Iodine allergy and thyroid gland – how are they related?
In the thyroid gland, iodine is absorbed from the blood and the cells of the thyroid gland are fed. There a chemical reaction takes place which causes the iodine to be incorporated into the thyroid hormone. This is then stored in the thyroid gland until it is used. If a signal now reaches the thyroid gland that thyroid hormone is needed in the body, the thyroid gland releases hormone, including iodine.
