The endocrine system of the human body is of great importance for its full functioning. TSH (thyroid stimulating hormone) is a special marker that indicates the presence of a pathological process in the thyroid gland, pituitary gland or hypothalamus. If external signs of deviation from normal values ​​are found, it is necessary to conduct a thorough examination and identify the reasons why the TSH hormone is elevated.

What is TTG

Thyroid stimulating hormone (TSH) is an active substance produced by the pituitary gland. The pituitary gland is a structure located in the brain. Thus, TSH is not a thyroid hormone, but it has a great effect on the thyroid. Its production is controlled by the central nervous system, and in particular by the hypothalamus.

TSH controls the production of thyroid hormones - T3 (triiodothyronine) and T4 (thyroxine).

T3 and T4 are necessary for the normal functioning of the cardiovascular, nervous, reproductive systems, as well as for ensuring a full-fledged metabolism and the production of vitamin A and protein (protein).

The functions that TSH performs in the body:

• Stimulation of the production of T3 and T4;
• Transportation of iodine to thyroid cells;
• Participates in the metabolic processes of the body and the synthesis of nutrients.

If the level of TSH increases significantly (more than normal), then the concentration of T3 and T4 decreases, and vice versa. This imbalance provokes the occurrence of pathological processes in the body.

The norm of thyroid-stimulating hormone

The concentration of thyroid-stimulating hormone changes with a person's age. The highest values ​​are recorded in small children, and the older a person becomes, the lower the TSH value.

Table of norms of thyroid-stimulating hormone depending on age:

The level of thyroid-stimulating hormone fluctuates throughout the day. So the greatest value is noted at night, between 2 and 4 hours. And the lowest rates are recorded in the evening hours, between 17 and 18.

You should also take into account such a physiological state in women as pregnancy. During this period, the indicators decrease somewhat, and in case of multiple pregnancy, they can reach zero.

The rate of thyroid-stimulating hormone in pregnant women depends on the gestational age - from 0.1 to 2.4 mU / l. In the first trimester, TSH values ​​​​have the lowest values. But in the third trimester, the maximum level of the hormone is noted.

The decrease in TSH levels during pregnancy is due to increased blood circulation in the thyroid gland, which in turn leads to increased production of its hormones. And if the concentration of T3 and T4 increases, then, accordingly, the TSH indicators decrease.

The main causes of elevated TSH

An increase in TSH can occur due to a pathological process in the thyroid gland or the pituitary gland.

The main reasons for the increase in thyroid-stimulating hormone:

• Thyroid damage. In this case, there is a lack of T4 (thyroxine). Etiological factors (causes) are:
  • Complete removal of the thyroid gland. Postoperative hypothyroidism develops, which requires medical correction;
  • Autoimmune thyroiditis is an inflammatory process that occurs in the tissues of the thyroid gland, which is caused by the extermination of organ cells by the person's own immune system;
  • Thyroid injury. If its tissues are damaged, a narrowing of the production of hormones is noted;
  • Benign and malignant neoplasms;
  • Radiation therapy.

• Pituitary lesion, that is, its work is disrupted, which leads to an increase in TSH production:
  • Malignant neoplasms of the pituitary gland and surrounding tissues of the brain;
  • Benign tumors of the pituitary gland;
  • Hyperprolactinemia is a condition in which levels of the hormone prolactin are significantly elevated. It may be associated with the presence of tumors in the pituitary gland.
• Lack of iodine in the human body - the most innocuous reason for the increase in TSH.

It should also be noted separately that there are such human conditions that can lead to an increase in the concentration of the TSH hormone.

In the following situations, thyroid-stimulating hormone may also be elevated:

Why does the rate increase during pregnancy

As noted above, in pregnant women in the first trimester, the level of TSH is normally reduced, but with an increase in the term, its indicators begin to rise. This is not considered a pathology, since after 18 weeks of pregnancy the thyroid gland begins to function in the fetus and the mother's hormones (T4 and T3) are no longer needed. This is the physiological reason for the change in thyrotropin levels.

Causes of an increase in the TSH hormone in early pregnancy:

• Hypothyroidism- Decreased thyroid function. Pregnancy is a big burden on a woman's body. All organs and systems work to the limit. In some cases, the thyroid gland cannot cope with the new conditions, that is, it cannot produce enough of its own hormones to provide the body of the woman and the fetus with them. In this case, the pituitary gland begins to produce more thyroid-stimulating hormone to boost the production of T3 and T4;
• The presence of pituitary tumors;
• Severe toxicosis, gestosis, which is accompanied by massive edema, the appearance of protein in the urine and an increase in blood pressure;
• The presence of chronic diseases of the cardiovascular, respiratory and nervous systems;
• Depression and severe stress also cause an increase in the hormone;
• The presence of bad habits (smoking);
• Taking certain groups of drugs (for example, iodine-containing);
• Body intoxication due to poisoning with heavy metals (mercury, lead, zinc) is also the cause of an increase in the content of the hormone;
• Physical activity in large volume. They further weaken the body of a pregnant woman, which is already working at its limit.

Symptoms of high hormone levels

At first, after an increase in the concentration of thyroid-stimulating hormone in the blood, there are no pathological symptoms.

Characteristic signs of an increased content of the hormone:

• Violation of the nervous system. This is manifested by the following symptoms:
  • Depressive state;
  • Decreased memory;
  • The patient complains of a constant feeling of fatigue, drowsiness;
  • Apathy.
• Problems in the reproductive system. In women, there is a violation of the menstrual cycle according to the type of oligomenorrhea (reduction in the volume of menstruation) and amenorrhea (complete absence of menstruation), infertility develops. In men, there is a decrease in libido, impotence;
• There is an increase in body weight against the background of reduced appetite. These patients are characterized by the development of obesity;
• constipation;
• Hypotension- lowering blood pressure;
• Hypothermia- body temperature is reduced;

• puffiness. Moreover, swelling is localized on the face, and more precisely in the eye area;
• The skin is dry, cracks form on them;
• Nails become brittle;
• Hair falls out in large quantities;
• Swelling or inflammation in the thyroid gland. In this case, the following symptoms are observed:
  • Enlargement and / or deformation of the neck;
  • Speech becomes slow;
  • Change in skin color on the neck. It becomes red or bluish;
  • Discomfort when swallowing (lump in throat);
  • Pain in the region of the thyroid gland.

