Sleeve stomach surgery works by using a laparoscope to cut out the greater curvature of the stomach vertically, creating a small stomach pouch 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 surgery is highly effective in weight loss. In addition to reducing the amount of food eaten, the procedure also reduces the amount of hormones that stimulate the appetite, 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 find it difficult to reduce the amount of food they eat, sleeve gastric surgery can achieve the desired weight loss results. Things to note after surgery: First of all, the patient’s eating habits will change considerably after surgery, and eating too much or too fast may cause nausea and vomiting. Some patients need a longer period of time to change their eating habits. The diet should be liquid for 2 weeks, soft food for 2-4 weeks and then solid food can be added slowly. Sometimes it may take 3-6 months to get used to it. Slight vomiting and gas are common. Food intake will gradually increase after 6 months. In about a year, you will feel full after eating half a sandwich and half a drink. It is important to realize that progress varies from person to person. Eat smaller and slower portions, and separate food and drinks as much as possible during meals. In addition, about 1/5 of the patients may have acid reflux after the surgery and may need medication. Generally, this condition will subside in 6-12 months. You should receive long-term dietary counseling from a dietitian for six months after surgery to avoid malnutrition. Hazards of Sleeve Gastric Surgery: After sleeve gastric surgery, the stomach and intestines do not absorb well, so it is necessary to take vitamin A supplements on a regular basis and return to the clinic regularly to follow up on the status of recovery.
