(Diabetes, full-blown, is defined by a fasting over 126.)
After meals, I've been known to get
as 235 if I ate something like pancakes with syrup, or chocolate cake. Normal meals usually send me to around 145 to 165, occasionally 180.
A1c, without using Lantus, was slightly over 6.
As you can see, none of my numbers are quite high enough to be considered worrisome, but my concern has been to keep damage to the islets of Langerhans to a minimum.
