Bronchitis is a respiratory disease where the mucus membrane in the bronchial passages becomes irritated and inflamed. Acute bronchitis is common and is usually caused by a viral infection. Irritated membranes swell and grow thicker causing bronchial passages to narrow. The tiny airways in the lungs begin to close resulting in coughing spells. Phlegm may be present and breathlessness is a common symptom.
After several days recovering from the initial infection, the bronchia begin to return to normal.
