I am a type 1 diabetic, (b)(6) years old, 52 years as a diabetic.I am a tandem pump user and a dexcom cgm user.With both devices linked electronically.For the past 7 days, i have had problems with the dexcom sensor device and the transmitter.Both the transmitter and the sensor failed --- one invalid transmitter device error, one invalid data error and two sensor errors.This is not the first time this has happened.I've been a dexcom and tandem pump user for the past 10 years, and over the past 18 months, these two device failures have occurred multiple times.Each time they happen, i am forced to monitor my blood sugar proactively / intermittently, unlike having the benefit of 24/7 blood sugar readings with the pump / sensor / transmitter devices linked.The 6.1 a1c result is actually a very good result in terms of a1c.The problems with the device(s) have occurred since then, and have raised my a1c considerably.Fda safety report id # (b)(4).
