Bronchiectasis is a condition in which damage to the airways causes them to widen and become flabby and scarred. Bronchiectasis usually is the result of an infection or other condition that injures the walls of your airways or prevents the airways from clearing mucus. Mucus is a slimy substance that the airways produce to help remove inhaled dust, bacteria, and other small particles. When mucus can’t be cleared, it builds up and creates an environment in which bacteria can grow. This leads to repeated, serious lung infections which cause further damage to your airways, eventually preventing enough oxygen from reaching your vital organs. Bronchiectasis can lead to serious health problems, such as respiratory failure, atelectasis and heart failure.
