Repeated Dexcom G6 failures


Yes, a physical change like this would definitely require a trip to the FDA, maybe not a new trial but it would need to be submitted. More likely is they made a manufacturing change that decreased their manufacturing costs and still allowed the sensors to perform for their warrantied time frame. It may have just had the side effect of the sensors not lasting 21+ days as they used to for us.

I base my supposition on a sudden change last year in the performance of the G5 that continued through multiple batch numbers and included observations from a number of people that I trust.


No. It’s not a total. Every time you have a failure, call them and they will replace it free of charge. You may have to wait on hold for a while, but just turn on speaker phone and wait for someone to answer.
