SpecialtyGastroenterology

Laryngopharyngeal reflux (LPR) or laryngopharyngeal reflux disease (LPRD) is the retrograde flow of gastric contents into the larynx, oropharynx and/or the nasopharynx.[4][5] LPR causes respiratory symptoms such as cough and wheezing[6] and is often associated with head and neck complaints such as dysphonia, globus pharyngis, and dysphagia.[7] LPR may play a role in other diseases, such as sinusitis, otitis media, and rhinitis,[7] and can be a comorbidity of asthma.[6] While LPR is commonly used interchangeably with gastroesophageal reflux disease (GERD), it presents with a different pathophysiology.[8]

LPR reportedly affects approximately 10% of the U.S. population. However, LPR occurs in as many as 50% of individuals with voice disorders.[9]
