Chronic diarrhea can have various causes, ranging in severity from 'minor' 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 chronic diarrhea, we could:
|Gallbladder Disease||2%||Ruled out|
|Vitamin B12 Need||0%||Ruled out|
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
Most people with IBS have intermittent bouts of diarrhea.
Rapid passage (or transit) of stool is one of the most common causes of diarrhea. Stool that leaves the large intestine too quickly is watery: there is not enough time for fluid and nutrients to be absorbed from the contents of the gastrointestinal tract.
Rapid Intestinal Transit also suggests the following possibilities:
Stress and anxiety are common causes of rapid food transit through the intestines.
Intermittent diarrhea can be a sign of B12 deficiency.
