What is bronchitis?
Bronchitis is inflammation of the bronchial airways. Acute bronchitis often follows a viral infection, while persistent cough needs separate assessment.
Causes, symptoms and diagnosis
1. Definition and causes Acute bronchitis irritates airways and causes cough; smoke can worsen it. Chronic bronchitis is considered separately in the context of COPD. 2. Symptoms and assessment Cough, mucus, mild chest discomfort and tiredness can occur. Duration, fever and breathing are assessed; pneumonia or asthma may need investigation. 3. Care and treatment Rest, fluids and symptom monitoring often suffice in acute cases. Antibiotics do not treat viruses and are not automatic; personal medical factors matter.
Warning signs and prevention
4. When to seek help Breathlessness, blood in sputum, persistent fever, severe chest pain, deterioration or prolonged cough warrant medical evaluation. 5. Prevention and daily life Avoiding tobacco smoke, hygiene and recommended vaccines support respiratory health. Persistent productive cough needs a search for underlying disease.
