Daisy Mae's swimming BG thread


today my BGs were running high when i began my prep of ZB. i pre-bolused a little heavier (.5 units) and decided to leave for the pool 40 minutes earlier than usual. this meant that i would start swimming 30 minutes sooner than usual, which meant i would have been on ZB LESS time than usual. a little daunting for me. kinda expecting a crash, but figured i would work it out. Eric told me something recently which has emensly abetted some of my pre-swim BG anxiety: take everything just a 1/2 hour at a time. look at the circumstance, consider the big picture, and make a decision based upon that; dont bother yourself with the idea of swimming for 90 minutes…just the half hour. each half hour will require a new decision and a new action. today, this was put into play, and i was shocked and pleased with my results. but it did take a lot of faith on my part.

so when i was ready to start my swim, my BG was 138. no gtabs necessary for that first half hour. but when i i got out of the pool to test, my BG had crashed to 103. now what would i do if i were starting my swim with a BG of 103? i would definitely take 1 tab; so thats what i did, and then i got back into the pool for another 1/2 hour. when i got out and tested, my BG was 106; now, at this point, i had been on ZB for 3 hours. i KNEW i didnt need any more carbs, so i just jumped back in for another 1/2 hour. when i got out, i saw how my decisions paid off: my BG was 100.

now i would have prefered NOT crashing after the first 1/2 hour, but i saw that it was possible to manage a safe swim without dangerous reprecusions so long as i was able to break my swim into several pieces. if i just looked at one aspect of the big picture, i would have had a lot less courage and a lot more anxiety. this was a new experiment for me, and new experiments can be frightening.

tomorrow is another day. i will get to try out another experiment. who knows what will happen, how it will go; i know one thing, though, and that is that i can be flexible and adjust. i have a plan. :wink:

here are today’s stats:

11am bg 83 0% TB and pre-bolus of .4 units
11:30 bg 98 (ugh oh, bg going up too fast; bolused another .1 unit )
12pm bg 104
12:30 bg 126 (OMG! how did that happen??? Grab my bag and leave for the pool)
12:50 bg 138 no tabs needed, just jump in and swim hard
12:50 bg 103 (OMG! major crash. took 1 Gtab and jumped back in)
1:20 bg 106 (phew)
2:20 bg 100 (got out and bolused 2.1 units to replace 3.5 hours of ZB)
2:50 bg 83 bolused 1.4 units to cover Boost re-fuel shakes (bolused LESS than i ever have in the past b/c i have been swimming hard this week and my BGs are trending low and crashing too often. i have also adjusted my dinnertime ICR AGAIN!!! i need so little insulin after consecutive swims.)

so today provided me with a lot of new lessons. i really hope someone can benefit from this. one HUGE thing i learned today: I dont need to be afraid so long as i can muster up the courage to be UNLIMITED (and, like ERIC so profoundly said in his latest thread: “I AM POSSIBLE.”

This is a great way to look at it! I’ll have to incorporate in my workouts, too!

You nailed it today!! :sunny: Being flexible is the way to go!

OMG. i survived an evening, overnight and second day of BG nightmares.i couldnt stop crashing. i turned my basal down to 90% and drank a gallon of apple cider, peacan sandies, chocolate, glucose tabs. nothing worked. i was up all throughout the night just testing and fueling. and yesterday was barely better. then, i think b/c of all the carbs i was pounding into my system to make up for all the lows, it hit me all at once at 1am (2 nights in a row, same time) : a bg of 184, and then a bg of 158 the next night. i did IM corrections which worked as usual, but then the same problem repeated itself the next day: one low after another without much success at bringing them back up.

so i lowered my basal profile. and today has been a little more successful. so far one high after an over-correction. and then i am waiting to see what today brings (especially since i didnt swim yesterday). i plan on making up the missed swim day by swimming tomorrow (something i never do, swimming on a Sunday/weekend day).

i will report back later to let you all know how my day progresses.

has anyone else had this problem??? i need helpful ideas and suggestions and Eric is away :rofl:

thx in advance,

Sorry, a bad couple of nights! Is it because you missed a few days swimming? It is hard to adjust basals when activity levels change. I sometimes think that insulin stays in the system MUCH longer than documentation suggests. This happens to me, too, if I miss running for more than a day in a row. I tell myself to do SOMETHING, but being human, I don’t! Bad, me!! :grimacing: I guess you could go biking or some other activity if you don’t want/can’t swim on the weekend, just to keep your basals consistent with your swim days?? Hope you have a better evening and overnight tonight!

