E01.8: Other iodine-deficiency-related thyroid disorders and allied conditions

The thyroid is a small organ at the bottom of the neck. The thyroid gland needs iodine to produce important messenger substances for the body. These messenger substances influence the heartbeat, digestion, and body temperature, among other things.

One may lack iodine when there is too little iodine in one’s diet. When there is a lack of iodine, the thyroid gland produces fewer messenger substances than usual.
