Understanding Hyperthyroidism

In hyperthyroidism, a hyperactive thyroid gland (an endocrine gland in the neck) secretes a greater than normal amount of thyroxine (thyroid hormone, or T4). Because thyroxine causes cells to burn fuel and release energy, signs and symptoms of hyperthyroidism are increased energy level and nervousness, tachycardia (increased heart rate), weight loss, and exophthalmos (bulging eyeballs).
