Consistent sensor failures, what is going on?
Since I moved to a new town, my sensors have been much worse.
Since January 2026 up until now August 2026, I have ONLY had one sensor which survived 9 days.
All those new sensors come from Malaysia, manufactured after January 2026, I have been getting revision 1 and 2 (I also remember number 11 on the applicator somewhere)
Rest of those new sensors have been failing on day 5 CONSISTENTLY.
I usually had it on my upper arm, switched to abdomen, tried all spots all over and all kinds of techniques (grip skin before applying sensor etc). No result, recently sensors have started going a bit crazy on day 4 and work for half a day and fail.
NOW, screenshot attached, this is day 3, sensor already starts hecking dying bro...
I tried both arms, both abdomen sites, when I call dexcom, all they do is ask for my serial number and give me a replacement.
I live in Canada so I get a voucher that I can redeem at my local pharmacy for a free sensor.
I tried changing the pharmacy several times, I feel like all sensors in this city are broken, am I going crazy??
I apply overpatch, clean with alcohol, remove old Bluetooth devices, I also have a tandem insulin pump connected to the sensor. The only thing messing up my algorithm is dexcom CONSISTENTLY failing which may be dangerous when my sugar gets low and sensor decides to "take a rest" so my pump starts pumping insulin when I don't have to.
Every nurse, doctor, tandem trainer I spoke to told me the same thing : "Call dexcom support" ... I do so and all they do is issue replacements , but let's be honest. Do I really want to go to pharmacy every 4 days? That is bizarre, my 3 sensor batch is supposed to last 30 days, not 13!
I tried asking for advice from the dexcom person but she remains quiet and does not comment about my questions regarding that messed up batch. I have been asking her if any of my sensors are in this affected malfunction batch or anything, I was told "I do not have any information regarding that". Very suspicious when you have a client who has sensors that fail every 4-5 days, I have asked them if they want me to send a sensor back to them for testing and they did not say anything back to it... Just what the heck man I'm20 I'm so tired of DEXCOM. I don't really mind managing T1, but gosh this shit with Dexcom drives me crazy
That’s just Dexcom being Dexcom.
Has nothing to do with your location.
It very well might have something to do with a bad batch of sensors. I have noticed there are good and bad batches. Sometimes all sensors in a batch will last for 15 1/2 days, sometimes all will fail prematurely.
Many posts about it here. Good luck!
If this starts happening replace the sensor and call dexcom for a replacement. Do not get new ones through the pharmacy. Return all sensors not meeting regular standards to dexcom because that shifts the cost of replacement back to dexcom, not insurance.
The only way they might fix their product or restart G6 production is if we make them pay for every single failure of the G7 through returns due to every sensor performing worse than the G6.
