What does yellow stool signify?

Yellow/Pale Brown/Grey: Bright yellow diarrhea can signify a condition known as Giardiasis (see sidebar). Stool that is yellow or pale can also result from reduced production of bile salts, since a normal, brown-coloured stool acquires its hue from breaking down bile.

What color is your stool if you have liver problems?

Considerations. The liver releases bile salts into the stool, giving it a normal brown color. You may have clay-colored stools if you have a liver infection that reduces bile production, or if the flow of bile out of the liver is blocked. Yellow skin (jaundice) often occurs with clay-colored stools.
