By Mayo Clinic staffGraves' disease is the most common form of hyperthyroidism, occurring when your immune system mistakenly attacks your thyroid gland and causes it to overproduce the hormone thyroxine. This higher thyroxine level can greatly increase your body's metabolic rate, which may affect you in numerous ways, from your moods to your physical appearance.
Graves' disease is rarely life-threatening. Although it may develop at any age and in either men or women, Graves' disease is more common in women and usually begins after age 20.
There's no way to stop your immune system from attacking your thyroid gland, but treatments for Graves' disease can ease symptoms and decrease the production of thyroxine.
