I was really surprised when I downloaded my Dexcom G4 this morning. There was a space of approximately 2 hours where the receiver registered "LOW". I have used the previous generation Dexcom and also just got the Gen4 in Nov. 2012.
I tested my bg before going to bed and it was 125 with 0.3 units of insulin on board. I also have a serious hearing impairment so I obviously did not hear the 'alerts'. Does anyone have suggestions about how I can manage this problem?
