Why are people with dmd at a greater risk of repeated lower respiratory tract infections?

People with DMD have greater risk of lower respiratory tract infections because their clinical conditions become progressively worse due to progressive loss of respiratory muscular strength.

Explanation:

Duchene muscular dystrophy is a genetic condition that affects the muscle by causing progressive muscle degeration and weakness. This is cause when dystropin a protein that keep the muscle in good position is altered. People with DMD often have lower tract respiratory infection due to deterioration of muscular strength.
