Gastric Bypass Surgery

Gastric bypass surgery uses a combination of restriction and malabsorption. During the procedure, the surgeon creates a smaller stomach pouch. The surgeon then attaches a Y-shaped section of the small intestine directly to the pouch. This allows food to bypass a portion of the small intestine, which absorbs calories and nutrients.

Having the smaller stomach pouch causes patients to feel full sooner and eat less food; bypassing a portion of the small intestine means the patient's body absorbs fewer calories. This is still the most common type of weight-loss surgery performed in the United States. It is still considered the "gold standard" in weight loss surgery.

Advantages may include:

  • You eat less and absorb less
  • Decreases appetite/prolonged sense of fullness after small meals
  • Rapid initial weight loss
  • Laparoscopic procedure is minimally invasive/does not require open procedure in most cases
  • Greatest percent of excess body weight lost in a shorter period of time
  • Best resolution of comorbidities
  • Is reversible

Disadvantages may include:

  • Requires cutting stomach, stapling and intestinal re-routing
  • Requires patient discipline/commitment to avoid nutritional deficiencies and malnutrition by sticking to a simple supplement plan
  • Increased gas
  • Possible intolerance to sweets and simple carbohydrates
