Post-nasal drip, asthma, or reflux often cause chronic coughs

A persistent cough, lasting over eight weeks in adults, is most commonly caused by post-nasal drip, asthma, or acid reflux. These conditions often co-occur, potentially exacerbating the cough. Other causes include coughs lingering after respiratory infections and less common conditions like cough-variant asthma. A doctor will consider symptoms like shortness of breath to rule out serious conditions. Treatments include saline sprays, steam inhalation, and honey. Seek medical attention if you cough up blood or experience other concerning symptoms, as a persistent cough can sometimes indicate a more serious underlying issue.
