Patient: The patient is 73 years old and has been suffering from hyperthyroidism for 10 years. She has been on medication for 10 years, but this time her condition has relapsed and the Handan Central Hospital suggested transferring her to iodine therapy. Jia Hongli: It is better to choose 131I treatment because hyperthyroidism has a long history and drug treatment is ineffective and has no cure rate, and the side effects are large and the total recurrence can also cause serious complications such as hyperthyroid heart and heart failure.
