Remember that one time I had a bloody Dexcom sensor? I was worried that it would affect the accuracy of the readings, but it seemed to be just as “spot-on” as the typical Dexcom sensor. It may have affected the life of the sensor, as I got about 9 days of readings as opposed to *ahem* slightly more days.
(this is especially not medical advice) Occasionally towards the end of a sensor’s life I will get the dreaded ??? after the sensor has been exposed to water (e.g. shower, pool). I can carefully pop out the gray transmitter, dry off the back of it, dry off the sensor base, pop it back in, and get a few more days of sensor readings. So a few days ago when I saw the question marks I thought I’d try this technique.
Unfortunately, instead of springing back to life I could feel the sensor wire slide out of my skin and into my hand. And that is when I knew that sensor was done.
I was a little surprised by the look of my skin once I took the adhesive off. There wasn’t really any blood around the insertion site, but I feel like I have a better understanding of the capillaries in the surrounding area.
New sensor inserted just a few minutes after that, which was probably a very good idea as I continued to fight a battle with overnight lows. Looks like it’s time to review those nighttime basal rates again.
