Protrusion of the eyeballs (exophthalmos) and weight loss are common features of hyperthyroidism, a condition where the thyroid gland produces excessive thyroid hormones. Exophthalmos is often associated with Graves' disease, an autoimmune disorder. Increased metabolic rate from excess thyroid hormones can cause weight loss despite increased appetite. Other symptoms may include increased heart rate, nervousness, and fatigue.
