Patients with hyperthyroidism are advised to avoid iodized salt. Hyperthyroidism is an endocrine disease caused by excessive thyroid hormone hypermetabolism, and iodine is the raw material for synthesizing thyroid hormone, so patients with hyperthyroidism are advised to avoid consuming iodized salt and try to replace it with non-iodized salt, as well as not to eat iodine-rich foods, such as kelp, nori, and so on. Patients with hyperthyroidism are advised to follow the doctor’s instructions for treatment, which may include oral antithyroid drugs, iodine 131 treatment or surgery. Daily diet is recommended to provide high-energy, high-protein, high-vitamin diets to compensate for its consumption and improve the general nutritional status. Appropriate restriction of foods containing much dietary fiber is recommended to reduce the occurrence of diarrhea. Patients diagnosed with hyperthyroidism should actively cooperate with doctors for treatment.
