Hello!

I've been recently diagnosed with polynurophaty by EMG study.
Apparently my blood work worked out normal, but I'm still digging and it looks like my A1C is 6.2 - in lab norms that the top of the norm, but from what I found that's being classified by Pre-diabetes.
My fasting glucose on the same lab work was 69.6 so I guess that's why anything to do with diabetes was discarded.
Should I re-do the test with drinking glucose and testing 2h after?
What can high A1C and low fasting glucose means?

I'm a bit overweight, but I don't eat trash. By any means I'll make significant dietary changes and try to loose as much weight as possible (not that easy when I can't run )

Any advise would be useful!
