A1C low but Fasting blood Glucose above 100
Hi,
This is for one of my friends..
for the last 5-6 years A1C is on the lower side below max being 4.5 but Fasting blood Glucose above 100 ranging between 100 and 115.
Fructosamine test have been done couple of times and they were also with in range all the time.
The other medications they take is for Epilepsy (earlier Tegretol and then Lamotrigine for the last couple of years.
Their Hemoglobin also has been low below 13 for the last couple of years.
Is this normal or Is there anything to worry?
-Thanks

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?
