This morning I got up an tested my BS it was 95.
Then I jogged 3 miles. Drank a cup of black coffee (nothing in it) and tested my BS. They were 129.
This happens every morning. What is going on? Some morning it is high as 140.
Any suggestions?
Thanks for the help.
Hey Buddy. There is the "Dawn Phenomenon’ where many people’s blood sugar rises in the morning, as they are getting going after sleeping. Exercise will also stimulate the liver to release more glucose into the blood, and it may take a while to come back down, especially if we are insulin resistant.
There are several reasons this might be happening. Here is a info on a few.
I have the same issue and I am still looking for the cause.
This looks similar to your question:

Question I have is that whenever I test my own blood sugar, it’s usually triple digit, and almost always above 80. When I had a lab test it, it was 86, but my A1C was in bold for being too low, 4.6, which I guess isn’t “too” low, but is below the lab’s reference range. I wish I knew what was going on.
If you do a search of “physiological insulin resistance versus pathological insulin resistance” I think you may find your answer to this question. As long as your bg levels fall consistently during the day (after your run) it shouldn’t be a problem. When some people are fat adapted there is a glucose sparing effect that can cause higher levels in the morning that then fall throughout the day.
