Daisy Mae's swimming BG thread

you are too kind :blush:

now would you please give me your address so i can send you a cheesecake?
it would be my pleasure to know you’re enjoying one; and i would know that you would be fueling up for your next run. and, i would love to see your dex graph while you are eating it :wink:

at 7:50pm i crashed down to 40. i ate a very hearty dinner and bolused very modestly for it. i think i over-bolused for my “replenishment” of basal after my swim today. (i only gave myself 1.8 units after being off of my pump for 4.5 hours with a bg of 151)

i just had a lot of apple cider and the best best chocolate in the world: Lindt Dark Chocolate with Sea Salt. i know it may sound discusting, but trust me when i say that as far as packaged chocolate goes, this is incredible…and it barely raises your bgs; in fact, it kinda stablezes them the way peanut butter does.

I PM-ed it to you!

It’s interesting to compare. Today I finished at 64 and immediately gave myself 4 units. But I did not crash. Because…I drank tons of chocolate milk right after. :stuck_out_tongue_winking_eye:

what was the title of the PM? i cannot find it.


so i went to see my endo this morning and i just got home in time to turn off my basal (bg 91) and give myself .4 units + what was left OB from breakfast (totaling .7 units)

its a little after 11am wednesday morning.

Endo Experience: he was actually very pleased with my BGs; my A1c was a little high (6.4% ) but he was very happy with that as well. he deffinately noticed on the graph when he downloaded my meter the day that i drank the full powerhouse of regular tonic water. but all in all he was happy with all things. he felt very strongly about my sensitivity factor being too high; he said what i thought he would say: he wanted to lower my sensitivity factor b/c since i have been exercising, i am responding to insulin much more strongly. so instead of it being 55, he turned it to 60 (which he claimed was not a large difference, but what the heck do i know about those numbers; i haven’t changed my sensitivity factor since i’ve been on the pump.)

he put a 2 week, waterproof sensor on the backside of my left upper arm so that he could monitor all of my bg levels and i have to maintain a journal of everything i eat and all of my finger stick bgs before and after all meals and log in my snacks. this awta be interesting. (its kind of like the dex sensor, but there is no receiver to watch; it will just stay there for 2 weeks until i see him and he will download it. fancy, huh?


That’s possibly a validation that we are on the right track. :wink:

More important question…are YOU happy with your exercise routine? That’s the biggest validation of whether it is good.

You’ve come a long way in the past few months. You are not a scared little diabetic mouse, you are a lion. :lion: And I love to see it.

Check the quote page today.

sorry, i pressed the wrong button :blush:

Continued: (endo did not like my exercise routine, specifically the prep and why i have decided upon the way that i prep.)

he specifically disagreed with me regarding how long i turn my pump off for before i begin swimming. (he did NOT agree with Eric’s approach :wink: .)
he couldn’t grasp the simple math of it. he did NOT think i should be off of my pump before i swim for more than 1 1/2 hours. i told him 2 1/2 was necessary or i would crash after an hour in the pool. anyway, that was the only disagreement we had. he made me an appt for 2 weeks from today and said that the sensor will monitor everything and that we will get a good look at how my swimming plan works (or doesn’t) F- him. i tried his way, and his way DID NOT WORK. so i go to plan B. (EXPERIMENT : 17 )



I suspect that when he see’s your bg’s around the exercise he will learn himself something. Your approach appears to be working wonders and allowing you to manage a very aggressive exercise routine in with your other activities, and doesn’t appear to be putting you at risk of anything during that additional 1 hour, but what do I know, I didn’t go to medical school :wink:

I think he’s concerned you could get ketotic with more than 3 hours off the pump. Many diabetics do. But insulin also has a duration of action anywhere from 4 to 6 hours, so you clearly have some circulating insulin. Maybe it would reassure him to do a quick blood ketone check before and after your swim to show you’re not getting ketotic with that time off the pump.

But in general I would agree with everyone else…you have to follow the plan that works, and in general I think the exercise insulin management routine is above the paygrade of most Endos.

i AM happy with the progress that i have made. unequivocally.

i am happy with the progress that i have made. it is slowly working, and from all of the notes that i keep, the proof is right there staring back at me; it is undeniable.

i told my endo that i did not want to be either defined by my D or limit my life and my goals b/c of my D, and he wasn’t thrilled with my attitude ( which i have gotten from all of you guys and this particular website )

(anyway, Eric, i will PM you with more of the ridiculous details.)

and onward i press :smile: .

my CDE believes that during my time off of the pump, my swimming is acting kind of like a basal would; the exercise is keeping my BGs steady. i don’t go high when i am swimming, unless i eat to many of those sneaky little swedish fish :wink: .

its funny that they work in the same office and have such a repor with one another. but she is very strong willed and does not let his opinions scare her from expressing her own.

after all the many years that i have been with him, he still does not believe that i need to take insulin to eat protein. i MUST count 10gm carbs for any serving of any protein…even the ones you don’t think i would need insulin for. (and he’s a T1D also. you’d think he would be more open-minded)



Swimming is not replacing insulin, but it is amplifying the small amount of insulin you still have in your system.

