Making it easier to stay on top of frequent G7 replacements
I’ve been on the G7 15-day for 3 months now, and every single sensor failed before it hit 15 days. As you all know, you need to request replacements right away and hope that they ship quickly, because insurance will leave you hanging when you hit the end of your normal supply too soon.
Dexcom’s online form makes it easy to request a replacement, and so far they’ve replaced each failed sensor for me. But I’m usually busy traveling or working and sometimes can't order a replacement quickly.
Why this is hard...
- You need the Sensor ID, and the start/fail dates when you request. The Dexcom app doesn't clearly show that info in your history, especially if you’re already days into a new sensor.
- I’ve often misplaced or thrown away the physical applicator by the time the device fails 7-10 days later. This is especially hard when I’m on the road and don’t have access to the old applicator.
- I’ve tried writing down the info, and taking pictures of my applicators, but being so busy and forgetful, I couldn’t stay in the habit.
Here’s the workflow I use to make this super easy for myself:
- Export: Anytime a sensor fails, go into Clarity and export your sensor data.
- Get the info: Upload the exported file into Claude and tell it to identify the Sensor ID, start date, and fail date by looking for the last moment when your device changed.
- Request: Immediately fill out a replacement form through the Dexcom app, copying in the required info.
- Track: Dexcom emails you a confirmation. If you connect Claude to your email, you can then ask it to read your email and pull in the Dexcom case number, and later, the FedEx tracking number after it ships.
- Confirm: You can tell Claude when that sensor arrives so it can mark it as “received” in your table.
- Repeat the process on the next failure.
I keep an active chat with Claude so I can track it over time. If you ever forget to send one in for a few weeks or longer, this will help you figure out which ones are still outstanding for you to request.
This is what the table looks like. So far I’ve had to request 7 replacements. This would have been a REAL pain to manage without a system like this to keep me organized. It’s also interesting to see the real data about how long the sensors are lasting (9 days on average for me).
There could be ways to automate this even further — having to export your log from Clarity still takes a few minutes. But for the low level of effort, it’s saved me a lot of headaches. You should be able to do this with the free version of Claude. You can also ask it to show exactly the data or style you want to fit it to your own needs.
Hope this is helpful to someone else. I’m curious if you all have your own systems to manage recurring failures. Please share how you’re keeping up with it!
Cheers!
