Sensor Snapping by the Seashore

Sensor snapping by the seashore…try saying that five times fast.

The past several weeks have been so busy that I completely forgot about an incident that occurred when I was away on vacation in July.

An incident that I’d never experienced in my decade of using Dexcom CGMs…

It was the second-to-last day of my trip. I was blissfully soaking up the sun’s rays – it was by far the best beach day of my entire week in Maine. That meant that the sun was strong that day…so strong that I was basically applying sunscreen every hour, on the hour, because I am as pale as Casper the friendly ghost.

During one of my sunscreen applications, I noticed that the Dexcom sensor on the back of my arm was looking a little off. I mean that literally – the transmitter seemed like it was jutting out at a weird angle. Upon further inspection, I realized that the grayish-purple prong that helps keep the transmitter in place was hanging on by a thread. I was pretty surprised to make that discovery, for a few reasons: 1) I didn’t know that could happen, 2) the sensor was only about 24 hours old and nothing went awry during the application process, and 3) I couldn’t remember bumping into anything that would’ve caused a plastic piece to break off my sensor. But the most surprising part was that it was enough to cause my sensor to stop collecting readings altogether – I was getting an error message on my Dexcom app.

My broken sensor prongs and me, sitting on the beach.

I didn’t know what to do other than carefully break the prongs off all the way – they weren’t going to do me any good now – and gingerly press my transmitter down into my sensor for several minutes to see if that did anything…and no dice. I resorted to plan B, which was to wait until I got back to the house I was staying at to do some more research into the matter.

Unfortunately, the internet had nothing helpful to offer me. I was somewhat relieved to know that this has happened to other people, but definitely bummed to learn that there wasn’t a real solution other than to apply a new sensor – which wasn’t an option for me since I had only packed the one sensor for my trip. Whoops. So much for me being the diligent, prepared T1D that I thought I was.

Ultimately, I decided to rip the sensor off and deal with finger stick checks for the rest of my trip; after all, I was going to be returning home the next day. I look at the whole incident as yet another example of why it’s important to pack extras of my extras, and as a reminder to expect the unexpected in life with diabetes!

  1. Dear MollyT1D.

    If you need one, pack two. If you need two, pack four. If you need three, pack six.

    Sincerely,

  2. Oh no! That stinks! Glad you had a backup.

    I *think* I saw somewhere recently that spray-on sunscreen has something in it that can degrade the plastic in the sensors…? Not sure if you were using spray or not (I personally think it is one of the best inventions ever), but that might have had something to do with it.
