Roux-en-Y Gastric Bypass—Laparoscopic Surgery
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

If you are planning to have Roux-en-Y gastric bypass, your doctor will review a list of possible complications, which may include:
- Blood clots
- Pulmonary embolism
- Hernia formation
- Bowel obstruction
- Breakdown of the staples, allowing leakage of stomach juices into the abdomen
- Diarrhea, abdominal cramping, and vomiting
- Dumping syndrome—This occurs after eating sweets, when food moves too quickly through the small intestine causing sweating, fatigue, lightheadedness, cramping, and diarrhea .
- The need for additional surgery
- Complications of general anesthesia
Long-term complications include vomiting and gallstones.
Before your procedure, talk to your doctor about ways to manage factors that may increase your risk of complications, such as:
- Chronic diseases, such as diabetes
