Gastric bypass surgery to reduce glucose: The unique feature of gastric bypass 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 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. Gastric bypass surgery was first used in bariatric surgery, and later it was found that obese patients with type 2 diabetes improved their diabetes symptoms after the surgery. So what are the sequelae of gastric bypass? Advantages of gastric bypass 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 of diabetes: one is insulin resistance. The second is the failure of pancreatic islet function. After gastric bypass surgery, insulin resistance is gone, pancreatic islet function is restored, and diabetes is gone. Advantage 2: Diabetic complications are rehabilitated. While internal medicine cannot reverse the complications that have occurred in patients, after gastric bypass 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 bypass 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 bypass surgery can bring some unexpected results to patients, with very thin patients gaining weight after surgery and very fat patients achieving satisfactory weight loss after surgery. What are the after-effects of gastric bypass surgery? Gastric bypass surgery has a nutritional absorption disorder, but the nutritional elements can be supplemented by post-surgical dietary guidance. It is necessary to take multivitamins, calcium tablets, and trace elements every day in order to prevent symptoms such as osteoporosis, hair loss, and dry skin caused by vitamin deficiency.
