Hi yes i think asking to be refered would be a good idea, have you had a look on the DIABETES U.K website they have some very interesting info on there about type 1 and type 2 diabetes, i think there is a helpline phone number you could contact they maybe able to advise you of what to do, when it your child it can be very frustrating when no one seems to be bothered or tells you that theres nothing to worry about but a mother knows when there child is not right.
Let me know how you get on, i do hope you get the help and care you need for your son, keep in touch.
