Hyperthyroidism is short for hyperthyroidism. Hyperthyroidism may be cured. Hyperthyroidism usually needs to be treated by antithyroid drugs, radioactive iodine and surgery. 1. Antithyroid drugs include thiourea drugs (e.g., propylthiouracil, methylthiouracil), and imidazole drugs (e.g., carbimazole, methimazole). The mechanism of action of antithyroid drugs is to inhibit the organicization of iodine and the coupling of thyroid tyrosine, reducing the synthesis of thyroid hormones. 2. The mechanism of radioactive iodine therapy is that iodine 131 releases β-rays in the process of decay, and β-rays have strong ionizing radiation ability, which can make part of thyroid follicular cell degeneration and necrosis, and the synthesis and secretion of thyroid hormone decrease, and the volume of thyroid gland shrinks, so as to achieve the purpose of treating hyperthyroidism. 3. There is a possibility of recurrence after anti-thyroid drugs and radioactive iodine treatment. Surgery has a high cure rate for hyperthyroidism, and the recurrence rate after total resection is almost zero. Patients with hyperthyroidism should consult a specialized doctor for diagnosis and treatment.
