Compared to surgical weight loss surgery, people are more willing to try conventional weight loss methods first because dieting and exercise are less costly and more importantly, at best, they will fail to lose weight and do not seem to cause much harm to the body. Surgery is a different story. In most people’s perception, the mention of surgery is a matter of risk and sequelae, and they are full of worries about it. In recent years, surgical weight loss has gradually entered the public eye, and gastric bypass surgery has begun to receive widespread attention. At the same time, many people want to know if there are any after-effects of this surgery. After a long period of experience and keeping up with the times, gastric bypass surgery is now a very mature and safe procedure as a part of bariatric surgery. Gastric bypass surgery changes the structure of the intestine and shuts down most of the gastric functions, dividing the patient’s stomach into two parts, so that only 1/6-1/10 of the original stomach is used to hold food. This will slow down the emptying of the stomach, shorten the small intestine and reduce absorption, thus achieving the goal of weight loss. From the point of view of the procedure, the main operation of the surgery is concentrated in the gastrointestinal system of the human body, and as for the risks and sequelae of the surgery, it is clear that there are certain risks in any surgery. However, it is important to note that the same procedure can have different results in terms of risk control for that procedure when operated by different surgeons. Dr. Wu Liangping, who has 10 years of experience in bariatric surgery, is not only comfortable with the operation, but will also develop a surgical plan based on the patient’s specific situation, so that the patient can be treated more effectively and with more confidence, effectively reducing the risk of surgery and avoiding complications later. Therefore, before having gastric bypass surgery, you need to screen the many surgical weight loss medical centers in China and choose an experienced and skilled surgeon to better protect yourself.
