A1C low but Fasting blood Glucose above 100

This is called “ The Dawn Phenomenon”

It’s the bodies normal action to get ready for the day by the liver releasing stored glucose. Very normal. A non diabetics pancreas takes care of this rise whereas diabetics can’t and you see the rise. You are not alone.

I have dawn syndrome. It makes my first check of the day to be around 130. My pre lunch will be 95. My a1c is around 6.5 to 7.5 depending on how "bad" my diet is. The doctor says go by your a1c. He says it is like a snapshot for three months. I early on did a complete test schedule for two weeks to see when my up and downs were. I discovered my dawn syndrome ... Also could see the impact of exercise and food binges. Try it... It will settle your mind about those "unusual" readings. I'm currently around 7.0 and considered under control.

It's either "Dawn Phenomenon" or "Symogi (spelling?) Syndrome". Essentially, your body is trying to wake you up with a boost of glycogen, or you are going low in the middle of the night and your body releases glycogen to keep you safe.

The only thing you can do is experiment when you should start fasting for the evening, or make sure you have a nightly snack of protein and a slow releasing carb. Also, maybe test yourself just before eating breakfast, not right when you get up?

I go to bed blood sugar 108
Wake up to 170 🤔

@tomlowerbs
I have heard of the dawn phenomenon. I’ve looked it up. Might be worth checking it out and monitoring that BS . There are ways I think to help it.

I'm another dawn guy, A1C averaging around 5.6 for years, my morning pre-breakfast reading is usually 110-120 or even a little higher generally after 11-12 hours of fasting, but my pre-lunch and pre-dinner readings average much lower, say in the high 80's.

Wasn't always the case, first couple of years I was dealing with this, about seven years ago, my morning readings were same as later ones. Still, all in all, I'll take it and it seems mostly harmless.

There may be something to do do address this, maybe some specific dietary items to avoid because they metabolize slowly - but I don't seem to know what they are, lol. A late night snack (around 10 carb) may help - or hurt. I tried it and for a while it seemed to help, and then it didn't.
