Gastric diversion surgery was first used in bariatric surgery, and then it was found that obese patients with type 2 diabetes had improved their diabetes symptoms after the surgery, and after several years of clinical practice, doctors accidentally found that this surgery could effectively treat diabetes, thus gastric diversion surgery brought a new gospel for diabetic patients. When it comes to the surgery, the first issue that everyone considers is the safety and whether there will be any side effects after the surgery. The principle of gastric diversion surgery: The unique feature of gastric diversion surgery is that the physiological flow of food is changed through gastric blockage, gastrointestinal anastomosis and intestinal anastomosis. After the surgery, the 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 islet function, and cures diabetes. In addition to the normalization of blood sugar, the patient recovered well from a series of accompanying complications. For example, retinopathy, diabetic nephropathy, diabetic dermatitis, diabetic sexual dysfunction, hypertension, hyperlipidemia, etc. were gradually cured. The occurrence of serious complications has been eliminated, and the occurrence of disabling and fatal situations has been avoided. What is the effect of gastric diversion weight reduction surgery? First, effective treatment of diabetes, normal blood sugar, patients get rid of lifelong medication and do not need to control diet. There are two main reasons for the development of diabetes: one is insulin resistance. The second is islet failure. After gastric diversion surgery, insulin resistance is gone, islet function is restored, and diabetes is gone. Second, the diabetic complications get recovered. Internal medicine cannot reverse the complications that have occurred in patients. After gastric diversion surgery, most patients gradually recover from diabetic complications such as hand and foot numbness, retinopathy, diabetic foot, abnormal urine protein, and hypertension, etc. Third, avoid the occurrence of disability and death caused by diabetes. The development of diabetes to a serious degree can pose a serious threat to a person’s life safety. After gastric diversion surgery, blood sugar is normal, complications no longer appear, and the danger of diabetes is gone. Fourth, obese patients lose weight and thinner patients gain weight. 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. V. Reduce the financial burden of patients. 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 have 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. Six gastric diversion surgery has low risk and fast recovery after surgery. The surgery is easy and quick, with little trauma, quick recovery, 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.
