Type 1 is not preventable, but detecting it is important as it could arise in infants (half of cases). Consequences are kind of hard if ignored / not detected. Then proper glucose monitoring can be set.
And more generally, detecting glucose level from urine is a bit late for any kind of diabetes. So pretty useless for Type 2 monitoring I think.
Meant to inquire about this with my other response. Do you have a source for this?
My daughter was diagnosed at 2 (almost 3) and doctors gave the impression this is younger than average. We're also in many Facebook T1D parent support groups. There are certainly some diagnosed under 2, but it seems to be quite rare (1% maybe).
That's all anecdotal though. I'm genuinely curious about formal stats.
Just that the paper/research in question has been conducted with adults in mind. Perhaps infants don't produce enough urine, I'm not sure.
