I Switched to Dexcom G7 for Accuracy but Got Dangerous False Lows Instead

We switched to the Dexcom G7 because of frequent measurement errors with the Freestyle system, hoping for more reliable readings. But what we got was even worse. Dexcom G7 showed a critical low alert, which immediately sent us into panic mode. While rushing to treat what we thought was a severe low, we decided to double-check with a fingerstick—and it showed 317. That’s not just a mistake—it’s dangerous misinformation that could lead to unnecessary and harmful intervention.

The rest of the day was spent battling with the sensor, constantly trying to calibrate it, hoping it would correct itself. I’m honestly exhausted. We rely on this device to manage our child’s condition safely, but it’s turning into a source of stress and fear instead.

Dexcom, this kind of error is unacceptable, especially when people’s lives are on the line. We switched to your product for accuracy and peace of mind. Instead, we got anxiety and false alarms. You need to address these faulty readings urgently and improve the product’s reliability.
