What Causes Shortness Of Breath?
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:
- Research the topic
- Find a doctor with the time
- Use a diagnostic computer system.
The process is the same, whichever method is used.
Step 1: List all Possible Causes
We begin by identifying the disease conditions which have "shortness of breath" as a symptom. Here are seven possibilities:
- Vitamin B12 Need
- Mitral Valve Prolapse
- Congestive Heart Failure
Step 2: Build a Symptom Checklist
We then identify all possible symptoms and risk factors of each possible cause, and check the ones that apply:
edema of the feet
having a moderate fever
chronic productive cough
severe fatigue after slight exertion
very great unexplained weight loss
edema of the abdomen
broad-spectrum antibiotic use
rapid pulse rate
loss of appetite
severe muscle weakness
... and more than 50 others
Step 3: Rule Out or Confirm each Possible Cause
A differential diagnosis of your symptoms and risk factors finds the likely cause of shortness of breath:
|Mitral Valve Prolapse
|Congestive Heart Failure
|Vitamin B12 Need
* This is a simple example to illustrate the process
