The Doctors: Is gastric bypass right for you?

The Doctors

Gastric bypass is the most common weight-loss surgery, and research shows it’s the most effective. Here’s what you should know about the procedure.

Your stomach becomes the size of a walnut. That’s the first step in Roux-en-Y surgery, the most common method of gastric bypass. Surgeons divide your stomach to create a small upper portion, sealed off from a larger bottom section. That pouch is where the food goes; it holds only 1 ounce. (The stomach’s capacity is about 48 ounces.)

Next, surgeons will connect the pouch directly to the middle of the small intestine. The result: food intake per meal is limited and fewer calories are absorbed.

Surgery may help you Lose 60 percent of excess weight

New research on mice suggests the surgery also may change the makeup of microbes in the intestine, which contributes to weight loss.

Scientists don’t know whether the same effect applies to humans, but what they do know is, on average, people lose about 60 percent of excess weight in the first year.

BMI numbers matter

If your body mass index (BMI) is 40 or higher, gastric bypass or other weight-loss surgeries could be an option; it’s also considered for those with a BMI of 35 or more and a serious weight-related health problem.

Obesity isn’t the only factor for weight-loss surgery; doctors also evaluate diet history, all medical conditions and psychological health to make sure the surgery is safe and the patient can maintain the benefits.

The risks

It comes with risks. Some are short-term, such as excessive bleeding, infection, leaks in your gastrointestinal system or increased risk of blood clots; later, potential side effects can include hernias, ulcers or poor absorption of nutrients.

Post-surgery care

Post-surgery maintenance lasts a lifetime.

You’ll follow a liquid diet for the first few months. To keep weight off and avoid complications, you have to stick to a strict diet and exercise plan — keep meals small, eat slowly, chew thoroughly and take vitamins and minerals as directed by your physician.
