The cause of bronchiectasis is often not clear. Some conditions that affect or damage airways can cause the disease, for example:
The main symptom of bronchiectasis is a cough which produces a lot of sputum, tiredness and poor concentration as well as wheeziness. A lung scan and other lung and sputum tests help to confirm the diagnosis. Treatment includes regular physiotherapy, which helps coughing up and clearing the mucus, and courses of antibiotics. Surgery is occasionally needed.
Bronchiectasis is an abnormal widening of one or more airways. Normally, tiny glands in the lining of the airways make a small amount of mucus. Mucus keeps the airways moist and traps any dust and dirt in the inhaled air. Because bronchiectasis creates an abnormal widening of the airways, extra mucus tends to form and pool in parts of the widened airways. Widened airways with extra mucus are prone to infection.
