Summer, for some people, may be the sun, the beach and bikinis; others will say it is the pink memories, leaving little secrets; some friends think it is the summer light years, indulge in recklessness and splash. But for our fat friends, it is sweating, sweating, sweating non-stop! Worse, it’s heat rash, dermatitis and the smell of sweat emanating from your body! So what do you know about surgical weight loss? Bariatric surgery after-effects? What are the bariatric surgeries? Bariatric surgery “sleeve gastrectomy” method: in the direction of the large curve of the stomach to retain 2-6cm above the pylorus sinus, along the long axis of the stomach to remove the large part of the stomach, remove all the gastric fundus, so that the residual stomach is “banana-shaped”, the volume of about 60-80ml The volume of the remaining stomach is about 60-80ml. 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 Eurocup. Laparoscopic gastric reduction surgery, also known as sleeve gastrectomy, is quite a hot topic in the bariatric surgery medical community, and its popularity has increased significantly. Gastric reduction surgery works by using a laparoscope to cut out the greater curvature of the stomach vertically, creating a small stomach sac of about 150cc, which can hold about 4-5 ounces of food. The benefit is that it does not require the placement of foreign objects in the body and the procedure is highly effective for weight loss. Because 80% of the volume of the stomach is cut off during the surgery, in addition to reducing the amount of food eaten, the appetite stimulating hormone Ghrelin is also reduced, thus reducing the appetite. Within two years after surgery, you can lose about 10-15 BMI or 70% of your excess weight. For those who have a high BMI (over 40) and have difficulty reducing their appetite, gastric reduction surgery can achieve the desired weight loss. Although this surgery can help patients to reduce their food intake significantly, weight loss does not necessarily occur naturally after surgery. Therefore, no matter which kind of bariatric surgery has been performed, patients still need to pay attention to diet and maintain exercise in order to have ideal obesity treatment results. Because of the stomach reduction surgery, the diet must also be carried out in a gradual manner. The basic principle is the same as the diet after gastric bypass surgery. As for high-calorie drinks, they should be avoided completely. In order to avoid unsatisfactory weight loss. The three meals should be regular and balanced. Bariatric surgery “gastric bypass” Method: On the one hand, a small gastric bursa is built in the upper part of the stomach to limit food intake, and on the other hand, a small gastric bursa anastomosis is made in the distal hollow area to bypass the large part of the stomach, duodenum and the first jejunum, thus greatly controlling food intake and absorption. Principle: Changing the intestinal structure, shutting down most of the gastric functions, reducing the space of the stomach and the length of the small intestine. Advantages: Significant weight reduction and treatment effects can be expected to be maintained over time. Gastric bypass surgery refers to a series of similar surgical procedures used to treat obesity. The common features are: the surgery first divides the stomach into two parts, the smaller upper part and the larger lower part, and then truncates the small intestine, rearranges the position of the small intestine, changes the pathway of food through the digestive tract, and slows down the absorption of food. the digestive tract, slowing gastric emptying, shortening the small intestine, and decreasing absorption. Surgeons have developed several different alignment options that form several branches of gastric bypass surgery. According to 2008 data from the National Center for Health, gastric bypass surgery has replaced gastric reduction surgery as the most popular bariatric procedure in the United States after 2000, with approximately 100,000 cases performed each year. Disadvantage one: changes in the gastrointestinal digestive tract, the large gastric sac in the open can no longer be examined by gastroscopy, but only by CT and other examinations or probed under laparoscopy, which needs to be carefully considered for patients with a family history of gastric cancer or recurrent gastric ulcers. Disadvantage 2: The operation is relatively complicated and requires high technical level of doctors and laparoscopic skills, so not all doctors are suitable for the operation. Disadvantage 3: Vitamin and mineral supplements are needed during the postoperative recovery period, and patients are advised to take multivitamins regularly, especially iron, calcium, etc.
