Type 1 diabetes and energy loss during strenuous exercise
Well, It took me a while but I finally figured out why I was always so tired and energyless halfway through my 5k runs...My BG was too low!!
What I don't understand is how low BG relates to loss of energy?
For example I take in 100 carbs 4 hours before a run. I take too much insulin. As a result, halfway through my run my BG dips way down to 42 and all of a sudden my energy is zero!
My question is...what happened to the 100g of carbs that I stored as energy?
second scenario....I take in 100 carbs 4 hours before a run. my BG shoots up to 229. I take 2 units of insulin. Prior to the run a couple hours later my bg is 136. I eat a piece of hard candy before I run 2.5 miles. My BG after the run is 60. It seems like I perform exercise better when My BG is high like between 140-160 range starting off. The second scenario is what happened today, and i actually felt great after the run.
So what's going on here? No matter how many carbs I eat and store for energy, my energy is still sapped when my BG gets too low. I guess I'm confused about how energy is used in the body and how it correlates with BG levels. Can somebody please explain? Thanks.

"hard to acquire" is an interesting term, as "hard" means different things to different people? Since it looks like you have a pump already, it'd probably be fairly easy?

CGMs are awesome! :) But do not replace your glucometer, just one more gadget in the handy diabetic tool box. Usually insurance companies look at your A1C and number of documented lows. Make sure to speak with your endo about your interest in one, and they should direct you to the CGM company reps and be able to get the ball rolling for you.

thanks Megan! I'm sure that this device will definetely help me manage my energy on my runs. I'm excited about this! :) I didn't have a problem getting a pump so I suspect that the CGM won't be a problem either.

alright, i'm almost there. unfortunately i'm still experiencing lows during exercise but i'm a work in progress:)
here is another concern that I have though. What happened to my liver?? I thought that it was supposed to detect lows and do a glucose dump when BG gets too low.
Can anyone help me better understand exactly what causes the liver to do or not to do glucose dumps.
if this question has already been answered then please disregard. i'll just look for it. thanks!

and I have an omnipod! It's Awesome!! I wasted a few pods at first trying to figure out the best placement (kept knocking them off). Fortunately, my Diabeetas educator was sympathetic and replaced most of them for free! :)
It's a great device. I believe that the best place to wear them is on the front of the upper thigh(left or right)close to the groin area. Forget about wearing them on your arms. you will knock them off everytime. Guaranteed!
