But each person’s obesity reasons are different, and all these methods are almost ineffective for fat people who have reached heavy obesity (BMI>35), so those who have really reached obesity are still troubled by obesity after experiencing these so-called weight loss measures and spending a lot of wasted money, and even have diseases caused by indiscriminate weight loss children. The degree and cause of obesity are different, the treatment and measures taken should be very different, in Jiangsu Provincial People’s Hospital weight loss and metabolic surgery according to different fat people to take different weight loss methods to achieve the best weight loss effect, for those patients who are mildly obese can take the diet regulation and calorie control program, mainly have the nutrition department experts to provide the program to follow up, for those who are caused by endocrine diseases, such as hypothyroidism, tumor, etc. mainly through the endocrine disease. For those who are purely obese, especially those who are not effective after repeated conservative treatment, we can adopt surgery to lose weight and treat the complications of obesity, such as diabetes, polycystic ovary infertility, hypertension, hyperlipidemia and so on. Weight loss should be individualized, and two patients with the same degree of obesity may undergo different surgical procedures. First of all, it is important to understand that gastrointestinal surgery is the most reliable way to lose weight and the only way to maintain weight for a long time, and laparoscopic bariatric surgery is less invasive, with faster recovery and smaller scars. The main laparoscopic bariatric surgery modalities currently available are laparoscopic sleeve gastrectomy, and laparoscopic gastric bypass, as well as a number of other procedures. The decision on the type of bariatric surgery to be performed depends on the patient’s age, obesity level, weight requirements, education level, family support, financial situation, etc. For type 2 diabetic patients, it is necessary to decide the surgical procedure according to the degree of obesity and diabetic condition. In short, for obese patients, comprehensive consideration should be given to the specific situation of the patient to decide which weight loss method is most appropriate.
