Hello everyone. I am mum to a 16yr old girl who has been fainting for years. After loads of different tests (mainly heart) they are now looking at the possibility of diabetes. My daughter just ran home from school (uphill and about a mile) and was shaking and felt faint. She did the blood test for the very first time and it came up with E-4. We are TOTALLY naive about all this so can you tell us what that means please? She went out without eating a thing and the last time she ate was about 5pm yesterday which was pasta. She is very hyperactive and very slim (she wears 13yr old clothes) but when she eats, she eats tons. Thanks for reading this and any help/advice is most welcome since I cant get hold of our diabetic nurse at the moment. Alison
