Our treatments

Your care team will assess your physical and mental condition, your weight-loss goals, medications you take and other factors before recommending a treatment plan.

Gastric sleeve

This procedure, also called a sleeve gastrectomy, is the most common bariatric surgery. About three-fourths of your stomach is removed, reducing capacity for food. Gastric sleeve is less disruptive to your digestive system than gastric bypass.

Gastric bypass

In gastric bypass, your surgeon separates your stomach and creates a small stomach pouch that is hooked to the middle of your small intestine. The rest of your stomach is attached lower to your small intestine. This reroutes food past your stomach and upper intestine, reducing how much food you can take in and changing your metabolism. 

ORBERA gastric balloon

We use a nonsurgical system called ORBERA in which doctors guide a balloon into your stomach. The balloon is filled with saline, leaving less room for food. The balloon is removed after six months. That’s followed by six months of intensive guidance in new eating and exercise habits.

Revisional bariatric surgery

You may be referred to OHSU if a previous bariatric surgery led to complications or too-little weight loss. This happens for only a small percentage of bariatric patients. We are a leading center for revisional surgery to adjust or reverse the original procedure, or to switch to a different treatment.

Lap gastric banding

We rarely do gastric banding surgery, in which a silicon band is put around the upper part of your stomach to restrict food intake. This technique has proved the least effective surgery for weight loss. It also has the highest rate of needing a second operation. Nearly a quarter of bands need to be removed in five or 10 years because of complications or poor results.

Once popular, lap banding now makes up less than 4 percent of U.S. bariatric surgeries. Still, we may consider gastric banding for certain patients. It involves placing a saline-filled band to create a small pouch at the top of the stomach. The band is connected, with a tube, to a port under the skin of your belly. The surgeon gradually tightens the band to restrict the amount of food you can eat.
