Bronchiectasis is a lung condition in which the airways of the lungs get bigger and often get infected. It occurs mainly in people who have diseases that affect different parts of the body, such as cystic fibrosis, although it may occur after a severe infection, such as pneumonia.

Symptoms of bronchiectasis differ from person to person. A common symptom is a cough that brings up mucus (sputum).

Bronchiectasis is treated by avoiding things that can irritate your lungs and by using techniques and medicines to help clear mucus out of your lungs. You may need antibiotics.
