Autistic 4 year old drinks a lot … sign of diabetes?

My son drinks a lot ( juice, water, etc ) . He will finish his drink and would want another one. If there’s water in it he will take his time drinking it or drink it fast so he can get some juice. He runs constantly, full of energy and doesn’t take a nap in the day. I’m worried he might have diabetes due to him drinking and eating a lot. His breath smells weird to me but I think it might just be because I use the strawberry/banana oragel toothpaste that has a strong scent to it. I don't know I think I’m being paranoid.. any advice?
