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.

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

      • Chest pain or shortness of breath gets worse
      • There is a change in the color or amount of phlegm you cough up, or if it is bloody
      • Other symptoms get worse or do not improve with treatment
  • 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.
