This signal is called thyroid stimulating hormone (TSH). As the name implies, this hormone stimulates the thyroid to produce thyroid hormone and to grow in size. This abnormal growth in size produces what is termed a âgoiter.â Thus, iodine deficiency is one cause of goiter development. Wherever iodine deficiency is common, goiter will be common.
Thyroid-stimulating hormone (TSH, thyrotropin) is generally elevated in hypothyroidism and decreased in hyperthyroidism. It is the most sensitive test for thyroid hormone function. TSH is produced in the pituitary gland. The production of TSH is controlled by TRH, which is produced in the hypothalamus.
