Thyroid-stimulating hormone (TSH) is a hormone that plays an important role in regulating thyroid function. This hormone is produced by the thyroid gland and enters the bloodstream. TSH affects the activity of the thyroid gland, which produces thyroxine and triiodothyronine, hormones necessary for the normal functioning of the body.
TSH stimulates thyroid function and increases thyroid hormone levels. This occurs due to an increase in the number of thyrotropin receptors that are located on the surface of thyroid cells. At the same time, the synthesis of thyroxine and trithyronine increases. However, with excessive levels of thyroid-stimulating hormone, dysfunction of the thyroid gland and even its destruction are possible. Therefore, to maintain normal levels of hormones in the body, it is necessary to control the level of TSH in the blood. For this purpose, special studies are carried out, such as a blood test to determine the level of TSH.
Insufficient TSH levels can lead to hypothyroidism, which is characterized by decreased activity of the thyroid gland. In this case, replacement therapy with thyroid hormone drugs under the control of TSH levels is required to maintain normal levels of hormones in the body. TSH also plays an important role in many other processes related to hormones and metabolism in the body. They regulate the functioning of most endocrine glands, so
