A cough is your body's response to something that bothers your throat or airways. Many things can cause a cough. You might cough because of a cold or the flu, bronchitis, or asthma. Smoking, post-nasal drip, allergies, and stomach acid that backs up into your throat also can cause a cough.
A cough can be short-term (acute) or long-term (chronic). A chronic cough lasts more than 3 weeks. A chronic cough is often caused by a long-term problem, such as asthma. Another cause might be a medicine, such as an ACE inhibitor.
