what could this be?

My son age 12 has been ill for 3 months off and on of vomits and then diarrhea and severe pains in lower ab area he wakes up the pain is so strong.  He eats he vomits withing 2 hours he is tired and cranky missed now 2 weeks of school.  He has had 6 viles of blood drawn over last 7 days all normal but still his pain is keeping him so sick he has no strength.  He has had a colonoscopy and a biopsy of red tissue will be known this week.  Hours after colonoscopy he still has swollen stomach.  We know its not celiac, chron's, autoimmune and GI doctor today said treat it as IBS and gave no pain meds ......any help is appreciated

My Drs kept telling me it was nothing to do with what I was eating because all the conventional tests are coming back negative.  So if all your conventional tests come back negative that is good as there isnt anything seriously wrong that they can find.  But it is frustrating at the same time for sure.  Be proactice in your son's health and even if your Drs say stool tests are bogus and outdated request one to be sure or check out Enterolab.

Even if your celiac tests come back negative it doesnt mean he doesnt have an intolerance to gluten (as was the case with me). Cut out dairy and gluten for a week and see if that helps.  Go with a bland diet of rice, grilled chicken or white fish(no marinades) and well cooked green beans for dinners.  For breakfast try some hard boiled eggs, and turkey bacon (no pork).  Bananas are good, as is apple sauce.  No sodas or juices.  Try some pedialyte if you feel he is getting dehydrated.  You can also try some gluten free pasta but a lot of that has corn in it, and there might be an intolerance to corn, soy, wheat, dairy, nuts etc.

I had tests done through Enterolab which tests your stools for antibodies produces by gluten, dairy, soy, corn, nuts, etc.  Might be worth looking into IMO.
