My son was diagnosed with type 1 when he was 10. (he's now 15.) All of the symptoms listed on another post are accurate and the other thing is that once you do have diabetes, you'll know rather quickly as what typically happens is the child will 'hit a wall' and their bodies will completely shut down to where you take them in to the ER and low and behold, they tell you your child has diabetes and your child will have to typically spend a week or so in the hospital and start taking insulin every day to manage your blood sugars. This didn't happen to us. Luckily we discovered it early, while on vacation in Hawaii, when my son started having extreme thirst, lethargy (when eating carbs/sugars) and even wet the bed for two nights in a row (never did that before). Even though we have no history and diabetes in the family and he is a skinny little active kid, my gut told me it was diabetes. (it's crazy how our 'mom insticncts' work!) it's an easy test to determine. All they need to do is test your blood sugar with a slight prick to the finger (which my son now does 4-5 times a day). If the blood sugar is anything over 120, you look in to it further with a doctor. For a normal person, our bodies are constantly regulating our blood sugars to manage between 80-120. For a type 1 diabetic, their bodies are, in essence, turning on themselves (diabetes is an autoimmune disease) and destroying the beta cells in the pancreas so their bodies can't correctly regulate their carb intakes. Based on your short post, it sounds more like your son could have 'low blood sugar' issues or something like that. Not diabetes. But obviously it's best to just take the quick blood sugar test if there's any questions. I've also known of doctors denying the test to parents because they don't think the symptoms they are hearing are diabetes so they think the parent is over reacting. (I know two personal friends who had this experience and even when I first thought my son was showing signs of diabetes, the doctor in Hawaii didn't but tested my son anyways. He was 'surprised' to see his blood sugar numbers were 500+ and instantly sent us to the hospital.) so anyways, if your 'gut' is telling you something, go with it and demand testing. Good luck!
