My 3 year old son is having diarrhea (3-4 times daily) with blood containing mucus. The blood is always at the end of the bowel movement. About 4 months ago my son had this same problem, we eliminated dairy products and most juices (apple & orange) from his diet. The problem then went away in a short time (week or so). Both times my son's pediatrician has tested a stool sample for bacteria, both times the test have come back negative. The bowel movements are usually preceded by abdominal cramping. Other than cramping there are no other symptoms. He eats well, very active, no fever, growing well, etc. We have an appointment on the 10th to see a pediatric specialist. Is this IBS, allergic colitis, or ulcerative colitis? Several member's (sister & aunt) of my wife's family have been diagnosed with IBS, is IBS hereditary? Thanks.

Blood is often a symptom that it is something other than IBS. Although the diarrhea from IBS sometimes makes hemaroids or anal fissures or other anal irritations bleed.IBS seems to be PARTLY hereditary. Heredity is not the only factor based on twin studies. In identical twins if one has IBS the other is more likely than a random sibling would. BUT there are plenty of mixed sets of identical twins so heredity cannot be the only factor involved. Environmental factors also play a role.Pretty much like high blood pressure, heart disease, cancer, and many other chronic diseases. Your genes may make you more, or less likely to get the problem, but whether you get it or not depends on the environment your genes end up in.K.
