The easiest way to identify a stomachache or bowel problem is through the child's vomiting or stools. If a child's bathroom habits change, take note. The child is obviously straining to have a bowel movement. Bowel movements have blood or pus. Bowel movement are watery.
Bowel movements are more frequent than usual for the child.
Children with the last two symptoms have diarrhea. Children with diarrhea have frequent bowel movements, and their bowel movements, or stool, are so watery that they conform to the shape of the diapers. Diarrhea should always be taken seriously because it takes away fluid from the body and, if not treated, can cause dehydration. Diarrhea can result in hospitalization or even death in only a few days if it is not treated. Fluids help lubricate the digestive system and are essential to almost all bodily functions.
