The present study examined the iodine diet in patients with hyperthyroidism. Hyperthyroidism is a serious disease that occurs due to dysfunction of the thyroid gland and increased production of thyroid hormone. This disease is usually treated with ant thyroid drugs and, if necessary, surgery. However, a healthy diet can also have a positive effect on improving the health of patients and their condition. For this reason, experts usually recommend that patients with hyperthyroidism follow a diet suitable for hyperthyroidism, along with other treatment options. The amount of radioactive iodine used to control thyroid diseases can vary depending on the individual's disease, so that in some diseases the dose can be without side effects. A proper diet can take steps to eliminate substances that aggravate the symptoms of hyperthyroidism and help improve the symptoms of the disease. A major problem in the diet of people with hyperthyroidism is controlling the amount of iodine intake. In some cases, doctors believe that the presence of excessive amounts of iodine can be effective in cases of hyperthyroidism, and therefore controlling the amount of iodine in the diet can help relieve the symptoms of the disease. The results showed that hyperthyroidism can cause obvious weight loss and make it difficult to gain weight. This is because the body's metabolism increases in this disease. The obvious connection between diet and hyperthyroidism is the presence of iodine in the diet. There are many reasons for the belief that iodine can increase the likelihood of developing hyperthyroidism. On the other hand, Graves' disease has an interesting connection with gluten. Diet can be useful for minimizing the damage caused by hyperthyroidism, especially brittle bones.
