Roux-en-Y Gastric Bypass

Roux-en-Y gastric bypass surgery is one of the most common and successful weight-loss procedures in the United States. Our surgeons create a small stomach pouch that is attached to the small intestine, bypassing the lower stomach and reducing calorie and nutrient absorption.

The small stomach pouch initially will only hold one to two ounces of food at a time. Once the pouch is full, it takes about 10 minutes or longer for food to pass through to the small intestine. It will take, on average, 30 to 45 minutes to eat a meal consisting of two ounces of meat and one-fourth cup each of a starch, vegetable and fruit.

The time it takes to chew foods thoroughly and the limited space in the stomach pouch reduces the amount of food you can consume at a time. This will cut down on the amount of calories you consume at a given meal, which in turn will help with weight loss.

After surgery, the stomach and the first portion of your intestines (called the duodenum) are bypassed. This prevents you from normally absorbing certain elements from your food like iron, calcium and vitamin B12. Because of this malabsorption, lifetime supplementation with these nutrients is needed. Also, due to the smaller than normal amounts of food that you can consume, a multivitamin rich in thiamine (vitamin B1) is required for life.

Benefits of the Roux-en-Y Gastric Bypass

Most patients lose 70 percent of their excess weight. Gastric bypass surgery has a low complication rate and is performed laparoscopically, which minimizes pain and recovery time. Most patients usually stay one night in the hospital after surgery.

By bypassing the stomach, certain hormones that help regulate your blood sugar increase, and so it’s an extremely beneficial procedure for diabetics. This is the reason gastric bypass patients lose weight faster than patients who only have restrictive surgery.

Who Is a Candidate for This Procedure?

Patients who are more than 100 pounds above their ideal body weight or have a body mass index (BMI) above 40 and have tried to lose weight without success are good candidates for the Roux-en-Y Gastric Bypass procedure. Patients also may qualify for this procedure if their BMI is 30 or higher and they have serious weight-related health problems.
