Bronchiectasis

Definition

Bronchiectasis is a disease in which the large airways in the lungs are damaged. As a result of this damage, the airways become wider.

Alternative Names

Acquired bronchiectasis; Congenital bronchiectasis

Causes

Bronchiectasis is often caused by inflammation or infection of the airways that keeps coming back. Sometimes it begins in childhood after having a severe lung infection or inhaling a foreign object.

Cystic fibrosis causes about a third of all bronchiectasis cases in the United States. Certain genetic conditions can also cause bronchiectasis. These conditions include primary ciliary dyskinesia and immunodeficiency syndromes.

The condition can also occur when people often breathe in food particles while eating.

Symptoms

Symptoms develop over time. They may occur months or years after the event that causes the bronchiectasis.

Symptoms may include:

Exams and Tests

When listening to the chest with a stethoscope, the doctor may hear small clicking, bubbling, wheezing, rattling, or other sounds, usually in the lower lungs.

Tests may include:

Treatment

Treatment is aimed at controlling infections and sputum, relieving airway obstruction, and preventing complications.

Daily drainage to remove sputum is part of treatment. A respiratory therapist can show the patient coughing exercises that will help.

Medicines are often prescribed. These include antibiotics, bronchodilators, and expectorants.

Surgery to remove (resect) the lung may be needed if medicine does not work and the disease is in a small area, or if the patient has a lot of bleeding in the lungs.

Outlook (Prognosis)

The outlook depends on the specific cause of the disease. With treatment, most people live without major disability.

Possible Complications

When to Contact a Medical Professional

Call your doctor if:

Prevention

You can reduce your risk by promptly treating lung infections.

Childhood vaccines and a yearly flu vaccine help reduce the chance of some infections. Avoiding upper respiratory infections, smoking, and pollution may also reduce your risk of getting this infection.
