Bariatric surgery procedures

Our bariatric surgeons perform laparoscopic sleeve gastrectomies, where 75% of the stomach is removed and takes on the shape of a sleeve. This is a minimally invasive surgery.

They also perform the roux-en-y gastric bypass surgery, where a very small stomach is created during surgery.

Patients who undergo this procedure may be hospitalized for several days but can lose about 65 to 70% of their excess weight on average within 18 months of surgery.

Continued support after bariatric surgery

Following surgery, we're just a phone call away! To assist you as you recover, our bariatric support group meets the first and third Thursday. We welcome current patients, family members, and anyone who has undergone or is considering weight-loss surgery.
