If you are obese or significantly overweight and have been unsuccessful losing weight through diet and exercise, it could be time to consider surgical (bariatric) and endoscopic weight loss therapies. NewYork-Presbyterian’s weight management specialists are leaders in weight loss procedures. Our experts have conducted pivotal research demonstrating the value of these approaches for improving metabolic disorders such as type 2 diabetes, high blood pressure, and high cholesterol and triglycerides. Our teams will carefully assess your health and preferences and match you with the weight loss therapy that is best for you.

A Center of Excellence in Weight Loss Surgery

NewYork-Presbyterian was ranked among the top gastroenterology programs in the nation, according to US News & World Report.

The American College of Surgeons Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) has accredited NewYork-Presbyterian as a Comprehensive Center with Adolescent Qualifications in bariatric surgery.

  • The highest designation. The Bariatric Surgery Center at NewYork-Presbyterian/Weill Cornell Medical Center and the Center for Metabolic and Weight Loss Surgery at NewYork-Presbyterian/Columbia University Irving Medical Center were each awarded the highest possible designation in recognition of our surgeons’ unique ability to offer our patients the best care available. Comprehensive Centers with Adolescent Qualifications are defined by the American College of Surgeons as providing complete specialized care for all patients, including those with the most challenging and complex conditions.
  • LABS participation. We were one of ten clinical centers in the United States to be part of Longitudinal Assessment of Bariatric Surgery (LABS), a National Institutes of Health consortium that evaluates bariatric procedures.

Leaders in Weight Loss Surgery

Our weight loss programs feature renowned experts in the field of weight management. Our world-renowned surgeons have pioneered innovative procedures that are at the forefront of weight loss techniques, as well as laparoscopic procedures for a broad range of digestive disorders. In fact, surgeons from all over the world travel to NewYork-Presbyterian to train under their direction.

Innovators in Metabolic Surgery

Bariatric surgery can dramatically improve type 2 diabetes, high blood pressure, and high lipid levels, and reduce the risk of death. Our investigators demonstrated in research studies that the anti-diabetes effect of certain bariatric procedures — particularly gastric bypass surgery — results from mechanisms that go beyond weight loss, supporting the use of this approach for treating type 2 diabetes.

A Collaborative Team to Help You Lose Weight

Your team includes surgeons, interventional endoscopists, gastroenterologists, endocrinologists (hormone specialists with experience in medical weight loss approaches), registered dietitians, nurses, social workers, and others with the compassion and experience to provide the care you need and support your weight loss goals. We also offer support groups for anyone considering surgery, those who have had surgery, or your family members or friends. If you need to see another medical or surgical specialist, NewYork-Presbyterian has those doctors on staff, too. You can receive all the care you need in one medical center.

Minimally Invasive Surgery for Sustained Weight Loss

We offer the complete range of surgical weight loss procedures, performing them using minimally invasive laparoscopic techniques through small incisions that result in less discomfort after surgery and a speedier recovery. Both NewYork-Presbyterian/Columbia and NewYork-Presbyterian/Weill Cornell are national leaders in robotic weight loss surgery, which enables the surgeon to operate with enhanced visualization, dexterity, and precision and to complete certain movements and maneuvers more effectively. You may be eligible to undergo one or a combination of these operations:

  • Roux-en-Y gastric bypass surgery
  • Sleeve gastrectomy
  • Biliopancreatic diversion with duodenal switch
  • Single anastomosis duodenal ileostomy/switch (SADI/SIPS) procedure
  • Laparoscopic gastric banding
  • Staged or revisional procedures

Endoscopic Weight Loss Procedures

If bariatric surgery is not an option for you and you have a body mass index (BMI) between 30 and 40 (obese, but not significantly overweight), you may be able to have an endoscopic procedure. An interventional endoscopist performs these procedures, inserting a flexible scope through your mouth into your esophagus to perform the procedure in your stomach. These include:

  • Endoscopic gastroplasty ("sleeve" gastroplasty)
  • Intragastric balloon
  • AspireAssist

Clinical Trials

Columbia University and Weill Cornell Medicine are leading international centers for the clinical investigation of obesity and diabetes treatment. Several clinical trials are currently underway. Your doctor will let you know if you are eligible to participate in a clinical trial of an innovative and promising weight loss approach.
