The other night I had a hypo and passed out with it , my blood sugar went below zero and it came up LO on my monitor. I was out for 12 minutes can anybody advise what I should do. My GP has not diagnose me with diabetes but says I could be borderline, it's so frustrating I can go for months without having a hypo and then all of a sudden within minutes it comes on, this is very scary for me please help.
