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.
Functions of the thyroid gland. The thyroid gland regulates the body's metabolism and growth, and secretes several hormones: thyroxine (T4), triiodothyronine (T3), and calcitonin. Thyroid problems can affect female patients of any age.
