Weight-Loss/Bariatric Surgery

Weight-loss surgery, known medically as bariatric surgery, is performed on patients who are approximately 100 pounds or more overweight and have been unsuccessful with diet and exercise programs, and weight-loss medications. Someone who is 60–80 pounds overweight may qualify if he or she has a medical condition related to obesity.

Mercy is an accredited center of the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program that offers weightloss surgery with efficacy, efficiency and safety.

Our Bariatric Center offers laparoscopic sleeve gastrectomy, laparoscopic adjustable gastric banding, laparoscopic gastric bypass surgery, single-incision laparoscopic surgery (SILS) and more. Mercy provides more than 600 bariatric surgeries a year.

Shawn M. Garber, MD, chief of bariatric surgery at Mercy, and his colleagues in the New York Bariatric Group, Spencer A. Holover, MD, John D. Angstadt, MD, Eric A. Sommer, MD, Nikhilesh Sekhar, MD, and Jeffrey W. Chiao, MD, have performed thousands of minimally invasive weightloss procedures. In addition to its specially trained bariatric surgery team, the hospital has a dedicated bariatric unit with rooms and accommodations specially designed for post-surgery comfort and privacy.


Mercy Medical Center is the first hospital on Long Island to offer a new even less invasive gastric banding procedure known as Single Incision Laparoscopic Surgery (SILS) that uses just one small opening in the abdomen, through the navel, rather than the five incisions required in traditional techniques. Select Sleeve Gastrectomy patients may also be candidates for SILS.

Seminars offering education and information are offered monthly at New York Bariatric Group, Mineola, NY to those individuals who are contemplating bariatric surgery. See "Free Seminars" page for directions.
