My 6 year old daughter has been put on a gluten-free Diet

[Esmesmommy]

Any advise would be great fully received... My daughter has struggled with stomach / bowel problems pretty much since the day she was born what started as colic turned to being unable to pass a stool as we introduced solid foods a number of different medications have been prescribed over the years nothing really resolving the issue. 3 months ago at another trip to the GP regarding this I asked for her to be tested for a Gluten Allergy. The GP told me to try removing gluten from her diet and gave us a blood test form please don’t think me stupid but I did as advised and the blood test has returned negative for an allergy however we have persisted with a gluten-free diet and the pains she normally experiences seem reduced I want the GP to look into this further and am not happy after 6 years with this outcome but keep being told just keep trying with the gluten-free diet and let’s see what happens. Has anybody else experienced this and should I keep pushing for a referral to paediatrics as my heart is telling me to do? 
thanks

As a mom, I would listen to your heart.  You know your child best.  Get a second or even third opinion.  Know that your child must be on gluten for about 8 to 12 weeks for the blood test and 2 to 4 weeks before intestinal biopsies otherwise the tests will be negative.
