Dr. Zhou Xiaofeng
The main causes of bronchiectasis in children include the following aspects:
1. Congenital factors: Less common, possibly related to defects in bronchial cartilage development or developmental deficiencies in tracheal and bronchial muscles and elastic fibers. This type is more commonly seen in older children.
2. Acquired factors:
- Infections: The most common cause. Conditions such as measles, whooping cough, bronchiolitis, and severe pneumonia may lead to secondary bronchiectasis.
- Immune deficiencies: Including humoral immune deficiencies such as X-linked hypogammaglobulinemia and common variable immunodeficiency, as well as local immune defense deficiencies such as ciliary dyskinesia, which can all potentially cause bronchiectasis.
- Foreign body obstruction: Long-term presence of a foreign body in the airway may cause chronic obstruction and inflammation, leading secondarily to bronchiectasis.
If concerns arise, timely consultation with a qualified physician for evaluation and diagnosis is recommended.
