Causes and signs of a chronic cough

Overview

Coughing can be unpleasant at times, but it actually serves a useful purpose. When you cough, mucus and foreign substances come out of the airways, which can irritate the lungs. A cough can be a response to inflammation or illness.

Most coughs are short-lived. You get a cold or the flu, cough for a few days or weeks, and then start to feel better.

In most cases, the cough lasts for weeks, months, or even years. If you’re coughing for no apparent reason, you may have something serious going on.

A cough that lasts eight weeks or longer is called a chronic cough. Even chronic coughs are usually treatable. These can be caused by conditions such as post-nasal drip or allergies. Only in rare cases are they signs of cancer or other potentially life-threatening lung conditions.

A chronic cough can have a significant impact on your life. It can keep you up at night and distract you from work and social life. This is why you should see a doctor if you have a cough that lasts more than three weeks.
