Roux en Y Gastric Bypass: As “gastric bypass surgery” implies, this surgical procedure routes food past most of the stomach and the first part of the small intestine. In addition to restricting food intake, a Roux-en-Y Gastric Bypass reduces nutrient absorption. Gastric bypass surgery involves three main steps: 1. Creating a new, smaller stomach (gastric pouch) from the existing stomach. 2. Bypassing 3 to 4 ft. of the small intestine (normally 20 ft. long). 3. Connecting the bypassed digestive section to the lower section of the small intestine, where necessary digestive juices mix with food. The small pouch of stomach can hold about 1/3 cup of food. After this, it begins to stretch, giving you the feeling of fullness. Although in most people it will give a feeling of fullness, in some people the stretching may give a feeling of discomfort. The small stomach pouch will need time to digest the food and push it through the GJ (gastrojejunostomy) opening into the small bowel. If you do not give enough time to do this, you may start vomiting. Post-Op Dietary Plan for Roux en Y Gastric Bypass Surgery Patients As with all surgical weight-loss programs, it is imperative that Roux en Y patients adhere to dietary recommendations following surgery. For the first 18 months after gastric bypass surgery, patients must restrict themselves to consuming less than 800 calories per day; after 36 months, patients may consume no more than 1200 calories each day. In addition, patients must avoid eating sugars and fats to prevent “Dumping Syndrome.” Surgical Procedure and Hospital Stay -Over 98% of Gastric Bypass Surgery RYGBâ€™s are performed laparoscopically, with an average of 6 small incisions. They all require full general anesthesia and about 2 hours of surgical time. Most patients stay one or possibly two nights in the hospital. How much weight loss is achieved? The vast majority of patients lose 50 to 80% of their excess weight in the first 12 months of Weight Loss after gastric bypass surgery. With the roux-en-y gastric bypass, most patients keep 50% to 70% of their excess weight off after 10 years. However, some patients can regain some or much of their original weight. After the first 2 years, there is a very slow weight loss depending on the eating habits and exercise commitment of the patient. If you successfully use the preoperative period to adapt your lifestyle and train yourself to eat differently, this small pouch helps to remind us to eat less food. Thus, the intake of food is dramatically limited and enables us to lose weight, and keep the weight off lifelong. Although there is some malabsorption of certain types of minerals and vitamins as described above, the food that is eaten will be well digested and nearly completely absorbed. This enables us to maintain good nutritional status and remain healthy with proper eating.
