Gastric Bypass is both a restrictive (decreases food intake by making the stomach smaller) and malabsorptive (decreases the amount of nutrition the body is able to absorb from the intestinal tract) surgery technique. A small stomach pouch is created and the remainder of the stomach is completely stapled shut but is not removed. The surgeon then attaches a section of the small intestine to the pouch. The small pouch causes you to feel full sooner and the bypass portion of the small intestine means you absorb fewer calories and nutrients, thereby losing weight. Gastric bypass surgery can cause an average loss of 61% of excess weight.


  • Limits the amount of food that can be eaten and reduces the desire to eat, leading to rapid weight loss
  • Excess weight loss is generally greater than with the Gastric Band or Sleeve Gastrectomy
  • Resolves diabetes, high cholesterol and sleep apnea in a large percentage of patients
  • Many patients exhibit >90% reduction of serious health problems

In addition to the general risks that accompany all surgeries, this procedure may:

  • Lead to an increased risk for nutritional deficiencies related to the malabsorptive component of surgery
  • Potentially cause leaks along staple line
  • Dumping Syndrome (intense feeling of being ill because of simple sugars or fat)
  • Certain parts of the digestive system can no longer be easily visualized with common medical tests
