John A. Chabot, Endocrinology, Diabetes & Metabolism, answered on behalf of Columbia University Department of SurgeryDiarrhea results when the nutrients in food are not absorbed properly. When this occurs, stool can become loose, watery, oily and foul-smelling. Pancreatic enzymes are responsible for digesting fatty foods. If a tumor blocks the pancreatic duct, insufficient pancreatic juices in the intestines can lead to poor absorption and diarrhea, as the undigested food passes quickly through the digestive tract. If this happens, stool may float due to the higher fat content, appear bulky, greasy, and unusually pale.
