Is 4.9 to low to go to bed on please
According to your progile you're on Gliclazide. Is that still correct?
If so, it might be a bit on the low side if this is lower than usual for you.
If you're not on glucose lowering medication like gliclazide or insulin this is a perfect level.
Please contact your HCP on what is the right course for you, as we're all different.
