Overview

Graves' disease is an immune system disorder that results in the overproduction of thyroid hormones (hyperthyroidism). Although a number of disorders may result in hyperthyroidism, Graves' disease is a common cause.

Thyroid hormones affect many body systems, so signs and symptoms of Graves' disease can be wide ranging. Although Graves' disease may affect anyone, it's more common among women and in people younger than age 40.

The primary treatment goals are to reduce the amount of thyroid hormones that the body produces and lessen the severity of symptoms.
