Esophageal Motility Disorders
The esophagus is a tube-shaped muscle that connects the mouth to the stomach. It resides mostly in the chest behind the trachea and heart with short segments in the neck and abdomen. The esophagus provides coordinated pushing (motility) of swallowed food or drink from the mouth into the stomach. An esophageal motility disorder occurs when food doesn’t move properly down the esophagus; several types of motility disorders exist.
