Bronchiectasis is a little-known condition of the lungs. It occurs when the lungs’ airways become stretched and enlarged due to long-term mucus blockage. If the lungs are not able to properly clear out mucus, it will buildup overtime, potentially causing infection.
The infection and buildup of mucus together cause the inflammation that can weaken and stretch out the airways. Then, it can become a perpetual cycle with the stretched airways leading to further infection and the infection leading to further stretching of the airways.
