gland. It is responsible for the overall level of metabolism in the body, accelerates the growth and development of tissues, increases oxygen consumption, improves the functioning of the heart, brain and nervous system.

Triiodothyronine (T3) is a more active form of the hormone that is produced from thyroxine in body tissues. It is also involved in the control of metabolic processes, contributes to the production of heat and regulates breathing.

Who needs thyroid hormone treatment?

The thyroid gland is a glandular organ located on the front of the neck. Its function is to produce hormones that are involved in regulating the body’s metabolism.

If the thyroid gland is too active and produces too many hormones, this can lead to the development of hyperthyroidism, which is characterized by nervous excitement, high blood pressure, palpitations and other symptoms.

Also, some diseases can lead to disorders of the thyroid gland. In the presence of such diseases, treatment with thyroid hormones may be required.

What medications are used to treat thyroid hormone disorders?

Synthetic thyroid hormones such as Levothyroxine are often used to treat hypothyroidism (low thyroid function). This drug is able to increase the level of thyroid hormones in the body, which allows you to compensate for the deficiency of the thyroid gland. The dosage of the drug should be individually selected depending on the age, weight, general condition of the patient and the severity of the disease.

Hyperthyroidism (overactive thyroid gland) is often treated with antithyroid medications, drugs that help lower the levels of thyroid hormones in the body. One of the well-known drugs is Tyrozol. In turn, in the absence of a sufficient effect of thyreostatics, treatment can be supplemented with the use of radioactive iodine. The dosage of any drugs should be determined by a specialist, based on the general condition of the patient and the severity of the disease.

In addition, for a number of other thyroid disorders, other drugs may be used, the appointment of which depends on the diagnosis and characteristics of the patient’s body. Patients are prescribed individual dosages of drugs, as well as a specific regimen.

How to choose the right dose of hormones?

Several factors are important to consider when choosing a dose of thyroid hormones. First of all, the doctor focuses on the level of pituitary thyroid stimulating hormone (TSH) in the patient’s blood. It may indicate the need to increase or decrease the dose of medication.

It is important not to change the dosage of your medications yourself and follow your doctor’s instructions. The dose of hormones can be changed only after consulting an endocrinologist and conducting the necessary tests.

It is also worth remembering that patients with different thyroid diseases may be prescribed different dosages of drugs. For example, in hypothyroidism caused by surgical removal of the thyroid gland, a higher dose of hormones may be prescribed than in hypothyroidism caused by diffuse toxic goiter.

In general, the choice of the correct dose of hormones is carried out only by a doctor and requires an individual approach to each patient.

When should thyroid hormone treatment be started?

If a patient is diagnosed with hypothyroidism, thyroid hormone treatment should be started immediately. Treatment is prescribed individually, depending on the degree of dysfunction of the thyroid gland and the general condition of the patient.

To prevent possible complications, such as the occurrence of thyrotoxicosis or oncological diseases, it is necessary to regularly monitor the level of thyroid hormones and, if necessary, adjust the dosage of drugs.

Before you start taking thyroid hormones, you must undergo a complete medical examination, including testing for the level of thyroid hormones in the blood. You should not start treatment on your own, without a doctor’s prescription, as the wrong dosage can lead to negative health consequences.

Rules for Taking Thyroid Hormones

Correct Time to Take

Thyroid hormone preparations should be taken in the morning on an empty stomach, 30-60 minutes before meals. This will allow better absorption of the active substance and ensure a sufficient level of blood hormones.

Dose compliance

The dosage of thyroid hormone is prescribed individually depending on the patient’s condition and hormonal profile. For the treatment of hypothyroidism in adults, it is usually recommended to start with low doses and increase gradually. Significant changes in dosage can be hazardous to health, so only a doctor can adjust it.

Consistent supply

Make sure you are taking the same brand of hormones you are prescribed. Several brands are bioequivalent, but may be slightly different in their activity, which may compromise the consistency of the treatment.

Don’t skip doses

If you miss a dose, take it as soon as possible, but don’t double your dose. If you notice that you have missed a dose of thyroid hormone, contact your doctor.

