Mount Sinai's Center for Gastrointestinal Physiology and Motility is the largest center of its type in New York City and one of a handful in the country offering advanced diagnostics and treatment for patients with often-complex motility disorders. The Center’s expertise, advanced technology, and reputation consistently draw referrals from gastroenterologists throughout the region for patients with conditions affecting the intestinal tract, from common ones such as gastroesophageal reflux disease and dysphagia to rare ones such as achalasia, gastroparesis, and chronic intestinal pseudo-obstruction.
