A chronic cough is defined as a cough lasting eight weeks or longer. Many underlying causes can cause chronic cough. However, in most cases, if the underlying cause is treated, the chronic cough will disappear.

Chronic cough can affect a person both physically and mentally. Conditions such as insomnia and urinary incontinence that come with chronic cough can significantly affect the daily life of the person. In severe cases of chronic cough, it can cause vomiting, dizziness and fainting.

Chronic cough is more common in smokers.
