Summary

This study investigates whether chronic cough lasting more than a year can injure and remodel the lower airways. Researchers will use chest CT scans and bronchoscopy to look for signs of airway damage and inflammation in adults with refractory chronic cough. The goal is to understand if the cough itself causes structural changes in the lungs.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to: If chronic cough is shown to cause airway damage, this could lead to earlier treatments to prevent long-term lung changes.
What could go wrong: This is a small observational study, so it may not prove cause and effect. Results may not apply to all people with chronic cough.
