Dr. Blair Lewis is a well-respected and experienced New York City gastroenterologist providing care for all sorts of gastrointestinal diseases and conditions at his private practice on Manhattan's Upper East Side. As a board-certified gastroenterologist with more than 72 scientific papers, 25 book chapters and three books to his credit, Dr. Lewis is skilled in a wide array of procedures and treatments aimed at diagnosing and treating GI issues, including endoscopy, colonoscopy, capsule endoscopy and colon cancer screening, as well as the care and management of diseases and conditions like gastroesophageal reflux disease (GERD), colonic polyps and inflammatory bowel disease (IBD). He is considered to be one of the world's leading experts in endoscopy and is widely considered to be the “father” of the capsule endoscopy technique, having served as the primary investigator of several early clinical trials.
Dr. Lewis received his M.D. From Albert Einstein College of Medicine, performing his residency in internal medicine at Montefiore Medical Center and a fellowship in internal medicine at Mount Sinai Hospital. In addition to his private practice, Dr. Lewis holds a faculty appointment at Mount Sinai Hospital and is a clinical professor of medicine at the Icahn School of Medicine at Mount Sinai. Named one of New York City's 100 best doctors, Dr. Lewis has been featured on CNN, NBC and CBS Nightly Newscasts, ABC’s 20/20, and NBC’s The Today Show.
Dr. Lewis also chaired the annual International Conference of Capsule Endoscopy, and he is past president of the New York Society for Gastrointestinal Endoscopy and the New York Academy of Gastroenterology. He teaches courses in capsule endoscopy nationally and internationally.
Committed to providing each patient with the information he or she needs to make educated, informed treatment decisions, Dr. Lewis offers one-on-one gastroenterology consultations to provide information about care, answer questions and address concerns. Each plan of treatment is carefully developed, taking multiple factors into account to ensure the best possible outcome based on every patient's unique medical needs and overall health.
Dr. Lewis welcomes new patients, and his practice accepts most major forms of medical insurance.
