title: Is reflux cough due to gastroesophageal reflux disease or laryngopharyngeal reflux?
abstract: Reflux is a common cause of chronic cough. Surveys of patients with chronic cough point to a high association with gastroesophageal disease. Because of our bipedalism and speech, humans are prone to both reflux and aspiration. Whether the reflux of stomach contents into the esophagus alone is sufficient to cause cough or whether reflux into the upper airway is required is unknown. In 50 consecutive patients with chronic cough, symptoms of laryngopharangeal reflux (LPR) paralleled those of gastroesophageal reflux, suggesting no unique syndrome of LPR but that it is part of the protean manifestations of reflux disease.
