Understanding chronic coughs

Key Information:

      The Definition: A cough that has lasted for longer than 8 weeks is classified as a "chronic cough."

      The Warning Light: Think of a chronic cough like a warning light on a car's dashboard. It is a signal from your body that there is an underlying issue that needs professional investigation.

      Viral vs. Chronic: Unlike a short-term cough (usually caused by a passing virus), a chronic cough rarely clears up on its own without treating the root cause.

Common Causes We Investigate

To turn off the "warning light," we need to identify what is triggering the cough. Common causes include:

1.     Asthma: Often accompanied by wheezing or shortness of breath.

2.     Acid Reflux: Where stomach acid travels up and irritates the throat.

3.     Postnasal Drip: Mucus dripping down from the back of the nose, irritating the throat.

4.     COPD (Chronic Obstructive Pulmonary Disease): This is very common in people who smoke or have smoked in the past.
