Washington University School of Medicine is seeking participants for a weight loss study.

The study is for those between 30-100 pounds overweight, Dr. Shelby Sullivan told Fox 2 News. 

The procedure involves placing a silicone dual-balloon system in the stomach during a 30-mintue outpatient procedure. The balloons occupy space to reduce the capacity for food.

Sullivan said the calloons stay in the stomach for six months while participants learn to live a healthier lifestyle with the support of dietitians, doctors and nurses.
