Gastric reduction surgery is performed by removing the stomach and reducing the volume of the stomach to achieve weight loss. This method of weight loss is less invasive to the body and can be discharged from the hospital 5-7 days after surgery. So are there any adverse reactions to gastric reduction surgery? Learn more below! Gastric reduction surgery: Gastric reduction surgery is quite a hot topic in the bariatric surgery medical community and its popularity has increased significantly. Because the surgery will cut off 80% of the volume of the stomach, in addition to reducing the amount of food, will also reduce the secretion of the hormone Ghrelin, which stimulates appetite, so the appetite will also be reduced. Within two years after the surgery, approximately 10-15 BMI or 70% of the excess weight can be lost. For those who have a high BMI (over 40) and have difficulty reducing their appetite, gastric reduction surgery can achieve the desired weight loss. The results of gastric reduction surgery are somewhere between gastric bypass and gastric banding, and the safety of the procedure is somewhere in between, making it a fairly “middle of the road” procedure. If compared to gastric bypass, gastric reduction surgery does not involve intestinal reconstruction, so there are no long-term sequelae such as anemia and osteoporosis due to vitamin deficiency. Precautions: Although this procedure is very safe, there are certain things to keep in mind. First of all, the patient’s eating habits may change significantly after surgery. 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, with 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. Food intake 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 experience acid reflux after surgery and may require medication. This condition usually subsides gradually in 6 to 12 months. A dietitian should provide long-term counseling for six months after surgery to avoid malnutrition. If obesity is allowed to continue to develop, it may lead to complications such as diabetes, hypertension, sleep apnea syndrome, etc.
