hyperthyroidGraves’ disease is an autoimmune condition; it is due to the immune system attacking the thyroid. This causes an overproduction of thyroid hormone. Graves’ disease is the most common cause of hyperthyroidism. Symptoms may include irritability, anxiety, trouble sleeping, rapid heartbeat, weight loss, increased perspiration, sensitivity to heat, a fine tremor in the hands or fingers and weight loss. The patient may also experience more frequent bowel movements, women may notice a change in the menstrual cycle and the thyroid gland may become enlarged.

One common symptom is exopthalmos, or a “bulging” of the eyes. It is also known as Graves’ ophthalmopathy. It is possible for the eyes to be dry, there may be a sensation of “grit” in the eyes. The eyes may also become red or inflamed and sensitive to light. The eyes may also become watery. If the condition becomes severe ulcers may form on the cornea, eye movements may become limited and vision may be affected (blurred, double vision or reduced vision). Smokers are much more likely to develop Graves’ ophthalmopathy than non smokers.
