Since our country overtook the United States to become the world’s largest obese population, public awareness of the dangers of obesity has been increasing, and more and more people have begun to treat obesity through various methods, and the effective means of treating obesity, weight loss metabolic surgery, has been greatly popularized, and the number of surgeries is increasing day by day, but despite this, the situation of obesity has not been effectively alleviated. Recently, the world’s leading medical journal “The Lancet” published a report that, globally, nearly 2.3 billion children and adults are overweight, and this situation may affect several generations. The report points out that those obese countries have a generally imbalanced diet, with less fresh food healthy food and more industrially processed food on the market, and if adjusted, it is difficult to alleviate the obesity problem. More serious is that obesity can be inherited, many studies have shown that the obesity rate of children in families where both parents are obese is much higher than that of children whose parents are of normal weight. The reason for this situation is not only the genetic inheritance of obesity, but also the parents’ eating habits and attitude towards obesity. So if not timely treatment of obesity and correct those bad habits that easily lead to obesity, it is easy to form family obesity. With the current medical technology, although severe obesity can be effectively relieved by weight reduction metabolic surgery, it still depends on post-operative management to achieve good long-term weight reduction results. For this reason, domestic weight loss metabolic centers such as Youdao Doctor Group have established a perfect post-operative management system to help patients improve their life and diet habits through long-term follow-up guidance by health managers and nutritionists to ensure the long-term effect of surgery.
