Cough: causes, types and when to consult a doctor

I am Dre Aurélia Nha-Huyen Nguyen Gouez, a family physician and medical director of French origin. After practicing in France, I settled in Quebec where I worked in a CLSC before moving into private medicine. My goal with Allodocteur.ca is to offer accessible, fast, and compassionate medical consultations, particularly through home visits.

A cough is a common symptom that can be benign or reveal an underlying health problem. It can be acute (less than 3 weeks) or chronic (more than 8 weeks). But when should you be concerned and consult a doctor?

Why do we cough?

Coughing is a natural reflex aimed at protecting the airways. It can be triggered by:

• A viral or bacterial infection: cold, flu, COVID-19, bronchitis, pneumonia.

• Allergies or irritants: pollen, smoke, dry air, pollution.

• Gastroesophageal reflux disease (GERD): acid reflux irritating the throat.

• Asthma or a chronic respiratory disease.

• Certain medications, such as ACE inhibitor antihypertensives.

If your cough persists or becomes bothersome, it is best to identify the cause with a healthcare professional.

Signs that should lead you to consult

Although a cough is often benign, certain signs should be alerting:

✅ Cough lasting more than 3 weeks without improvement.

✅ Persistent fever (over 38.5°C) and significant fatigue.

✅ Shortness of breath, chest pain or wheezing.

✅ Coloured phlegm (green, dark yellow) or the presence of blood.

✅ Cough that worsens at night or disrupts sleep.

In these cases, it is better not to wait and consult a doctor.

At Allodocteur.ca, we offer home medical consultations to save you from travelling and long waits in clinics.
