Fewer calories absorbed, means weight loss. There is one potential problem with mini gastric bypass surgery. Because the pouch is small and is joined close to the flow of digestive juices, it is possible for these juices to reflux up into the stomach pouch causing inflammation and painful ulceration.
The primary difference between mini gastric bypass surgery and a full gastric bypass is that the mini version of the surgery is performed in a modified manner that involves less intestinal rerouting and a shorter overall surgery time. After surgery, you should avoid nonsteroidal anti-inflammatory drugs (NSAIDs), such as aspirin, ibuprofen (Motrin, Advil) and naproxen (Aleve).