• Stick to the rules of taking
• Do not change the dosage without consulting a doctor
• Choose only one brand of drug
• Do not skip doses or take a double dose

What side effects can occur with thyroid hormone treatment?

Side effects of drugs containing thyroid hormones depend on their dosage and duration of use.

1. With an increased dosage, heart failure, arrhythmias, pain in the heart, and increased blood pressure may occur.
2. Some people may experience headaches, anxiety, irritability, insomnia, tremors.
3. Patients may experience frequent urination, abdominal pain, diarrhea, nausea, vomiting, increased appetite.
4. Long periods of hormonal intake can lead to a decrease in calcium stores, which can lead to osteoporosis.
5. In women, menstrual irregularities, reduced lactation during breastfeeding are possible.

If side effects occur, you should consult a doctor to select a more optimal dose of thyroid hormones.

How long should I take thyroid hormones?

Duration of treatment hormonal preparations depends on many factors, such as the cause of thyroid dysfunction, hormone levels, age and general condition of the patient. Typically, the treatment course lasts at least 6 months, but can last for several years.

If the patient is taking hormonal drugs after thyroid surgery, the duration of the drugs can vary considerably, as well as the doses. Some patients will need to take hormones throughout their lives.

Important! Do not change the dosage or duration of treatment without first consulting a doctor, as this can lead to serious consequences and aggravate the patient’s condition.

When normal levels of hormones in the blood are reached and the symptoms of the disease disappear, the doctor may decide to reduce the dose of the drug or stop it completely. However, even after stopping the drugs, patients will follow the doctor’s recommendations and undergo regular medical examinations to make sure there are no recurrences of the disease.

Alternative thyroid treatments

In addition to hormone treatment, there are alternative treatments called homeopathy, herbal medicine and acupuncture.

Phytotherapy is a treatment method that uses herbs and plant extracts. Some herbs can help improve thyroid function, such as ginseng, mint, kelp, and others.

Acupuncture is a treatment method based on the impact of needles on certain points on the body. This treatment can help improve circulation and reduce inflammation in the thyroid gland.

• It is important to remember that alternative therapies will not replace full hormone treatment, but may help reduce symptoms.
• Consult a specialist before starting alternative treatments.

Conditions requiring a change in the dose of thyroid hormones

The appearance or disappearance of symptoms of the disease . When treating with thyroid hormones, it is necessary to regularly monitor the symptoms of the disease. If there are changes in the patient’s health, this may require a change in the dose of hormones.

Laboratory results . Treatment with thyroid hormones requires careful monitoring of blood hormone levels. If the results of laboratory tests show abnormalities, this may mean that the dose of hormones needs to be adjusted.

Frequency of medications . For effective treatment with thyroid hormones, it is important to follow the regimen of medication. If the patient is not on a regular schedule or does not take drugs regularly, this may require a change in dosage.

Patient characteristics . Each patient is unique and the body’s response to hormone treatment may vary. If the patient experiences side effects from drugs or has other body characteristics, this may require a decrease or increase in dosage.

Pregnancy or lactation period . In women during pregnancy or lactation, dose adjustment of thyroid hormones may be required. During this period, women often experience changes in hormone levels, and their condition and dosage of drugs must be carefully monitored.

How to control hormone levels during treatment?

1. Regular blood tests

Regular blood tests are essential to control hormone levels during treatment. At the same time, the doctor can prescribe one or several types of tests, such as total thyroid hormone, free thyroxine and triiodothyronine, thyroid stimulating hormone, etc.

drugs prescribed by a doctor. In this case, the drugs should be taken every day at the same time and in given doses.

3. Avoiding self-medication and changing the dose without consulting a doctor

Do not independently change the dose of the drug during treatment with thyroid hormones without consulting a doctor. In case of any changes in the medications taken, it is important to discuss this with the doctor who is present at the consultation.

4. Avoiding sudden changes in diet

During treatment with thyroid hormones, it is important to avoid sudden changes in diet, as this may affect the level of hormones in the body. If you plan to change your diet, you should discuss this with your doctor.

