GI Metabolic and Bariatric Surgery

Comprehensive and Personalized Surgical Support for Your Health and Well-Being

The Weill Cornell Medicine Gastrointestinal (GI) Metabolic and Bariatric Surgery Program provides the most advanced diagnostic and surgical techniques. We are a highly skilled, compassionate team of surgeons dedicated to helping you enjoy the best possible health.

GI metabolic and bariatric surgery is a field of surgery for treating gastrointestinal conditions (conditions that affect any organ in the digestive system) and type 2 diabetes, as well as promoting weight loss.

All surgeons at Weill Cornell Medicine — including our GI metabolic and bariatric surgeons — use the most advanced techniques and technology to provide comprehensive care for our patients. We work with specialized nutritionists and a medical weight loss specialist.

Each of our doctors is a highly accomplished surgeon who prioritizes patient care and well-being. Many are leaders in their fields or are the nation’s top experts in their subspecialty. Our team is invested in ensuring your optimal health and are involved from initial diagnosis to follow-up and recovery.

We understand that the decision of whether to undergo surgery is highly personal. Our team is dedicated to helping our patients understand their health and options, so that you feel confident in making decisions about your care and health.

All treatment is personalized to help you achieve your unique health goals. In addition, Weill Cornell Medicine is dedicated to helping you thrive after surgery with support groups and integrative health services.

If surgical treatment is the best option for you, our team provides the most advanced techniques and options, including:

• Laparoscopic and robotic bariatric surgery, which uses the most advanced techniques to perform weight loss surgery
• Metabolic surgery to promote long-lasting remission for type 2 diabetes
• Minimally invasive gastrointestinal surgery, which benefits patients with a faster recovery time and less pain than traditional surgical options
