<<Disclaimer: Verify this information before applying it to your situation.>> My son now 33 mths had a gut permeability test for he gets crapping etc when eating certain foods. The test shows that his ratio of lactulose to mannitol is high indicative of a leaking gut. What does this all mean? And are there any remedies? He has some intolerance to wheat and dairy products and some problems when eating meat as well. Thanks Angela Mum to Rainer 33mth DS
