What Is Hyperthyroidism?

Hyperthyroidism refers to the over-activity of the thyroid gland, resulting in too much thyroid hormone in the bloodstream. The over-secretion of thyroid hormone leads to over-activity of the body’s metabolism.

There are several forms of hyperthyroidism and symptoms include nervousness, irritability, increased perspiration, weak muscles, especially in the upper arms and thighs, shaky hands, fast heartburn, high blood pressure and weight loss.
