TTG. The norm of the level of the hormone in the blood

Currently, in medical practice, the trend is actively developing to study the functions of hormones. The use of hormonal therapy at the present stage has made it possible to apply it not only as a substitution therapy, but also as a separate medication that promotes rapid and effective recovery. As medicines, hormonal preparations are used practically in all fields of medicine, among them the most actively uses these pharmaceuticals dermatology.

Thyrotropic hormone provides control and regulation of the synthesis of hormones by the thyroid gland. TTG norm in children is primarily determined by age. Thus, in newborns, the level of the hormone varies from 1.1 to 17 in terms of international units. In the age group younger than 2.5-3 months, thyroid-stimulating hormone levels range from 0.6 to 10. In children up to a year, the upper limit is reduced to 7 units. Why do newborns have such a high level of hormones? This is primarily due to the fact that the development of the nervous system of children requires a high level of thyroid hormones. In the process of completing the formation of the nervous system, the level of the latter gradually decreases. It is necessary to monitor the level of hormonal changes in children, since if the thyroid does not decrease - this will indicate an inborn hypothyroidism. If there is no treatment for this disease, mental retardation may develop.

Why do we need this norm?

Knowledge of normal hormone levels is necessary for assessing the state of the human endocrine system. So, exceeding the levels of thyroid-stimulating hormone most often indicates a pathology of the thyroid gland (hypothyroidism). In addition, a change in the hormonal background in the direction of increase may indicate a deficiency of the adrenal glands, tumors of the pituitary gland and even mental illnesses.

The norm of TTG in pregnancy differs from that for a given age group. The onset of physiological changes in the body of a pregnant woman leads to an increase in thyroid-stimulating hormone. In addition, the norm for women also depends on the phase of the menstrual cycle. The increase in the level of the hormone can be caused by the use of certain pharmaceutical preparations, as well as by active physical activity.

When there is a decrease in the level of TTG?

The low level of the pituitary hormone can be caused by both normal (physiological) changes and pathological processes in the human body. TTG norm decreases with starvation, psychoemotional stresses, as well as in the treatment of hormonal drugs. In the case of a pathological condition, a low level of thyroid-stimulating hormone may indicate diseases such as hyperthyroidism, decreased function or trauma to the pituitary gland.

The blood test for hormones is carried out in a specialized laboratory. Blood sampling is carried out in the morning on an empty stomach. As already described above, this norm is determined both by the functional state of the organism, and by the pathological changes in it. The level of thyroid-stimulating hormone in men is slightly lower than that of women, and in elderly people it is reduced even more due to the slowing of the activity of physiological processes.

Thus, the value of the level of hormones in general, as well as in particular, is very high. Changes in the indicators make it possible to suspect the pathological changes taking place, to conduct additional studies and to make a diagnosis. Treatment in this case, if possible, is aimed at eliminating the initiating change in the factor. In the case where this possibility is not available, substitution therapy is provided.