Treatment Methods

If an elevated level of thyroid-stimulating hormone is detected, it is necessary to contact an endocrinologist and undergo a full examination to find out the reasons for the increase in the indicator - it should be remembered that only a specialist prescribes treatment. Self-medication in this case is dangerous. It can cause great harm to health.

Against the background of an increased level of TSH in the body, various diseases of the internal organs occur, which require immediate treatment.

If we are talking about a subclinical form of hypothyroidism (clinical manifestations are absent, only changes in the blood are observed), then treatment with hormonal drugs is not carried out. Patients are under the supervision of an endocrinologist, the level of hormones in the blood is monitored.

Treatment for subclinical hypothyroidism includes:

• Diet
• The use of vitamin complexes and minerals according to indications;
• Exclusion of stress. The use of sedatives based on medicinal plants: valerian, motherwort.

If hypothyroidism is observed in a pregnant woman, then hormone treatment is carried out in any case, regardless of the form of the pathology.

With manifesto hypothyroidism (detailed clinical picture), treatment is carried out with the help of synthetic thyroid hormones. Most often prescribed: Euthyroxy and L-thyroxine.

First, the minimum dosage of the drug is prescribed. A month later, it is carried out to control the ongoing therapy. Based on the results of which, the doctor decides whether to change the dosage or continue the ongoing treatment. Most often, patients require lifelong use of synthetic hormones.

If the increase in the amount of this hormone occurred against the background of iodine deficiency, then iodine-containing drugs are prescribed.

In severe cases, surgical treatment is performed: excision of a lobe or complete removal of the thyroid gland.

diet therapy

The diet is prescribed for hypothyroidism. It is aimed at improving metabolism and oxidative processes in tissues. It is recommended to reduce the consumption of carbohydrates and fats.

Foods to avoid with hypothyroidism:

• Fatty meats and fish;
• Fatty dairy products: cream, butter, sour cream;
• Caviar red and black;
• Confectionery;
• Sweet pastries;
• Honey and jam;
• Sweet fruits;

• Margarine, mayonnaise;
• Wheat flour;
• White polished rice;
• Salt in large quantities, canned foods;
• Reduce the amount of fluid you drink.

Foods that can be eaten by patients with hypothyroidism:

Methods of cooking: stewing, boiling and baking. Fried foods should be completely avoided. Food should be fractional, 4 - 6 times a day.

Complications and consequences

If a change in the hormonal background is detected on time and appropriate treatment is carried out, then the prognosis is favorable. A person lives a normal life, his performance is not disturbed.

Signs of hypothyroid coma:

• A sharp decrease in body temperature (up to 35 degrees);
• The skin becomes cold and pale;
• Severe weakness;
• The pulse becomes rare (bradycardia);
• A sharp decrease in blood pressure;
• hypoglycemia;
• Loss of consciousness;
• Inhibition of all reflexes.

In the absence of treatment for elevated TSH, a life-threatening complication develops - hypothyroid coma. This condition can lead to the death of the patient due to the development of cardiovascular and respiratory failure.

Complications during pregnancy:

• early miscarriage;
• Preeclampsia (late toxicosis), which occurs in the third trimester of pregnancy;
• Premature placental abruption;
• The development of pathologies in the fetus;
• Retardation of intrauterine development of the fetus.

All these complications can be avoided with the timely correction of hormone levels.

If thyroid-stimulating hormone is elevated in a woman's body, then this can mean a number of serious problems. After all, thyroid-stimulating hormone controls the activity of the thyroid gland, and it, in turn, produces such important hormones for the female body as T3 and T4. Therefore, if the thyroid-stimulating hormone is above the norm, then a variety of systems and organs of a person can be upset - cardiovascular, sexual, gastrointestinal, and we must also not forget that an increased level of TSH disrupts metabolism.

High TSH is very difficult to diagnose, since its level changes significantly during the day, and as for the female body, an increase in thyroid-stimulating hormone or a decrease in it accompanies the monthly menstrual cycle.

TSH is produced in the pituitary gland from there it enters the bloodstream and with the bloodstream already penetrates to the sensors of the thyroid gland. An increase in TSH has a number of quite recognizable symptoms.

1. Increased TSH in women primarily manifests itself on the face - it noticeably swells due to water accumulated between soft tissue cells.
2. A high level of TSH affects the condition of the skin. It becomes thin, pale and covered with small cracks.
3. Symptoms of elevated TSH also appear in a woman's hair. They lose their luster, become thin and brittle. They split at the ends and fall out in a much larger volume than usual.
4. Signs that the TSH hormone is elevated are manifested not only in the appearance of a woman. She quickly gets tired, during the day she is haunted by weakness and malaise.
5. The psyche is broken. The woman becomes irritable and nervous. The mood changes dramatically several times a day, from unreasonable aggression to complete apathy.
6. If TSH is higher than normal, then the central nervous system also suffers. The brain of a woman works slowly, which is manifested in constant thoughtfulness and inability to think logically and rationally.
7. Elevated thyrotropin causes disruptions in the digestive system. Constipation replaces diarrhea and vice versa. The woman is haunted by constant nausea.
8. When TSH is elevated, the level of T3 and T4 is disturbed, and the level of a hormone such as prolactin also changes. He is responsible for the functioning of the reproductive system, and in particular the uterus, prolactin suppresses its contractions, which is extremely important during pregnancy. In addition, prolactin helps produce milk in the postpartum period. And while prolactin is elevated, a woman cannot become pregnant again. If it is reduced, then she may incur even at the stage of breastfeeding the first child. This is not always good, since pregnancy is very exhausting for a woman's body. Thus, prolactin protects the body from too early pregnancy.

Causes of an increase in TSH in women

If TSH is elevated, what does this mean in women? There are several reasons for this.

