Shortness of breath can have various causes, ranging in severity from 'needs attention' to 'generally fatal'. 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 shortness of breath, we could:
|Vitamin B12 Need||24%||Unlikely|
|Congestive Heart Failure||3%||Ruled out|
|Mitral Valve Prolapse||0%||Ruled out|
|Chronic Bronchitis||0%||Ruled out|
How easily do you become short of breath?
Possible responses:→ Never / don't know
→ Only with great exertion, for example running fast
→ With moderate exertion such as jogging
→ Even with mild activity, such as walking
→ Very easily - even when I am not active
The main symptom of Pulmonary Fibrosis is shortness of breath, with or without exertion, made worse by even slight exertion.
