Roux-en-Y Gastric Bypass Surgery

If you are severely obese and unsuccessful at losing excess weight by dieting, exercising and changing your behavior on your own, you may be a candidate for Roux-en-Y gastric bypass surgery.

This minimally-invasive procedure makes your stomach smaller and changes the way your body digests food. The surgery creates a bypass so food no longer goes into some parts of your stomach and small intestine. The procedure uses staples to create a small pouch at the top of your stomach. Part of your small intestine is shaped into a “Y” and is connected to the small stomach pouch. When you eat, food travels from the pouch to the lower small intestine. This reduces the amount of calories your body absorbs.

To qualify for gastric bypass surgery, you must have a body mass index (BMI) of 40 or higher. If you suffer from other complications of obesity, you may be a candidate with a BMI of 35 or higher. Patients who qualify for surgery generally are 100 or more pounds above their ideal weight.

If you also have health conditions like Type 2 diabetes or hypertension, you may benefit from Roux-en-Y gastric bypass surgery.

Gastric bypass is an aggressive surgery. The anatomical and physiological changes to your body make it inevitable that you will lose weight. Many patients experience a lack of appetite up to a year after surgery.

You can lose 10 to 20 pounds a month in the first year after surgery. Weight loss after surgery can improve other existing medical conditions including high cholesterol, sleep apnea and osteoarthritis.

You must commit to making many changes in your lifestyle before undergoing gastric bypass surgery. The procedure will not be successful if you do not follow your recommended diet and exercise plan.

At Indiana University Health, our affiliation with the IU School of Medicine Division of General Surgery gives us access to the latest surgical advances for obesity.
