What is hyperthyroidism?

Hyperthyroidism, or overactive thyroid disease, means your thyroid gland makes and releases too much thyroid hormone. The thyroid gland is located in the front of your neck, just below your Adam’s apple. It makes hormones that control your metabolism. Metabolism is the pace of your body’s processes and includes things like your heart rate and how quickly you burn calories.

Hyperthyroidism can affect your metabolism. It can also cause nervousness, increased perspiration (sweatiness), rapid heartbeat, hand tremors, difficulty sleeping and weight loss.
