What is thyroid stimulating hormone high side

Thyroid

stimulating hormone (TSH) is a hormone secreted by the pituitary gland that promotes thyroid hormone synthesis and secretion. When hypothyroidism occurs, thyroid hormone synthesis and secretion decrease, resulting in an increase in TSH levels to stimulate the thyroid to return to normal function.

Common causes of hypothyroidism include Hashimoto's thyroiditis, radioactive iodine therapy, thyroid surgery, iodine deficiency, etc. In addition, certain medications (e.g. lithium, thioureas, etc.) may also cause elevated TSH levels.

Treatment for elevated TSH levels depends on the cause. For hypothyroidism, it is usually prescribed to supplement thyroid hormones, such as levothyroxine sodium (LT4). Regular monitoring of TSH levels during treatment is necessary to adjust the dose of the drug. It

should be noted that high TSH levels do not necessarily mean thyroid disease, but may also be related to other diseases, such as pituitary disease, renal failure, etc. Therefore, if TSH levels are elevated, it is recommended to seek medical attention in time for relevant examinations to clarify the cause and formulate corresponding treatment plans.
