Oh well that's OK no need to worry then. So when the Blood sugar checker on this site tells me I'm Hypoglycemic from now on I can just disregard it
John, whilst you are just taking Metformin it is ulikely, although not impossible, you would suffer a hypo, and even more rarely likely to suffer from a hypo that could endanger your own life (leaving aside the driving issues here!). Fortunately, our livers, and functioning pancreases try to rescue us of we dip a bit lower than usual.
Overall, my bloods naturally run pretty low these days, and I see 3s most days, based on finger prick testing, and almost all days if I am sporting a Libre at the time. My body just seems to run that way since I trimmed up my body and carb consumption.
Not everyone sees 3s, and it's no big deal for those who don't. We don't have to be in the 3s to be healthy. Indeed some non-diabetics would see 3s if they tested; some wouldn't, just depending on how their individual bodies operate, but clearly, few non-diabetic folks (who have never been diagnosed) test regularly.
Listen to your body. If you feel off; don't drive, irrespective of what number your blood meter might say.
Should you ever start taking insulin, then all bets are off and the overall game changes.
