What are the most common causes of a persistent cough?
Persistent cough can be caused by problems in the lungs or with problems outside of the lungs. Once your doctor has proven there are no problems with your lungs, the most frequently occurring causes from outside of the lungs include postnasal drip, and gastroesophageal reflux disease (GERD). If you have a persistent cough you should seek medical attention since Doctor Cough Respiratory Support is not intended to diagnose, cure, treat or prevent any disease.
