Hi, Graves disease is an autoimmune disorder that causes hyperthyroidism, which means that the thyroid gland produces too much thyroid hormone. Treatment for Graves disease aims to reduce the amount of thyroid hormone in the body, and there are several options available. Radioactive iodine (RAI) therapy is a common treatment for Graves disease. In this treatment, a small dose of radioactive iodine is given orally, which is absorbed by the thyroid gland. The radioactive iodine destroys the overactive thyroid cells, which leads to a reduction in the production of thyroid hormone. After RAI treatment, many people become hypothyroid, which means their thyroid gland does not produce enough thyroid hormone. In this case, treatment with thyroid hormone replacement therapy is necessary to replace the hormone that the thyroid gland is no longer producing. If your Graves disease has been treated with RAI and you are now hypothyroid and on thyroid hormone replacement therapy, your autoimmune disease can be considered to be in remission. However, it s important to continue monitoring your thyroid hormone levels and thyroid function regularly with blood tests, as there is a risk of recurrence of Graves disease even after successful RAI treatment. In addition to medical treatments, lifestyle changes can also help manage Graves disease symptoms. A healthy diet that includes plenty of fruits, vegetables, whole grains, and lean proteins can help support overall health. Stress reduction techniques, such as yoga, meditation, or deep breathing, can also be helpful. Regular exercise can also improve energy levels and help manage weight, which can be an issue for some people with Graves disease. It s important to work closely with your healthcare provider to manage your Graves disease and develop a comprehensive treatment plan that addresses all aspects of your health. Take care.
