I wasn't sure if I should post this in here or in children's health, but here goes. This may be nothing to be concerned about, but my 8yo has been quite thirsty lately, drinking quite a bit more than usual. He has also been urinating a lot more frequently, getting up at night a few times. His appetite has been a bit off the last few months - nothing drastic, but just "off" - which I know is hard to explain. He's not having any specific UTI symptoms (such as lower abdominal discomfort or pain/burning on weeing). This has been going on for awhile now,possibly a couple months if it goes back to when his appetite changed a little. He's not lost any weight that I can see (weighing him is a struggle - he's autistic and doesn't stand still on the scale).
Anyway, we have a massive family history of diabetes in my family, including a number that are insulin dependent. I made a routine appointment with the GP but it's not until the 29th (soonest they could get him in for routine appointment). Should I be taking him in sooner, or using the next 2 weeks to note any possible things that might be related and jot them down, watching what he eats, just in case? Is this even a concern? I don't want to ignore something important, but neither do I want to be alarmed over nothing.
He will NOT cooperate for a blood test, so I anticipate an almighty shrieking session and the need for him to be held to get that done. I was hoping desperately that it could be checked by finger stick, but is that ridiculously naive?
