Definition of Bronchiectasis:

Bronchiectasis is destruction and widening of the large airways.

• If the condition is present at birth, it is called congenital bronchiectasis.
• If it develops later in life, it is called acquired bronchiectasis.

Causes, incidence, and risk factors:

Bronchiectasis is often caused by recurrent inflammation or infection of the airways. It most often begins in childhood as a complication from infection or inhaling a foreign object.

Cystic fibrosis causes about half of all bronchiectasis in the United States. Recurrent, severe lung infections (pneumonia, tuberculosis, fungal infections), abnormal lung defenses, and obstruction of the airway by a foreign body or tumor are some of the risk factors.

The condition can also be caused by routinely breathing in food particles while eating.
