Bariatric surgery is becoming more and more important in weight loss or in the treatment of diabetes, and the country is also following the trend of the times, and the related weight loss technology is gradually maturing. However, bariatric surgery is still limited by people’s perceptions and other reasons, and there are still more people in China who feel that it is unnecessary to do surgery or worry about unsafe. In terms of the operational difficulty of weight loss surgery, stomach reduction surgery is a relatively simple procedure, but of course there are also more difficult procedures, such as gastric bypass surgery, which requires a high level of skill on the part of the surgeon in charge. For example, gastric bypass surgery requires a high level of skill from the surgeon in charge. An experienced and skilled surgeon is able to handle unexpected situations during surgery and has the strength to grasp the details of various operations. In terms of the form of surgery, no matter what type of surgery, weight loss surgery is performed laparoscopically, which is a minimally invasive surgery, and has the advantage of low risk and high efficiency compared to traditional open surgery as perceived by the public. Weight loss surgery has been going on for more than 60 years, so the surgery itself has passed the test of time in terms of its usefulness and effectiveness. So far we have mentioned the safety issue, since there is no problem with the surgery itself, the problem lies with the person operating the surgery. As mentioned earlier, experienced doctors have completed a higher number of surgical cases and have encountered or dealt with more unexpected situations, so choosing a good lead surgeon is also equivalent to adding more guarantees to the surgery.
