After gastrectomy, the suture is prone to infection, which will bring some damage to the gastrointestinal tract. After gastrectomy, there will be complications such as gastric acid reflux and heartburn, which will cause anxiety and stomach pain. Therefore, the way of cutting stomach to lose weight is only suitable for simple obese patients who can't lose weight through normal methods and have no endocrine diseases. Gastrotomy (gastric volume reduction) is an effective method for surgical treatment of severe obesity, and sometimes small intestine diversion surgery is also performed at the same time, which not only can lose weight quickly, but also has a strong relieving effect on metabolic indexes such as blood sugar, blood lipid and blood pressure. It has even become one of the standard methods to treat diabetes.

Generally, people who are very fat have very big stomachs, so it is difficult to go on a diet to lose weight, because if they are not satisfied with the food, they will be hungry and unbearable, so they should eat a lot. Stomach reduction surgery usually removes 2/5 or 3/5 of the stomach, which makes the stomach shrink obviously. In this way, it is easy to fill your stomach after eating, and if you eat less, you will be full, avoiding eating too much and achieving the goal of losing weight.
