Bronchiectasis (bron-kee-ek’-tas-is) is a chronic lung disease that can result from infections and swelling which injures the walls of the airways. The airways are the tubes that carry air in and out of your lungs.

Injury to the lung can cause problems with mucus buildup. The mucus creates a place in which germs can grow and lead to even more lung infections. Each infection causes more damage to the airways. Over time, the airways become stretched out, flabby, and scarred. When you breathe, it may be hard to move air in and out. This can affect how much oxygen reaches your other organs. If your lungs cannot move enough oxygen into your body, bronchiectasis can lead to serious illness, such as heart failure.

Bronchiectasis can affect just a part of one lung or many areas of both lungs. It often starts in childhood, but symptoms may not appear until months or even years, after you have started having frequent lung infections.

Types of Bronchiectasis

There are two types of bronchiectasis:

  • Acquired bronchiectasis: This type occurs in adults and older children. This type is more common.

  • Congenital bronchiectasis: This type you are born with and most often affects infants and children. About half of all cases result from a disease called cystic fibrosis


Symptoms vary widely from patient to patient. The symptoms may include:

  • Coughing (worse when lying down) and shortness of breath

  • Weakness, weight loss, fatigue

  • Tan or green, foul smelling or bloody mucus


Doctors test for this disease with a chest x-ray, breathing tests, sputum culture, and/or CT scan.


Patients are often given antibiotics for infection and medicines to open the airways. There are also airway clearance techniques or treatments to help clear lungs. Lung transplants may be an option for severe cases.


If lung infections are treated right away, bronchiectasis is less likely to occur. Patients should avoid cigarette smoke and other lung irritants, and not use sedatives.
