Gastric Bypass

The Roux-en-Y Gastric Bypass creates a smaller stomach. A Y-shaped section of the small intestine is attached directly to this pouch allowing food to bypass a large portion of the small intestine eliminating some food absorption. It’s reported that the smaller stomach pouch makes patients feel fuller sooner and eat less food.*

What to Expect After the Gastric Bypass Procedure:

Recovery time is moderate and most patients are able to leave the hospital within a few days and return to work and semi-normal activity in less than a month.* Gastric bypass patients typically lose over 80 percent of their excess weight, and most patients report that Type 2 Diabetes, high blood pressure and cholesterol have been improved or resolved.*

Considerations and Risks of Gastric Bypass:

Patients must supplement their diet with a daily multivitamin and calcium and some patients will have to take vitamin B12 and/or iron. The stomach, duodenum, and parts of the small intestine cannot be seen easily using X-ray or endoscopy if there are complications after surgery such as ulcers, bleeding, or malignancy. As with any surgical procedure there are inherent risks.

Other risks include:

  • Dehiscence (separation of tissue
    that was stitched or stapled together)
  • Leaks from staple lines
  • Ulcers
  • Dumping syndrome, an unpleasant side effect that may include vomiting, nausea, weakness, sweating, faintness, and diarrhea
  • Increased gas
