Exercise - Next Day Highs

[watergypsy]

I'm T2 insulin dependent. I've been really conscious of maintaining good levels for 5 or 6 weeks since I got a Dexcom one+. Yesterday I inadvertently went for a very long walk (10 miles... usual for me is probably 3). It was strenuous and my muscles ache today.
I had a hypo on the walk, and a hypo at 1am this morning. Since waking I'm stuck around 12.
Insulin doesn't appear to want to work today.
Is this normal the day following strenuous exercise, and is my body up to some weird recovery science?

@watergypsy I’m not on insulin. I do exercise everyday. I sometimes go low at night, usually around 3am. I had a low a few days ago, enough to register on my freestyle Libre. I was hovering around 3 (Not a compression low). So not too bad, but it was for over an hour. I did wake up as my blood sugars were rising. I was a bit clammy, but that was it. My liver did kick in and I rose to around 5. I’ve had a lot worse.

If I do a more strenuous exercise then my blood sugars go up during the activity. I’ve had them up to around 11 if I’m going uphill. The long term effects, I believe keep my skeletal muscle mass at a good level. An over all positive for my body despite the raised blood sugars.

As I say I’m not on insulin, so insulin users who exercise may give you more constructive information. My view is from a none insulin user who exercises.

Going low overnight post-exercise is quite common for T1 diabetics at least, caused by increased insulin sensitivity of the muscles and the liver looking to replenish glycogen stores. I tend to run low for a day or two after a massive increase in exercise.

I'd not expect to be high the next day. Could it be the after-effect of your nocturnal hypo treatment? Did it eventually come back down to normal?
