If the traditional method does not work for a long time, Director Dai Xiaojiang recommends doing stomach reduction surgery for weight loss. In fact, surgical weight loss in Western Europe and the United States and other countries has been developed for half a century and has become a mainstream method of weight reduction. Here is a small introduction to the indications for gastric reduction surgery! The principle of gastric reduction surgery: Gastric reduction surgery is a kind of weight reduction surgery. The effect of gastric reduction surgery is somewhere between gastric bypass and gastric banding. The full procedure takes only about 1 hour and is less invasive, quicker to recover and less risky. Gastric reduction surgery is performed by using a laparoscope to cut out the large curvature of the stomach vertically to create a small stomach sac of about 150cc, which can hold about 4-5 ounces of food, thus reducing the amount of appetite hormones produced to reduce the patient’s appetite. At the same time change the flow of food, no longer through the lower part of the stomach and duodenum, by rerouting to change the body’s absorption of nutrients, so as to improve or cure obesity, in order to avoid obesity to bring more harm to their lives and health. By rerouting the upper part of the stomach and rearranging the position of the small intestine, the intake of food is reduced and the absorption of calories by the small intestine is reduced, thus achieving weight loss in a two-pronged way. At the same time, the medical community has found that the increased speed of food entering the intestines after surgery can help cure type 2 diabetes. For obese patients suffering from type 2 diabetes, it is the most suitable. Indications for gastric reduction surgery: 1. Those who have tried exercise therapy, diet control, medication, Chinese herbal medicine and food therapy and other non-surgical methods, but have failed. 2. If the body mass index BMI is greater than 27.5 and there are serious complications, such as hyperglycemia, hypertension, hyperlipidemia and other metabolic diseases, because the body state is already “morbidly obese”, weight reduction surgery can be considered to relieve obesity. 3. Patients between 16 and 65 years of age who also meet the requirements of (1) and (2) above can undergo weight reduction surgery.
