I had a really active weekend last weekend - snowshoed for an hour on Saturday, then got lost cross country skiing on Sunday and what was supposed to be an easy 30-45 minute ski turned into an hour and forty minutes. It wasn’t horrible, I didn’t feel excessively fatigued or anything afterwards, and I enjoyed really good blood glucose control for the rest of the day.
Imagine my surprise when I woke up the next morning with a blood sugar of 137 (it’s usually between 100-120 lately). It stayed high all day.
Nothing but the exercise was particularly different - I didn’t binge on carbs or anything.
I was just reading about the Somogyi effect, and I’m wondering if that’s what happened to me. Could it be that the exercise pushed my blood sugars down far enough to trigger this? I’ve checked my blood sugar a couple of times in the middle of the night (but not that night unfortunately) and it’s always been fine. I have woken up a few times sweaty and with a rapid heart rate… which I just read can be a sign of a rebound.
I’d assumed I wasn’t having Somogyi effect because my glucose was fine, but if I was already in the rebound stage then that’s not a real indicator.
If it was Somogyi, should I make sure to have a snack before bed on the days that I exercise a lot? Lower the Lantus (currently the only insulin I take is bedtime Lantus)?
I will be asking my Endo about this, but unfortunately he’s out of town until February
