Frequent stools can have various causes, ranging in severity from 'troubling' to 'critical'. 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 frequent stools, we could:
regular unexplained vomiting
elevated ESR
moderate left iliac pain after meals
inner trembling
regular aspirin use
major unexplained weight loss
low lymphocyte count
chronic productive cough
irritated eyes
ovarian cysts
recent onset vomiting
resolved atypical recent headaches| Cause | Probability | Status |
|---|---|---|
| Crohn's Disease | 95% | Confirm |
| Ulcerative Colitis | 28% | Unlikely |
| Hyperthyroidism | 28% | Unlikely |
| Vitamin D Need | 4% | Ruled out |
| Gastritis | 1% | Ruled out |
| Lactose Intolerance | 1% | Ruled out |
| Food Allergies | 1% | Ruled out |
| HIV/AIDS | 0% | Ruled out |
