Typically "diabetic" means elevated blood sugars.

But before this happens in Type II... there is insulin resistance, and quite a bit of lows... the low blood sugars also starve nerves.

So the more informed doctors will say that pre-diabetes, or what is called impaired glucose tolerance... can be a factor.

Watching sugar and fructose intake is very important then in the diet. Smaller more frequent meals, better protein intake, and good fats, will help to keep blood sugars in the middle zone and hence help your nerves.

Supplements for PNers:
B12 and Vit D testing... fix those first.
Benfotiamine, and acetyl carnitine have studies showing improvements. Alpha lipoic acid or the new r-lipoic acid have a long track record in studies to help also.

New members here are encouraged to read our subforum with all the information to help themselves as well.
