Bronchitis is inflammation of the bronchial tubes that carry air to the lungs. Acute bronchitis usually follows a cold or flu and causes a persistent with mucus, chest discomfort, and sometimes mild . Most cases are viral and resolve within 2–3 weeks with home care. Chronic bronchitis — cough lasting months, often in smokers — needs long-term medical management. Home treatment focuses on easing cough, thinning mucus, and preventing complications such as pneumonia, especially in polluted Indian cities where air quality can worsen symptoms.
Acute vs Chronic Bronchitis
- Acute bronchitis — sudden cough after upper respiratory infection; may produce clear, yellow, or green mucus; usually self-limiting
- Chronic bronchitis — productive cough most days for at least 3 months per year for 2 consecutive years; linked to smoking and long-term pollution exposure
- Bacterial overlap — true bacterial bronchitis is uncommon; green phlegm alone does not always mean antibiotics are needed
- Whooping cough, TB, asthma — can mimic bronchitis; prolonged or severe cough needs medical evaluation
Evidence-Based Home Care Steps
Clinical guidance from NHS[1] stresses matching home care to symptom severity and seeking urgent review when red-flag signs appear.
What to Avoid
- Antibiotics without doctor confirmation — most acute bronchitis is viral
- Heavy suppressant use when thick mucus needs clearing — unless doctor advises
- Exercising in high AQI pollution without protection
- Giving adult cough medicines to young children without paediatric guidance
- Ignoring cough lasting more than 3 weeks
When to See a Doctor
- Cough lasting more than 3 weeks or worsening after initial improvement
- High fever, night sweats, or unintentional weight loss — rule out TB
- Known asthma, COPD, heart failure, or immunosuppression
- Wheezing or breathing difficulty not relieved by rest
- Infants, elderly, or pregnant women with persistent symptoms

Frequently Asked Questions
Do I need antibiotics for bronchitis?

Why is my cough worse at night?
Lying flat allows mucus to pool and post-nasal drip to trigger coughing. Dry air, , and bedroom dust mites also play a role. Elevating the head, using a humidifier, and avoiding late heavy meals may help.
How long does bronchitis cough last?
Acute bronchitis cough often persists 2–3 weeks even after other symptoms improve — this is common and frustrating but usually normal. Cough beyond 3 weeks warrants medical review.
Can bronchitis turn into pneumonia?
Yes, especially in elderly, very young, or chronically ill patients. include high fever, rapid breathing, sharp , and . Early medical assessment reduces complication risk.
