Sticky, Oily, Or Greasy Stools

What Causes Oily Stools?

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.

Diagnose your symptoms now!
  • understand what's happening to your body
  • see your health summarized and in detail
  • have a doctor review your case (optional)

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:

  • 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 "oily stools" as a symptom.  Here are four possibilities:
  • Short Bowel Syndrome
  • Giardia
  • Liver Congestion
  • Inadequate Fiber Intake

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:
sickness caused by wine
high dairy product consumption
mild diesel exhaust exposure
slightly pale stools
giardia infection
edema of the ankles/lower legs
allergy to chemicals
offensive-smelling stool
significant abdominal distension
anal itching
undigested fat in stools
... 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 oily stools:
Cause Probability Status
Short Bowel Syndrome 99% Confirm
Inadequate Fiber Intake 25% Unlikely
Giardia 3% Ruled out
Liver Congestion 2% Ruled out
* This is a simple example to illustrate the process
