Bronchitis and pneumonia both affect the respiratory system, but they’re distinct conditions that target different parts of your lungs and vary in severity.
Bronchitis is an inflammation of the bronchial tubes—the airways that carry air to your lungs. It primarily affects the bronchial lining, causing swelling and mucus production. Most cases are caused by viruses and resolve with rest and supportive care. The hallmark symptom is a persistent cough that often produces mucus.
Pneumonia, on the other hand, is an infection of the lung tissue itself, specifically the tiny air sacs (alveoli) where oxygen exchange occurs. These air sacs fill with fluid or pus, making breathing difficult and oxygen exchange less efficient. Pneumonia can be caused by viruses, bacteria, or fungi, with bacterial pneumonia often requiring antibiotic treatment.
Key differences include:
- Location: Bronchitis affects the airways; pneumonia affects the lung tissue
- Severity: Pneumonia is typically more serious and can be life-threatening
- Symptoms: Both cause cough, but pneumonia more often produces high fever, severe chest pain, and significant breathing difficulty
- Treatment: Bronchitis usually requires only supportive care, while pneumonia often needs medical intervention and sometimes hospitalization
- Recovery time: Bronchitis typically resolves in 1-3 weeks; pneumonia may take 4-6 weeks or longer
