Hyperthyroidism can be cured with iodine-131. The above treatment is widely used in clinical practice and has shown good efficacy. It is generally administered orally, allowing iodine-131 to enter the patient's body and selectively accumulate in thyroid tissue. Through continuous low-dose radiation to the thyroid, part of the thyroid tissue is destroyed, achieving a therapeutic effect. Many hyperthyroid patients can be cured after radioactive iodine-131 treatment. However, hypothyroidism may occur as a potential side effect.
