I need this post to accomplish two distinct and important goals. The first one will be simple. I want to thank my wife Kelly and my daughter Arden for both being so amazing. You'll see why in just a moment...
Second and maybe more importantly, I want to take this opportunity to remind everyone that while CGM technology is fantastic, it isn't foolproof. Because of that sometimes ignorable fact, we always have to test. Normally when we speak about this topic it's in response to the notion that you shouldn't bolus based on a CGM number. While bolusing without testing is something that we should never do, most of us probably have... but we shouldn't becasue CGM technology is designed to be used in addition to testing, not in place of.
Tonight while I was with my son Cole at his baseball practice (yes I know it's January) Arden's CGM alarmed and reported, "101 arrow straight down". Kelly, being the D-mom rock star that she is, tested.
Please test because sometimes, not often, but sometimes, 101 is actually 36. The DexCom CGM technology is so wonderful that it's easy to forget that it isn't perfect. I've been as guilty as the next person of leaning on it too much when I know that it isn't always spot on. It's difficult not to, especially after the sensor has been on for days and consistently reporting numbers that are so close to our tests. Next time that I'm inclined to think that way, I'm going to remember something that Arden and Kelly told me when I got home and I hope that you will too.
Kelly later said that she tested Arden because Arden said that her eyes "felt funny". Arden told me the next morning that it felt like she had been looking, too long, into a computer screen and then suddenly turned away. "My eyes were getting dark" she told me, with no inclination for how her words were breaking my heart.
I gave her the bolus a few hours before at dinner that caused this low... and her eyes got dark.
Most moments with type I diabetes are uneventful. Our vigilance gives us the sense that we have the disease under control, but that's a foolish notion. It's only under our control until it decides that it wants to run away. When diabetes decides to run you can't stop it. Your best hope is to chase after and keep it in sight until it gets tired of running. Then you can stand next to it again, pretending that you are partners.
We're vigilant because we can't predict when diabetes will take off running, that's why we test. You aren't taking the test, it isn't you that's being judged. It's a test of diabetes, an indicator for whether diabetes is going to stand next to you and play nice or run away.
