About Us

Weill Cornell Medicine’s comprehensive weight loss surgery program provides long-term solutions for patients who continually struggle with their weight.

Ranked #14 nationwide, Weill Cornell Medicine’s Division of Gastrointestinal Metabolic and Bariatric Surgery is proud to partner with NewYork-Presbyterian, ranked #6 in the nation and #1 in NYC  by US News and World Report.

Our physicians are concerned about how heart disease, high blood pressure, diabetes, arthritis, and even sleep disorders are often the consequences of excessive weight. We understand it can be very challenging, and while many people can succeed in achieving some weight loss, sustaining that weight loss or maintaining optimal weight is often difficult, and for some, impossible. 

To help patients lose weight, we offer counseling, medical obesity screening, surgery, if indicated, and extensive follow-up by an expert team of board-certified bariatric surgeons, including gastric sleeve surgeons, as well as advanced nurse practitioners, physician's assistants, and registered dietitians.

GI Metabolic and Bariatric Surgery in New York

Our world-renowned surgeons have pioneered innovative surgical procedures that are at the forefront of weight-loss techniques, as well as laparoscopic procedures for a broad range of digestive disorders. We specialize in minimally invasive bariatric surgery, enabling our patients to undergo weight-loss procedures that can be performed through small incisions, which facilitates faster recovery. At Weill Cornell Medicine, our weight loss surgery options include gastric bypass surgery and vertical sleeve gastrectomy, all performed at NewYork-Presbyterian, the #1 hospital in NYC 17 years in a row.

Most recently, the American College of Surgeons has accredited NewYork-Presbyterian/Weill Cornell Medical Center as a Center of Excellence in bariatric surgery with the highest possible designation – the first program to be so named in New York State and one of only seven nationwide.

What Our Patients Are Saying

Beth Brill
Talking about Rasa Zarnegar, M.D.

"Dr. Rasa Zarnegar is probably the nicest doctor I have ever met. He is so easy to talk to and seems like he has all the time in the world. I had acid reflux surgery performed by him this past November. Everything went very smoothly and he was readily available to talk to before and after surgery. Sometimes the top doctor in the field ends ups being the nicest. I recommend Dr. Z without any hesitation."