Sorry, I just edited my reply @daisymae!

just the opposite; i swam really hard 3 days in a row, and by the 3rd day, BAMM! trouble!!!

do you have different pump profiles for your running days/non-running days? easy/hard running days? i try and rate my swims in regard to difficulty. even though i always swim for 90 minutes, sometimes it is a harder swim than others. (then i know it will bite me in the A** that coming evening :wink:)

(and truly, i should buy stock in Ibuprofin :laughing:)

Oh, I’m so sorry, I thought your original message was from 2 days ago, so I was thinking you missed swimming!! Sorry!!!

No, I use the same settings everyday, and same for all 24 hours. Keep in mind, I’m now on Loop which gives me temp basals up to 3x my max schedule basal (0.5U) as well as reduces the basal as much as ZB when I’m predicted to go under my target (correction) range. However, even before Looping, I used the same basal, ISF, IC everyday, each hour of the 24 hours. It’s just before Looping, I manually did a lot of temp basals to compensate for the activity difference in run days!!! A lot of work, and I think this is what you are going through!!! :frowning:

Yes, I know, some days running is also harder on me, too. I don’t know why, but maybe weather, recent diet change, eating/going out, insufficient rest, …?? Yes, my fallback is Advil, too, but try to limit it!!! I hope you do not need it too often!

it is a LOT of work. thank you for understanding. now i dont feel so all alone and nuts. I felt like i was going to rip my hair out!!! :rofl::crazy_face::sob:

PS: i stopped taking Ibuprofin 2 weeks ago. i became certain it would give me an ulcer.

Yes!! That is why I try to limit it, though when I do take it, I usually take 3 all at once, and mostly during the night so I can sleep through the pain.

I know you do not use Dexcom CGM because it doesn’t work well for you and I’m not sure which pump you use, but I have to say DIY Loop has made a world of difference to me, esp for this very issue, changing metabolism due to activity causing changes in basal needs.

I am now using the Dexcom G6 and it is much more accurate than the G5. I also started using it on the back of my upper arm, where there are fewer failures. I don’t know if you tried the G6 but if not, maybe you want to do a trial of it.

I only make this suggestion to you because it seems we are pretty similar and it may have similar good results. :sunny:

i take the prescription ibuprofin which is 800 mg. i take it with two Tylenol Extra Strength and it works like a charm. i havent taken it in about 2 weeks now, and i have just sucked it up with the pain. (eric’s suggestion) :grimacing:


i dont even know what LOOP is. i am completely ignorant :frowning_face:but the problems i am having are exactly as you described. different activity levels, different insulin needs. this morning everything was ending up in a terrible crash, then the later afternoon came and POP, BG 191!!!
knew it was time to reset my basals to sluggish profile. gave myself an IM shot in my left calve muscle and walked about my home with a bottle of water in my hand, guzzling while exercising my calve muscle. :crazy_face: of course it worked in about 15 minutes, bringing my BG down to 130. i know that is above my target range, but its certainly nice to feel that i have some control over the situation.

