Gastric Bypass

The Roux-en-Y gastric bypass is considered the gold standard of weight loss surgery available today. The procedure creates a small stomach pouch—about the size of an egg—to bypass some of the small intestine, restricting food intake and limiting absorption of calories and nutrients. Additionally, it changes hormones secreted by the gastrointestinal track that can decrease hunger and are thought to have a specific effect on type 2 diabetes. You will typically lose 60-70 percent of your excess weight during the first year after the surgery.

If I undergo a gastric bypass, what happens to the other side of my stomach?

That part of the stomach, called the “gastric remnant,” will no longer see the flow of food but will still function as part of the digestive process. The juices secreted by the gastric remnant will act on the food, but just further downstream.

Is the gastric bypass reversible?

Yes. It is not a common procedure, but one that Dr. Lautz has performed several times for a variety of unusual causes.

Do the staples stay in? Will I set off metal detectors? Can I have an MRI?

The staples used in a gastric bypass are very small and made of titanium, so they do not generally cause metal detectors or MRIs to react.
