The cause of hyperthyroidism is not clear, but it is related to emotional changes and changes in the living environment. Patients with hyperthyroidism usually have symptoms such as thickening of the neck and protruding eyes. Patients with hyperthyroidism also have symptoms of high metabolism, such as rapid heart rate, fear of heat, weight loss, and bad temper. The timing of surgery for hyperthyroidism is as follows: 1. moderate or severe hyperthyroidism with ineffective long-term medication or poor results; 2. relapse of hyperthyroidism after stopping medication with a large thyroid gland; 3. nodular goiter with hyperthyroidism; 4. obvious enlargement of the thyroid gland (R80g) with pressure on surrounding organs or post-thoracic goiter; 5. suspected coexistence with thyroid cancer; 6. children with poor results from anti-thyroid medication; 7. 8. Combined hyperparathyroidism requiring surgery; 9. Moderately active Graves’ ophthalmopathy. Partial thyroidectomy is one of the three methods for the etiological treatment of hyperthyroidism. Thyroidectomy has a high cure rate of about 95% for hyperthyroidism caused by Graves’ disease, and the recurrence rate is only 0.6%-9.8%.
