Q&A: Reducing the stomach without surgery

Dr. Christopher Chapman

A new alternative to traditional obesity surgery can help you jump-start your weight loss. The University of Chicago Medicine is the first hospital in Chicago offering the nonsurgical procedure to shrink the size and volume of the stomach.

Christopher Chapman, MD, is director of metabolic and bariatric endoscopy and a member of the Center for Endoscopic Research and Therapeutics at the University of Chicago Medicine. He answers your questions about endoscopic sleeve gastroplasty (ESG), which can help patients lose nearly 20 percent of their total body weight.

Who is a good candidate for endoscopic sleeve gastroplasty (ESG)?

ESG and other endoscopic therapies for weight loss are designed for patients with a body mass index (BMI) between 30 and 40. However, our team evaluates patients on a case-by-case basis to determine their best option for achieving weight loss and will consider patients with higher BMIs.

What happens during the procedure?

While the patient is asleep, we thread a flexible tube--called an endoscope--through the mouth, down the esophagus and into the stomach. Using a device attached to the endoscope, we stitch and tighten sutures that constrict the stomach, reducing it to the size of a banana. The procedure takes about an hour and most patients go home the same day.

What kind of results can patients expect?

Changes in lifestyle and diet are always the most important factors in maximizing weight loss. In the first three to six months, patients can expect to lose 10 to 15 percent of their total body weight. Typical weight loss in the first two years after an ESG procedure ranges from 30 to 60 pounds.
