Gastric bypass or Roux-en-Y gastric bypass operations are reversible, but the reversal procedure is risky.
Gastric bypass or Roux-en-Y gastric bypass operations are reversible, but the reversal procedure is risky. The attempt to reverse the bypass to normal anatomy can cause rare but serious complications. The parts of the stomach and small intestine can be put together again but their function will never be quite the same. Most likely, important nerves that regulate the stomach’s emptying are cut during the operations. In this procedure:
- A surgeon creates a small pouch at the top of the stomach. This pouch becomes the new stomach that is small in volume.
- Surgeons then connect the new pouch to the middle part of the small intestine, bypassing the upper part of the small intestine.
- After the surgery, the stomach pouch holds a lot less food than a normal-sized stomach. A person will eat less, feel full sooner, and be less hungry. Also, fewer calories and nutrients are absorbed because the small intestine is shorter.
- People who get gastric bypass tend to lose more weight, but there can be more problems too.
- This procedure not only restricts food intake but also limits the release of hormones in the gut that regulate hunger.
