To prevent bronchiectasis, it's important to prevent the lung infections and lung damage that can cause it.
Childhood vaccines for measles and whooping cough prevent infections related to these illnesses. These vaccines also reduce complications from these infections, such as bronchiectasis.
Avoiding toxic fumes, gases, smoke, and other harmful substances also can help protect your lungs.
Proper treatment of lung infections in children also may help preserve lung function and prevent lung damage that can lead to bronchiectasis.
Stay alert to keep children (and adults) from inhaling small objects (such as pieces of toys and food that might stick in a small airway). If you think you, your child, or someone else has inhaled a small object, seek prompt medical care.
In some cases, treating the underlying cause of bronchiectasis can slow or prevent its progression.
