Diabetes/pre diabetic questions for those who know about it!

I’m just curious if 105 after sleeping all night is pre diabetic?

After eating like 30 mins 160?

After I ate I felt weird also and my sugar went from 105 at 6 am to 160 in 15 mins.

If this isn’t the place just delete. I’m just trying to find someone who may know about it. I’m writing everything down for my appt but still curious.
