Bronchitis is when the tubes that carry air to your lungs (called bronchial tubes) become swollen and produce extra mucus. This causes coughing, often with phlegm (thick mucus), and makes it harder to breathe. There are two main types: acute bronchitis, which usually gets better on its own, and chronic bronchitis, which is a long-term condition that needs ongoing care.
Key facts
Yes, bronchitis is very common. Most people have acute bronchitis at least once in their life. Chronic bronchitis affects millions worldwide, especially older adults and smokers.
Anyone can get acute bronchitis, but it is more common in children under 5 and during winter months. Chronic bronchitis mainly affects adults over 40 who smoke or have a history of smoking, as well as people exposed to lung irritants like dust or chemical fumes.
Your doctor will start by asking about your symptoms, medical history, and whether you smoke. They will listen to your lungs with a stethoscope to check for wheezing or crackling sounds. Based on that, they may recommend tests to confirm the diagnosis or rule out other conditions.
Treatment depends on whether you have acute or chronic bronchitis. Acute bronchitis usually gets better on its own with rest, fluids, and time. Chronic bronchitis is managed with lifestyle changes and treatments to help you breathe easier and prevent flare-ups.
Living with chronic bronchitis means taking care of your lungs every day. Avoid triggers like smoke, pollution, and strong smells. Keep up with your medications and breathing techniques. Stay active as much as you can, and rest when you need to.
Eat a balanced diet with plenty of fruits, vegetables, and whole grains to support your immune system. Gentle exercise, like walking or light stretching, can help keep your lungs strong. If you feel breathless, try breathing exercises like pursed-lip breathing. Talk to your doctor before starting a new exercise programme.
Acute bronchitis cannot always be prevented, but you can lower your risk by washing hands, avoiding sick people, and not smoking. For chronic bronchitis, preventing it starts with quitting smoking and avoiding lung irritants. Getting vaccinated against the flu and pneumonia also helps.
The annual flu vaccine is recommended for everyone, especially people with chronic lung conditions. The pneumonia vaccine (pneumococcal vaccine) is also advised for adults over 65 and those with health conditions – check with your doctor.
There is no routine screening for bronchitis. However, if you have a chronic cough or are at high risk (e.g., long-term smoker), your doctor may suggest lung function tests to catch problems early.
For acute bronchitis, most people recover fully within a few weeks with home care. Chronic bronchitis is a long-term condition, but with proper treatment and lifestyle changes, many people manage their symptoms well and maintain a good quality of life. Staying active, quitting smoking, and following your doctor's plan can make a big difference.

Most tests are quick and painless. For sputum culture, you will be asked to cough up phlegm into a cup. Blood tests involve a needle prick. Pulmonary function tests require you to blow into a tube several times. Your doctor will explain each test and what the results mean. Usually, you get results within a few days.
Your doctor may suggest over-the-counter remedies to relieve fever, pain, or cough. For bacterial infections, they may prescribe antibiotics – but antibiotics do not work for viral bronchitis. For chronic bronchitis, doctors often recommend inhaled bronchodilators to open airways, and sometimes pulmonary rehabilitation (a programme of exercise and education). Always follow your doctor's advice; do not take any prescription medication without their guidance.
Surgery is very rarely needed for bronchitis. In severe chronic bronchitis, a lung volume reduction procedure may be considered, but this is only for a small number of people and requires specialist review.
Living with a long-term lung condition can be stressful and may cause anxiety or depression. It is common to feel frustrated or worried. If you notice mood changes, talk to your doctor or a mental health professional. You are not alone.
