There are several medical conditions that may cause yellow bowel movements. If bowel movements that are yellowish in color are seen, an examination by a physician may be required to rule out a serious medical issue. A doctor will complete a stool analysis to determine if yellow stools are a result of a digestive condition, or if bacterial, viral or parasitic infections are present.
