Constrictive Bronchiolitis
A small-airway lung disease that can cause shortness of breath and exercise intolerance, sometimes associated with deployment-related airborne exposures.
Lungs & Respiratory- What exactly is constrictive bronchiolitis?MedlinePlusMay 2026
Constrictive bronchiolitis is a condition where the small airways in your lungs become inflamed and scarred, causing them to narrow and tighten. This makes it harder for air to flow through your lungs when you breathe.
- How does it affect my breathing?MedlinePlusMay 2026
When your small airways narrow, less air can get in and out of your lungs, so you may feel short of breath, especially when you're active. You might also have a cough and feel like you can't get enough oxygen.
- Is this condition similar to asthma or chronic bronchitis?MedlinePlusMay 2026
It's similar to both conditions but different—like asthma, it involves airway narrowing, but constrictive bronchiolitis causes permanent scarring rather than reversible tightening. Unlike chronic bronchitis, it affects the smallest airways rather than the larger tubes.

Constrictive bronchiolitis usually doesn't go away completely because the scarring is permanent, but treatment can help manage symptoms and slow down any worsening. Some people stay stable for years with proper care.
