Sleeve gastric surgery – the stomach is removed longitudinally under laparoscopy to make the original enlarged stomach look like a banana, reducing the volume of the stomach and allowing for weight loss by eating less. So what are the post-sleeve gastric surgery complications? Compared to gastric bypass surgery, sleeve gastric surgery is simple and usually does not require vitamins after surgery. In terms of comparative results, gastric bypass surgery controls eating and absorption and results in greater weight loss than sleeve gastrectomy, which only focuses on controlling eating. Therefore, gastric bypass is more suitable for people with a BMI > 28 combined with type 2 diabetes; sleeve gastrectomy is more suitable for people with a BMI > 28 who are simply obese. What are the post-sleeve gastric surgery complications? Although this procedure is very safe, there are certain things to keep in mind. First of all, the patient’s eating habits may change considerably after surgery, and if he or she eats too much or too quickly, nausea and vomiting may result. Some patients may need a longer period of time to change their eating habits. The diet should be mainly liquid for 2 weeks after surgery, then soft meals for 2 to 4 weeks and then solid foods can be added gradually. Sometimes it may take 3-6 months to get used to it. Slight vomiting and flatulence are common. The amount of food consumed will gradually increase after 6 months. After about a year, you will feel full after eating half a sandwich and half a drink. It is important to understand that the progress varies from person to person. Eat small and slow portions, and separate food and drinks as much as possible when eating. In addition, about 1 in 5 people may have acid reflux after surgery and may need medication. This condition will gradually subside in 6 to 12 months. You should receive long-term dietary counseling from a dietitian within six months after surgery to avoid malnutrition.
