What is Hypothyroidism?

Hypothyroidism, also called underactive thyroid, is a condition in which the thyroid gland does not produce enough hormones. Hypothyroidism can be caused by the autoimmune disorder Hashimotos thyroiditis, irradiation or surgical removal of the thyroid gland, and medications that reduce thyroid hormone levels. Anyone can develop hypothyroidism, but people who are most at risk include those who are over age 50 and female. However, only a small percentage of people have full-blown (overt) hypothyroidism. Many more have mildly underactive thyroid glands (subclinical hypothyroidism).

Diagnosis and Treatment

Hypothyroidism can cause serious complications if left untreated. Fortunately, it can be easily diagnosed with blood tests that measure levels of the thyroid hormone thyroxine (T4) and thyroid-stimulating hormone (TSH). Your doctor may also want to test for antithyroid antibodies and check your cholesterol levels. Based on these test results, the doctor will decide whether to prescribe medication or simply have you get lab tests every 6 - 12 months.
