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.
Depending on your risk profile, your doctor may recommend a thyroid-stimulating hormone (TSH) blood test. TSH is released by the pituitary gland; when the thyroid bogs down, the pituitary releases more TSH. If you have normal levels of TSH, your test score will be from 0.4 to 2.5. A score between 0 and 0.4 is hyperthyroidism. Between 2.5 and 4 means you are at risk for hypothyroidism, and should be retested within a year.
