Surgery for type 2 diabetes has actually been written into the diabetes treatment guidelines for a long time, and in foreign countries it was even written into the guidelines of internal medicine 10 years ago.

There are often people who are afraid of surgery and worried about the safety of surgery, but in fact, this surgery is already very safe in mature centers, and there are no serious complications in our Jiangsu Provincial People’s Hospital Bariatric Center until now, and the recovery is smooth, and we can be discharged from the hospital after 3 days. Some people worry about malnutrition after surgery, but in fact, patients can adjust themselves to overweight or normal weight after surgery, and if you follow the instructions of the medical staff, there will be almost no long-term complications during regular follow-up. Quantitative vitamin and iron supplements, etc. In fact, the complications after surgery are almost minimal compared to the complications of diabetes, just like we have patients who are already blind or have bad kidney function before regretting that they have islet cell failure and often lose the opportunity to have surgery. Surgery for type 2 diabetes is not a myth, nor is it suitable for all doctors or all patients. The Chinese Society of Bariatric and Diabetic Surgeons (CSMBS) calls on patients to go to larger hospitals for surgery, as well as to centers of excellence, for better safety and results.
