In the United States, in January 2009 the American Diabetes Association (ADA), the world authority on diabetes treatment, officially included gastric diversion surgery (GBP) in the Diabetes Prevention and Control Guidelines, establishing it as a routine treatment for diabetes. The 44th European Diabetes Association (October 2008. Rome, Italy) concluded that type 2 diabetes is expected to be a surgically curable gastrointestinal disease. In Europe, the 45th Annual Meeting of the European Diabetes Research Society on September 29, 2009 confirmed that diabetes has become a surgically curable gastrointestinal disease. In China, the Chinese Medical Association, the Chinese Medical Association, the Chinese Medical Continuing Education Center and other authorities have made gastric diversion surgery a key promotion project for three consecutive years. What is meant by gastric diversion surgery treatment? Gastric diversion surgery was first used in bariatric surgery. Westerners have been consuming high fat and high calories for a long time and their weight has been rising, many people accept this kind of bariatric surgery in order to pursue beauty and make themselves healthy again. After several years of clinical practice, doctors accidentally found that this kind of surgery can effectively treat diabetes, thus gastric diversion surgery, which brings a new gospel for diabetic patients. The reason why gastric diversion surgery can treat diabetes in one go and achieve clinical cure is that the unique feature of gastric diversion surgery is that it changes the physiological flow of food, which is accomplished through the steps of gastric blockage, gastrointestinal anastomosis and entero-intestinal anastomosis. After the surgery, insulin resistance in the patient’s body is eliminated, and the way food flows through the body after the surgery also promotes insulin secretion in the patient’s body, reduces apoptosis and proliferation of islet cells, restores the function of the pancreas, and cures diabetes.
