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.

"Dr. Afaneh is incredible. He performed a complex surgery on me, and is getting ready to perform another very soon. It was a wonderful and warm experience from start to finish. Dr Afaneh always takes the time to go over the details of the surgery (both pre and post), and to answer any questions that I have. This ensured that I had a smooth prep, surgery, and follow-up. It is very rare to find a doctor/ surgeon that combines such personal care for their patient with such an outstanding quality of medical knowledge and care. I highly recommend becoming his patient!"
