Routine tests are: 1. Measurement of serum thyroid hormones (TT3, TT4, TSH, FT3, FT4) and TGAb, TMAb, TG. 2. Measurement of iodine uptake by the thyroid gland. 3.Thyroid nuclide imaging. 4. Routine blood, liver function, kidney function, electrolytes, electrocardiogram, thyroid ultrasound, chest X-ray, etc. The choice of treatment for hyperthyroidism: 1) Internal anti-hyperthyroidism medication 2) Surgical treatment 3) Isotope 131-iodine treatment Liao Ning, Department of Hyperthyroidism, Second Affiliated Hospital of Guangxi University of Science and Technology All three types of treatment are effective, but surgical operation is more traumatic and risky; internal anti-hyperthyroidism medication is the most widely used, but it can only achieve a cure rate of 30%-40%, and the recurrence rate of hyperthyroidism after stopping medication is very high. The recurrence rate of hyperthyroidism is very high after stopping the medication. The most common side effects are leukopenia, liver function damage, and the most serious and life-threatening one is granulocyte deficiency. The cure rate of 131-iodine treatment for hyperthyroidism is positively correlated with the dose of 131-iodine treatment. The cure rate of 131-iodine treatment is positively correlated with the dose of 131-iodine treatment. The overall cure rate is over 80%, the failure rate is 2% to 4%, and the relapse rate is 1% to 4%. The best results are achieved in patients with diffuse goiter with moderate hyperthyroidism.
