The hospital says that he has a severe lactose intolerance - with the source being his mother. She is eradicating all milk from her diet - but the little boy is still in the same situation. Very worrying! I wonder if it could be Gluten intolerance too. But have any of you heard of this happening? My friend is gluten and lactose intolerent - but not a full blown coeliac; it just affects her sinuses.
