Thyroid stimulating hormone is produced by the lower cerebral appendage and belongs to the regulatory. It indirectly affects metabolic processes. If TSH is elevated, then there are problems in the endocrine system, which, in turn, negatively affects the whole body.

TSH or thyroid stimulating hormone - general characteristics

A hormone created in one of the brain regions is produced in both men and women. Plays a dominant role in the formation of triiodothyronine (T3) and thyroxine (T4) in the thyroid gland. These substances are responsible for many aspects of the body's systems.

Due to the fact that TSH interacts very closely with T3 and T4, to identify the correct indicator of one, the other two must be taken into account.

The rate of the hormone TSH


The level that is healthy for a particular person varies depending on the age criterion. In addition, it is influenced by the presence of pregnancy. The highest concentration is recorded in children.

Thyroid-stimulating hormone norm table

Age TSH, honey / l
1 to 4 days from 1 to 39
2 to 20 weeks from 1.8 to 9.0
20 weeks to 5 years from 0.4 to 6.5
5-14 years old from 0.4 to 5.0
14 to 21 years old from 0.3 to 4.0
21 to 54 years old from 0.4 to 4.2
Over 55 years old from 0.5 to 9.0

Pregnancy rate table

Trimester TSH, honey / l
The first from 0.3 to 2.5
Second from 0.5 to 4.6
Third from 0.8 to 5.2

The hormone level changes over the day. The highest is observed at night - between 2:00 and 4:00 hours. Least of all TSH in the evening - from 17:00 to 18:00.

Causes of elevated thyroid-stimulating hormone


Abnormal values ​​always appear in connection with something. By itself, a sharp increase is not an indicator of a pathological condition, because this phenomenon can be provoked by the drugs taken, physical activity, nervous overexcitation and many other factors that the human body is exposed to.

But long-term TSH levels above normal signal the following:

  • ailments of the thyroid gland or the consequences of its removal;
  • acute iodine deficiency;
  • the result of resection of the gallbladder;
  • severe form of gestosis (II - III trimester of gestation);
  • aggravated or chronic pathology of the gastrointestinal tract, respiratory, urinary, cardiovascular systems;
  • lead poisoning;
  • a tumor in the lungs, mammary glands, thyroid gland, pituitary gland;
  • dysfunction of the adrenal glands.

The risk factor includes people with autoimmune diseases, people with a hereditary predisposition, living under constant stress or following a strict diet.

Features during pregnancy


Starting from the first trimester of gestation, hormonal analysis shows a low level of TSH, but, in the future, up to childbirth, it increases. This is not considered a deviation, because at the 18th week, the child's thyroid gland and the T3 and T4 substances produced by the mother begin to work unnecessarily.

The reasons for the high level of the hormone in early pregnancy related to the pathological condition:

  • Hypothyroidism is poor thyroid performance. It cannot cope with the need to produce more in order to provide its own body and fetus with the required substance. The pituitary gland comes into play to spur the formation of T3 and T4. A dangerous condition for the development of the fetus.
  • Hyperthyroidism is a common disease that causes increased thyroid function.
  • A neoplasm in the pituitary gland.
  • Gestosis, severe toxicosis - accompanied by edema, the appearance of protein in the urine and high blood pressure. Frequent manifestation, if the child's father has a negative blood Rh factor, and the mother has a positive one. There is a rejection of the fetus.
  • Diseases of the respiratory, cardiovascular and nervous systems.
  • Depression, frequent stress, nervous overexcitation.
  • Smoking, alcoholism, drug addiction, substance abuse, etc.
  • Strong intoxication with mercury, lead, zinc.
  • Physical exercise.

If a deviation from the norm is detected, the doctor leading the pregnancy prescribes additional diagnostic procedures to identify the cause of this phenomenon. In this case, all new signs of malaise must be taken into account.

Symptoms of elevated TSH


There is a separate classification of signs of high thyrotropin levels in the human body.

Nervous system:

  • fatigue quickly sets in;
  • difficult to concentrate;
  • lethargy;
  • slowed down and unclear thinking;
  • poor memory;
  • drowsiness, lethargy, apathy;
  • trouble falling asleep, unstable sleep;
  • depression, depressive state.

The cardiovascular system:

  • hypotension (hypotension) - blood pressure is 20% less than the usual indicator, in absolute numbers - below 90 systolic and below 60 arterial;
  • tachycardia;
  • swelling.

Gastrointestinal tract:

  • constant feeling of hunger due to improper metabolism;
  • appetite can be reduced due to general lethargy;
  • nausea;
  • an enlarged liver;
  • irregular stools.

Reproductive system:

  • inaccuracy of the menstrual cycle;
  • decreased libido;
  • a severely neglected case is fraught with infertility.


  • the neck looks thick;
  • poor condition of the skin and hair;
  • the tone of voice decreases.

General well-being:

  • low temperature (up to 35 ° C);
  • weakness;
  • cramps and pain in the lower extremities;
  • excess weight appears with a constant diet;
  • increased sweating;
  • low hemoglobin.

Elderly people are also characterized by shortness of breath, rapid heartbeat and chest pain.

Children are characterized by hyperactivity, nervousness, increased excitability, anxiety.

Normalization methods


Correction of hormonal levels can only be carried out with the recommendation of a doctor, after an accurate diagnosis has been made. The effectiveness of treatment is highly dependent on the source of the disease, because therapy has an individual character. First of all, the effect is on the root cause of the pathogenic state.

An abrupt increase, provoked by the thyroid gland or breast cancer, requires an integrated approach with long-term wellness manipulations. If the tumor is large, surgery is indispensable. It will take a long time to restore efficiency and treat the expected consequences.

A slight increase in thyrotropin due to iodine deficiency is eliminated with medication and proper nutrition. Six months of taking iodine-containing drugs, and then re-examination.

Interesting! To prevent this condition, people prone to thyroid problems buy iodized salt instead of ordinary. But few people know that potassium iodide decomposes during heat treatment and the dish will no longer have the desired effect. Much more effective is the use of salt with potassium iodide (KIOZ), which is sold in special stores or pharmacies.

Hypothyroidism causes hormonal therapy, the scheme of which is drawn up by a physician. Previously, people used drugs based on animal glands, but now they have been successfully replaced with chemically synthesized substances with greater activity than their natural counterpart.

At home, well-known folk methods are suitable that will enhance the effectiveness of traditional therapy: beet tincture, herbal decoctions.

After completing the course of treatment, it is necessary to undergo an annual re-examination for relapse. If you ignore this condition, the disease will return imperceptibly and move into a more serious stage.

Complications and consequences


Diagnostics made on time is a kind of prophylaxis and will help to detect pathology, starting to fight it before the onset of critical consequences. As a rule, such patients recover without serious complications for the body. The exception is cases with tumors, cancer, or removal of the gland.
