Management of chronic cough relies on identification and treatment of the background disorder maintaining the cough. Asthma, upper airway cough syndrome (UACS, previously called postnasal drip syndrome or chronic rhinosinusitis), and gastroesophageal reflux disease (GERD) are the most common background disorders in chronic cough [1].FootnotesThis manuscript has recently been accepted for publication in the ERJ Open Research.