The other thing that is helping you is the increased carbs you’ve been eating. It allows your body to use more stored carbs (muscle glycogen) instead of only relying on blood glucose for energy. That is reducing your drop!

Compared to the previous method - eating enough to start at 200, having much more insulin in your system, and then plummeting 100 or more points while you were swimming - your new method is way ahead.

Once you get the other things figured out - like the mini-bolus before you finish, and the post-swim bolus, and you get comfortable starting a little lower - watch out A1C!!!

BTW, do you think his change from 55 to 60 is right?

so, the way i think of it is like this: every different type of tissue in your body needs a different amount of insulin to function – your kidneys need some, your muscles need some, your fat needs some, your liver needs some.

Normally, the amount of insulin you need to keep your blood sugar steady exactly lines up with the amount that each of these tissues need to function properly. BUT when you are exercising, your muscle is able to take in more sugar from the blood with less insulin. That, however, doesn’t mean your kidneys or your fat or your liver need any less insulin – they may even wind up needing more. So there can be this weird mismatch – your muscles are helping keep your blood sugar steady and level, but meanwhile your kidney or liver tissue could be cranking out ketones to compensate for what it perceives as a lack of insulin.

With our son we’ve seen that he can develop HIGH ketones even with perfectly normal blood sugar over night – sticking close to 100 – when his pump was accidentally suspended. He was in the mountains at altitude, so what we think happened is that his muscles and his heart, etc. needed more blood sugar to function, but all the other organs still need some insulin, so he developed high ketones.

In fact, just last night dad forgot to plug his pump back into his site after bath time and he woke up with a blood sugar around 200. That’s for sure high but it’s technically “in range” for him, and he was basically steady at that number or lower all night. But his blood ketone meter read 3.2, which is high. I reconnected and gave him his breakfast bolus without thinking, and then set a high temp basal. He actually went LOW after that but when I tested his ketones an hour and a half later, they were still 1.4, which is still high.

Anyways, all that is a long-winded way of saying that if you check your ketones you will have reassurance that you’re not developing ketones. Even if you are it’s something that can be managed of course. I don’t think the answer to exercise is “swim at 200.”

after 2 hours of no basal , my bg has only come up to 114, so i ate 2 sedish fish and am waiting another 1/2 hour before i test again.

a little nervous, despite all of YOUR proof that i could do this at such a low bg and remain stable. ugh.

just re-tested after 20 minutes; my bg was 130, so i am off to the pool.

please all say a prayer for me and wish me luck. i am fearless, but nervous at the same time. (eric, if you are reading this post, i am counting on you :wink: .

You will be fine!

The trick to not spiking too much from eating a bit of sugar before you exercise is this - eat it RIGHT before you start swimming, not 30 minutes before.

So right before you start, check and take more if you need it. And also check while swimming and take more sugar if you need it then.

11am bg 91 ; turned off my pump and gave myself .4 units bolus
12pm bg 86
1pm bg 114 (ate 2 swedish fish to bring my bg up pre-swim)
1:30 bg 129 walk to the pool (15 minute brisk walk)
1:50 bg 153 ( oh those pesky fish; next time i will only eat 1, not 2)
in the pool; start swim
2:30 bg 137
3pm bg 114
3:30 bg 125 (why up rather than stable or lower?)
out of the pool, 1.5 hour swim (short one today) took .8 manual units by pump
walked home (another 15 minutes) briskly (almost a jog :blush: )

home now. at 4pm bg 99. seemed to be very insulin sensitive to have responded that quickly to the modest .8 bolus post swim.

about my swim today:
started out at a medium pace. long stroke and glide; 2nd half hour swam at a faster pace, shorter stroke, upping the anti to feel the burn in my arms and legs, last 1/2 hour, faster pace, pushing myself, b/c i knew it was going to be a short swim today and wanted to make the most of it.

its funny that now a 1.5 hour swim seems short to me. very easy to accomplish. i remember when i began this exercise journey, 1 hour was a challenge. now, the 1st 1/2 hour seems more like a warm-up to me. isn’t that nice :smile: .

btw: my pump has been set for a TB of 120% 24/7 for the past 3 weeks. i seemed a bit insulin resistant. then, for whatever D reason, it was too much, and now i am back to 100% basal. this is a crazy disease :wink: . must be on top of it constantly. thank God for all the notes i take and keep (for reference) ; they are a very useful tool for me. (also, i can whip them out at my endo’s and show him how crazy and misunderstanding he is :tongue: .)

all in all, a good day for Daisy Mae :smile:

now i would love to hear from all of you !!!


Maybe you should eat the fish just before you jump into the water or a little closer at least to the swim?
