E01: Iodine-deficiency-related thyroid disorders and allied conditions
E01.1: Iodine-deficiency-related multinodular (endemic) goitre
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. More thyroid gland tissue then grows in order to compensate. This makes the thyroid gland larger. In addition, several nodules have formed in your thyroid gland. Thyroid gland nodules like these can form when the thyroid gland tissue thickens.
You can possibly feel, or even see, an enlarged thyroid gland. A seriously enlarged thyroid gland can cause problems with swallowing or breathing.
