My three year old has had diarrhea for almost a month but without any other symptoms or change in diet. Is this something to be concerned about? Tks

CHRONIC DIARRHEA.... Most of the diarrhea are viral origin, no blood in stool, not much cramp or fever, resolves by an week or so. If longer, your child need to have an exam, test to find out the cause. Check with the child's pediatrician. By the time, give her pedialyte for each diarrhea, some yogurt, bananna, rice, applesauce, toast, etc.
