Overview
Bronchitis is inflammation of the airways that carry air to the lungs, often causing a cough. This is general educational information, not medical advice.
Symptoms
- persistent cough, sometimes bringing up mucus
- mild chest discomfort
- tiredness
- mild fever in acute cases
Causes
- viral respiratory infections (acute bronchitis)
- long-term irritant exposure such as tobacco smoke (chronic bronchitis)
Risk factors
- tobacco smoke or air-pollution exposure
- recent respiratory infection
Prevention
- avoiding tobacco smoke and irritants
- hand hygiene and recommended vaccinations
Evaluation & tests
Educational note: clinicians usually assess bronchitis from symptoms and examination; tests are added when another condition is suspected. This library does not diagnose.
Treatment education
Educational overview: acute bronchitis is often self-limiting and care focuses on rest, fluids, and symptom relief guided by a clinician. This library does not prescribe.
Self-care
General education: rest, staying hydrated, and avoiding irritants can support recovery; seek review if symptoms persist.
When to seek care
Seek professional care if a cough lasts more than three weeks, breathing becomes difficult, or a high fever develops.
