Goiter is the disorder of the thyroid gland, it is a massive swelling and called as goiter. It is the result of the lack of iodine in the diet. The normal thyroid gland collects the iodine from the blood stream and is then synthesised to thyroxin. If there is lack of iodine, the thyroid gland enlarges and creates a goiter. This abnormal growth is stopped if iodine is given to the person.
