Goiter, or enlargement of the thyroid gland, is usually the earliest
visible symptom of iodine deficiency. (Goiter can occur for many other
reasons as well, but iodine deficiency is among the most common causes
worldwide.) The enlargement of the thyroid results from overstimulation
of the thyroid gland by thyroid stimulating hormone (TSH), as the body
attempts to produce increased amounts of thyroid hormone.Goiter is more common in certain geographical areas of the
world where iodine is lacking in the diet and where selenium is lacking
in the soil. (Selenium is directly involved with certain activities of
the thyroid gland.)
