Cough: Causes & When to See a Doctor

السعال

Quick summary

A cough is a natural reflex to clear the airway of irritants and mucus. It may be dry or productive, transient with colds or persistent for weeks. Most coughs are minor and self-limiting, but a chronic cough or one with warning signs deserves medical evaluation.

What is Cough?

Cough is one of the most common symptoms and is a defensive mechanism that protects the lungs. It is classified by duration into acute (less than three weeks), subacute, or chronic (more than eight weeks).

Cough often accompanies the common cold and respiratory infections and gradually improves, but prolonged persistence warrants investigation into the underlying cause.

Possible causes

  • Common cold and viral respiratory infections.
  • Postnasal drip and allergies.
  • Asthma or bronchitis.
  • Gastroesophageal reflux disease (GERD).
  • Smoking or exposure to irritants and smoke.

These are common causes; chronic cough may require medical evaluation to determine the underlying cause.

When to see a doctor

Consult your doctor if:

  • Cough persists for more than two to three weeks.
  • It is accompanied by thick colored sputum or persistent fever.

Seek emergency care immediately if cough is accompanied by blood, severe shortness of breath, chest pain, or bluish lips.
