What is Laryngopharyngeal Reflux Disease (LPRD)?
When we eat something, the food reaches the stomach by traveling down a muscular tube called the esophagus. Once food reaches the stomach, the stomach adds acid and pepsin (a digestive enzyme) so that the food can be digested. The esophagus has two sphincters (bands of muscle fibers that close off the tube) that help keep the contents of the stomach where they belong. One sphincter is at the top of the esophagus (at the junction with the upper throat) and one is at the bottom of the esophagus (at the junction with the stomach). The term REFLUX means “a backward or return flow,” and it usually refers to the backward flow of the stomach contents up through the sphincters and into the esophagus or throat.
