Iodine in biology hormone is suppressed, the body simply eliminates excess iodine, and as a result, long-term supplementation with high doses of iodine has no additional effect once the body is replete with enough iodine. It is unknown if the thyroid gland is the rate-limiting factor in generating thyroid hormone from iodine and tyrosine, but assuming it is not, a short-term loading dose of one or two weeks at the tolerable upper intake level may quickly restore thyroid function in iodine-deficient patients. Iodine vapor is very irritating to the eye, to mucous membranes, and in the respiratory tract. Concentration of iodine in the
Adrenal gland disorder Adrenal gland disorder Adrenal gland disorders (or diseases) are conditions that interfere with the normal functioning of the adrenal glands. Adrenal disorders may cause hyperfunction or hypofunction, and may be congenital or acquired. The adrenal gland produces hormones that affects growth, development and stress, and also helps to regulate kidney function.