5. Visiting a doctor in case of dosage irregularities or side effects

If there are irregularities in the dosage of drugs or unwanted side effects, you should immediately consult a doctor. Improper use of drugs can lead to negative consequences and poor health.

Q&A:

What medications are used to treat thyroid hormones?

Levothyroxine, liothyronine, thyreocombin and others are used to treat thyroid hormones.

What are the rules for taking thyroid medications?

Thyroid medications are taken in the morning on an empty stomach, 30-60 minutes before meals. It is not recommended to use them simultaneously with other drugs and products that affect the absorption of medicinal substances. The dosage and mode of administration is prescribed by the doctor, depending on the condition of the thyroid gland and other factors.

How long should I take thyroid medication?

The duration of treatment with thyroid hormones depends on the severity of the disease, the type of drug, usually treatment is carried out for many years and often for life.

What are the symptoms of an overdose of thyroid hormones?

Symptoms of thyroid overdose may include tachycardia, increased appetite, sweating, nervousness, anxiety, especially in elderly patients. At elevated doses of L-thyroxine, blood flow may be impaired by narrowing blood vessels or enhancing the effect of the drug on the heart.

What are the causes of enlargement or reduction of the thyroid gland?

Enlargement of the thyroid gland can be caused by dietary iodine deficiency, hormonal changes, inflammation and swelling of the thyroid gland. A decrease in the size of the thyroid gland can be caused by a decrease in the function of the gland, surgical removal, radiation, or other factors.

What precautions should be taken when taking thyroid hormones?

Before starting treatment with thyroid hormones, it is necessary to consult a doctor, tell about all health problems and medications used. You should not independently change the dosage or regimen of taking medications. It is also necessary to monitor your condition and undergo regular examinations.

Thyroid hormones. Clinic of the Thyroid Gland of Dr. A. V. Ushakov – official site.

The function of the thyroid gland is not limited to the production and release of hormones, since all endocrine glands do this. In other words, the formation of hormones is a general function of the endocrine glands, but each gland performs its own specific functional tasks in the body with these hormones. Therefore, the function of each endocrine gland is the function of its hormones.

Calcium metabolism and thyroid gland

Calcitonin is produced by special calcitonin cells, which are much less than the cells that produce T4 and T3. Due to the fact that the word “calcium” in Latin begins with the letter C (Calcium), these cells are called C-cells in Russian. Together with parathyroid hormone, calcitonin is involved in the regulation of calcium and phosphorus metabolism.

Analysis of calcitonin in the blood is appropriate to study in the pathology of the parathyroid glands. For example, parathyroid adenoma. The blood test in this case should always include the determination of ionized calcium. Usually, with a normal concentration of calcium in the blood in the case of parathyroid adenoma, no surgical measures should be taken. But regular (annual) control of this type of exchange is required.

Energy hormones of the thyroid gland – T4 and T3

Energy metabolism , in which the thyroid gland is involved, is commonly called the main metabolism of the body. Providing the energy that we get from food (from fats and carbohydrates) is impossible without thyroid hormones – T4 and T3, which allow us to absorb energy substances from fats and carbohydrates.

Abbreviated names of calorigenic thyroid hormones are convenient. They contain the Latin name of the thyroid gland itself (Thyroid) and the number of iodine atoms in the hormone molecule. That is, T4 (thyroxine) contains 4 iodine atoms, and T3 (triiodothyronine) contains 3 iodine atoms.

The thyroid gland produces and releases into the blood more than T4 (about 80-90%) and, accordingly, less than T3 – 10-20% . In this ratio, there is an important feature of the energy metabolism of thyroid hormones and, in fact, the function of thyroid hormones.

Hormone T4 is less active compared to T3 by 7-10 times , according to different authors. The nature of the body is designed to produce more of the T4 hormone, which releases less energy, and, as needed, to create the T3 hormone, the body’s main hormone consumed, from T4.

