Some people may develop a goiter, which is an enlarged thyroid gland that feels like a swelling in the front of your neck. See more hyperthyroidism symptoms.

If your thyroid gland makes too much T4 and T3, this is defined as hyperthyroidism. In this disorder, the body makes an antibody a protein produced by the body to protect against a virus or bacteria called thyroid-stimulating immunoglobulin TSI that causes the thyroid gland to make too much thyroid hormone.
Hyperthyroidism also may be caused by a toxic nodular or A summary on hyperthyroidism goiter, which are lumps or nodules in the thyroid gland that cause the thyroid to produce excessive amounts of thyroid hormones. In addition, inflammation of the thyroid gland—called thyroiditis—resulting from a virus or a problem with the immune system may temporarily cause symptoms of hyperthyroidism.
Furthermore, some people who consume too much iodine either from foods or supplements or who take medications containing iodine such as amiodarone may cause the thyroid gland to overproduce thyroid hormones.
Finally, some women may develop hyperthyroidism during pregnancy or in the first year after giving birth. Diagnosis Hyperthyroidism is diagnosed based on symptoms, physical exam, and blood tests to measure levels of thyroid stimulating hormone TSH and thyroid hormones T3 and T4.
Treatment of Hyperthyroidism Hyperthyroidism can be treated with antithyroid medications that interfere with the production of thyroid hormones primarily methimazole; propylthiouracil is now used only for women in the first trimester of pregnancy.
Another option is radioactive iodine therapy to damage the cells that make thyroid hormones. In rare cases in which women do not respond to or have side effects from these therapies, surgery to remove the thyroid either one part of the entire gland may be necessary.
The choice of treatment will depend on the severity and underlying cause of your symptoms, your age, whether you are pregnant, other conditions you may have, and the potential side effects of the medication.

Hyperthyroidism is a disease in which the thyroid is hyperactive and makes too much thyroid hormone. Like most conditions of the thyroid gland, it is more common in women.
Hyperthyroidism can be caused by either overproduction of thyroid hormone or excessive release of thyroid hormone from the thyroid gland due to inflammation and/or destruction.
Untreated hyperthyroidism, particularly in older people, may result in cardiac arrhythmias, high-output cardiac failure, bone mineral loss, and, rarely, thyroid storm. Unusual complications include vision loss secondary to orbitopathy or elephantiasis secondary to dermopathy.
