There are many diseases associated with the human body that require the removal of problematic tissues or even organs in the body to treat the condition, and many people should have heard of appendicitis, which can be solved by simply removing the appendix. Many people associate appendectomy with gastric reduction surgery, believing that it can be performed by removing most of the stomach to achieve weight loss. The reason is not necrosis or infection of the stomach, but mainly to reduce the volume of the stomach, to limit the body’s food intake after surgery, to reduce nutrient absorption, and to accomplish the goal of weight loss. The removed stomach will be taken out of the body, leaving only one third of the stomach to store and digest food. After a long period of adaptation and recovery after the surgery, it will be possible to avoid excessive caloric intake in daily eating life and achieve effective weight loss while preventing further obesity. Gastric reduction surgery is an irreversible procedure, and it is important to consider this carefully as it does not mean that the stomach can be restored to its original state just by putting back the removed part. If you can’t make up your mind because you’re worried about the results of the surgery, don’t worry too much. Although the surgery is irreversible, it is possible to change the procedure from a gastric reduction to a sleeve gastrojejunostomy. As you can see, sleeve gastrojejunostomy is an addition of jejunostomy to gastric reduction surgery, which serves to reduce the body’s nutrient absorption and further enhance the effect of weight loss. Therefore, gastric reduction surgery has also become a surgical weight loss procedure with a high number of cases in recent years in China. Although gastric reduction surgery does not provide the same immediate results as appendectomy, it is safer than appendectomy in terms of surgical safety. Gastric reduction surgery as a form of weight loss many people are reluctant to accept, but in fact it is a routine minimally invasive surgical procedure, and in hospitals with relatively mature technology there is basically no need to worry about the safety of the surgery.
