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.
The thyroid is a butterfly-shaped gland in the front of the neck. It produces hormones that control the speed of your metabolism - the system that helps the body use energy. Thyroid disorders can slow down or rev up your metabolism by disrupting the production of thyroid hormones.