The thyroid gland secretes T4 into the blood, which enters various organs and tissues with the blood flow, where it is converted into T3 by the deiodinase enzyme due to the detachment of one iodine atom, which again returns to the blood and can be used to produce hormones. As a result, almost all of the T4 is gradually converted to T3 by deiodination. Therefore, T4 is the main hormone produced and T3 is the main hormone consumed . T4 is sometimes referred to as a prohormone or precursor hormone. Therefore, when analyzing blood, both hormonal indicators, T4 and T3 (free), should always be determined together with TSH.

Where does the conversion from T3 to T3 take place? In the liver, kidneys, intestines, muscles. brain, heart, etc. There are several types of deiodinase enzyme, which perform the main and additional tasks in different organs.

What else do you need to know? Selenium takes an important part in the formation of hormones within the thyroid gland and in the deiodination of T4 to T3 in other organs. Therefore, in some cases of hypothyroidism, it is important to help the body by using a physiological amount of selenium (with food or medicine), in accordance with the doctor’s prescription.

An important feature is the storage of hormones in the body. The produced hormones are stored in the follicles of the thyroid gland itself and in the blood, where they are combined with proteins. The connection of T4 and T3 with protein molecules in the blood refers to related fractions of these hormones. Such bound T4 and T3 are not used. But in case of need, proteins are able to detach thyroid hormones for use. Hormones that are not bound to proteins are called free . It is they who should be determined in a blood test.

Thyroid blood test

Analysis is the process of highlighting its elements in a single whole. Therefore, it is correct to say “donate blood for analysis”, and not “take a blood test”. Hormones are elements of the blood, but not “tests”. T3 and T4 are indicators determined by a blood test, because they show the concentration of the substances we need.

When conducting an analysis of the hormonal metabolism of the thyroid gland , the mandatory minimum are three indicators – TSH, T3f. and T4sv . The study of only TSH or two parameters is inadequate for clinical conclusion. Blood test only for TSH or TSH and T4F. are outdated and erroneous.

For a complete blood test “for the first time”, our Thyroid Clinic recommends to determine together (i.e. “not missing”) the following blood parameters: TG . If hyperthyroidism and thyrotoxicosis (Graves-Basedow’s disease) is known or suspected, it is important to determine AT-rTTG . In some cases, the evaluation of thyroglobulin blood is important. For nodules, the doctor may recommend a calcitonin test to rule out a very rare type of cancer – medullary, which is formed from C-cells.

The control of hormonal metabolism of the thyroid gland is individual for each case of the disease, the characteristics of the course and severity. On average, with hyperthyroidism, a control blood test is performed every 1-1.5 months, and with hypothyroidism – every 1.5-2 or more months.

Evaluation of blood test data

Patients refer to the interpretation of laboratory data as decoding. How to decipher the result of a hormonal blood test?

The study and evaluation of hormones and antibodies is not as simple as it might seem. However, the rules for decrypting data are not very complicated. It is only necessary to understand some features.

You should know what parts of the normal interval for TSH, T4 and T3 consist of and what the changes in the values ​​of these indicators relative to these parts within and outside the norm mean. For patients, the Thyroid Clinic offers a special guide – Book “Blood test for diseases of the thyroid gland” . In this book, all cases of hormonal metabolism are explained and shown in simple language, examples from real practice are shown with detailed comments.

Our Clinic has prepared special films for patients to master the essence of thyroid hormone metabolism. Therefore, we suggest obtaining knowledge from several sources.

How to donate blood for hormone analysis

You can usually donate blood for testing thyroid hormones, TSH, and antibodies at any time of the day. Regardless of the meal, the period of the menstrual cycle.

But there is a daily rhythm of TSH, a pituitary hormone that stimulates hormonal production of the thyroid gland. According to some studies, fluctuations in the concentration of TSH in the blood in most cases are insignificant and can rarely affect the assessment of hormonal metabolism.

To exclude the effect of the circadian rhythm in the metabolism of hormones, we recommend that you donate blood for analysis at the same time of the day.

Before visiting the laboratory, it is better not to take a hormonal or thyreostatic drug that can be used after visiting the laboratory. But this recommendation is not strict, because. usually significant fluctuations in the values ​​of blood parameters are not detected.
