Bronchiectasis
Acquired bronchiectasis; Congenital bronchiectasis; Chronic lung disease - brochiectasis
Bronchiectasis is a disease in which the large airways in the lungs are damaged. This causes the airways to become wider.
Bronchiectasis can be present at birth or infancy or develop later in life.
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 . Breathing in food particles can also lead to this condition.

Exams and Tests
The health care provider will perform a physical exam. When listening to the chest with a stethoscope, the provider may hear small clicking, bubbling, wheezing, rattling, or other sounds, usually in the lower lungs.
Tests that may be done include:
- Aspergillosis precipitin test (to check for signs of an allergic reaction to fungus)

Lung function tests
to measure breathing and how well the lungs are functioning
Lung function tests
Pulmonary function tests are a group of tests that measure breathing and how well the lungs are functioning.
Treatment
Treatment is aimed at controlling infections and sputum, relieving airway blockage , and preventing the problem from becoming worse.
Airway blockage
Breathing difficulty may involve:Difficult breathingUncomfortable breathingFeeling like you are not getting enough air
Daily drainage to remove sputum is part of treatment. A respiratory therapist can show the person coughing exercises that will help.
Medicines are often prescribed. These include:
- Antibiotics to treat infections
- Bronchodilators to open up airways
- Expectorants to help loosen and cough up thick sputum
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 person has a lot of bleeding in the lungs.
Resect
Lung surgery is surgery done to repair or remove lung tissue. There are many common lung surgeries, including:Biopsy of an unknown growthLobectomy, ...
Outlook (Prognosis)
The outlook depends on the specific cause of the disease. With treatment, most people live without major disability.

When to Contact a Medical Professional
Call your provider if:
-
Chest pain
or shortness of breath gets worse
Chest pain
Chest pain is discomfort or pain that you feel anywhere along the front of your body between your neck and upper abdomen.
- 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.
Vaccines
Vaccines are used to boost your immune system and prevent serious, life-threatening diseases.
