Metabolism of Iodine
ОглавлениеIodine is readily absorbed via the entire length of the intestinal tract. Malabsorption of iodine is not known, even by those with other malabsorption syndromes. At any given point, the body of an adult will contain 15-20 mg of iodine, mostly within the thyroid gland. The kidneys are unable to conserve iodine, thus most plasma iodine not taken up by the thyroid or other tissues is lost in the urine. Lesser variable amounts are also lost in feces, sweat, saliva, and breast milk. The proportions of iodine lost by different routes is variable between and within individual subjects.8
Although iodine deficiency is the most common cause for hypothyroidism globally, nearly all cases of hypothyroidism in the industrialized world are secondary to autoimmune disease.
