Although “weight loss” has always been a hot topic in people’s lives, in the eyes of most people, fat or not, it is just a matter of aesthetics or not. In fact, obesity is a disease. Obesity can lead to a variety of complications such as: hypertension, hyperlipidemia, diabetes, high uric acid, sleep apnea syndrome, coronary heart disease, etc., these are the infamous “complicity”. Obesity also has a serious negative impact on the individual’s psychology and social interaction. One is gastric bypass surgery, which short-circuits the small gastric sac to the small intestine to restrict diet and protect islet function; the other is sleeve gastrectomy, which is known as gastric reduction surgery to make the stomach into a “banana” shape to achieve the effect of diet restriction. What are the advantages of weight loss surgery compared to traditional methods? After more than 60 years of clinical testing, hundreds of thousands of people have benefited from weight loss surgery and returned to a normal life. What makes weight loss surgery so popular? Compared to the exercise diet of running for half an hour and losing an apple, the results of weight loss surgery are much more pronounced. After weight loss surgery, obese patients have a significant weight loss. A meta-analysis of large samples from Western countries reported a 65%-70% reduction in excess body mass 1 year after gastric bypass surgery. Weight control from the stomach does not require challenging perseverance, and weight loss is achieved naturally. Long-term stability after surgery Dieting is effective for weight loss, but it is harmful to the body, and the strong rebound after resuming the diet forces people into a cycle of repeated weight loss. Weight loss surgery alters the stomach capacity and digestive distance to keep the patient’s food intake under control. For example, sleeve gastrectomy does not change the physiological condition of the gastrointestinal tract and does not interfere with the normal process of digestion and absorption of food. After surgery, you can no longer endure hunger and no longer worry about rebounding from injury.
