What is the normal thyroid stimulating hormone? Thyroid is a very common immune disorder in life and many people in life suffer from this problem. When thyroid disease occurs, the damage to the patient’s health is significant, which can be indirectly illustrated by the number of patients treated clinically. Let’s learn together: what is the normal thyroid stimulating hormone? The normal range of thyroid stimulating hormone is 2-10 mU/L. If it is not in this range, it means that the health is damaged and needs to be checked. 1.Check introduction Thyroid stimulating hormone can promote thyroid follicular epithelial cell proliferation and thyroid hormone synthesis and release. 2.Increases Primary hypothyroidism, Hashimoto’s disease with hypothyroidism, exogenous thyroid hormone-secreting tumors (lung, breast), and recovery from subacute thyroiditis. Intake of lithium metal, potassium iodide, and thyrotropin-releasing hormone can increase thyroid stimulating hormone. 3.Decrease Pituitary hypothyroidism, hyperthyroidism due to non-thyroid hormone tumors, and intake of aspirin, corticosteroids and intravenous heparin. 4. Special Note Hashimoto’s disease, also called Hashimoto’s thyroiditis and chronic lymphocytic thyroiditis, is an autoimmune disease (i.e., one’s own immune system attacks one’s normal tissues and organs, causing a decrease in normal function). It is more common in middle-aged women and often presents as a diffuse enlargement of the thyroid gland with advanced signs of hypothyroidism. Thyroid stimulating hormone (TSH) is a hormone secreted by the pituitary gland that promotes the growth and function of the thyroid gland. In humans, TSH is a glycoprotein containing 211 amino acids, with sugars making up about 15% of the entire molecule. The entire molecule consists of two peptide chains, the alpha chain and the beta chain, and TSH promotes the functions of the thyroid gland in a comprehensive manner, with a slightly earlier appearance to promote the release of thyroid hormones and a slightly later appearance to promote the synthesis of T4 and T3, including strengthening iodine pump activity, enhancing peroxidase activity, promoting thyroglobulin synthesis and tyrosine iodination, and other aspects. . Thyroid stimulating hormone causes cells to proliferate in a high columnar pattern, resulting in an enlarged gland. TSH secretion by the pituitary gland is influenced by the thyrotropin-releasing hormone (TRH) secreted by the hypothalamus on the one hand, and by the feedback inhibitory effects of T3 and T4 on the other, both of which are antagonistic to each other and form the hypothalamic-pituitary-thyroid axis. Under normal conditions, the amount of TRH secreted by the hypothalamus determines the level of feedback regulation of the pituitary-thyroid axis; if more TRH is secreted, the regulation point of T3 and T4 levels in blood is high; when T3 and T4 in blood exceed this regulation level, the feedback inhibits TSH secretion by the pituitary gland and reduces the sensitivity of the pituitary gland to TRH, thus keeping T3 and T4 levels in blood relatively constant. TSH secretion has a circadian rhythm, with the highest level in the morning at 2-4 a.m. and the lowest at 6-8 p.m.
