The thyroid gland may fail toproduce sufficient thyroid hormones to meet the body requirementshence causing the enlargement of the thyroids. This is due toinsufficient iodine in the diet (Lloyd, 2010). Other factors leadingto this condition include infections and cigarette smoking.

Theother kind of is the Toxic nodular goiter. This is an enlargedthyroid gland with growths called nodules that produce excess thyroidglands. Thyroxin (T-4) and triodothyronine are the thyroid glandsthat help regulate metabolism in people’s bodies. Over time,hypothyroidism condition can occur where the gland stops producingenough thyroid hormone. Sometimes the goiter becomes toxic producinghigh levels of thyroid hormone thus causing a hyperthyroidismcondition (Lloyd, 2010). The main symptom is an enlarged thyroidgland. This sometimes affects the trachea and can lead to breathingproblems, cough and swallowing difficulties.

Duringgoiter testing, the doctor does a physical examination that involvesfeeling one`s neck and thyroid area while swallowing. Hormone testsare conducted using blood samples to measure the thyroid functions.Thyroid scan and ultrasonography of the thyroid are conducted toestablish possibilities of cancer and any other abnormalities.

Asimple goiter should only be treated if it is causing visiblesymptoms. Using iodized table salt helps prevent this condition(Lloyd, 2010). Seafood, locally grown vegetables, as well as fruits,contain iodine that is essential in the. The treatments for toxicnodular goiter include surgery to remove the gland, using pills toreplace the thyroid hormone, doses of potassium iodine and the use ofradioactive iodine that helps shrink the gland.

Oneneeds approximately 150 micrograms of iodine per day. Lactating andpregnant women need adequate iodine in their diets. Althoughuncommon, too much iodine can cause goiter. One should consult amedical profession once he or she experiences any swelling on theneck or any of the goiter symptoms (Lloyd, 2010).
