Graves’ Disease or Thyroid Eye Disease

Graves' disease develops when the thyroid gland goes into overdrive and produces more hormones than the body requires. As a result, people with Graves' disease become very "hyper," and exhibit a variety of symptoms: weight loss despite increased appetite, irritability, heat intolerance, irregular heartbeats, and in women, changes in menstrual cycles. Overactive thyroid can also affect the eyes, creating bulging eyes, swelling, double vision and even loss of vision.
