Re: Surgery and blood sugar
If you are currently at the high end of normal, I suspect that with the stress you may go slightly over into the pre-diabetic range with your pre-op labs. At that point the odds are that they will do nothing other than warn you about it.
That's my best guess. Best of luck with the surgery. Hope all goes well.
