Weight loss metabolic surgery has been developed for more than 70 years in foreign countries, and its technology and theory have been very mature, according to statistics, more than 1 million people worldwide get rid of obesity and diabetes through this surgery every year. In China, weight loss and metabolic surgery has a history of nearly 20 years, and so far, the number of people receiving such surgery is more than 10,000 every year, and is still growing at a rate of 30% per year. Because of the relatively short awareness of the obesity problem in China and the relatively late start of weight loss metabolic surgery, the popularity of this surgery is far less than that of developed countries such as Europe and America. Although the development of domestic weight loss metabolic surgery has been rapid in the past two years, only a few medical teams such as Youdao Doctor Group have been carrying out related surgeries in China for more than ten years, and the authoritative experts of domestic weight loss metabolic surgery are basically concentrated in these medical teams. However, putting aside the technical problems of doctors, the domestic system of weight reduction and metabolic surgery is more suitable for people in the Asia-Pacific region than overseas. There are certain differences between people in the Asia-Pacific region and people in Europe and the United States in terms of body shape, and different criteria for determining obesity lead to different surgical standards, for example, the biliopancreatic bypass commonly used abroad is not very suitable for people in the Asia-Pacific region. In addition, people in the two regions also have big differences in their dietary habits and living habits, so the experience of post-operative management is generally not universal. For domestic obese people, doing weight reduction and metabolic surgery in China will be more advantageous in terms of surgical standards and post-operative management, but due to the problem of short popularization time, it is better to choose those doctors who have been carrying out the relevant surgery for a longer time and have a team of experienced surgeons to carry out the surgery, which will be a bit more secure.
