6 Known Causes of Bronchiectasis

Bronchiectasis is the clinical term for the irreversible, progressive dilation, expansion, inflammation and scarring of the bronchi (tubes conducting air to the lungs), which eventually leads to airway obstruction, impaired mucociliary clearance and harbors microbes, causing further damage.

This rare condition often occurs secondary to another medical condition (e.g.,: cystic fibrosis, sinopulmonary disorders, respiratory tract infections, allergens, etc.) resulting in distortion and damage to one or more of the conducting airways. It’s important to acknowledge the two separately to correctly diagnose and treat both.

According to the British Lung Foundation, in 25 to 50 percent of cases, it’s not possible to know the cause of the bronchiectasis (these cases are called idiopathic bronchiectasis).

However, there are six known causes of the disease:

    I know not a lot of Dr’s and the medical profession talk or speak about something that happened in the 40s and early 50s Dr’s have always dismissed any conversation about it it’s a disease called PINKS DISEASE when I researched this I had it when I was 1 year old it was caused by MERCURY poisoning Mercury Was in teething powders and not 100% sure in the national dried milk my bronchiectasis could of come from that or pneumonia TB measles but the support site for PINKS information seems more relevant to all my health problems maybe each bronchiectasis patient over 50 or 60 should be asked about this one
