| Type | Duration | Common Causes |
|---|---|---|
| Acute | < 3 weeks | Respiratory tract infection (viral URTI, cold), aspiration, smoke inhalation |
| Subacute | 3–8 weeks | Post-viral tussive syndrome, pertussis, post-tracheobronchitis |
| Chronic | > 8 weeks | Asthma, GERD, post-nasal drip, COPD, TB, malignancy, ACE inhibitor use |
Key principle: Treating the root cause is always more effective than suppressing the cough alone. Cough is a protective reflex — in productive (wet) cough, suppression may not always be appropriate.
