Duration Of Current Diarrhea Symptom

What Causes Chronic Diarrhea?

Chronic diarrhea can have various causes, ranging in severity from 'minor' to 'very serious'.  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 chronic diarrhea, 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 "chronic diarrhea" as a symptom.  Here are eight of many possibilities (more below):
  • Blastocystosis
  • Anxiety
  • Bacterial Dysbiosis
  • Epstein-Barr Virus
  • Lactose Intolerance
  • Malaria
  • Hyperthyroidism
  • Stress

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:
depression with fatigue
hot flashes between period
high systolic blood pressure
recent oily hair
frequent severe earaches
red palms/fingertips
weak appetite
severe vision disturbances
paying great attention to detail
low TSH
very frequent stools
weak sexual desire
... and more than 120 others

Step 3: Rule Out or Confirm each Possible Cause

A differential diagnosis of your symptoms and risk factors finds the likely cause of chronic diarrhea:
Cause Probability Status
Stress 99% Confirm
Blastocystosis 18% Unlikely
Hyperthyroidism 20% Unlikely
Epstein-Barr Virus 5% Ruled out
Malaria 0% Ruled out
Lactose Intolerance 0% Ruled out
Bacterial Dysbiosis 0% Ruled out
Anxiety 0% Ruled out
* This is a simple example to illustrate the process

Arriving at a Correct Diagnosis

The Analyst™ is our online diagnosis tool that learns all about you through a straightforward process of multi-level questioning, providing diagnosis at the end.

If you indicate irregular stools, The Analyst™ will ask further questions including this one:
If you suffer significantly from diarrhea (at least once per week), for how long has this been a problem?
Possible responses:
→ It is not a problem / don't know
→ It started within the last week
→ It started within the last month
→ I've had it for 1 to 3 months
→ I've had it for over 3 months
Based on your response to this question, which may indicate no significant diarrhea, recent onset diarrhea, diarrhea for 1-3 months or chronic diarrhea, The Analyst™ will consider possibilities such as:
IBS (Irritable Bowel Syndrome)
Most people with IBS have intermittent bouts of diarrhea.
Stress and anxiety are common causes of rapid food transit through the intestines.
Vitamin B12 Requirement
Intermittent diarrhea can be a sign of B12 deficiency.
