Some data show that the overweight and obesity rates of Chinese people have grown explosively in the past 20 years. From 1992 to 2015, the overweight rate rose from 13% to 30% and the obesity rate from 3% to 12%. Meanwhile the obesity rate of Chinese children and adolescents is also increasing rapidly. Sleeve Gastrectomy for Weight Loss: Fully known as Laparoscopic Gastric Reduction Surgery, also known as Sleeve Gastrectomy (LaparoscopicSleeveGastrectomy), Gastric Reduction Surgery is based on the principle of using laparoscopy to cut out the greater curvature of the stomach vertically, so that the stomach is formed into a small gastric sac of about 150 cc, which can hold about 4-5 ounces of food. It has the advantage of not requiring the placement of foreign objects in the body, and the surgery is highly effective in weight loss. Method: Preserve 2-6cm of the gastric antrum above the pylorus in the direction of the greater curvature of the stomach, resect the large part of the stomach along the long axis of the stomach, and resect all of the fundus of the stomach, so that the remaining stomach is in the shape of a banana, with a volume of about 60-80ml. Principle: Reduce the volume of the stomach and decrease the secretion of hormones that stimulate hunger. Advantages: Does not change the physiological state of the gastrointestinal tract and does not interfere with the normal digestion and absorption of food. Evaluation: Sleeve gastrectomy has a favorable therapeutic effect on type 2 diabetes and is now a widely used surgery for weight loss and diabetes in Europe. RESULTS: Studies have shown that patients undergoing bariatric and diabetic surgery have complete glycemic relief in type 2 diabetes compared to patients treated only with traditional medications. At 2 years after undergoing gastric bypass, patients had a diabetes remission rate of 75%. Diabetes remission was defined as having a glycosylated hemoglobin <6.5% and not taking medication. In addition, weight loss and diabetes surgery can significantly address or improve type 2 diabetes and other obesity comorbidities. Studies have shown that weight loss and diabetes surgery resolves or improves diabetes in 86% of patients, improves hyperlipidemia in 70% or more, resolves or improves hypertension in 78.5% of patients, and resolves sleep apnea in 85.7% of patients. In addition to controlling blood glucose, undergoing weight loss and diabetes surgery reduces the use of medications for diabetes, hypertension, and hyperlipidemia, among other comorbidities. While controlling blood sugar, undergoing weight loss and diabetic surgery also reduces the use of medications for diabetes, hypertension, hyperlipidemia, and other complications, with varying degrees of improvement in overall health, emotional well-being, physical and social functioning, pain relief, and restoration of personal energy. The emergence of weight loss surgery has given hope to obese patients. Moreover, for diabetic patients, weight loss is not only about overcoming the harmful effects of fat on blood glucose, but more importantly, it is also about reducing insulin resistance, protecting the function of existing pancreatic islets, increasing the utilization of blood glucose by muscles, lowering blood pressure, regulating lipids and other all-around advantages, so it is very important that diabetic patients have a very high level of weight management.
