Graves' Disease is an autoimmune disorder that affects the thyroid gland, causing it to become overactive. This leads to an excess production of thyroid hormones, which can speed up the body's metabolism. Common symptoms include weight loss, rapid heartbeat, and anxiety. It can also cause bulging eyes, a condition known as Graves' ophthalmopathy. The exact cause of Graves' Disease is not fully understood, but it is believed to involve a combination of genetic and environmental factors. Treatment options often include medications to control hormone levels, radioactive iodine therapy, or surgery to remove part of the thyroid gland. Early diagnosis and management can help alleviate symptoms and improve quality of life.
