Long-term weight loss begins here.

If diet and exercise have not worked for you in the past, weight loss surgery - also known as bariatric surgery - may be an option. Bariatric surgery is the most effective tool to date for achieving significant long-term weight loss.

At the Comprehensive Bariatric Surgery Program at Crozer-Chester Medical Center, we believe reaching and maintaining a healthy weight is a lifelong commitment. We’re here to help you every step of the way.

Our program has been recognized as a Center of Excellence by the American Society for Metabolic & Bariatric Surgery (ASMBS). We were also recognized for having one of the lowest rates of potentially avoidable complications (PACs) in the country by Blue Health Intelligence.


Crozer-Chester Medical Center is one of the first in the area to offer bariatric surgery with the use of the da Vinci® minimally invasive robotic surgical system. Learn about your eligibility and what this type of surgery entails in the article below.
