True or false health: a cough that lasts more than three weeks is always linked to a cold?
A cough that lasts more than three weeks is not always synonymous with a cold. Other factors may be at play, sometimes requiring medical consultation.

Verdict: FALSE.

A cough can have many origins

After a viral infection, it is not uncommon for a cough to persist for several weeks. The airways remain irritated and sometimes take time to return to normal functioning.

But this explanation is not the only one.

A chronic cough can also be linked to gastroesophageal reflux, asthma, certain allergies or even smoking.

Certain medications are also known to cause a persistent cough.

Signs that should alert

A cough accompanied by blood, severe shortness of breath, unexplained weight loss or chest pain requires rapid consultation.

Likewise, a cough that does not improve despite several weeks of progression deserves a medical check-up.

Why you shouldn’t wait too long

A prolonged cough is not necessarily serious, but it is a symptom which sometimes requires additional examinations to determine its origin.

Treatment depends entirely on the cause identified.

What to remember

Not all prolonged coughs are due to a simple cold. When they persist, they must be evaluated to understand their origin.

Advice from Dr Gérald Kierzek

In a smoker, a chronic cough warrants a medical assessment with at least a chest CT scan. In non-smokers, a chronic cough mainly suggests a runny nose, GERD, asthma or eosinophilic bronchitis, and also requires medical advice if it persists.
