What is thyrotropic hormone in women responsible for?

So, what is a thyroid stimulating hormone in women? TSH, or thyroid stimulating hormone, or thyroxin, a thyroid hormone produced by the hypothalamus. This substance can change its concentration in the blood throughout the day, while this process is the norm. If, of course, the patient does not complain of the presence of ailments and anxious symptoms( see below).

Functions of TSH

What is TSH hormone in women responsible for? Thyroxin performs a whole range of vital functions, and regulates the work of not only the endocrine system in general and the thyroid gland in particular, but also without exaggerating the entire body. Reducing or increasing the level of this substance causes the appearance of ailments, reduces the efficiency and quality of life, so it is important to understand when to seek medical help.

Its main functions are:

  • regulation of the functioning of the thyroid gland;
  • organization of the reproductive system;
  • stimulating the synthesis of vitamin A by the liver;
  • removing excess "bad" cholesterol;
  • ensuring the oxygenation of whole body cells;
  • stimulation of cell saturation with iodine compounds.

As can be seen, the functions of thyrotropin, tetraiodothyronine, and triiodothyronine are similar. However, the indicators of the hormone hormone TSH in women are strikingly different from those in other thyroid hormones. In order not to get confused in concepts, we consider this question in more detail.

TSH norm in women: by age and during

normalcy, in the case of TDT in women: by age and in

, the rate of TJT in women is as follows: for age and in

.In addition, the level of this substance is influenced by the time of day and the patient's condition. So, in pregnant women, the concentration of the hormone is somewhat different from that in non-pregnant women, but since this is a purely physiological factor, it’s not worth worrying about.

Norm TSH in women by age is presented in the table. The substance level is measured in international units per liter( honey / l or IU / l).

Age Norm
Newborn Girls Within 1.1 - 17
Girls under 2.5 months In the range of 0.6 - 10
Up to 2 years 0.4 - 7
2 years - 5 years - 6
5 - 14 years From 0.4 to 5

The rate of thyroid-stimulating hormone for girls over 14 years old and adult women is from 0.4 to 4. Of course, these indicators can fluctuate due to certain circumstances, but if you feel complaintsor there are no other deviations, do not worry.

The rate of TSH in women after 50 is considered to be indicators that do not exceed 4 IU / L, which is explained by the hormonal changes that occurred during the onset of menopause. Hence, all the symptoms characteristic of menopause: sweating, mood swings, weakness, headaches, etc. Such deviations cause discomfort, therefore, require mandatory treatment.

Norm in pregnant women

The rate of thyroid hormones in women during pregnancy is shown in the table.

time normal level( IU / l)
1 trimester 0,1 - 2 2
trimester 0,2 - 3 3
trimester 0,3 - 3

Thus, examining information on normal TSH hormone in womenage, and given the tolerances( which may be due to hormonal drugs, including contraceptives, surgical interventions and other factors), the patient herself can conclude whether she needs further examination. Although the final decision is made by a doctor, still, the vigilance and attentive attitude of a woman to her health sometimes becomes an obstacle to the further progression of the disease, if there is one.

Other indicators

During the examination for the presence of endocrine system pathologies( in particular, the thyroid gland), a biochemical blood test is performed not only on thyrotropin, but also on the content of other hormones SchZ: T3 and T4.

So, if in adult women TSH is 4-4.5 IU / L, and T4 is free - 9 - 22 pmol - this is the norm, indicating a full and harmonious work of the whole organism. Triiodothyronine, or T3, however, should not exceed 2.6 - 5.7 pmol( pmol) per liter of blood. Deviations are permissible for the above reasons, but for the sake of their own safety, the patient, nevertheless, should be consulted by a doctor.

  • hypothyroidism;
  • adrenal insufficiency;

  • heavy metal poisoning.

Also, an elevated level of thyrotropin is observed during excessive physical exertion, after removal of the gallbladder or taking certain groups of drugs.

If the rate of TSH for women in the blood test is reduced, this may be due to:

  • hyperthyroidism, which is often accompanied by a pathological condition such as thyrotoxicosis;
