What is Bronchitis?
Bronchitis is inflammation of the bronchi, the large airways that carry air to your lungs. This inflammation causes swelling and mucus production, which can lead to cough, chest discomfort, and difficulty breathing.
Bronchitis can be acute (short-term, usually a few weeks) or chronic (long-term, recurring episodes, often related to smoking or lung disease). Both adults and children can develop bronchitis.
What Causes Bronchitis?
Infections
- Viral infections such as colds or flu are the most common cause
- Bacterial infections are less common but may occur
Irritants and Lifestyle Factors
- Smoking or exposure to second-hand smoke
- Air pollution
- Dust, chemical fumes, or other respiratory irritants
- Allergies
Chronic Bronchitis
- Long-term inflammation, usually linked to smoking or chronic obstructive pulmonary disease (COPD)
- More common in older adults or those with repeated respiratory infections
What Are the Common Symptoms of Bronchitis?
- Persistent cough (often producing mucus)
- Chest tightness or discomfort
- Shortness of breath, especially on exertion
- Fatigue
- Mild fever or chills (more common in acute cases)
- Sore throat
- Wheezing or noisy breathing
How Is Bronchitis Diagnosed?
Diagnosis is usually based on symptoms and a physical examination.
During an online GP consultation we can:
- Assess your symptoms and medical history
- Determine whether your bronchitis is likely viral, bacterial, or chronic
- Advise on symptom relief and management
- Provide private prescriptions when appropriate
- Recommend whether an in-person examination or chest imaging is needed
You may need an in-person assessment if symptoms are severe, persistent, or there are red-flag signs such as high fever, rapid breathing, or chest pain.
How Long Does Bronchitis Last?
- Acute viral bronchitis usually improves within 1–3 weeks
- Cough may linger for up to 6 weeks in some cases
- Chronic bronchitis persists for months and may require ongoing management
Is Bronchitis Contagious?
- Acute viral bronchitis can be contagious through coughs, sneezes, and close contact
- Chronic bronchitis and irritant-induced bronchitis are not contagious
How to Feel Better and Recover Quickly
Self-Care at Home
- Rest and avoid overexertion
- Drink plenty of fluids
- Use a humidifier or inhale steam to ease congestion
- Avoid smoking and smoky environments
- Take paracetamol or ibuprofen for fever, aches, or discomfort
- Honey in warm drinks may help soothe the throat (not for children under 1)
Treatment from a GP
A GP may:
- Prescribe antibiotics only if bacterial infection is suspected (uncommon)
- Recommend inhalers or bronchodilators for wheezing or breathing difficulty
- Advise on cough management
- Provide fit notes for work or study
When Referral Is Needed
Referral to a respiratory specialist may be recommended if:
- Symptoms persist or worsen despite treatment
- Recurrent or chronic bronchitis is suspected
- There is significant shortness of breath or oxygen saturation issues
- Complications such as pneumonia are suspected
