Hyperthyroidism Test and Diagnosis

  • Hyperthyroidism
    Subclinical and overt hyperthyroidism is present in 1.6% and 1.3% of the Indian population according to one study. The equivalent number is 1% in an American population. Hyperthyroidism or thyrotoxicosis is an overactive thyroid where the thyroid gland produces too much of the thyroid hormones. Hyperthyroidism can accelerate your body's metabolism, causing unintentional weight loss and a rapid or irregular heartbeat.

    What is Hyperthyroidism The thyroid is an endocrine gland situated at the base of the neck.
