Many factors can cause gastric sleeve surgery to be less successful than expected, and it’s important to meet with a specialist bariatric surgeon to understand the best options for you. Some people may start to quickly gain weight again due to the stomach pouch or sleeve stretching so that the initial restriction provided is no longer effective. Alternatively, during the original operation the surgeon may not have reduced the size of the stomach sufficiently to prevent overeating.
If you’ve regained weight after your gastric sleeve surgery, you may be able to convert to a gastric bypass to reignite your weight loss. Alternatively, you may be too restricted and be losing too much weight, and a conversion to a bypass may be the solution.
While the gastric sleeve procedure restricts the amount of food that you can eat, the gastric bypass is a combination of restrictive and malabsorptive procedures. By reducing the size of the stomach and also limiting the amount of calories and nutrients that the body absorbs, it has a two-fold weight reduction effect.
