High sugar during exercise?

For me personally, my blood sugars come down after 1 hour after my exercise.

 

That's good! Im not sure if there's anything you can do to prevent the rise because i know non-diabetics who experience the same during exercise and then the drop back to normal after.

 

I think that’s the way the body works. Don’t let that scare you out of exercising, it’s a good thing

 

Yea i consider it like eating a meal. If your working hard your body naturally releases the energy you need from its stores. It should drop when you finish.

 

I was really glad to see your post @Rocinante and all the replies. I’ve just had a similar shock. Although I knew BG goes up during exercise I was shocked to see it had risen to 8.7 today after boot camp ( higher than I’ve seen it since before diagnosis). It was very hard exercise, I’ve only been doing it a few weeks and today was the hardest yet. My BG is usually reasonably well controlled. It had dropped to 6.4 an hour later but wasn’t in the 5s (where I prefer it to be) for a couple of hours.
I think the Libre is great for getting this sort of data and you’ve reminded me I should stick one on before next week ( if I can walk again by then)
Does anyone know whether the height of the spike or the time it takes to come down again can be used to figure out how broken ones metabolism might be. How high do non diabetics go I wonder and what is a usual recovery time?

 

There’s too many variables. I usually drop within 30 minutes but if there’s some stress I.e. sore muscles , recovery time can be longer. I would say that recovery time, and not the spike, would be a better measurement of IR.

 

Thank you, I was thinking along similar lines. I might ask my daughters if they’d mind doing a finger prick next week before and after, to see what effect it has on them. ( they are non diabetic and a lot fitter than me - but at least it will give me some idea)

 

When cycling my bloods tend to stay stable for the first hour then they just drop. I have a sugary drink to sip constantly, jelly babies which I have every half hour or so and I stop off every couple of hours and have a little bit of a carb bar.

When I play football I'm the opposite, I go up like you do with cycling. I have food before hand and I have a sports drink but bloods shoot up and it's a case of checking them more afterwards till they level off again.

Iv come to realise exercise affects us all differently and there's isn't a correct answer.
I can cycle 60 miles casually and be ok but then when I did it pushing hard with a mate I had major issues through the night with really low hypos

It seems to be trial and error with everything

 

@Goonergal and @MarkHaZ123 I guess it is all trial and error and like everything else with diabetes it seems to affect each individual differently. Certainly for me the boot camp on Saturday was more intense effort than I normally use. Definitely out of my comfort zone!
