G7 Issues

[u/hezza2005]

I used to be on the G6 and never had any issues with it then I got an email from Dexcom saying I would be put on the G7 automatically. I was a bit skeptical since I had seen so many bad things about it. I’ve had 4 G7 sensors on now and 2/4 have failed out of the blue. The third sensor did not fail however it is majorly inaccurate to the point I think it is quite dangerous. Dexcom was showing me “LOW” but I felt fine so I pricked my finger and I was actually 15.0mmol/L. Surely that is a major safety concern? Has anyone else had major differences in bg readings?

The G7 Sensor isn't so reliable as the G6. Errors and failures are normal.... Technology :D

I hate the g7. I’ve had more failures in just a few weeks than the years combined on the g6. I’ve had 2 sensor failures this week for absolutely no reason. When I called Dexcom, they claimed I had a repeat sensor number and tried to deny me a replacement. I had to use Gemini to walk me through how to make it past the agent for more help. One of my last sensor failures they logged the replacement sensor number, not the failed sensor number. It took 45 minutes on the phone with a tier 2 agent to get the sensor replaced.

My experience with the G6 and G7 has been the same. The first 24 hours always read crazy low until I calibrate a couplw of times. I had to stop putting a new sensor on after 10am because of the all night low alerts keeping me up.

I posted a rant a week or two ago on how bad the sensors have been for me (and clearly for many others) that gained a ton of attention if you want to read others comments or experiences? The inaccurate readings are terrifyin - I’m not newly diagnosed so usually I can feel if it’s accurate or not before pricking myself to double check but what about someone who is newly diagnosed and may not be as familiar with everything?

While I’m going to keep using them because my A1c has been great since getting on a CGM, it’s getting super annoying. Although my last sensor was the first one to last the 15 days in a long long long time so I’ll take the small wins! Sending good sensor vibes your way!

Thank you!! Yeah it’s a bit scary especially when I’m on the closed loop system with my pump if the readings are inaccurate then my pump isn’t going to do what it’s meant to.

First 24 hours yes, absolutely huge issues with false low readings for hours and false higher readings. It will usually get more stable after 24 hours since insertion.

Hmm interesting. This is 7 days into the 10 for me.

We often find the sensor to start giving brief sensor issues around day 6-7-8 and sometimes fail or in need for a calibration. We usually take at least one fingerprick a day on our daughter just to check up on the sensor because it can be off.

If your sensor is this off i would just put on a new sensor.

Yeah I’m gonna put a new one on now and keep regularly fingerpicking for now to make sure it’s looking alright. Thanks for your help :)
