What is Bariatric Surgery?

If you have obesity, bariatric surgery can help you get to and maintain a healthier weight and more active lifestyle. However, it is not a quick fix. Bariatric surgery is a part of your weight loss journey, the other part requires a lifelong commitment to a healthy lifestyle. 

Bariatric Surgery Overview

At the Penn Bariatric and Weight Loss Surgery Program, we're committed not only to helping you achieve your weight loss goals, but also to improving your overall health. And the benefits of bariatric surgery are vast. It can improve your quality of life, reverse diabetes, eliminate sleep apnea, help control high blood pressure and reduce the risk of heart disease. 

Under the leadership of Noel Williams, MD, FRCSI, director, our team of professionals — experts in their respective fields of nursing, nutrition, psychology and surgery — will guide you along your entire weight loss journey. The team works together to provide you with the highest quality of care, from the time of your free information session and support groups, to the day of your bariatric surgery and long-term followup care both in-office at at your fingertips with our LifeGained app.