1. Somatic or mental illness, and the form of pathology is extremely severe.
2. TSH at the upper limit of the norm may be due to pathologies of the adrenal glands.
3. Sometimes the causes and consequences are closely related to the past therapy. This happens after the removal of part of the thyroid gland by surgery.
4. Goiter of the thyroid gland, that is, a significant increase in the size of this organ.
5. Infectious disease of the genital or urinary system.
6. Tuberculosis, asthma, bronchitis and other diseases of the lungs and bronchi.
7. Ulcer of the stomach or duodenum.
8. The occurrence of a tumor in the reproductive or urinary system.
9. It happens that the thyroid gland chronically receives less iodine. This is caused by the ecological situation in which a person lives.
10. Often the treatment for elevated TSH is a consequence of hemodialysis - artificial washing of the kidneys.

A separate reason for the overestimated level of the trace element is the pregnancy of a woman. During this period of her life, all body functions change, the levels of various hormones not only change, but do so several times a day. For a baby developing in the womb, it is important that the thyroid-stimulating hormone does not exceed a value of 2 or 2.5 units. Then his thyroid gland will grow properly, and produce all the substances necessary for the growth of his body. For your information, the child's thyroid gland is formed and begins to work already in the first half of pregnancy, at 2.5-3 months.

Hyperprolactinemia and hypothyroidism are extremely dangerous phenomena during pregnancy. They develop in violation of the level of TSH and can lead to placental abruption with subsequent miscarriage. Or disorders leading to intrauterine pathologies. Often incompatible with the life of the baby.

Norms and rules for passing the analysis

A normal indicator of thyrotropin in a woman is 0.4-4.0 μU / l. The question arises - why the lower level of the norm is almost two times less than its upper level. This is due to the fact that the level of the microelement in the blood largely depends on the age, the woman, her lifestyle, and most importantly, on the day in the monthly cycle.

Therefore, in order to adequately assess whether TSH is elevated or not, an analysis is usually taken for triiodothyronine - T3 and compared with thyroxine - T4. Their overall level helps determine if TSH is elevated and what that means.

Moreover, in order to determine elevated TSH in women, there are a number of recommendations that must be followed before donating blood for analysis.

1. 2 days before the analysis, you can not engage in heavy physical work or sports.
2. 2-3 days before the procedure, you should stop taking steroid or hormonal drugs, such as contraceptives. If this is not possible for medical reasons, then the doctor receiving and analyzing the results of the studies should be warned about this.
3. 1 day before blood sampling, do not drink alcohol and smoke cigarettes.
4. For 10-12 hours, you should calm your nervous system. It is necessary to avoid stressful situations during this period.
5. A blood test is taken only on an empty stomach. That is, you can not eat food 8-10 hours before the procedure. You can only drink plain water. A blood test will be more accurate if you do not brush your teeth in the morning before going to the laboratory.

The interpretation of the analysis, taking into account all the individual characteristics of the patient, is handled by a gynecologist or endocrinologist. you won't be able to figure it out on your own. For this you need to have special knowledge.

Treatment for high TSH

When TSH is elevated in women, the conclusion is about the causes. Never put only on the results of the analysis. After all, if TSH has changed its level, then the reasons can be hidden in a variety of organs. Therefore, a woman undergoes a procedure for examining the kidneys and reproductive system using ultrasound, and the brain is checked in a tomograph. The doctor collects a complete history, with clarification of the lifestyle and diet of the patient. Therapy is prescribed only on an individual basis. Sometimes it can last until the end of a woman's life, for example, with hypothyroidism.

How to lower TSH in women, the endocrinologist and gynecologist may know, therefore, when the first symptoms of pathology appear, you should contact a specialist.

He will not only tell you what to do, but also prescribe the exact amount of the drug, as well as the scheme for taking it. Any violation of the dosage of these drugs can lead to serious consequences.

Treatment of high levels of TSH with folk remedies

It is clear that it is rarely possible to completely cure pathology and lower TSH with folk remedies, but this type of therapy is widely used as an auxiliary measure in treatment.

After all, if the reasons for the increase are not in the tumor, but in, for example, malnutrition or lifestyle, then the level indicator can be brought back to normal in this way.

And one more important fact - thyroid gland is extremely sensitive to various chemicals, and natural remedies, free growth, rarely complicate the situation. With the exception of individual allergies to a particular plant.

Here are some of the easiest ways to prepare a remedy.

1. If TSH is elevated, then birch leaves, licorice, celandine, angelica, coltsfoot, yarrow, rose hips will help. These ingredients are mixed in equal proportions and brewed with boiling water. Then the broth is put on a slow fire and boiled for another 1 hour. You can increase its effectiveness by closing the finished product in a thermos for 24 hours. After the broth has cooled, it can not be filtered. with increased TSH, it should be consumed in 50 grams. morning for 30 days. If the trace element level is very high, then the course leaves 90 days.
2. Dry fruits of juniper, yarrow and buckthorn bark should be brewed with boiling water and infused for 10 hours. After the product has cooled down, strain it and consume 10 gr. at bedtime for 30 days.
3. Chamomile, St. John's wort, dill, dandelion, wild rose, chicory. Mixed in one collection and brewed with boiling water for 30 minutes. If TSH is too high, then as a result of daily use of this decoction, it will decrease slightly, but will decrease after 4-5 days. If the hormone is highly elevated, then the course of treatment will be 30-45 days.

What does the presence of these recipes say? The fact that people faced hormonal problems at the dawn of centuries, when there was no modern medicine. And they tried to lower the level of TSH to normal, without even realizing what it was.

But centuries of experience have made it possible to choose the most effective means that can be trusted to this day. And this is not surprising, because the fact that the goiter is enlarged is visible to the naked eye.

An analysis of thyroid-stimulating hormone, or TSH, will help to identify a violation in the endocrine system at an early stage, or to clarify the situation if a particular disease is suspected. In order to obtain a reliable result, you need to know exactly the rules of preparation before sending for TSH analysis.

How to take it to a woman, what time of day, how to deal with food intake - a special instruction has been drawn up for these and other issues.

