Hi
@SaraWalker7392
Is your daughter treated by insulin pump or through injections? And how old is she?
Through teenage years, particularly puberty, I know from personal experience it can be very hard to control BG readings.
I wouldn't worry as such. Worrying can increase BG readings which won't really help her, or yourself.
I agree with
@AndyS, check for ketones because they could be the cause.
What have you tried to reduce her BGs too? More information would be useful to suggest different ways to treat this.
I have been diabetic for 10 years and I'm now 17.
Always here to talk to if you need more advice.
