When it comes to weight loss surgery, many people just associate it with liposuction surgery, or even consider it to be the same surgery altogether, which can easily lead to a misunderstanding about weight loss. First of all, I would like to clarify a concept with you that weight loss surgery is not the same as liposuction surgery. Liposuction surgery is one of the plastic and cosmetic surgery body sculpting procedures, the principle is to suck out the excess fat from a certain part of the body through the method of negative pressure attraction, in order to achieve the purpose of local slimming in the short term. Weight loss surgery is a medical procedure that uses medical-surgical means to reduce the weight of obese patients and change their metabolic functions by controlling intake and reducing absorption, so as to cure or alleviate their associated symptoms, such as overweight, high blood pressure, high blood lipids, diabetes and other associated diseases. There are two mainstream medical weight loss methods today, one is sleeve gastrectomy, or what we often call gastric reduction, which removes two-thirds of the stomach without changing the physiological state of the gastrointestinal tract, does not interfere with the normal digestion and absorption of food, does not affect the absorption of vitamins and minerals, has fewer long-term side effects, and has a faster recovery. The other is gastric bypass surgery, which first divides the stomach into two parts, the smaller upper part and the larger lower part, and then truncates the small intestine and rearranges its position, changing the way food passes through the digestive tract, slowing down gastric emptying, shortening the small intestine, and reducing absorption. Compared with traditional treatment options, weight loss surgery is minimally invasive laparoscopic surgery, which is less traumatic, faster recovery, and less risky, with a general operating time of 60-90 minutes, and the ability to get out of bed the day after surgery, and be discharged to work and live normally 3-5 days after surgery. With an effective medium to long-term satisfaction rate of 85%-97%, weight loss surgery is the only long-term effective treatment for obesity. It addresses the root cause of food intake and nutrient absorption and not only reduces weight, but also treats a variety of metabolic diseases associated with obesity.
