Treatment of this condition is surgery to remove the nodules that are producing too much thyroid hormones. Radioactive iodine can be given to shrink the nodules that are making too much thyroid hormones. Medications such as methimazole could be prescribed to slow down the thyroid glands from producing too much of the thyroid hormones. This medication is usually taken three times a day (every 8 hours) with food 3. The mechanism of this drug is to inhibit the oxidation of iodine in the thyroid gland, thus this will inhibit the synthesis of T3; however, this is not affecting the circulating T3 and T4 4.
Another problem of the thyroid is called hypo-secretion. This occurs when the thyroid gland isn’t making enough thyroid hormones. This is a condition that is not as common in the United States because iodine is added in the salt 6. Although tumors may cause hypersecretion of thyroid hormones, but sometimes, they could cause the glands to reduce the amount of secretion of the hormones. This is due to the competition of blood supply to feed the tumors causing lack of blood supply to the glands, resulting under secretion of the hormones. Tumors could also cause
