The most common form of thyroid disease is the enlargement of the thyroid gland, called the struma, also known as goiter. One of the possible, and at the same time most objectionable, cause of its development is the low iodine consumption. For adults, 150 micrograms of iodine per day is needed for the proper functioning of the thyroid gland.
In addition to the visible signs, other symptoms may also be associated with thyroid disease.
