If your cough doesn't go away even after three weeks or more, you should see a pulmonologist. A persistent cough can have a wide range of causes, some minor and some that need medical attention.
When to Seek Medical Attention
Consult a physician if a persistent cough is accompanied by fever, coughing up blood, unexplained weight loss, fatigue, or breathing difficulties.
Common Causes
- Common cold — typically resolves within days; seek care if symptoms persist beyond 10 days
- Bronchitis — inflammation causing a mucus-productive cough with weakness and body pain
- COPD — smoking-related lung disease causing wheezing and shortness of breath
- Pneumonia — lung infection with fever, chest pain, and appetite loss
- Asthma — triggers nighttime coughing, wheezing, and chest discomfort
- Allergies — immune overreaction to environmental irritants; severe cases may cause anaphylaxis
