What Causes an Enlarged Thyroid?


What are the causes of an enlarged thyroid?


An enlarged thyroid is called goiter. There are many possible causes of the disease. In some remote mountainous parts of the world, people have an enlarged thyroid mainly because of a lack of iodine. Autoimmune disorders can also lead to an enlarged thyroid, such as Grave’s disease and Hashimoto’s thyroiditis. Besides, people with bipolar disorder, taking the drug lithium carbonate (Priadel), may get a goiter due to the medication.

In teenagers and young adults who have a goiter, the lump is evenly or diffusely enlarged. After years of development, the condition will be more complex. The thyroid may be full of lumps or multiple nodules. When the patient reaches his middle age, he may have a multinodular goiter.
