COPD bronchiectasis

What is bronchiectasis?
Bronchiectasis is a lung disease that occurs when the walls of the breathing tubes or airways widen due to chronic inflammation and/or infection. This results in irreversible damage to the lungs, which allows mucus to pool in the damaged airways. Infection in these breathing tubes contributes to ongoing inflammation in the airways. It may affect many areas of the lung, or it may appear in only one or two areas. Bronchiectasis is characterised by recurrent chest infections (flare-ups).
