Thank you for the replies it has helped. We went into hospital as Scott was vomiting all day, empty stomach, then ketones 4+. They put him on drips, then in passing one of the nurses said "cant bring the sugars down too quick or he,l get edema on the brain! She then left! I was still reeling at this stage and just watched her walk away. Of course after that it just went round in my mind but everyone seemed too busy to ask. I like to know every thing I can about this condition, it helps me to cope but I do find that when I ask questions at clinic, I get brushed aside. I am so grateful I have found this site, it is a saviour for me! Thank you all so much.
