The surgical treatment of diabetes has been widely agreed upon by the medical and surgical community. Is it good? Gastric diversion surgery: The causes of diabetes: First, K cells distributed in the gastrointestinal tract are stimulated by food to secrete insulin resistance factors, causing the body to develop insulin resistance. Second, the islet cells are damaged and apoptotic under the action of insulin resistance factor. 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 enteroenteric anastomosis. After the surgery, the insulin resistance in the patient’s body is eliminated, and the way the food flows through 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. Advantages of surgery: Advantage 1: Cure diabetes, normal blood sugar, patients get rid of lifelong medication and do not need to control diet. There are two main causes 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 hand and foot numbness, 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 gain weight after surgery, and very fat patients achieve satisfactory weight loss after surgery.
