Bariatric procedures we perform

The Center for Weight Loss Surgery provides several options to meet your specific needs. Talk to your surgeon to identify the best option for you.

Gastric bypass

Also known as the Roux en-Y gastric bypass, this procedure creates a small gastric pouch and reroutes part of the small intestine. Gastric bypass helps you lose weight by restricting the amount of food that your stomach can hold and by reducing the number of calories your body can absorb. Many consider it the gold standard operation that other surgeries are compared to.

Sleeve gastrectomy

A sleeve gastrectomy, which is more commonly known as the “sleeve,” removes the hormonally active part of the stomach. This causes the remaining tubular segment to restrict the amount of food it takes to feel full.

It offers many of the benefits of the other procedures without much of their side effects. The long-term results of this operation are not clear but appear to be promising.

Gastric band

Laparoscopic adjustable bands are a popular weight loss surgery option. During the procedure, doctors place a silicone ring around the upper stomach. They can adjust the fit of the band over time to allow patients to feel a sense of fullness with less food. A gastric band procedure is completely reversible.

Revisional surgery

Doctors may have to perform revisional weight loss surgery if there is not enough weight loss or if problems occur from the original surgery.
