The tests done to diagnose hyperthyroidism are Iodine thyroid scan, Blood test and thyroid scan.
Treatment depends on the cause and the severity of symptoms. Hyperthyroidism is usually treated with one or more of the following: Antithyroid medications, Radioactive iodine to destroy the thyroid gland and stops the excess production of hormones and Surgery to remove the thyroid. If your thyroid is removed with surgery or destroyed with radiation, you must take thyroid hormone replacement pills for the rest of your life. Medicines called beta-blockers may be prescribed to treat symptoms such as fast heart rate, sweating, and anxiety until the hyperthyroidism can be controlled.
