A few weeks ago, I was all set to order a CGM (Dex) for my son. Had done research, talked to his endo, got the brochure and papers to start the process, and was ready to go. My son has even asked for a CGM, and there is so much enthusiasm on this forum from those who use CGMs. Now...I'm nervous. My FIL being very ill in the hospital caused me to forget the CGM for a while and, now that I've come back to thinking about it again...I'm remembering recent posts about the Dex not always working reliably at night or even during the day. I guess I was naive to think we would be getting a device that was as reliable as the pump...sounds like CGMs can be hit or miss sometimes. I'm also leery about putting the sensor site in my son's tummy. He has ZERO fat there...and pump sites in his tummy have had nothing but problems...we only use his butt now. If I need to pinch anything to get a sensor site in...I won't be able to...I can barely pinch skin on him there. Can some of you share your feelings about the reliability of CGMs...particularly the Dex?? How often are you getting ???s or whatever the message is for it not working? If I'm going to be poking my son yet again, I really want it to be for something that works most of the time...especially at night.
