Cough
Coughing helps protect your lungs from irritants. While occasional coughs are normal, a persistent cough or one with other symptoms may signal a more serious issue.
Learn About Cough
When things such as mucus, germs or dust irritate your throat and airways, your body automatically responds by coughing. This is an important reflex that protects your airways and lungs.
Diagnosing and Treating Cough
Most coughs caused by a respiratory infection will go away on their own without specific treatment. A cough that doesn't go away after a few weeks will need medical attention.
