Published Online: January 16, Although most people think acid reflux only causes heartburn, there is a growing interest in another form of reflux, which causes mostly respiratory symptoms. This form of reflux, known as supraesophageal reflux disease SERD or laryngopharyngeal reflux LPR , is caused by acid from the stomach regurgitating into the throat, mouth, nasal passages, and even the lungs, resulting in symptoms such as chronic cough, hoarseness, sinusitis, and tooth decay. Supraesophageal reflux can be challenging to diagnose and treat, in part because it often goes unrecognized. Also, unlike heartburn-causing reflux, SERD often does not respond to antacid medications, making treatment a challenge. David Scott and Ronald Simon explored the prevalence and timing of SERD and investigated the efficacy of head-of-bed elevation in its treatment.
