What is Bariatric Surgery?

Bariatric surgery includes a variety of surgical procedures designed to induce significant weight loss. The two most common procedures done in the country and at Lowell General Hospital are the gastric bypass and the sleeve gastrectomy.

The gastric bypass operation involves stapling the stomach into a small pouch and rerouting a portion of the intestine. By having food bypass the remainder of the stomach and a portion of the intestine, smaller amounts of food are eaten and less of that food is absorbed by the body. The
sleeve gastrectomy involves removing about 80% of the stomach, restricting the amount of food that can be eaten.

With significant weight loss, we also expect to see improvements in several obesity-related medical problems, such as diabetes, hypertension, high cholesterol, and sleep apnea.
