Rarely, it may be congenital. Bronchiectasis is caused by recurrent inflammation or infection of the airways and primarily affects children, although any age may be affected. It may be present at birth, but most often begins in childhood as a complication from infection or foreign body aspiration . Cystic fibrosis , lung infections, and bronchial tumors are some predisposing factors. Symptoms may develop gradually after an infection, and become progressively worse.
Symptoms vary widely with the individual.
The incidence is 1 in 10,000 people. This disease may also alter the results of a chest MRI . Treatment is aimed at controlling infections, secretions, airway obstruction , and complications. Regular, daily postural drainage to remove bronchial secretions is a routine part of treatment. A respiratory therapist can teach postural drainage and effective coughing exercises to affected people and their families.
