Graves' disease is an autoimmune condition where your immune system produces antibodies that cause the thyroid to produce too much thyroid hormone. 'Star Wars' star Daisy Ridley and rapper Missy Elliot both have the condition, which about 80% of people with an overactive thyroid gland also have. The condition gets its name from the Irish surgeon who first described it in the early 19th century, Sir Robert Graves. Modern medicine has come a long way since its discovery, and there are treatments today that can
help people diagnosed with the condition.
