What is bronchomalacia?

Bronchomalacia is a condition where the cartilage in the bronchi is weak. Your bronchi are flexible but firm airways in your lungs. Normally, c-shaped cartilage structures surround your bronchi like protective shells. These firm structures allow your bronchi to open as your lungs expand and contract. Without their support, your bronchi become narrow, especially during exhalation (when you breathe out).
