Can toxic goiter be prevented?

Dr. Jack Merendino, MD

Except in rare cases, toxic goiter cannot be prevented. Many toxic goiters are the result of a hereditary problem. In other cases we usually don’t know the cause. Sometimes a person who grew up in a area of the world with a very low iodine intake will develop what is called an “endemic goiter,” which means thyroid enlargement -- sometimes with nodules -- meant to compensate for the lack of iodine. On occasion, when such an individual moves to an area with normal or high iodine intake the nodules will begin to over-produce thyroid hormone, but this is not a common situation.  
Often, goiters are the result of things you cannot control, such as the level of your thyroid function and whether or not you have an auto-immune disorder. However, sometimes altering your diet can help. Goiters can grow due to a lack of iodine in the body, so be sure your iodine intake as at the right level. Iodine deficiency is rare in the U.S. and in places where salt is iodized.

A goiter is “toxic” if the thyroid nodule over-produces thyroid hormone. If you have a nontoxic goiter, monitor your symptoms in case the goiter becomes toxic, and follow your doctor's treatment recommendations.

Hormones are considered chemical messengers, coordinating your body by transferring information from one set of cells to another. Your endocrine system health can be affected by hormone imbalances resulting from impaired glands. A hormone imbalance can cause problems with bodily growth, sexual development, metabolism and other bodily functions. Endocrine system diseases or conditions include diabetes, growth disorders and osteoporosis.
