Sounds like your endo is on it, buddlemama. Let us know the results. If he is diagnosed, send me a PM and I'll give you the name of a website with lots of diabetics including parents.
i took him last tues to the endo and they sent him for an a1c, gad65, an insuin antibody, a pancreatic antibody, and IA 2 and a basic metoblize panel will let you know what results are they havent come back yet
I agree with Firefae. Those numbers are in the diabetic range and he is showing symptoms. Take him in and get an A1C done (an average of blood sugars for a couple months) to see if he is diabetic. If his numbers rise and he is not treated, he could start to show symptoms of DKA which are similar to a flu and vomiting and that is a medical emergency.
have him tested IMMEDIATLY
