Causes of bronchiectasis in children
Bronchiectasis is caused by damage to your child’s lungs.
Some known causes include:
- severe infections such as pneumonia, tuberculosis or whooping cough -this is the most common known cause
- a problem with your child’s immune system - immune deficiency - which causes lots of bacterial infections
- a problem with the way your child’s lungs grew in the first place
- a blockage caused by something your child inhaled, such as a small nut
- an underlying inherited disease such as cystic fibrosis or primary ciliary dyskinesia
- accidentally breathing in stomach acid that has come up your child's food tube
It’s important to try and find out how their airways were damaged. This can help with treatment and preventing more damage. But for about 40% of children and adults, there is no clear cause for their bronchiectasis.