Under its influence, the thyroid gland produces its own hormones - T3, T4 and calcitonin. TSH is produced by the pituitary gland, which together with the hypothalamus decides how much hormone to release to maintain thyroid hormone levels.

With a lack of thyroid hormones in the blood, TSH is secreted by the pituitary gland in larger quantities. If there are enough hormones, then less TSH is secreted, since the need for it decreases.

In addition to directing the thyroid gland, TSH influences other processes of the human body on its own. The photos and videos in this article will show how TSH works in a woman's body.

Functional features of TSH

Thyroid-stimulating hormone increases the blood supply to the thyroid gland, as a result of this process, free iodine molecules from the blood are easily absorbed and absorbed, which provides the necessary content of triiodothyronine.

The TSH hormone performs many functions:

• stimulates the production of thyroid hormones (thyroxine, triiodothyronine);
• participates in the synthesis of proteins, carbohydrates, fats;
• normalizes the function of the heart and blood vessels;
• responsible for the work of the reproductive function;
• normalizes psychosomatic reactions.

TTG carries out its tasks in two directions:

1. directly proportional. When the level of TSH in the blood rises, the level of thyroid hormones (T3 and T4) also exceeds the norm. Symptoms of elevated TSH in women can mean several pathological conditions, including such good news as pregnancy.
2. Inversely proportional. When the thyroid gland, for some reason, began to produce thyroid hormones in large volumes, the pituitary gland receives a signal from the hypothalamus to reduce the synthesis of these hormones, therefore, the production of TSH decreases, and this in turn leads to a reduced productivity of thyroxine and triiodothyronine.

Interesting fact. Medical scientists have not yet found a single optimal value for the TSH norm, since its level in a person’s blood is constantly changing and depends on factors such as age and time of day.

Indications for analysis

The doctor prescribes an examination for TSH sensitive thyroid-stimulating hormone, the norm in women of which varies widely, in the presence or suspicion of the following pathologies:

1. Latent hypothyroidism.
2. Toxic goiter.
3. Amenorrhea.
4. endemic goiter.
5. thyrotoxicosis.
6. Nodules in the thyroid gland.
7. diffuse goiter.
8. An increase in the content of prolactin in the blood.
9. Frequent fluctuations in body temperature.
10. Neoplasms of the thyroid gland.
11. Disorder of the work of some muscle groups.

Interesting: In addition, an analysis for TSH can be prescribed: when planning a pregnancy, during childbearing, in the postpartum and postoperative periods, for the purpose of dynamic monitoring, as well as when correcting body weight.

Why is this analysis needed?

In modern medicine, it is customary not to start treatment until the situation is clarified by the results of the tests.

To prescribe treatment

First, the patient comes to the doctor with his complaints, the doctor performs an initial examination - palpation of the problem area, if any. The doctor prescribes tests that he considers necessary to confirm or refute his initial, alleged diagnosis.

Important: the most accurate picture is given by the simultaneous study of TSH and thyroid hormones.

Further, with the available analyzes, instrumental research methods can be added - radiography, if necessary. Only after identifying reliable signs of the presence of the disease, treatment will be prescribed.

Important: in any case, the clarification of the situation begins with laboratory tests, they are indispensable in all cases.

For prevention

There are situations when a woman has to take TSH without complaints of problems with the thyroid gland:

1. For some diseases of the vessels, heart and gynecological problems, an analysis for TSH is also required. After all, the spectrum of influence of thyroid-stimulating hormone is huge and is not limited to the thyroid gland.
2. If a person has a disease associated with an imbalance in the production of TSH, the analysis will have to be repeated at some intervals.
3. If a person has close relatives with endocrine diseases, it is necessary to undergo preventive examinations in order to catch the first signs of the onset of the disease and prevent its development.
4. If a woman is planning a pregnancy, you need to make sure that nothing will interfere with the development of the child.
5. In the case when a woman is already pregnant, then the analysis must be performed up to 12 weeks, since this is the most important stage in the growth of the baby, and during this period they must be present in the mother's blood in the required amount.

Rules for preparing for analysis

Important: blood sampling for this analysis is carried out only from a vein.

1. Donate blood in the morning. Between 8 am and 11 am. At this time, the concentration of thyroid-stimulating hormone is at its peak. If the patient is not able to donate blood in the morning, then when donating during the day, it is worth pausing in the meal - 6 hours.
2. Night fasting should be at least 8 hours, but not more than 12 hours of fasting. Eating later will cause hormonal changes.
3. One or two days before the analysis, you need to refrain from eating very fatty, very sweet and salty foods. At the same time, breakfast on the day of delivery should be light, it should not contain a large amount of fats and sugars. These substances require effort from the body for their digestion, which means they will affect the composition of the blood.
4. If the patient smokes, it is worth abstaining as long as possible, but not less than one hour before the delivery of the material. Nicotine has biological activity in relation to many hormones.
5. If you need to take hormonal and other drugs, you should discuss this situation with your doctor., which gives direction to the analysis. Correcting the intake of certain medications will eliminate the likely changes in the results of the analysis.
6. Upon arrival at the laboratory, you need to wait from 15 to 30 minutes to calm down and pass the analysis in the most relaxed state.
7. When prescribing an X-ray examination or physiotherapy procedures on the day of the study, you should first donate blood, and then perform the rest of the manipulations. Some physiotherapy treatments and studies affect the uptake of iodine by the thyroid gland.
8. A few days before the procedure, physical and psychological stress is excluded.. It is worthwhile to transfer all important and exciting things for the time of preparation, to abandon holidays and feasts.
9. On the eve of the study, you should not expose your body to overheating or hypothermia.

Important: immediately before delivery, you can and should drink clean, non-carbonated water.

If a person needs to repeat the analysis at some time intervals, then it is worth performing it in the same medical organization. In this case, it is worth doing this at the same time of day.

When is research required?

