What could cause white stuff in stool?

Hmm: Pale or light colored stool can be related to lack of bile salts. I do not know what the cause is of bits of white material in the stool (if that is how it appears)l. If stool is predominantly white or light than possible causes include hepatitis, cirrhosis, or obstruction of a bile duct (i.e., gallstone or a mass). Any significant change in bowel habitus warrants assessment.
