Diets for hyperthyroid patients avoid iodine-rich foods and medications, such as kelp, nori, and amiodarone. Iodine-rich foods, such as kelp, nori, seafood, iodized salt, etc., should be avoided by hyperthyroid patients. Because the level of thyroid hormone in the body of patients with hyperthyroidism is higher than normal, iodine is the raw material for the synthesis of thyroid hormone, when consuming these foods with high iodine content, it will increase the synthesis of thyroid hormone, which is not conducive to the control of hyperthyroidism. In addition, hyperthyroid patients should also be careful to use drugs containing high iodine, such as amiodarone. In addition to paying special attention to their diets, people with hyperthyroidism should also follow the doctor’s instructions for standardized treatment.
