Hi--are you available to chat and did your child have any evaluation for this? It sounds on the surface like IBS (irritable bowel syndrome)
Very young children can get it but it is a diagnosis of exclusion, which means other problems have been ruled out
So, some of the disorders to be eliminated from consideration is celiac (wheat/gluten intolerance), inflammatory bowel disease (ulcerative colitis or Crohn's). Do any of these run in the family?
The site has shifted to another format and now will not let me answer. I suggest that you suggest a pediatric gastroenterologist (GI doc) examine the child
I want to help even if I cannot interact, so I looked up a site for you to examine and then I will opt out: http://digestive.niddk.nih.gov/ddiseases/pubs/ibschildren/#8
Thank you for caring and for asking
The child is my great grandchild and not in my care but the issue has
not been addessed except as constipation and the use of suppositories
