Gastric Bypass

The Gastric Bypass helps our patients lose weight in four different ways.

First, your surgeon will create a small (15cc) pouch from the upper part of the stomach. Just by doing this, you will have restriction in the amount of food that you can ingest at any time. The remaining stomach, called the gastric remnant, is left in place. It still has a viable blood supply and will continue creating gastric acids needed for digestion. The remnant will no longer be able to accept food or drink.

Secondly, part of the small bowel is bypassed (approx. 150 cm). This creates malabsorption of calories, nutrients and vitamins/minerals.

Thirdly, bypassing the lower stomach creates a reduction in the “Hunger Hormone” called grehlin, which decreases the appetite in general.

Fourth and final, the bypassing of the small intestine makes it hard to digest sugar and fat. Eating too much of those foods will trigger an episode we call “dumping”, which can include the following: abdominal pain, rapid heart rate, nausea, diarrhea, sweating, vomiting and general malaise. These episodes can last from one hour to all day. While some may consider dumping unpleasant, it is a wonderful reminder to eliminate those bad foods from your diet. We think of dumping as a benefit of the bypass procedure.

The Gastric Bypass can be a really great procedure for the right patient.  An optimal patient for Gastric Bypass must understand and be willing to follow a few rules:

  1. Tobacco products must be avoided
  2. Most steroids (including injections) must be avoided
  3. Non-steroidal anti-infammatory medications must be avoided
  4. Vitamin supplementation is a life-time commitment


  • Fast Weight Loss
  • Quicker Resolution of Weight-Related Illnesses
  • Dumping
  • Faster Improvement or Cure to Diabetes
  • No Adjustments Needed


  • More Invasive Procedure
  • Life-Long vitamin Supplementation Required
  • Potential for inadequate weight loss or weight re-gain
  • Greater potential for vitamin and mineral deficiencies due to malabsorption
  • Increased risk of ulcers and small bowel obstructions
