When it comes to obesity, probably the first impression most people have of fat people is that this person is really fat! In fact, in the world of fat people, it is not just as simple as a bulky body, but also may cause complications, obesity is not terrible, what is terrible is the complications. So is it possible to lose weight with surgical sleeve gastrectomy? Introduction of sleeve gastrectomy surgery side effects? Sleeve Gastrectomy: The full name is laparoscopic gastric reduction surgery, also known as sleeve gastrectomy. The principle of gastric reduction surgery is to use a laparoscope to cut out the large curve of the stomach vertically, so that the stomach forms a small gastric sac 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 procedure is remarkably effective for weight loss. Method: 2-6 cm of the sinus above the pylorus is preserved in the direction of the greater curvature of the stomach, and the larger part of the stomach is removed along the long axis of the stomach, and the entire fundus is removed, leaving a “banana-shaped” stomach with a volume of about 60-80 ml. 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 Europe at present. What are the side effects of sleeve gastrectomy? The results of sleeve gastrectomy are somewhere between gastric bypass and gastric banding, and the safety is somewhere in between, making it a fairly “middle of the road” procedure. If compared to gastric bypass, sleeve gastric surgery does not perform intestinal reconstruction, so there are no long-term sequelae such as anemia and osteoporosis due to vitamin deficiency. Although the procedure is very safe, there are certain things to keep in mind. First of all, the patient’s eating habits may change considerably after the surgery. If the patient eats too much or too fast, it may cause nausea and vomiting. 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.
