Patients with obesity have common characteristics such as slow movement, sleepiness, and a tendency to overeat. Many of them also have other diseases, such as diabetes, high blood pressure and even heart disease. What about surgery to treat obesity? Are there any after-effects of surgical gastric bypass for weight loss? Bariatric gastric bypass surgery: Gastric bypass surgery refers to a series of similar surgical procedures used to treat obesity, with the following common features: the surgery first divides the stomach into two parts, the smaller upper part, and the larger lower part, then truncates the small intestine, rearranges the position of the small intestine, changes the pathway of food through the digestive tract, slows down gastric emptying, shortens the small intestine and reduces absorption. By 2005 surgeons had developed several different alignment options, forming several branches of gastric bypass surgery. According to 2008 data from the National Center for Health, gastric bypass surgery has replaced gastric reduction surgery as the most popular weight loss procedure in the United States since 2000, with about 100,000 cases performed each year. Weight loss surgery can take off 60-80% of your excess weight, and the results can be even better if your post-operative diet and exercise habits are well coordinated, with the support and assistance of a professional health manager. Bariatric gastric bypass results: Studies have shown that patients who underwent weight loss and diabetes surgery were able to achieve complete blood glucose remission in patients with type 2 diabetes compared to those who only underwent traditional medication. Two years after receiving gastric bypass, patients had a 75% remission rate of diabetes. Diabetes remission was defined as glycosylated hemoglobin <6.5% and no medications. In addition, weight loss with diabetes surgery significantly addresses or improves type 2 diabetes and other obesity comorbidities. Studies have shown that bariatric and diabetic surgery resolves or improves diabetes in 86% of patients, improves hyperlipidemia in 70% or more of patients, resolves or improves hypertension in 78.5% of patients, and resolves sleep apnea in 85.7% of patients. Are there sequelae of bariatric gastric bypass surgery? Gastric bypass surgery does not remove any organs of the body, does not damage the integrity of the gastrointestinal tract, and does not alter the inherent physiological state of the gastrointestinal tract, does not affect feeding and nutrient absorption, and causes minimal harm to the body. Gastric bypass surgery has been performed in the United States, Europe and other countries for more than 30 years, and no side effects have been observed. A comprehensive analysis of 32,094 patients showed that 84% of type 2 diabetes was completely reversed after surgery, and no side effects were observed at follow-up visits after treatment.
