We haven been referred under paediatric care for 18 months and have been referred again to a top gastro paediatrician, and all they keep doing is prescribing different medicines to make her go to the toilet. She has been off dairy as they think she may have an intolerance for over a year, this is made no difference. I have been told about a non invasive intolerance test which uses frequencies to test all food groups to determine what her intolerances are, has anyone had this done it and it be effective? We have tried excluding all food groups and it has made no difference, her paediatrician thinks she may be intolerant to a few things but won't do any sort of test to see what it is. Any advice?
