GastricBypassA Roux-en-Y gastric bypass is a restrictive and malabsorptive surgical procedure which keeps you from eating a lot of food at one time and absorbing everything you eat. Through this surgery, a 1- 1 ½ ounce pouch, about the size of an egg, is made from the stomach and connected to a re-routed portion of the small intestine, changing the digestive pathway of the food you eat.

Surgery and Recovery

  • Surgery one-and-a-half to two hours
  • Two- to three-day hospital stay
  • Two- to four-week recovery period


  • Fastest and greater weight loss on average, with 60 to 80 percent of the expected weight lost being lost 18 to 24 months after surgery
  • More successful at helping patients improve weight-related conditions like Type 2 diabetes


  • Leakage through staples or sutures that hold stomach and intestine together
  • Injury to spleen during surgery
  • Ulcers could develop in the stomach or small intestine
  • Blockage of stomach opening
  • Internal hernias
  • Vitamin and iron deficiency

Other Considerations

  • Not reversible
  • Fastest weight loss
  • Nausea and “dumping” syndrome with certain foods (large amounts of sugar may cause diarrhea and sweating – some with a sweet tooth consider this a benefit, to help curb sugar cravings)
  • Vitamins mandatory
  • Not allowed to take aspirin or NSAIDs afterward
  • Able to eat regular food after two weeks of surgery
