Oily stools can have various causes, ranging in severity from 'minor' to 'needs attention'. 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 oily stools, we could:
diminished perspiration
mild abdominal discomfort
strong-smelling urine
significant diesel exhaust exposure
high dairy product consumption
cysts in breasts
recent onset nausea
itchy skin
diarrhea for 1-3 months
very pale stools
slightly pale stools
excessive flatulence| Cause | Probability | Status |
|---|---|---|
| Giardia | 92% | Confirm |
| Inadequate Fiber Intake | 23% | Unlikely |
| Liver Congestion | 5% | Ruled out |
| Short Bowel Syndrome | 3% | Ruled out |
