What causes bronchiectasis?

Consequently, if the bronchi are damaged, secretions that are normally produced in the lung are not well removed and cause an increased likelihood that infections (pneumonia, bronchitis) can develop. Unfortunately these infections can cause further damage to the bronchial walls producing a cycle of increased damaged and then increased infection.
