Blood sugar 1,022

I don't know much about juvenile diabetes but my friends 3 year old daughter just got diagnosed and her blood sugars were 1,022.    My friend put on Instagram that she has a terminal illness., I can't believe this she was normal a week ago and now she is at the Children's hospital fighting this and phnemoina.  I guess my question is, what does this mean?  My heart breaks for this family. 😢
