Hypothyroidism (underactive thyroid) Overview. Hypothyroidism (underactive thyroid) is a condition in which your thyroid gland doesn't produce enough of certain important hormones. Women, especially those older than age 60, are more likely to have hypothyroidism. Hypothyroidism upsets the normal balance of chemical reactions in your body.
Its job is to make thyroid hormone. If the gland is underactive, it may not make enough thyroid hormone. Thyroid hormones control how your body uses energy. They affect almost every organ in your body. When your thyroid doesnât make enough of these hormones, parts of your body slow down.
