Blood sugar rise after excercise?

Hi everyone
I have been VLCHF for 15 months now. Something has changed in the last couple of weeks. I now experience a rise in bood sugar after a visit to the gym.
My basal level has remained the same for more than a year and levels are reasonably good. HBA1C 2 weeks back =5.4
Exercise days start at 0730 with a blood test, 7,3 this morning so a bit high.
Dawn Phenomena dose would normally be 2.0 so I took 2.5 for a bit of correction and out to the gym.
After 10 mins on a cross trainer BS=8.2. Keep working. After another 15mins BS=9.7. In frustration took a correction dose of 2U.
After a couple of hours my levels were still high 7's and I had eaten nothing yet.

This is has happened a few times in the past couple of weeks, but before would have been an unusual response for me. I switched both insulins for new cartridges just in case a couple of days back just in case that was the issue. It seems not.

I am wondering how this BS rise is generated and why. I am running out of ideas now.

Any suggestions?

I'm on keto and happens to me. Will be glycogenolysis. Your liver making glucose from protein for energy.
Well that's what I was told anyway :)

Hi @StewartH this happens to me too, although every day is different. This morning I found I had to keep my post-swimming hike in pump basal going for 4 hours rather than my (usual but not exclusive) hour and a half.

The pool was more crowded than usual so perhaps I swam slower. And I might've spent longer in the shower than last time I went, because today was hair wash day - and that means of course being disconnected from my pump for longer.

And sometimes - it's just because. Because it's raining, or Monday, or March, or just because life wants to make itself noticed. All of which really cheese me off.....

Yesterday I went to the gym and just rose and rose - okay, so I went at a different time of day to usual, so was expecting some different results (I'm trying to write my own Snapsy-special textbook of what to do for what exercise at what time of day, factoring in every single factor under the sun - I think that particular work in progress is destined to be an unfinished symphony) - but I was higher throughout than I usually am, had just the right amount of correction insulin to steady up afterwards...... then fell asleep five hours later without having cut my basal in anticipation of the several-hours-post-exercise crash. Woke up 2.9 and really, really cross. Oh the joy of the rollercoaster!

Nice HbA1c, by the way!

I have the excactly the same problem... I think that´ll mean we have to really eat enough protein before and after excercise ... so that the body will not take too much from our muscles... :shifty: actually a bit disapointing to get home an find ones numbers have not gone down after that much effort.... but usually I have notised that my blood glucose drops in the evening after daily excecise...
 
I'm a type 2 and if I give it me all in the gym I experience the same issues, I tolerate in the belief that there is a net gain health wise. Conversely if I walk gently for an hour or so my BS drifts down.
I guess its a way of telling me there is something wrong with my body :)
