Diabetes UK says that for non-diabetics BG it should be between 4 and 5.4 fasting, between 4 and 5.9 pre-prandial and under 7.8 post-prandial (which they define as being after 90 minutes), but make the point that the pre- and post-prandial numbers are not part of NICE guidelines.
Interesting
@Martin.A - and the sorts of values that seem familiar.
Though I am reminded that when healthy people without diabetes were studied wearing CGM, while these values were common, there were also excursions outside that range
I guess that’s one reason why fingerstick checks aren’t often used for diagnostic purposes any more. The longer-term picture of an HbA1c gives a more general picture, without the distracting wobbles from time to time.
Welcome to the forum
@jane58 - it’s a great question! Early morning readings cab be a bit stubborn, and can be the last to come down, even when other results before/after meals are behaving themselves. As Martin says, this is often to do with the liver dumping glucose to fire up the burners for the day.
I did my first reading yesterday before dinner and it was 6.3 and then 2 hours later after food it was 7.8. I'd like a good idea of what I need to be aiming for. Or point me to where I need to be looking as everything I've looked at seems to be a bit confusing to me.
That looks like a very positive response for that meal
@ChicagoSoul - many members like to aim for a rise of no more than 2-3 from the pre-meal reading at the 2hr mark.
In some ways, to begin with, the rise could almost be seen as more informative than the levels themselves. 10-12 might seem less than ideal, but it suggests that the body coped better with the food than a meal that gives 4.2-8.5.
Choosing meals that cause smaller and gentler rises in glucose allows the overall levels to gradually drift downwards. And aiming for reliable 2-3 rises should suggest that once a person’s levels are roighly 5s-6s before meals, they will be staying in a good range most of the time.