PS: but tomorrow i will be in the pool again and hopefully i will find a nice balance with my insulin/basal/bolus/ICR/SF needs.

after my 2 days of BG Hell, my husband encouraged me to swim on a Sunday. i usually try and avoid the weekends b/c they are so busy and the crowds are miserable. but i took his advice; he knows me over 26 years, and knows what will set my ill at ease straight again: swimming. ALWAYS SWIMMING!

well miraculously, my BGs were stable overnight (after many manipulations of pump basals), and my morning was wonderfully uneventful. at 6am i began to prep for my swim. my numbers were nice and flat and steady.

i truly thought that the pool would be very crowded, and my fear was that i would have been on ZB for 2 hours and when i got to the pool, there wouldnt be a free lane and i wouldnt be able to swim. well the pool was empty!!! :grin: it was right there just waiting for me. and i had one of the best swims ever. all my angst melted away. all my agrivation, frustration, and anger disolved in the water, and i was ME again.

here are today’s stats:

12:30 bg 91
1pm bg 105
1:15 bg 111 (took 1 tab and jumped in) (2 hours and 15 minutes of ZB)
1:45 bg 108 (took 1/2 tab)
2:15 bg 105
2:45 bg 104 bolused 2.5 units (who the heck knows if that was enough, not enough, too much, just right???)
3:15 bg 91 bolused 1.4 units for my Boost re-fuel shakes (again, who the heck knows if this was sufficient or not. i’m just trying out new insulin dosing to try and avoid evening crashes)

tomorrow i wont be in the pool (MD appointment in the City) but i will be back in on Tuesday, Wednesday and Friday and next Sunday) I am praying that my evening goes well and that my BGs remain stable. One moment at a time. One step at a time. One day at a time.

well it worked!!! yahoo!!! yesterday, after getting out of the pool, i used a 97% TB which lowered my basal rates by .025 u/h. i had no spikes and no crashes at all. how wonderful is that??? a total evening and overnight and day (today) of in target flat line.

i didnt swim today, but i was doing a lot of walking around Manhattan, so i did a 95%TB for about 4 hours. that worked out perfectly as well. never went above 106 nor below 81, and i was hopp’in and bopp’in :wink:

tomorrow i will be back in the pool, so i am really looking forward to that, and i will be able to see if what i did last night and today will be as successful tomorrow. will keep everyone posted. :sunny:




what a GREAT freak’in swim i had this afternoon! my prep went perfectly, for starters. a total in target flat line from ZB start to finish. at 11am my BG was 91, and at the end of my swim, my BG was 105 (and that’s 4 hours of ZB !!! )

i took 1/2 too many Gtabs after my first stretch, though. now i know for the future (like tomorrow’s swim, for example :blush: ). but other than that, i dont think i could ask much more of myself in that regard. i am so excited about this!!! and my plan for tomorrow is to swim a bit harder and faster, and i would also like to do a 1/2 hour of kick boarding. today, i was too sore from my last swim, that i couldnt push as much as i would have liked to, but C’EST LA VIE. :sunny:

here are today’s stats:

11am BG 91, turn off pump
1pm BG 97, dash to pool

1:20 BG 103, took 1.5 Gtabs and jumped in
1:50 BG 91, took 1 Gtab (should have only taken a 1/2 or even nothing)
2:20 BG 90
2:50 BG 105, bolused 2.4 units replacement basal
3:20 BG 73, bolused 1.2 units for 32 gms re-fuel (taking a guess here with reduced bolus amount, b/c i am trying to avoid a crash later; and, i am on a 97% reduced TB, which worked for me both Sunday and yesterday; i may need even less, but i’ll test frequently and find out.)

will keep you posted on how this evening, overnight, and tomorrow goes. and i’ll be back in the pool tomorrow :smile:

started crashing at 4:15…appox 1 hour post last (minute) bolus. went down to 54, took 2 gtabs, and lowered my basal profile, giving me even less insulin (95%). we’ll see if that does the trick. if not, then i will lower it again even more.

Or take more glucose? The sooner you can restore your muscle glycogen, the sooner your body will stop vacuuming all available sugar out of your bloodstream.


thanks for the reminder. i recovered immediately after having some glucose tabs, followed by a hearty dinner. (ate some of my husband’s too b/c he had some dental surgery today and couldnt chew much of his own :yum:)

now just chill’in and feeling fine. last BG was 96. hopefully it will be smooth sailing from here on out.
