Laryngopharyngeal Reflux

Laryngopharyngeal reflux (LPR), also extraesophageal reflux disease (EERD) refers to retrograde flow of gastric contents to the upper aero-digestive tract, which causes a variety of symptoms, such as cough, hoarseness, and asthma, among others.

Although heartburn is a primary symptom among people with gastroesophageal reflux disease (GERD), heartburn is present in fewer than 50% of the patients with LPR. Other terms used to describe this condition include atypical reflux, and supraesophageal (or supra-esophageal) reflux.
