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.
