Treatment
The major and generally accepted modalities for treatment of hyperthyroidism in humans are:
Surgery
Surgery (to remove the whole thyroid or a part of it) is not extensively used because most common forms of hyperthyroidism are quite effectively treated by the radioactive iodine method. However, some Graves' disease patients who cannot tolerate medicines for one reason or another or patients who refuse radioiodine opt for surgical intervention. Also, some surgeons believe that radioiodine treatment is unsafe in patients with unusually large gland, or those whose eyes have begun to bulge from their sockets, claiming that the massive dose of iodine needed will only exacerbate the patient's symptoms. The procedure is quite safe - some surgeons even perform partial thyroidectomies on an out-patient basis.
Radioiodine
In Iodine-131 (Radioiodine) Radioisotope Therapy, radioactive iodine is given orally (either by pill or liquid) on a one-time basis to destroy the function of a hyperactive gland. The iodine given for ablative treatment is different from the iodine used in a scan. Radioactive iodine is given after a routine iodine scan, and uptake of the iodine is determined to confirm hyperthyroidism. The radioactive iodine is picked up by the active cells in the thyroid and destroys them. Since iodine is only picked up by thyroid cells, the destruction is local, and there are no widespread side effects with this therapy. Radioactive iodine ablation has been safely used for over 50 years, and the only major reasons for not using it are pregnancy and breast-feeding.
Often, due to the difficulty of picking the correct dose, the treatment results in an opposite condition - hypothyroidism. However, that is usually easily treated by the administration of levothyroxine, which is a pure synthetic form of T4.
Thyrostatics
Thyrostatics are drugs that inhibit the production of thyroid hormones, such as methimazole (Tapazole®) or PTU (propylthiouracil). Thyrostatics are believed to work by inhibiting the iodination of thyroglobulin by thyroperoxidase.
If too high a dose is used in pharmacological treatment, patients can develop symptoms of hypothyroidism. Hypothyroidism is also a very common result of surgery or radiation treatment as it is difficult to gauge how much of the thyroid gland should be removed. Supplementation with levothyroxine may be required in these cases.
Beta-blockers
Beta blockers do not treat, but rather mask, common symptoms of hyperthyroidism such as palpitations, trembling, and anxiety. Metoprolol is most frequently used to augment treatment for hyperthyroid patients.

Hyperthyroidism is a condition in which an overactive thyroid gland is producing an excessive amount of thyroid hormones that circulate in the blood. ("Hyper" means "over" in Greek). Thyrotoxicosis is a toxic condition that is caused by an excess of thyroid hormones.
If you are concerned that you may have an excess amount of thyroid hormone, you should mention your symptoms to your doctor. A simple blood test is the first step in the diagnosis. From there, both you and your doctor can decide what the next step should be. If treatment is warranted, it is important for you to let your doctor know of any concerns or questions you have about the options available. Remember that thyroid disease is very common, and in good hands, the diseases that cause an excess of thyroid hormones can be easily diagnosed and treated.

SEEK MEDICAL HELP, CONFIRM IF U HAVE TOO MUCH IODINE (LAB TESTS). IF U HAVE HYPERTHYROIDISM, AVOID FOODS RICH IN IODINE, LIKE CABBAGES, SEAFOODS AND IODIZED SALT.
TAKE THE MEDICINES THAT WOULD NORMALIZE THE IODINE IN UR BODY, THEN HAVE THE MAJOR TREATMENT, SURGICAL OR THE RADIO ACTIVE IODINE INTAKE.
