The 8-Week Rule: Understanding Chronic Coughs
Key Information
- The Definition: A cough that has lasted for longer than 8 weeks is known as a chronic cough.
- The Warning Light: Think of a chronic cough like a warning light on a car dashboard. It signals that something may need professional investigation.
- Viral vs. Chronic: Unlike a short-term cough caused by a passing virus, a chronic cough often needs the underlying cause to be identified and treated.
Common Causes We Investigate
To turn off the “warning light,” we need to understand what is triggering the cough. Common causes include:
- Asthma: Often linked with wheezing, breathlessness, or coughing at night or after exercise.
- Acid Reflux: Stomach acid can travel upwards and irritate the throat.
- Postnasal Drip: Mucus dripping down from the back of the nose can irritate the throat.
- COPD: Chronic Obstructive Pulmonary Disease is more common in people who smoke or have smoked in the past.
What Happens Next?
You should not just “put up with” a cough that has lasted for months.
The best way to treat it is to find the cause. We will listen to your symptoms, examine you, and arrange tests if needed.
If you have had a cough for more than 8 weeks, please contact us.
