Swimming tonight was pretty good. I did 1.5 km in total. I wanted to do 2 km, but I missed the bus, and the schedule worked out so that I couldn't fit more swimming time in.
At 6:00 I was 7.2 (130) and had dinner, 30g, which I bolused fully for. At 7:00 I turned my pump off for an hour because I wanted to swim and still had about 2.5u of insulin on board. Then I missed the bus, so swimming got delayed.
At 7:50 I was 7.9 (142). At 8:25, right before swimming, I was 9.8 (176). I swam for 1 km which took me 34 minutes (I timed this time) including some rest stops. Then I tested and was 9.1 (164) at 9:15. I swam for another half km which took 18 minutes. After that at 9:45 I was 7.0 (126).
I got changed and stopped to pick up groceries and such on the way home. A while after I got home, at 10:45, I tested at 14.5 (261) and did a correction.
Still trying to figure out the BG stuff, but at least I went tonight on a Friday evening when I got home later than I thought and then missed the bus—and it was raining! Lots of reasons to not go, but I did.
That's tough to have to rely on public transportation to do swimming! Way to go!! When I started running, I'd turn my pump way down (7%, because 7 is lucky. Or 13%) or off more often. These days I don't do that as much as it seems likely to lead to highs more often than not. I haven't figured any of my "numbers" out but I figure if the unit for a basal drops me 40 points or so, if I skip an hour of basal (really, .8U but whatever...) that would boost things about 40 points. I think that having a little bit of insulin can help. I'd probably have corrected the 176 but cut the bolus to 1/3 of the normal amount, to "cover" the exercise? I love to eat when I'm done so I sort of try to engineer a decent number to be set up for that. I'm not shy about bolusing during exercise, often very small boluses. I did several .3U at a time during the marathon, they didn't work that fast (Gatorade on board too...) but eventually, when it started to come down, it seemed to be a pretty soft landing. I think the 176 to 164 to 126 numbers swimming are GREAT results though. Very flat for 1/2 hour and then the drop, which could be managed very nicely with a small snack if it were say 150-140-110 or something a bit lower on the scale!
I think it was okay during swimming, could have been better afterward! I was 14.5 (261) at 10:45 which I corrected fully, and then 16.6 (299) at 1:00 which I also corrected fully, and then 11.8 (212) at 3:00 which I also corrected fully (minus IOB of course). Then I was finally 4.2 (76) when waking up at 9:00. I think my A1c is going to go up from exercising if this keeps happening! LOL.
I don't exercise for my BG, I exercise for my heart rate!! It's great to go to the doctor and the nurse takes my pulse, usually after I'm weighed, in clothes, which sucks as it adds 7 lbs, and goes "your pulse is 52, do you run?" instead of "you have DIABETES" and it always makes me happy to be a "runner" rather than a "person with diabetes," although I'm sort of proud of that too...
