Since its reform and opening up, China’s development has become the most successful case of the global economy. No country in history has ever developed so rapidly. However, as China has grown and become increasingly international, people’s lifestyles have changed. As of 2016, China has the largest obese population in the world, with nearly 90 million people, including 43.2 million men and 46.4 million women. Modern lifestyles have made people suffer from high calorie intake and sedentary lifestyles, which is making China face a growing obesity crisis, especially among the younger generation. Indeed, China is seeing a fourth significant increase in childhood obesity. It is estimated that 23% of males under the age of 20 are obese or overweight, and 14% of females are obese or overweight. In China, the proportion of obese boys is almost twice the proportion of obese adult males. And, 9.6% of young people are overweight, of which 6.4% are obese. For many obese people who have tried a variety of weight loss methods but still not effective, weight loss surgery is now a method that can be effective in the long term, not only for weight loss, but also for improving a variety of metabolic syndromes caused by obesity, such as diabetes, fatty liver, high blood pressure, hypertension, sleep apnea syndrome, etc. It can be a multi-benefit. In 2015, the prestigious Cleveland Medical Center announced the top 10 medical innovations of 2015, and weight loss surgery for diabetes was ranked third. The main surgical procedures used are laparoscopic sleeve gastrectomy and gastric bypass, which are characterized by less trauma, faster recovery, lower risk and fewer complications. The surgery allows diabetic patients who meet the indications for surgery to achieve remission after surgery. Some domestic statistics show that diabetic patients with significant results after surgery have a surgical efficiency of 95% and a complete remission (radical) rate of more than 83%.
