This post is a reminder that you should not be so hard on yourselves when it comes to getting 'diabetes right'. ESPECIALLY when it comes to exercise!!
I exercise the same time Monday-Friday, 5am, fasted (for those mums out there wondering how the heck I do this, I have one child, who sleeps through the night, is relatively self sufficient and a husband home in the mornings to get her ready for school). This week I did a 1hr spin session Tuesday and Wednesday, 1hr yoga session Thursday, then back to 1hr spin Friday. I started all sessions with a BG within 0.2mmol of each other.
Tuesday was the first day of exercise with the pump and CGM. If I had type 1 diabetes, you could say I 'had a low'. I dropped 2mmol, to 3.2 within 20 minutes of starting. The pump suspended me and I stayed at this level until about 30 minutes after I finished the spin session, when I slowly began to rise.
Wednesday I started a spin session at the same time, fasted again and at the same BG. This time I held steady for the full hour and until I ate breakfast about 1.5hrs later!
Same exercise, same starting BG, totally different scenario.....and that is with a functioning pancreas!
Thursday was yoga. Again I started fasted and at the same BG. I suspected that with yoga my BG would stay pretty steady, but no, of course not, it increased!
This morning was back to a spin session, again fasted but starting at a slightly higher BG. This one was all over the place!! I went up in the first half of the spin session, down for the second half and then up again after the session, to 2mmol higher than I was before I started!!
What is also interesting is that the day I did yoga (as opposed to spin) I ran over 1mmol higher all day and over night.
I am obviously unaware of these BG variations in my daily life, and I am blessed to not have to consider them at all. However, this experience is allowing me to see how my body's insulin works, and how differently it works every day, even in identical situations. If the gold standard is a functioning pancreas, then what really is the gold standard? If my pancreas can't get itself together and work the same way in the same situation, then how can we ever expect someone with type 1 to manage this with an external insulin source!! How can someone with type 1 expect to find patterns and rely on past experiences?
Maybe sometimes you will be able to, maybe sometimes you won't. The point is, don't get yourself down if you don't get those magic numbers. Not even my pancreas seems to know what it's doing 100% of the time!
