What is it?
Chronic cough is a clinical condition typically defined by coughing that has lasted for longer than 2 months. There are a number of potential causes of chronic cough, including laryngopharyngeal reflux, asthma, certain medications, sensory disorders, or structural lesions of the esophagus, larynx, or trachea.
How is it treated?
Chronic cough may be caused by an underlying disorder that is treated based on history and physical exam with certain medications. A thorough diagnostic work-up may be required if unable to identify a cause, which can include office-based evaluations of the esophagus, larynx, and trachea, imaging, and consultation with other specialists. Patients may be candidates for various medical therapies based on specific underlying disorders.
