Iodine-induced hyperthyroidism

Iodine-induced hyperthyroidism (IIH) refers to hyperthyroidism related to increased iodine intake, referred to as iodine hyperthyroidism, also known as iodine-induced thyrotoxicosis (IIT). Judging from the amount of iodine intake, there are three cases of iodine hyperthyroidism: the first is that one or more large doses of iodine cause iodine hyperthyroidism, such as taking iodine-containing drugs such as amiodarone or using contrast agents It can occur in people with normal iodine nutrition, and those who suffer from nodular thyroiditis are more likely to occur. The second type is the intake of higher doses of iodine, which mostly occur in areas with high iodine. Hyperthyroidism; the third is a general dose of iodine (which can be the iodine intake in the physiological range), seen in patients with iodine deficiency areas (including marginal iodine deficiency areas) after taking iodized salt; non-iodine deficiency areas Patients take iodine; patients with original hyperthyroidism have relapsed after taking iodine.
