Runner’s diarrhea may occur during or after a long distance run, workout, occasional run, or walk (1) .

Exact cause of runner’s diarrhea is not known, but the following may contribute to it:

• Up and down moving of intestine
• Blood moving from the gut to the legs, what switches the gut to the rest mode so existing bowel content can’t be digested properly
• Stress, which may trigger irritable bowel syndrome
• Dehydration

Definition of Acute Diarrhea

Diarrhea means having over three loose bowel movements a day.

Acute (Latin acutus = sharp, pointed) diarrhea, by definition, lasts less than 3 weeks (1).

Causes of Acute Diarrhea

A) Acute INFECTIOUS Diarrhea

• Bacterial diarrhea usually occurs in food poisoning due to infection with bacteria like E. coli or salmonella.
• Parasitic diarrhea may be due to intestinal worms, or one-cell parasites like Entamoeba hystolytica, or giardia.
• Viral diarrhea mainly affects small children in kinder-gartens due to stool-to-mouth infection from other children, or (in poor countries) due to infection by water, contaminated by rotavirus.
