Obesity due to excessive eating and reduced physical activity is the main environmental factor in type 2 diabetes, making individuals with a genetic susceptibility to type 2 diabetes susceptible to the disease. type 1 diabetes patients have an abnormal immune system that causes an autoimmune response after infection with certain viruses such as coxsackievirus, rubella virus, and mumps virus, which destroy insulin beta cells. What about the bariatric surgery “sleeve gastrectomy” to treat diabetes mellitus? Sleeve Gastrectomy: Laparoscopic gastric reduction surgery, also known as Laparoscopic SleeveGastrectomy, is a procedure that uses a laparoscope to cut out the large curve of the stomach vertically, creating a small stomach sac of about 150cc, which can hold about 4-5 ounces of food. It has the advantage of not requiring the placement of foreign objects in the body and the procedure is remarkably effective for weight loss. Method: 2-6 cm of the sinus above the pylorus is preserved in the direction of the greater curvature of the stomach, and the greater part of the stomach is removed along the long axis of the stomach, and the entire fundus is removed, leaving a “banana-shaped” stomach with a volume of about 60-80 ml. Principle: To reduce the volume of the stomach and decrease the secretion of hormones that stimulate the production of hunger. Advantages: It does not change the physiological state of the gastrointestinal tract and does not interfere with the normal process of digestion and absorption of food. Evaluation: Sleeve gastrectomy has good therapeutic effect on type 2 diabetes and is a widely used surgery for weight reduction and diabetes in Europe at present. Causes of diabetes: One, K cells distributed in the gastrointestinal tract are stimulated by food to secrete insulin resistance factor, which causes insulin resistance in the body. Second, islet cells are damaged and apoptotic under the action of insulin resistance factor. So what is the treatment of diabetes in the sleeve stomach? What is the principle? Let’s learn together! Principle of sleeve gastric surgery: The unique feature of sleeve gastric surgery is that the physiological flow of food is changed, which is accomplished through the steps of gastric block, gastrointestinal anastomosis and intestinal 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. 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 xing 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. Sleeve gastric surgery is less traumatic, low risk, fast recovery and no recurrence; most of the patients recovered normal blood glucose and stopped using hypoglycemic drugs and insulin before they were discharged from the hospital after surgery; a small number of patients have a slightly longer recovery time, which mainly depends on the extent of the patient’s preoperative islet function damage. Patients who are treated early will recover more quickly and completely. 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 the onset of diabetes: one is insulin resistance. The second is pancreatic islet failure. After sleeve gastric surgery, insulin resistance is gone, pancreatic 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 sleeve gastric 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 degree, it can pose a serious threat to a person’s life safety. After sleeve gastric surgery, blood sugar is normal, complications no longer occur, and the danger of diabetes is gone.
