When it comes to weight loss surgery, when looking at the name, the most obvious result is undoubtedly weight loss. But there are hundreds of weight loss methods in the world, so why should you choose weight loss surgery to lose weight? What is the biggest difference between bariatric surgery and other weight loss methods? The two most important features of bariatric surgery are the long-term effectiveness of the weight loss effect and the fact that bariatric surgery is not only for weight loss, but also for the treatment of various metabolic diseases at the same time. The American medical journal Annals of Surgery published a paper on the effectiveness of bariatric surgery as early as 1995. According to a multi-year follow-up after surgery, after 14 years of bariatric surgery, patients were able to lose 50-60% of their excess weight, and the effect of bariatric surgery was effective in the long term. There are a lot of literature reports: the medium and long-term effective satisfaction rate of weight loss surgery is as high as 85%~97%, and it has become the only long-term effective method to treat obesity, which fundamentally solves the problem of food intake and nutrient absorption, and after the surgery, patients who have lost weight are able to maintain a healthy weight range steadily for a long time under the guidance of the health manager. Of course, weight loss surgery is more than just weight loss, it can effectively improve the metabolic index of a variety of obesity-related morbidities. According to years of clinical data, 80% of type 2 diabetic patients who underwent bariatric surgery achieved complete remission, normalized blood sugar, normalized glycosylated hemoglobin, freed patients from lifelong medication, and improved fatty liver in 90% of cases; the mortality rate of obese patients was reduced by 89% within 5 years. Bariatric surgery can also effectively address and improve cardiovascular disease. over 70% of patients have improved hyperlipidemia and over 78.5% of patients have improved hypertension symptoms. For polycystic ovary syndrome combined with obesity, bariatric surgery is one of the effective treatment options. In addition, sleep apnea, a terrible condition that tends to cause patients to die quietly in their sleep, can be treated even more effectively with weight loss surgery. In fact, patients who undergo bariatric surgery experience varying degrees of improvement in overall health, emotional psychological, physical and social functioning, pain relief, and personal energy recovery, with 95% significant improvement in quality of life and some increase in average life expectancy compared to medication. Therefore, bariatric metabolic surgery is not a bariatric surgery in the general sense, but a life-saving surgery.
