Graves' disease is an autoimmune disorder that causes the immune system to overstimulate the thyroid gland. It's one of the most common causes of hyperthyroidism.
The thyroid gland is a small, butterfly-shaped gland located in the base of the neck. Although relatively small, the thyroid gland plays a huge role in our body, influencing the function of many of the body’s most important organs.
