Roux-en-Y Gastric Bypass—Laparoscopic Surgery
Pronounced: Roo-n-y gas-trick bye-passEn Español (Spanish Version)
Roux-en-Y gastric bypass is a surgery for obesity. It changes the size of the stomach and small intestine to cause weight loss by:
- Restricting food intake—creates a small pouch to serve as the stomach, so you cannot eat as much
- Making the body unable to absorb as many calories from the food—bypassing the first part of the small intestine, where many of the calories from food are usually absorbed

The surgery treats severe obesity. A calculation called body mass index ( BMI) is used to determine how overweight or obese you are. A normal BMI is 18.5-25.
Roux-en-Y gastric bypass is a weight loss option for people with:
- BMI greater than 40
- BMI 35-39.9 and a life-threatening condition or severe physical limitations that affect employment, movement, and family life
The success of gastric bypass surgery depends on your commitment to lifelong health habits. If lifestyle changes are made and maintained, the benefits of bariatric surgery include:
- Long-term weight reduction
- Improvement in many obesity-related conditions
- Improved movement and stamina
- Enhanced mood, self-esteem, and quality of life
