Time To Go

How  do you know when it’s time to go? When, despite numerous blood glucose  checks and calibrations, and despite eating and waiting over an hour for  that little dotted line to move – I am rewarded with ‘LOW’. To be fair,  I believe this is Day 11 of this sensor run, 4 days beyond the  documented length of use recommended by Dexcom proper. But let’s be  honest, who stops after 7 days? Leaving cost aside, the competitive  nature in me is enough of a motivator to see how long I can get one of  these things to last.

Of course, I'll still try to make this one last

Dear Dexcom, I think it's time to go...

It’s interesting to think about how my interpretation of this data changes depending on the lifecycle of a given sensor. If this were the first 12 hours I would just attribute this to growing pains. But on day 11 or 12, my tolerance for shenanigans decreases and I have to begin to realistically think about a new sensor. With  this recent behavior from Hal Jordan, I think I’ll be starting a new  sensor tonight. For those of you keeping score at home, this was the  last sensor in my first official “3-month supply”. I’ll have some more  thoughtful impressions of the entire Dexcom Seven Plus Continuous  Glucose Monitoring System next week. Considering what I’ve been able to  accomplish since I started using this device, you and it (Dexcom)  deserve more than this little blurb accompanied by a fancy-schmansy  photo.

Enjoy the weekend.

Edit: Turns out this is Day 14. Not 11. I take back almost all the semi-negative things I said about this sensor. 14 days = Rockstar status in my book. (But I’m still chaning it out tonight)

  1. HAHA to be honest, I stop after 4 or 5 days because by then my skin is usually hating on Dexcom and it’s stickyness and itching all to heck. And then I go 3 days without to even things out. So I don’t blame you for thinking it’s time to go. I usually do long before 11 days.


  2. Thanks for the post! I’ve had a Dexcom for almost 2 months and I’ve been trying to figure out how long to stretch them too. I was having lots of tape issues that kept me from stretching the 7 days at all, but I’ve gotten some new tape that seems to be helping. But on day 10 or so of this sensor, I started getting lots of periods where it wasn’t reading at all. The 3 question marks!! And I have no clue how to interpret those, so I eventually gave up and took it out. Glad I did, cause the site was pretty red and irritated. Good luck — not an easy thing to figure out.