For what problems is the analysis assigned:

• if a deviation in the concentration of thyroid hormones is detected;
• if you suspect;
• when a married couple cannot conceive a child, an analysis is prescribed for both a man and a woman;
• there is a problem in the sexual sphere - impotence, frigidity;
• with long-term use of hormonal drugs, any spectrum of action;
• violation of the menstrual cycle in women;
• baldness;
• detection of depression;
• in children with a lag in mental or physical development.

Normal values

After the results are ready with them, you can go to the doctor for a consultation. If a woman is forced to take tests often, then it will be useful to be able to evaluate the results with her own hands.

Important: your own opinion does not replace the full consultation of a specialist.

Normal TSH values ​​by age:

The table shows the change in TSH levels throughout a person's life. The change in the amount of thyroid-stimulating hormone production occurs due to changes in the body, its needs and capabilities.

So a larger amount of TSH at the beginning of life is necessary for the full amount of thyroid hormones in the blood. They are necessary for the normal speed of all metabolic processes. With age, activity slows down, all processes flow more calmly, which means that the level of hormones is adequately lower.

Norms of content and characteristics of thyroid hormones associated with TSH

Important: TSH has a decisive influence on the production of thyroxine and triiodothyronine by the thyroid gland, hormones responsible for stimulating the growth and development of the human body, activating its physical and mental processes. Each of these biologically active substances can exist in the form of two fractions - total and free.

And now more about each of them.

Triiodothyronine

Created in the thyrocytes of the thyroid gland, this hormone enters the bloodstream, where it mainly combines with certain types of proteins. A small amount of T3 remains unbound, free, and it then affects the processes occurring in the body.

The normal content of triiodothyronine, depending on age, is indicated in the table:

A lack of triiodothyronine may indicate:

1. Hypothyroidism.
2. Weight loss.
3. Excessive physical activity.
4. Decreased metabolism.
5. Adrenal insufficiency.

An excess of T3 is observed in women suffering from toxic goiter, as well as from, due to various reasons, thyroid dysfunction.

thyroxine

Interesting: Thyroid cells receive iodine ions and a complex of amino acids from the blood, from which thyroglobulin molecules are created. If it is necessary to obtain thyroxin, thyroglobulin is cut into separate identical fragments, which are excreted into the bloodstream.

The norms for the content of total T4 are indicated in the table:

Standards for the content of free T4:

An increased content of thyroxine is caused by thyrotoxicosis, diffuse goiter and acute thyroiditis, and a reduced content is caused by hypothyroidism and a metabolic failure.

Pregnancy

Hypothyroidism is the leading cause of difficulty in achieving and maintaining pregnancy. Low thyroid function has a negative impact on reproductive health and is more common than most women think.

For women preparing for pregnancy, the study of thyroid function is an important step in achieving a successful result.

Functions of hormones:

• Metabolic control by regulating the rate of oxygen consumption and subsequent production at the cellular level.
• Balance of carbohydrates, proteins and fats.
• During pregnancy, the growth and development of the fetus is controlled by maternal thyroid hormones, only in the later stages are the hormones of the fetus itself included in the process.
• Healthy thyroid function is necessary for the activity of other hormones, like growth hormone, to control heart rate, blood pressure, and normal brain function.

The delicate balance of the endocrine glands

Under the control of the pituitary and hypothalamus are the ovaries and adrenal glands. This is a complex interconnected system, if a violation occurs in one part of it, this is reflected in other glands and hormone production.

Thyroid monitoring is essential for a healthy pregnancy. Her disease develops with a frequency ranging from 10-15%. Thyroid hormone is essential for the placental development of the fetus.

Pregnancy is considered as a "stress test" for the mother's thyroid gland, as she needs to increase the production of hormones by 20-50% to meet the growing needs of her body's metabolism and the growing fetus.

Attention: With elevated TSH values ​​during pregnancy, the patient's condition is corrected by taking drugs that help to successfully bear the fetus and give birth without complications.

If a woman is not able to produce enough hormones due to hypothyroidism, this causes an increased attention of the doctor to pregnancy, an increased risk of miscarriage, premature birth, low birth weight and postpartum developmental problems.

TSH norm in women for conception is in the range of 0.27−4 μIU / ml in serum. The average value of thyroid-stimulating hormone is normally considered to be no higher than 2.5 μIU / ml. TSH values ​​greater than 4 μIU / ml are considered as an increased risk for pregnancy.

Norms of TSH in women table (during pregnancy):

A deviation in the values ​​\u200b\u200bis allowed, this is possible with a high degree of probability when carrying a multiple pregnancy, less often with a singleton.

The reason for the increased TSH is:

• primary hypothyroidism;
• pituitary tumor;
• insufficient level of T4;
• adrenal insufficiency;
• taking antithyroid drugs.

The reason for low TSH is:

• hyperthyroidism (Graves' disease);
• stimulation of the TSH receptor hCG;
• thyroiditis;
• secondary hypothyroidism.

TSH and pregnancy. What is the connection?

The lack of peripheral hormones against the background of high TSH leads to a malfunction in the function of the ovaries as a result, the follicles mature with a defect, and ovulation and the functioning of the corpus luteum are disturbed. High risk of endocrine infertility or miscarriage.

In the absence of conception for a long period, the level of hormones falls under the control of the doctor. Deviations from the norm are subjected to research and find out the cause of the changes for further treatment.

The effect of TSH levels on the female genital area

What is the thyroid-stimulating hormone responsible for in women and what are the consequences of violations of its synthesis in the pituitary gland? The properties of TSH are such that it affects the production of sex hormones that ensure the development of eggs. Gonadotropic hormones regulate the onset and course of menstruation, determine the duration of the cycle.

There are two types of changes in the amount of TSH in a woman's body:

1. Insufficient concentration of thyroid-stimulating hormone of the pituitary gland. In this case, the development of secondary hypothyroidism is characteristic. With a lack of T4 and T3, there is a lack of TESH globulin (testosterone-estrogen-binding) in the body, which depends on them.

