I've just got my first cgm. It started working an hour ago and my BG was 48, and dropping. I ate a 25g candy bar and have spent the last hour delightedly watching it climb - 88 and counting (it's leveled off now, so I'm going to have my normal dinner and shot). This is amazing; I've been Type 1 for 35 years and have no awareness of low blood sugars - often find myself collapsing out of the blue and discover I'm 20 or lower. The one challenge is going be the fact that I live in a Zen temple and spend 90 minutes every morning meditating in a perfectly silent room with 50 other silent people. I take a morning shot of Humalog to deal with the Dawn Phenomenon, and am often low by the time we're done meditating. But I'm determined to make this work; I think it's a life-changing piece of technology.
Glad you are finding it useful...just be careful on the first day of wear... it tends to be less stable and off more than on later days (for me, anyway). And always do a fingerstick before dosing insulin... sometimes it is way off.
Thank you for the suggestion. Don't believe everything I read on a screen, huh?
Wow, it just buzzed cos it went back down to 69, but when I tested it manually it's 99...
That's the kind of thing I was referring to....but it does get better over time...
And then it lost coverage... and now it's telling me it's 59, but my manual test says 81...
I'm glad your first hour was so good for you. Did you compare with your glucose meter to see how close they were? I rarely get any accuracy during my first day. I usually get two weeks from a sensor, but I never take any insulin or eat anything based on my Dexcom numbers. I always use my glucometer to decide my insulin dosages, and to decide how to correct my highs.
Oh, I see - it's been telling me 41 for the last hour, but my meter says 112... does that mean it's not working properly?
It's working. The Dexcom needs to get used to Your glucose monitor. Give it time, but if the Dexcom is reading low prick your finger to double check it. Your diabetes sounds like mine. I've had the same issues with lows and I live alone. Let those other 50 people know what's going on with you as I'm sure you have. You are going to love the Dexcom just for those lows.
Thanks, Katie - I input my monitor reading and now it's way high.... And you're totally right, those 50 people are all my friends, and they'll be happy to support me in this. And I think they're tired of me being chaotic.
Djinn, I need to do this for my co-workers and you might want to as well for you fellow Zen partners. Go to diabetesnet.com and print out the description of Hypoglycemia Unawareness. It really explains what is happening to us in a way that the non diabetic world can understand.
Scroll down and look at the bizarre behavior section. Here it is.
A person's actions during HU can be bizarre with:
anger or irritability --- see also Anger During Lows
insisting they "feel fine" in the midst of very unusual behavior
laughing and silliness
Thank you, this is very helpful. I've just been to a staff meeting where I explained all of this to a group of my colleagues and they were wonderfully supportive. Of course the Dexcom started buzzing this morning during meditation, and I put a jelly in my mouth as quietly as possible, but it buzzed again - I was so distressed! I had the fall rate alert disabled, but it went straight to Low, so it wouldn't stop. The trial Dexcom I have isn't working properly - its beep isn't sounding, so I'm kinda thankful for that. But I'm realising that I'm taking too much fast-acting insulin in the morning to counteract my dawn phenomenon.
