Loose Stool

Exudative diarrhea often occurs due to an infection or inflammatory bowel disease, such as Crohn's disease, and causes there to be blood and pus in the stool.

Osmotic diarrhea occurs when the body is unable to absorb a nutrient, such as lactose or fructose, and it draws excess water into the bowels, like a sponge, resulting in loose stool.