At the same time, the concentration of testosterone rises, and this is the male sex hormone. As a result, less active estriol is activated instead of estradiol. The following happens:

• the menstrual cycle lengthens;
• the follicle in the ovary grows more slowly;
• the endometrium in the uterus does not develop enough;
• menstruation is very weak;
• discharge either scanty or profuse;
• the absence of menstruation (amenorrhea) is possible, as a result of the cessation of ovulation;
• uterine bleeding appears without connection with the menstrual cycle;
• development of functional infertility.

TSH affects the menstrual cycle indirectly through other hormones.

1. Excessive concentration of TSH in oncological diseases of the pituitary gland. An increase in the production of thyrotropin leads to phenomena characteristic of hyperthyroidism:

• the interval between periods becomes short;
• menstruation is irregular;
• gonadotropic hormones are synthesized in insufficient quantities;
• cessation of menstruation (amenorrhea);
• menstrual flow very scanty, painful;
• during menstruation, there is a pathological general weakness;
• infertility due to hormonal deficiency is diagnosed.

Both deficiency and excess of TSH in a woman's body leads to persistent menstrual irregularities and infertility.

The effect of TSH on the sexual development of girls

The thyroid-stimulating hormone tsh is the norm in women, due to age and physiological characteristics. A gradual increase in concentration is observed after the reproductive functions fade.

With the development of the genital organs in a girl, disturbances in the hypothalamic-pituitary system can lead to pathological abnormalities. Dangerous, both increased and decreased concentration of TSH in the body.

Thyroid-stimulating hormone norm for women after 50 is higher than for young women, which is explained by the extinction of sexual functions.

1. Low TSH. It leads to the fact that testosterone is activated, so the girl’s body does not produce enough follicle-stimulating hormone (FSH). The synthesis of such an important hormone as luteinizing (LH) also suffers. All this leads to the following consequences:

• there is a lag in development from peers;
• menstruation appears later than physiologically determined terms;
• there is no sexual attraction to the opposite sex;
• underdeveloped mammary glands;
• poorly developed labia and clitoris;
• the figure resembles that of a boy.

The video in this article demonstrates the characteristic appearance of a TSH-deficient girl. The lag in the development of sexual characteristics is fraught with the fact that the girl may have problems in socialization.

1. High concentration of TSH. When the concentration of thyretropin in the blood of a girl is increased, this can accelerate her sexual development. In this case, premature physiological maturation occurs, with significant deviations from the norm. This is due to the fact that a high concentration of TSH stimulates the production of estrogen, luteinizing and follicle-stimulating. As a result, this happens:

• the breast increases in size from the age of 8;
• early appearance of pubic hair;
• the first menstruation appears much earlier than that of peers.

Regular examination of girls for TSH in the blood is important in order to prescribe treatment and prevent pathological disorders in sexual development.

What to do if hormones are not normal

If indicators are detected that are outside the norm, all decisions are made by the endocrinologist. His instructions for action will make it possible, as soon as possible, to normalize TSH levels in the blood and avoid the development of a severe endocrine disease.

Nowadays, you can donate blood for TSH thyroid hormones without difficulty. It can be performed in the direction of a doctor in a budgetary medical institution. Or go to a commercial laboratory, now the cost of performing a study is not high and everyone who cares about their health can afford to do it.

In order to get a reliable result, you need to know how to properly take an analysis for TSH. A woman will have to take a second analysis, or undergo unnecessary additional examinations if improper preparation will adversely affect the result.

Elevated TSH

A short and slight increase in thyrotropin can also be observed as a result of the analysis of a healthy woman, the reason for this is taking an anticonvulsant medication or physical work. But if the increase in the level of the hormone is very different from the norm, then this may indicate illness.

The main symptoms of elevated thyrotropin levels are anxiety, irritability, tremors, fatigue, and insomnia. visual impairment is possible.

A short list of diagnoses, a symptom of which may be an increase in TSH:

• malfunction of the thyroid gland or adrenal glands;
• tumor;
• increased dosage of iodine-containing medicines;
• mental or somatic disorders;
• pregnancy (in some cases);
• lead poisoning;
• unregulated secretion of TSH;
• hemodialysis;
• preeclampsia;
• removal of the gallbladder.

Of course, only a doctor can understand the result of the tests and make a final diagnosis. It should be borne in mind that in women after 30 years, the level of thyrotropin may be slightly increased and this will be a variant of the norm, since some medications and increased physical activity may have an effect on the indicator.

Decreased TSH level

It is especially important to contact an endocrinologist and pass an analysis to check the level of thyroid-stimulating hormone if the following symptoms appear in everyday life: headache, drowsiness, memory impairment and tolerance to changes in weather temperatures, lethargy, swelling, increased pressure and body temperature, overweight.

Reduced thyrotropin can be a sign of the following diseases:

• decreased function of the pituitary gland;
• trauma or neoplasm in the pituitary gland;
• inflammation of the pituitary gland, due to which the production of hormones is reduced;
• death of pituitary cells in the female body, as a complication after childbirth;
• neoplasm in the body of the thyroid gland;
• toxic goiter;
• Plummer's disease;
• mental illness;
• excess hormones due to improper intake of hormonal drugs;
• fasting or low-calorie diet;
• severe stress.

Treatment

Treatment is aimed at normalizing the concentration of TSH in the blood, and this requires regular analysis to monitor indicators. Therapy is carried out until the results of the studies show the norm.

Note that in some cases, drugs may not give a positive trend, therefore, the level of TSH remains the same. In this case, the doctor is obliged to replace the prescribed therapy.

Treatment is best carried out at the initial stage when the first symptoms appear, this will bypass further surgical intervention.

The endocrine glands, which form part of the endocrine system, control most of the processes in the body. They synthesize hormones, the function of which is to ensure that all organs and systems work smoothly. One of the most important hormones is thyrotropin (TSH).

TSH is synthesized by the anterior pituitary gland. It is directly involved in the production of the hormones T3 and T4. Under the influence of various reasons, the level of thyroid-stimulating hormone can increase. High TSH is not a generalized disease, but a symptom of certain disorders in the body. To normalize the level of the hormone, it is necessary to find out the root cause of the increased rates.

