Is it worthwhile to go for surgery in order to lose weight? For obesity, especially for patients with severe obesity combined with metabolic diseases, diet, exercise, acupuncture and other methods have little effect and are easy to rebound. With the rapid development of minimally invasive surgical technology, laparoscopic weight loss surgery has become very mature, it is completed through 1-5 small incisions of 0.5-1 cm, significantly reducing the trauma of surgery while significantly improving the cosmetic effect. The number of people who undergo weight loss surgery in the United States exceeds 150,000 to 200,000 each year. The American Society for Metabolic and Bariatric Surgery officially states that bariatric surgery is the most consistently effective treatment for severe obesity and its associated metabolic diseases. Some obese patients have an average disease duration of about 10 years. Due to the lack of health education and the lagging treatment concept, most of them are concerned about the maturity and safety of surgery, and are often afraid of or even resistant to surgical weight loss, so they often try a variety of weight loss methods, but the results are not satisfactory, and finally make up their mind to accept surgery to lose weight. In fact, any surgery is risky, but rigorous and perfect pre-operative examination and standardized operation of doctors can minimize the risk of surgery. Therefore, for obesity patients, weight loss surgery is the only long-term effective weight loss method.
