Well, yellow stool, if it happens again, can either be because of bile
or pancreatic enzymes. Bile
is released from the liver thru the gallbladder and bile
ducts, and checking billirubin levels determines if too little or too much bile is being released. Also if the bile is going thru digestive tract too fast or too slow on account of either constipation or diarrhea, it can change color of stool. Pancreatic enzymes, if not enough are getting into the digestive tract, can cause yellow stool.
