Even when it's enlarged, your thyroid may produce normal amounts of hormones. It might also, however, produce too much or too little thyroxine and T-3. A number of factors can cause your thyroid gland to enlarge.Among the most common are: Iodine deficiency. Iodine, which is essential for the production of thyroid hormones, is found primarily in seawater and in the soil in coastal areas. Cancer of the thyroid often appears as an enlargement on one side of the thyroid. 2  Pregnancy. 3  A hormone produced during pregnancy, human chorionic gonadotropin (HCG), may cause your thyroid gland to enlarge slightly. 4  Inflammation.
1 Often, solid components are mixed with fluid in thyroid cysts. 2  Cysts are usually benign, but they occasionally contain malignant solid components. 3  Chronic inflammation of the thyroid (thyroiditis). 4  Hashimoto's disease, a thyroid disorder, can cause thyroid inflammation resulting in nodular enlargement. Goiter is a term used to describe any enlargement of the thyroid gland, which can be caused by iodine deficiency or a thyroid disorder. 2  A multinodular goiter contains multiple distinct nodules within the goiter, but its cause is less clear. 3  Thyroid cancer.