Hormone functions in the body

Thyrotropic hormone is a direct participant in the synthesis of T3 and thyroid hormones. These hormones are responsible for metabolic processes in the body, the formation of proteins, growth and development.

The main function of TSH is to regulate the functions of the endocrine system. The hormone controls important processes:

• regulation of metabolism;
• production of protein, retinol;
• breakdown of nutrients into simpler components;
• normalization of the activity of the central nervous system, gastrointestinal tract, cardiovascular system.

TSH accelerates the production of phospholipids and nucleic acids, and also stimulates the supply of iodine to the thyroid gland. If there is a violation of the level of thyroid-stimulating hormone, respectively, the values ​​of T3 and T4 change.

Norm of indicators

The concentration of the hormone in the blood is not a statistical unit. It can change with age, fluctuate throughout the day.

Possible complications and consequences

If a high level of TSH persists for a long time, it can lead to the development of irreversible changes in the body.

In children, an increase in the hormone can cause:

• inhibition of mental and physical development (possible cretinism);
• violation of the manifestations of secondary sexual characteristics;
• decreased immunity, which is expressed by frequent colds, relapses of chronic diseases;
• heart problems;
• marked weakness.

In adults:

• decrease in intellectual abilities;
• hypotension;
• long-term chronic pathologies;
• violation of the menstrual cycle in women;
• atrophy of the genital organs;
• sexual dysfunction.

TSH level correction

An increase in thyroid-stimulating hormone requires correction. If the deviation from the norm is insignificant, then the hormonal background can be restored by normalizing the diet and lifestyle. With very high TSH levels, the level of T3 and T4 decreases, which is very dangerous for health. In this case, hormone replacement therapy is prescribed. It is recommended to take Thyreotom or Thyreocomb. During pregnancy, small dosages of synthetic (L-thyroxine) may be prescribed. Treatment with hormonal drugs can last from several months to several years. Sometimes lifelong medication is required.

If the level of TSH is elevated against the background of the presence of tumor formations, the treatment is longer and more complex. More often you have to resort to surgical intervention to remove the neoplasm.

With an iodine deficiency in the body, the intake of iodine-containing drugs and an increase in the diet of products with iodine are prescribed.

To slow down the progression of the destruction that occurs in the body due to a high level of TSH, additional treatment is carried out using certain groups of drugs (hormone replacement therapy remains basic):

• vitamins (Aevit, Neurobeks and others);
• female sex hormones to normalize the menstrual cycle;
• cardioprotectors (Riboxin, Trimetazidine);
• glycosides (Strophanthin, Korglikon);
• to improve brain activity - nootropics, neuroprotectors.

An increase in thyroid-stimulating hormone is an alarming bell, indicating disorders in the body. The appearance of suspicious symptoms that may indicate a hormonal failure should be the reason for the examination. After finding out the causes of hormonal disorders, the doctor should prescribe treatment in accordance with the results of the diagnosis and the characteristics of the clinical picture.

The human body is sensitive to any hormonal changes. When the TSH index in the blood changes, symptoms appear from various organs and systems: the heart, gastrointestinal tract, nervous system, and even the psyche.

Prolonged hormonal disorders lead to serious diseases, up to oncopathology. Most often, ladies are interested in why TSH is elevated and what it means for a woman.

TTG - what is it and what are the norms?

TSH is an abbreviation used when taking a blood test for thyroid hormones. Thyroid-stimulating hormone (thyrotropin) is synthesized in the pituitary gland. Why is a TSH test prescribed for suspected thyroid disease? It's simple: thyroid-stimulating hormone regulates the level of T3 (decoding - triiodothyronine) and T4 (full name - thyroxine) synthesized in the thyroid gland.

If these active substances are not produced enough, for example, with hypothyroidism, the pituitary gland increases the production of TSH. Thyrotropin "spurs" the thyroid gland for the active synthesis of hormones. If the level of T3 and T4 in the blood is too high (thyrotoxicosis, diffuse goiter), then the pituitary gland, inhibiting the synthesis of TSH, “removes” the thyroid-stimulating factor.

A clear relationship - thyrotropin is increased, T3 -T4 is lowered and vice versa - is fixed only in the absence of pathology of the pituitary gland and hypothalamus. These two glands, located in the brain, act as the main "controllers" of the thyroid gland.

The level of thyrotropin is maximum in newborns (1.1-17.0) and gradually decreases up to 14 years. From this age in women, the normal TSH level varies within 0.4-4.0 mU / l. The value of thyrotropin even in a healthy woman changes during the day, so it is recommended to take a hormone test in the morning, on an empty stomach. The day before blood donation, it is recommended to refuse fatty foods, alcohol, even taking vitamin complexes. If the patient receives hormone replacement therapy, the course is usually interrupted for 2 weeks. before taking the test as directed by the doctor.

Important! A woman can take an analysis for TSH on any day of the menstrual cycle. The phase of the menstrual cycle does not affect the level of thyrotropin.

A slightly elevated TSH of the thyroid gland, which is not constant over time, is not considered a pathology. This condition can occur after heavy physical exertion or provoked by taking anticonvulsant drugs. However, a single case of deviation is not accompanied by organic disorders of the thyroid gland. A temporary increase in TSH is not accompanied by abnormalities recorded on ultrasound.

The endocrine system sometimes reacts quite violently to pregnancy. So, the TSH indicator in the expectant mother is significantly reduced in comparison with the age norm and depends on the gestational age:

• in the first trimester (the first 3 months of gestation) - 0.1-0.4;
• in the II trimester (3-6 months of pregnancy) - 0.3-2.8;
• in the III trimester (from 6 months to delivery) - 0.4-3.5.

Minor deviations from normal values ​​are not considered as a sign of a pathological process.

