Some people have really good fasting levels, but very bad post meal levels. When you average the two, it seems OK. I say 'seems'
To make this simple, imagine you having good fasting levels a good part of the night and some of the day.
Let's say 10 hours of the day at 90.
Let's say you have bad post meal levels. Let's say you are at bad levels, 4 hours of the day (post meals), something like 160.
Let's say the other 10 hours are around 110.
That gives an average of 110 overral, which is a 1ac of about 5.2
That 5.2 looks great, but those 4 hours at 160. Those are the bad ones. At these levels, you are damaging your pancreas, slowly, but surely.
An 'average' 1ac with good fasting numbers is a sign of something bad on the post meal numbers. The met may help you with those post meals.
