It may be the first time you hear about the medical technique of gastrectomy for weight loss, but it is easy to guess what the procedure is like based on the meaning of the words. If you need to go deeper, you may not understand, so let’s take a look at what gastrectomy is. Gastric resection, also known as sleeve gastrectomy, or “gastric reduction surgery” is a procedure that more people know about. This surgery was included in the regular weight loss surgery by the U.S. Food and Drug Administration in April 2008, and now more than 200,000 people around the world have had the surgery. The development of weight loss surgery abroad started earlier than in China, and this surgery is now a more common weight loss method in developed countries and regions abroad, and is preferred by the public. The function of the stomach is mainly to digest food, so the volume of the stomach is reduced, so you can feel full soon after the surgery, reducing the amount of food intake and digestion. As a result, the amount of food intake is reduced and the amount of digestion is also reduced, thus achieving the effect of weight loss. Gastric resection surgery saves a lot of effort compared to other conventional weight loss methods. According to the increasing obesity situation in China, gastrectomy will most likely become one of the mainstream weight loss methods, and the pace of development of weight loss surgery in China is getting faster and faster, and there are already many medical institutions carrying out weight loss surgery techniques one after another. The future development of gastric resection is worth looking forward to.
