Bronchitis is an infection of the main airways of the lungs (bronchi), causing them to become irritated and inflamed.
The main airways branch off on either side of your windpipe (trachea).
They lead to smaller and smaller airways inside your lungs called bronchioles.
The walls of the main airways produce mucus to trap dust and other particles that could otherwise cause irritation.
Most cases of bronchitis happen when an infection irritates and inflames the airways, causing them to produce more mucus than usual.
The main symptoms of chest infections are a headache, temperature, aching muscles, tiredness and a chesty cough. These symptoms can be unpleasant but it usually gets better by 7 to 10 days.
