Need help

Hi I’m new here but need help.
Can’t seem to control my sugars.They increase after exercising. Yesterday my sugar pre-swimming was 186 and after swimming it was 275.
Same today too pre - swim 145 and after swim 270

The same thing was happening to me too. I am on a swim team and a couple of times, I would go into the pool with a blood sugar of about 250 or so, then when I got out of the pool it would be about 300 or so.

something that i recommend is that you put on your temp basal if you are on a pump about and hour or so before you start exercising.