What pregnant women need to know about TSH:

• The regulations differ slightly from country to country. So, in the USA, the TSH rate is slightly lower than Russian indicators. However, even in our country, some doctors adhere to different limit values: 3 or 4 mU / l.
• The safe limit of TSH for a woman planning a pregnancy is 2.5 mU / l. Exceeding this level can lead to problems during pregnancy.
• Only an endocrinologist (not a gynecologist!) can prescribe iodine preparations during pregnancy. An overdose of iodine-containing drugs can provoke an increase in the hormone during pregnancy.
• Every fourth pregnant woman has TSH slightly below normal, and in multiple pregnancies, thyrotropin levels often drop to 0.
• If in the first trimester the TSH hormone is elevated to significant levels, there is a high risk of miscarriage, the development of abnormalities in the fetus (mental abnormalities, mental retardation) and pregnancy complications (gestosis - preeclampsia). In such cases, a full examination of the woman and further therapy are required.

Hormonal imbalance occurs against the background of physical overstrain, a violent emotional reaction to various events. However, this reaction is most often temporary and does not carry the risk of developing serious diseases.

A prolonged increase in TSH can be observed with prolonged depression, insomnia, starvation or a strict diet, taking certain drugs (beta-blockers for hypertension, antipsychotics, Prednisolone and Cerucal, estrogens, iodine preparations in excessive dosages). Sometimes an excess of the norm is the result of an overdose of thyreostatic drugs, for example, Mercazolil. An overestimated level of thyrotropin on repeated studies indicates a serious violation in the female body.

Important! Exceeding the norm of TSH is recorded after resection of the gallbladder and in old age.

An increase in thyrotropin is considered in conjunction with a change in T3, T4:

• Euthyroidism - TSH and T4 without significant changes;
• Subclinical hypothyroidism - TSH above 10 honey / l, T4 and T3 are normal;
• Explicit hypothyroidism - increased TSH, T2 and T3 are underestimated;
• High TSH with concomitant hyperthyroidism (a sign of hormone insensitivity) - TSH and T4 are elevated.

Organic causes of elevated TSH in women:

• Hypothyroid state that has arisen against the background of surgical excision of the thyroid gland, hemodialysis or radioiodine therapy - exceeding the norm of TSH up to 10 times, T4 is reduced;
• Autoimmune thyroiditis in the phase of subclinical hypothyroidism (including postpartum thyroiditis) - TSH is elevated, T4 is normal;
• Autoimmune thyroiditis in the phase of obvious hypothyroidism - TSH is more than 10 honey / l, T4 is reduced, antibodies to TPO are determined;
• Endemic goiter in the stage of subhypothyroidism - TSH at the upper limit or slightly increased, T4 at the lower limit or reduced, T3 at the upper limit of normal;
• Endemic goiter at the stage of hypothyroidism - high levels of thyrotropin, low levels of T4 and T3;
• Primary adrenal insufficiency - against the background of a low level of cortisol, TSH is slightly increased (usually no more than 15 honey / l);
• Hyperprolactinemia - often indicates a pituitary tumor (sometimes occurs with polycystic ovaries, cirrhosis of the liver, chronic renal failure), TSH is elevated, T4 is normal;
• Genetically determined immunity of thyroid hormones by the pituitary gland - regardless of the level of thyroid hormones (usually significantly higher than normal), TSH is high, and symptoms of thyrotoxicosis appear;
• The insensitivity of all body tissues to thyroid hormones is a serious condition, accompanied by growth retardation and mental disorders.

Important! Often in women after 50 years of age, TSH is elevated with the development of breast cancer and is an indirect indication of oncopathologists. Sometimes TSH-produced tumors develop in the lungs.

The nature of the pathology is determined by instrumental examination - ultrasound, computed tomography. Thyroid hormone tests allow you to determine the stage of the pathological process.

Symptoms of deviation of the level of TSH from the norm

A slight increase in thyrotropin usually does not cause painful symptoms in women. The complete absence of complaints or mild symptoms are also characteristic of subclinical hypothyroidism, when T4 is within normal limits. Severe symptoms of endocrine disorders appear at a TSH level of 7.0-75 mU/l.

Women present the following complaints:

• swelling of the face, thinning of the outer third of the eyebrows;
• pale and excessively dry skin;
• dull brittle hair, delamination and weakness of the nail plate;
• weakness, constant drowsiness;
• depression of emotions, depressive states and increased irritability;
• rare pulse, decrease / increase in a / d;
• weight gain against the background of poor appetite, constipation;
• anemia.

High TSH: what to do?

If a high level of thyrotropin is detected, you should contact an experienced endocrinologist. Monitoring of T3 and T4 indicators, ultrasound of the thyroid gland, x-ray of the pituitary zone is the main diagnostic complex that allows you to determine the nature of the pathology.

With an increased TSH of the thyroid gland of more than 7 mU / l, the endocrinologist prescribes synthetic hormones - L-iroxin, Bagothyrox or Euthyrox. The dose is selected individually and adjusted during treatment, taking into account the blood test. In most cases, a woman takes synthetic hormones for life.

Only with a slight increase in TSH (subclinical hypothyroidism, euthyroidism with normal T3 and T4 levels) can a normal level be restored without hormone therapy. The medical complex includes a strict correction of nutrition (exclusion of gluten and casein), education of psycho-emotional stability, taking multivitamin preparations and observing the correct work and rest regimen.

The nuances of the treatment of high TSH:

• Iodine-containing drugs are used to treat only iodine deficiency and endemic goiter. With damage to the tissues of the thyroid gland, which is detected in most cases, taking iodides is useless.
• No medicinal herb contains substances identical in composition and action to thyroid hormones. Therefore, replacing drug therapy with folk remedies is impractical and life-threatening.
• In subclinical hypothyroidism, pregnant women are prescribed hormonal drugs without fail.

Conclusion and forecast

Although critically high TSH and hypothyroidism rarely leads to death, with a long-term increase in the level of the hormone, a woman runs the risk of “acquiring” a number of serious diseases, being overweight of which is only the most harmless consequence.

Persistently high values ​​of thyroid-stimulating hormone are fraught with the development of atherosclerosis, hypertension and diabetes mellitus, and mental disorders. The most severe prognosis concerns patients suffering from insensitivity to thyroid hormones of the pituitary gland or the whole body.

In such cases, high-dose hormonal treatment is required. Medicinal compensation will not eliminate already developed mental disorders, but will stop their progression.
