Overnight glucose average is high with good diet
Hi, I wanted to get some clarity on my glucose patterns because something doesn’t seem right to me.
My A1C is 5.1, and after dinner my glucose may rise to around 120–130 mg/dl, but it comes down to the 80–90 range before I go to sleep. However, once I’m asleep, my glucose rises and stays elevated through the night, averaging around 105. I found this out just last week when I wore a CGM device out of curiosity. Last time I used a CGM was about 6 months ago when my overnight average was 81 mg/dl.
I eat a very healthy diet, mostly vegetables, protein, and then complex carbohydrates like lentils and beans. I’m also active and generally healthy.
It seems like this rise isn’t directly related to my meals. I’m wondering if it could be related to my liver producing glucose overnight. It doesn’t look like a typical dawn phenomenon since it’s elevated throughout the night, not just early morning.
I’d really appreciate your help understanding what might be causing this and whether there’s anything I should adjust or test further.
