Hyperthyroidism

Alternative Names:

Thyrotoxicosis; Overactive thyroid

Treatment:

Treatment varies depending on the cause of the condition and the severity of symptoms. Hyperthyroidism is usually treated with antithyroid medications, radioactive iodine (which destroys the thyroid and stops the excess production of hormones), or surgery to remove the thyroid.

If the thyroid must be removed with radiation or surgery, replacement thyroid hormones must be taken for the rest of the person's life.

Beta-blockers like propranolol are used to treat some of the symptoms including rapid heart rate, sweating, and anxiety until the hyperthyroidism can be controlled.

Expectations (prognosis):

Hyperthyroidism caused by Graves disease is usually progressive and has many associated complications, some of which are severe and affect quality of life.

These include complications caused by treatment such as use of radioactive iodine, surgery, and medications to replace thyroid hormones. However, hyperthyroidism is generally treatable and rarely fatal.

Complications:

Calling your health care provider:

Call your health care provider if you have symptoms which could be caused by excessive thyroid hormone production. If the symptoms are associated with a rapid, irregular heartbeat, dizziness, or change in consciousness, go to the emergency room or call the local emergency number (such as 911).

Call your health care provider if treatment for hyperthyroidism induces symptoms of under-active thyroid, including mental and physical sluggishness, weight gain, and depression.
