Esophageal Motility Disorders and Gastroesophageal Reflux Disease

Esophageal motility disorders and esophageal reflux are common, produce a wide range of symptoms, and compromise quality of life. Neural and muscle-based mechanisms contribute to altered function of the lower esophageal sphincter, creating problems if it is too relaxed or too constricted. Improvements in diagnosis and treatment have improved the management of these disorders.
