Overview
Bronchitis is an inflammation of the airways (bronchial tubes) that carry air to your lungs. It often follows a cold or flu and causes a cough with mucus. There are two main types: acute bronchitis, which lasts for a few weeks, and chronic bronchitis, which is a long-term condition that is part of COPD (Chronic Obstructive Pulmonary Disease).
Key facts
- Most cases of acute bronchitis are caused by viruses, not bacteria, so antibiotics usually do not help.
- Acute bronchitis typically goes away on its own within 1 to 3 weeks.
- Chronic bronchitis is a serious, long-term condition that requires ongoing medical care.
Yes, bronchitis is very common. Acute bronchitis is one of the most frequent respiratory illnesses, especially during cold and flu season.
Anyone can get bronchitis, but it is more common in children under 5, older adults, smokers, and people with weakened immune systems or long-term lung conditions.
Symptoms
- Trouble breathing or shortness of breath that is severe or gets worse
- Chest pain that is sharp or constant
- Coughing up blood (more than a few streaks)
- Fainting or feeling like you might pass out
- Bluish colour around the lips or fingertips
- ⚠High fever (above 38.5°C or 101.3°F) that does not come down with over-the-counter medicine
- ⚠Cough that lasts more than 3 weeks
- ⚠Wheezing that does not improve with rest or a simple inhaler (if you have one)
- ⚠Symptoms that get worse instead of better after a few days
Common symptoms
- A cough that brings up mucus (sputum) that may be clear, white, yellow, or green
- Wheezing or a whistling sound when breathing
- Shortness of breath, especially during activity
- Chest discomfort or a feeling of tightness
- Tiredness or fatigue
- Low-grade fever (usually less than 38°C or 100.4°F)
Symptoms in children
- The same symptoms as adults, but children may also have a runny or stuffy nose, sore throat, and vomiting from coughing
- Young children may have wheezing that sounds like asthma
- They may be more irritable or have trouble feeding
Symptoms in older adults
- Confusion or drowsiness due to low oxygen levels
- Rapid breathing or increased heart rate
- A bluish tint to the lips or fingernails, which is a medical emergency
Causes
Main causes
- Viral infections – the same viruses that cause the common cold or flu
- Bacterial infections – less common, but can happen especially if you have another lung condition
- Irritants – such as tobacco smoke, air pollution, dust, strong fumes, or chemical vapors
Risk factors
- Smoking or being around secondhand smoke
- A weakened immune system (due to illness, chronic conditions, or certain medicines)
- Frequent colds or flu
- Working in environments with dust or chemical fumes (like coal mines, grain elevators, or textile factories)
- Living in a crowded area or attending daycare
When to see a doctor
See a doctor urgently if:
- If you have trouble breathing, chest pain, cough up blood, or a high fever that doesn't go down
- If you feel confused or unusually sleepy
- If your lips or nails look blue
Book a routine appointment if:
- If your cough lasts more than 3 weeks
- If you have repeated episodes of bronchitis
- If you have wheezing that is new or getting worse
- If you have a chronic condition like asthma, heart disease, or COPD
- If you are over 65 or have a weak immune system
Diagnosis
Your doctor will ask about your symptoms, listen to your lungs with a stethoscope, and check your oxygen levels with a small sensor on your finger. Based on that, they may decide if more tests are needed.
Tests that may be done
- Chest X-ray – to rule out pneumonia or other lung problems
- Sputum culture – testing your mucus for bacteria
- Blood tests – to check for infection or low oxygen levels
- Pulse oximetry – a quick, painless test that measures oxygen in your blood
- Lung function tests (spirometry) – if chronic bronchitis is suspected
What to expect at your appointment
Most tests are quick and painless. Your doctor may ask you to cough or breathe deeply. You might have a small blood draw. Results often come back the same day or within a few days.
Treatment
Treatment for acute bronchitis focuses on easing symptoms while your body fights the infection. For chronic bronchitis, the goal is to manage symptoms and prevent flare-ups. Always follow your doctor's advice.
Self-care at home
- Get plenty of rest – your body needs energy to heal.
- Drink warm fluids like tea, soup, or water with honey to soothe your throat and thin mucus.
- Use a humidifier or breathe in steam from a bowl of warm water to help loosen cough.
- Avoid smoke, strong fumes, and other lung irritants.
- Try honey (for adults only, not for infants under 1 year) to calm a cough.
Medical treatments
Your doctor may suggest over-the-counter medicines to reduce fever or ease aches (always ask which ones are safe for you). Inhaled medicines called bronchodilators can help open up the airways and reduce wheezing, but they are only used if needed. Antibiotics are rarely prescribed unless your doctor suspects a bacterial infection. For chronic bronchitis, treatment may include regular inhalers, pulmonary rehabilitation (a supervised exercise and education program), or oxygen therapy if needed.
When is surgery considered?
Surgery is not used for acute bronchitis. For severe chronic bronchitis (emphysema-like type) that does not respond to other treatments, lung volume reduction surgery or a lung transplant may be considered in very rare cases. This is a complex decision made by a specialist team.
Living with this condition
If you have acute bronchitis, focus on rest and fluids. You may need to take time off work or school until you feel better. For chronic bronchitis, it helps to have a daily routine that includes taking your medicines as prescribed, staying active within your limits, and avoiding triggers like smoke or cold air.
Lifestyle tips
- Quit smoking if you smoke – this is the most important step.
- Avoid secondhand smoke and other lung irritants.
- Wash your hands often to reduce the risk of getting new infections.
- Get enough sleep to keep your immune system strong.
- Stay up to date with recommended vaccines (such as the flu and pneumonia vaccines).
Diet and exercise
Eat a balanced diet with plenty of fruits, vegetables, whole grains, and lean protein to support your immune system. Gentle exercise, such as walking or stretching, can help maintain lung function and energy levels. Avoid strenuous activity when you are short of breath. If you have chronic bronchitis, ask your doctor about a pulmonary rehabilitation program.
Mental health and emotional wellbeing
Having a persistent cough or chronic lung condition can be frustrating and may lead to anxiety or depression. It's normal to feel worried or down. Talk to your doctor about how you're feeling – they can offer support or refer you to a mental health professional.
Prevention
You cannot always prevent bronchitis, but you can lower your risk by avoiding infections and lung irritants. Good handwashing, staying away from sick people, and not smoking are key.
Vaccines
Getting a flu vaccine every year can help prevent the flu, which is a common cause of bronchitis. The pneumonia vaccine is also recommended for adults over 65 and for people with chronic health conditions – ask your doctor if it's right for you.
Screening programmes
There is no routine screening for bronchitis. However, if you have a chronic cough or are at high risk, your doctor may do lung function tests to check for chronic bronchitis or other lung conditions.
Complications
If left untreated
- Pneumonia – an infection that inflames the air sacs in the lungs
- Worsening of asthma or COPD – if you already have these conditions
- Respiratory failure – when your lungs cannot get enough oxygen into your blood (very rare with acute bronchitis)
Long-term outlook
For acute bronchitis, the outlook is excellent. Most people feel much better within a week and recover fully in 1 to 3 weeks. For chronic bronchitis, treatment can control symptoms and help you maintain a good quality of life. Working closely with your healthcare team and making healthy changes can make a big difference.
