After more than 20 years of dedicated research and clinical practice in the field of diabetes medicine, gastric diversion surgery has developed into a mature treatment for diabetes and the only clinical cure for type 2 diabetes. In the United States, the American Diabetes Association (ADA), the world’s leading authority on diabetes treatment, has officially included gastric diversion surgery (GBP) in the Guidelines for the Prevention and Treatment of Diabetes, identifying it as a routine treatment for diabetes. 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. Advantages of Gastric Diversion Surgery: Advantage 1: Cure diabetes, normal blood sugar, patients get rid of lifelong medication and do not need to control their diet. There are two main causes for the development of diabetes: one is insulin resistance. The second is the failure of pancreatic islet function. After gastric diversion surgery, insulin resistance is gone, islet function is restored, and diabetes is gone. Advantage 2: Diabetic complications are recovered. While internal medicine cannot reverse the complications that have occurred in patients, after gastric diversion surgery, most patients gradually recover from diabetic complications such as numbness in hands and feet, retinopathy, diabetic foot, abnormal urine protein, and hypertension. Advantage 3: Avoid the occurrence of disabling and fatal conditions caused by diabetes. When diabetes develops to a serious level, it can pose a serious threat to a person’s life safety. After gastric diversion surgery, blood sugar is normal, complications no longer occur, and the danger of diabetes is gone. Advantage 4: Weight loss in obese patients and weight gain in thinner patients. Gastric diversion surgery can bring some unexpected effects to patients, very thin patients will gain weight after surgery, and very fat patients achieve satisfactory weight loss after surgery. Advantage 5: Reduce the financial burden of the patient. The relative cost is not high, which is the obvious advantage of gastric diversion surgery. According to the survey, most diabetic patients who have been ill for more than 5 years will develop various complications, and the treatment of these complications is very expensive. For diabetic patients, a single surgical treatment, complications no longer appear and the financial burden is reduced. Advantage 6: Gastric diversion surgery has low risk and fast recovery after surgery. The surgery is easy and quick, with little trauma, quick recovery and no recurrence, and you can eat in 3 days after surgery and be discharged in a week. Post-operative diet and nutrition absorption are not affected. At the beginning, because she was afraid of her parents’ worry, Ms. Tong hid the surgery from them. One month after the operation, when she came to her parents, they saw that she was concealed and only then did they know that she had undergone gastric diversion surgery and that her blood sugar and blood pressure had returned to normal indicators without the need for medication, and that her diabetes, fatty liver and hypertension had been greatly relieved.
