In this article, we will discuss various Causes of Bronchiectasis. So, let’s get started.
Any obstruction in the airway such as aspiration of foreign particles, tumor mass, compression due to adjacent lymphadenopathy, stenotic airway, congenital underdevelopment of the airway or bronchial atresia.
Infection (bacterial, nontuberculous mycobacteria, etc)
Immunodeficiency (hypogammaglobinemia, HIV infection, bronchiolitis obliterans post lung transplantation)
Genetic causes (cystic fibrosis, Kartagener’s syndrome, alpha-1 antitrypsin deficiency)
Auto-immune or rheumatologic causes such as Sjogren syndrome, rheumatoid arthritis, inflammatory bowel disease
Immune-mediated disease such as allergic bronchopulmonary aspergillosis
Post radiation fibrosis or idiopathic pulmonary fibrosis (causes traction bronchiectasis)
