Difficulty breathing out can have various causes, just like most other symptoms. Finding the true cause means ruling out or confirming each possibility – in other words, diagnosis.
Diagnosis is usually a complex process due to the sheer number of possible causes and related symptoms. In order to diagnose difficulty breathing out, we could:
Does it take significantly longer, or more effort, for you to breathe out than to breathe in?
Possible responses:→ Don't know
→ No, breathing out is just as easy as breathing in
→ I sometimes have more difficulty breathing out
→ I usually have more difficulty breathing out
COPD causes the lungs to undergo permanent changes that affect one's ability to exhale properly. These changes usually worsen over time.
