What Is Bronchitis?
Bronchitis is the inflammation of the bronchial tubes, which carry air to and from your lungs. When these tubes become inflamed, they produce excess mucus, leading to coughing and difficulty breathing.
Types of Bronchitis
- Acute Bronchitis
- Duration: Short-term (usually less than 3 weeks)
- Cause: Often due to viral infections (like a cold or flu)
- Symptoms: Can resemble a common cold, then worsen into a persistent cough
- Chronic Bronchitis
- Duration: Long-term, recurring (at least 3 months/year for 2 consecutive years)
- Cause: Long-term irritation (commonly smoking)
- Associated with: Chronic Obstructive Pulmonary Disease (COPD)
Symptoms
- Persistent cough with mucus (clear, yellow, or green)
- Wheezing
- Shortness of breath
- Chest discomfort
- Fatigue
- Mild fever and chills (mainly in acute cases)
- Sore throat
Causes
For Acute Bronchitis:
- Viruses (90% of cases)
- Bacteria (rarely)
- Irritants: dust, fumes, smoke
For Chronic Bronchitis:
- Cigarette smoking (most common cause)
- Long-term exposure to:
- Air pollution
- Toxic gases or chemicals (e.g., in the workplace)
Diagnosis
- Medical history & physical exam
- Listening to lungs (with a stethoscope)
- Tests may include:
- Chest X-ray
- Sputum test
- Pulmonary function tests (spirometry)
Treatment
For Acute Bronchitis:
- Supportive care:
- Rest
- Hydration
- Humidifiers
- Medications:
- Cough suppressants (for sleep)
- NSAIDs (e.g., ibuprofen)
- Antibiotics (only if bacterial cause is suspected)
For Chronic Bronchitis:
- Stop smoking
- Bronchodilators (inhalers)
- Steroids (inhaled or oral)
- Pulmonary rehabilitation
- Oxygen therapy (for advanced cases)
Prevention
- Avoid smoking
- Get vaccinated:
- Flu shot
- Pneumococcal vaccine
- Wash hands regularly
- Avoid contact with sick individuals
- Wear masks in polluted or high-risk areas

- Bronchitis vs. Pneumonia vs. Asthma
Feature | Bronchitis | Pneumonia | Asthma |
Cause | Viral (mainly), bacterial, irritants | Mostly bacterial or viral | Chronic inflammation & narrowing of airways |
Main Site Affected | Bronchial tubes (airways) | Alveoli (air sacs in lungs) | Bronchi (airways) |
Mucus | Yes, often thick | Sometimes, usually less | Often minimal, clear |
Fever | Mild (mainly in acute) | High | Rare |
Shortness of Breath | Mild to moderate | Moderate to severe | Common, especially during attacks |
Wheezing | Sometimes | Rare | Common |
Onset | Gradual (like a cold) | Sudden or after illness | Triggered by allergens, exercise, etc. |
- Natural Remedies and Home Treatments
These are helpful for acute bronchitis or managing chronic bronchitis symptoms:
Remedies:
- Steam Inhalation: Loosens mucus
- Honey + Warm Water: Soothes sore throat & cough
- Ginger or Turmeric Tea: Anti-inflammatory effects
- Saltwater Gargle: Relieves throat irritation
- Humidifier: Keeps air moist, reduces irritation
Avoid:
- Smoking
- Cold, dry air (use a scarf or mask)
- Overuse of cough suppressants (can trap mucus)
- Medications for Bronchitis
For Acute Bronchitis:
- Cough suppressants (e.g., dextromethorphan): Only for dry cough or to help sleep
- NSAIDs (e.g., ibuprofen): For pain/fever
- Antibiotics: Only if bacterial infection is confirmed or suspected
For Chronic Bronchitis (COPD-related):
- Bronchodilators (inhalers): Open airways (e.g., albuterol)
- Inhaled corticosteroids: Reduce inflammation (e.g., fluticasone)
- Oral steroids: For flare-ups (e.g., prednisone)
- Oxygen therapy: For advanced disease
- Mucolytics: Help thin mucus
- Impact of Smoking on Chronic Bronchitis
- Smoking is the #1 cause of chronic bronchitis.
- It leads to:
- Permanent airway damage
- Increased mucus production
- Decreased cilia function (clears mucus)
- Quitting smoking is the most effective way to prevent progression to COPD.
- Lifestyle Changes & Long-Term Management
For chronic bronchitis:
Changes:
- Quit smoking or avoid secondhand smoke
- Exercise regularly to improve lung capacity
- Use a humidifier at home
- Avoid cold air and environmental pollutants
Management:
- Pulmonary rehabilitation: Exercise + breathing therapy
- Vaccines: Annual flu shot and pneumococcal vaccines
- Regular monitoring: Lung function tests, especially for COPD patients
- Diagnosis and Testing
Initial Evaluation:
- Medical history (smoking? asthma? recent illness?)
- Physical exam with stethoscope
Tests:
- Chest X-ray: Rules out pneumonia
- Sputum test: Checks for bacterial infection
- Spirometry: Measures lung function (key for chronic bronchitis or COPD)
Pulse oximetry: Measures oxygen levels
Bronchitis in Children vs. Adults
Feature | Children | Adults |
Common Cause | Viral infections (cold, RSV) | Viral or smoking-related |
Risk Factors | Immature immune system, daycare exposure | Smoking, pollution, workplace exposures |
Symptoms | Cough, wheezing, low fever, crankiness | Cough, chest discomfort, fatigue |
Treatment | Supportive care, rarely meds | Depends on type (may include inhalers, steroids) |
Important: In children, wheezing + cough could also signal asthma, not just bronchitis.
Summary Quick Table
Category | Acute Bronchitis | Chronic Bronchitis |
Duration | <3 weeks | ≥3 months/year (for ≥2 years) |
Cause | Viral, irritants | Smoking, pollution |
Treatment | Supportive, rarely meds | Inhalers, steroids, rehab |
Contagious? | Yes (if viral) | No |
Risk of COPD? | No | Yes |
