Roux-En-Y Gastric Bypass

Risks common to all surgeries for weight loss include an infection in the incision, a leak from the stomach into the abdominal cavity or where the intestine is connected (resulting in an infection called Reference peritonitis Opens New Window), and a blood clot in the legs (Reference deep vein thrombosis Opens New Window, or DVT) or lung (Reference pulmonary embolism Opens New Window). Some people develop Reference gallstones Opens New Window or a nutritional deficiency condition such as Reference anemia Opens New Window or Reference osteoporosis Opens New Window.

Other risks from Roux-en-Y gastric bypass include:

• Stomach pouch problems. You may need a repeat surgery to repair the stomach and/or the opening between the stomach and the intestine.
• Vomiting. If you eat more than your stomach can hold, you may vomit.
• Hernia. These can be related to the incisions that the surgeon makes or caused by the intestines twisting around itself.
• Kidney stones. Drinking enough water can help.
• Gallstones. Sometimes the gallbladder is removed as part of the surgery. But if your gallbladder is not removed, then you may need to take medicine to prevent gallstones.
