In March 2011, at the 2nd International Conference on Interventional Treatment of Type 2 Diabetes, the International Diabetes Federation (IDF) issued a statement recognizing bariatric surgery as one of the therapeutic measures for the treatment of type 2 diabetes and recommending that among patients eligible for bariatric surgery, early consideration should be given to the use of surgical methods to help prevent possible complications. The statement was written by 20 leading experts in the field of diabetes and bariatric surgery from the International Diabetes Federation’s (IDF) Epidemiology and Prevention Working Group, including Chinese diabetes expert Professor Ji Linong. Obesity combined with type 2 diabetes will be the most serious epidemic and public health problem in human history. type 2 diabetes is one of the fastest growing diseases, with 300 million people living with the disease to date, and is expected to grow to 450 million by 2030. There is growing evidence that glycemic control and other obesity-related comorbidities in obese patients with type 2 diabetes can be significantly improved following bariatric surgery. Almost all severely obese patients have difficulty achieving and maintaining significant weight loss, and bariatric surgery can lead to remission in up to 80% of diabetic patients. Therefore, experts believe that “bariatric surgery intervention for obese type 2 diabetic patients is a healthy, cost-effective option with an acceptable safety profile. Bariatric surgery should be considered early for severely obese type 2 diabetic patients, rather than a remedy that is put off until the last resort.” Patients with type 2 diabetes with a BMI ≥ 35 should be considered for surgical options. Surgical treatment should be performed strictly within the limits of accepted guidelines and require a reasonable preoperative multidisciplinary evaluation as well as ongoing follow-up. And for Asian populations at increasing risk for diabetes and heart disease, the weight cut point for elective surgery may be lower.
