Excessive Iodine Intake Does Not Increase the Recurrence Rate of Graves Disease after Withdrawal of the Antithyroid Drug in an Iodine-Replete Area

摘要

Background and ObjectivesThe relationship between iodine intake and effects of antithyroid drugs (ATD) for Graves' disease, especially in iodine-deficient areas, has been demonstrated in many studies. However, it was not clear how chronic high iodine intake influenced the effectiveness of ATD in an iodine-replete area. This study aimed to clarify the effect of iodine intake on clinical outcomes of Graves' disease after discontinuation of ATD in Korea, an iodine-replete area.
