Dexcom G7 inserter above, front and back
You know I’m not in love with the G7. But I did discover one thing that I quite like – you can start a new sensor while the current one is on its last 12 hours. That gives the new sensor 12 hours to get used to your body since sensors activate as soon as you insert them. Since my first 24 hours on a new sensor are mostly inaccurate, most of the time, this is an advantage.
But a word to the wise: When you put on that new sensor don’t throw away the inserter! As I did! Yesterday! And then took the garbage out! Immediately!
Because this morning, when I went to switch over to the new sensor, it asked me for the sensor code. That’s the 4 digits on the back of the sensor, pictured above on the right. It’s not on the box, I can attest to that having examined it multiple times.
So, lucky me, at 7:15 this morning the husband did a dumpster dive and retrieved the bag with the precious inserter. Shortly thereafter we were up and running.
Dexcom G7, I love you, I hate you. But this morning I love the husband all the more for his sheer gallantry.
Diabetes Stories 
I complained to my medical supplier that I wanted to switch back to the G6 and they told me it wouldn’t be possible. Just received my next 3mo supplies and they did sent the G6. I do have mixed feelings about going backwards though…
I’m seeing my endo Friday and I’m going to ask his opinion of switching to freestyle Libre 3. At tHis point, I’m pretty confident they’re parody products, and the Libre lasts 14 days, is slimmer, smaller and sticks to your body. I’ve already had 2 of these fall off and I hate having to use the patch, it ruins the whole look of it being small.
I have had the same trouble with the overlay patch for the G7. Just crumbles up in my hands. But, I have not had any problems with the G7 falling off without it. Looking forward to hearing your review of the Libre 3. 😉
at the beginning I was having accurate sugar levels on my G7 sensor when I started using it now lately on the last two refills it has been completely out of range. I mean, it gives me wrong readings. My levels are showing high and when I check with my glucose machine, they’re 30 points away from each other so at this point, I don’t know what to do and if I should just switch it to the G sensor six or libre three never tried any of the other two only the G sensor seven any advice from anyone it’d be great thank you
It seems odd two sensors would be so inaccurate. You could try one more. I’ve used dexcom since G5 and did not like the G7 so switched to Libre 3 which is working great for me.
My experience with the Dexcom G7 has been nothing short of a disaster.
I’ve been a Type 1 latent for years, and my glucose values have never been as dangerously high and unstable as since I switched to the G7. This device is a complete step backwards compared to the G6. With the G6, failures were rare . With the G7, I am dealing with catastrophic unreliability: random disconnections, sensors, wildly inaccurate readings.
How is this acceptable for a medical device? How did Health Canada even authorize the release of something this defective onto the market? We are not talking about a fitness gadget – this is supposed to guide life-critical decisions. When it fails, my blood sugars climb unchecked, and the risk is on me, not on Dexcom’s shareholders.
The G7 isn’t just disappointing, it’s a medical hazard. It undermines trust in CGM technology and endangers patients who rely on it daily. At this point, I consider it irresponsible for Dexcom to keep selling it in its current state.
If anyone is considering moving from the G6 to the G7: don’t. Save yourself the frustration, the stress, and the health risks.
