Here’s the original TUD thread:

> [@FDA Warning Letter to Dexcom posted March 4](https://forum.fudiabetes.org/t/fda-warning-letter-to-dexcom-posted-march-4/15197):
>
> The FDA has posted [their warning letter to Dexcom of March 4](https://www.fda.gov/inspections-compliance-enforcement-and-criminal-investigations/warning-letters/dexcom-inc-700835-03042025) on quality control issues with G6 and G7 sensors. It reveals some of the technical issues with verifying the accuracy of the sensors. There are no issues concerning sanitary conditions or other things relevant to users. This letter had been mentioned in another thread as possibly contributing to the current shortage of G7 sensors in the US market.

That lacks the sensationalism so I guess no one noticed. Nothing like a picture of a coffin to sell a story. I give the guys credit for having found the letter:

> **[Dexcom FDA Inspection Records Obtained via FOIA by Hunterbrook](https://www.documentcloud.org/documents/26102809-dexcom-fda-inspection-records-obtained-via-foia-by-hunterbrook/)**

Maybe they read @Randy’s post. They certainly include the link to the warning letter from that post, though I guess it probably came from some other news outlet.

EDIT: they also paraphrased @bkh ‘s analysis of the sensor coating issue, picking up on the accuracy issues and, well, amplifying them.

**News** _old news_, “Hear all about it.” Diabetics dying, **dead** because they use CGMs.

My wife, who does the stock stuff, noticed the story last night (she does stock 24x7), sent me a link this morning. I’m pretty sure sensationalist articles like this will never help us. I’m pretty sure they will kill us, maybe;

> CGMs have been banned by the administration because of dangers to diabetics using unproved and frequently unregulated technology.
