Graves' disease is an autoimmune disorder and a common cause of hyperthyroidism, or an overactive thyroid gland. A person suffering from Graves' disease has a thyroid that produces too many hormones. These hormones affect different bodily functions and parts of the body, so Graves' disease symptoms are diverse. 

Graves' disease is usually not life-threatening and is easy to treat. Getting control of Graves' can be simple, yet it will greatly improve quality of life and general well-being. Easy to treat and spot, Graves' can go into remission and become a non-issue. If the disease is left untreated, however, Graves' disease symptoms can get worse and cause serious health complications. 

Treatment usually involves stopping the overproduction of the thyroid hormones with prescription medication.
