My doc just told me today that my last fasting glucose test was low (this was done over two months ago). Does low glucose cause sfn? I was eating very healthy at The time, very low carbs ( only what I got from a small handful of berries in the morning, and whatever was in my veggies at lunch and dinner). No other sugar, no gluten, only organic foods nothing that came out of a bag, box or can except a bit of tuna and some beans. Would this have impacted my reading? Does this mean I need carbs?

He ordered another glucose fasting test but I have been eating poorly for the last two weeks. Carbs and sugar too.

I am not sure what this means, please help
