What does explosive diarrhea look like?

Explosive diarrhea looks like sudden, forceful, watery, and often foul-smelling stools with a lot of gas, sometimes appearing cloudy or greasy, due to rapid bowel contractions forcing out liquid faster than the body can reabsorb it.

The timing varies greatly, but immediate reactions (within an hour) often point to intolerances or reflex issues, while longer delays (hours/days) usually signal infections.
