About Us

The Weill Cornell Medicine GI Metabolic and Bariatric Surgery Program is dedicated to providing the most advanced diagnostic and surgical techniques to help you to accomplish your individual health goals.

The decision about whether to undergo surgery is often complex and very personal, which is why our team of world-renowned surgeons and clinicians provide individualized care alongside the latest advances in medicine.

Our specialties include:

  • Laparoscopic and robotic bariatric surgery, which uses the most advanced techniques to perform weight loss surgery
  • Metabolic surgery, which aims to put type 2 diabetes into long lasting remission
  • Minimally invasive gastrointestinal surgery, which addresses a broad variety of disorders, ranging from hernias to problems that arise in the stomach, gall bladder, esophagus and intestine
  • Medical weight management:¬†intensive medical treatment for obesity including lifestyle counseling, individualized nutrition and physical activity recommendations, and medication management.

Our use of cutting-edge, minimally invasive methods means small incisions, a short hospital stay (if any), and a quicker recovery from your operation. All surgery is performed at NewYork-Presbyterian, the #1 hospital in New York City for 17 years in a row. 

In addition to our surgical expertise, we also offer nutritional guidance and support groups as part of our comprehensive approach.

What Our Patients Are Saying

Suzanne Madden

"My husband got a referral to see Dr. Afaneh and he is so glad he was able to see him. He has given him hope that he will be able to finally once and for all get rid of his meds for his Hyena hernia and ulcers in his esophagus that he has been suffering from for 20 years. Dr. Afaneh was extremely professional and knowledgeable with this field and we feel that my husband is in the right hands with taking care of him. The nurse practitioner Natasha is so very nice and is there to answer any of you questions and concerns you may have. She went out of her way to make sure my husband Mike knew exactly what he needed to do before his procedure. I would highly recommend them to my family and friends."

Talking about Rasa Zarnegar, M.D.

"From the front desk everyone was very professional and very polite the place looks great and the doctors are wonderful. I did wait a little bit before I could see doctor Zarnegar but I didn't mind. My only issue was with the room temperature it was a little bit too low but I love the place and I highly recommend it."
