My Dexcom sensor just finished its grace period

And they don't want me to put on another till after surgery. This one like to never came off, which I guess is good, because I had trouble when they first came out with the adhesive not holding and had to use third-party overpatches.

I am having an issue at the moment because I have a new phone [it was free with credits through T-mobile, with a lot more storage if you pre-ordered, and it's three steps up from my old one], and it's running the lastest Samsung version of Android UI 8, which hasn't been tested by Dexcom, so it isn't compatible with the application yet, so I can't get my readings through my phone, and since I can't get them through my phone, I can't get them through my watch. I do have a receiver, thankfully.

Anyway, for the next few days, I'll just have to rely on my old meter to tell me how I'm doing, pricking my fingers, and since I couldn't be on Monjauro for a period around the surgery, my sugar levels have been fluctuating more than usual. I'm not used to having to do that anymore.

Don't worry, I'll put another one the first chance I get once I get home from the hospital.

Ah

Woke up to the dulcet tones of my glucose monitor announcing I was having an urgent low (the monitor itself said that; my phone and watch read 39, which is, indeed, pretty freaking low. [Normal's about 80-120 for a diabetic.) Then the sensor went offline, which sometimes happens during the first 24 hours within placement (I am, at least finally doing well with putting it on my arm, and I found an overpatch that actually holds the thing on that I can easily put on myself. Anyway, I ate some Meijer version of Honey Nut Cheerios with banana and rice milk, because that usually makes my blood sugar rise quickly. The sensor came back up and it was 94 within a few minutes. Yay! So glad this woke me up. That's its job, and I'm glad I stuck with it through the learning process (Dexcom sent me no less than nine replacement sensors in the first six months (each lasting 10 days). There were seven that fell off as I couldn't get them on where they stayed. One malfunctioned, probably because I hit a capillary and blood fountained through it (gross), and one I managed to bump into something and tore it right off (ouch). Each time I contacted Dexcom directly, filled out what had happened and they sent another one for free. I'm very grateful for that. There was a learning curve when I started the G6. This was harder. The G7 goes on the arm, not on the abdomen, and I'm fleshier than most of the pictures and diagrams I've seen. But once you get it on, it has more accurate readings, warms up in about 30 minutes rather than 2 hours, and has a 12-hour grace period of readings after the sensor expires before it stops giving readings. I have also learned that if you use both the Dexcom and a smartphone (and by extension a watch, which is connected to the phone), pair the phone first, not the receiver, as it takes almost the entire warmup time to pair to the phone if you don't. Anyway, I would really recommend this, just know it's going to take a while to get the hang of it.

I am a bit frustrated

I sent the following e-mail to Dexcom regarding my latest problem with their G7 continuous glucose monitor system that I have been trying to use for three months now. I'd already put a service ticket in; this was supplemental.  Let me preface that each time they have sent me a replacement sensor at no cost, and their customer service has been excellent over the years.  Maybe it's my skin. I don't know.  But I hope they can solve my problem.

I just wanted to let you know this seems to have been an actual sensor failure. It was inserted, paired, warmed up, and was stuck well on my skin, but it failed after two readings, about 15 minutes after the warmup was complete.  However, I did notice when I took it off that I'd apparently hit a capillary or something, as there was quite a bit of blood under the sensor.  This has happened one other time (it actually fountained through the little hole, but that one remained working). This is, I believe, the fifth sensor I have had to contact you about.  I'm having difficulty keeping them on even with the over-patches (and larger third-party bandage over-patches on top of that, even).  I use a skin-tac pad prior to inserting and keep the liquid form with me in case the over-patch begins to peel. I am showering less so I don't have issues. I have just joined the YMCA because of the warm water/therapy pool but have been afraid to get in it because these things refuse to stay on my skin. This has all been within my first three-month supply. I have tried four different types of over-patches in addition to just your own.  I initially had trouble with the G6 but nothing like this.  Is there anything else I can do? I have read all the FAQs and watched numerous Dexcom and YouTube videos. I'm really frustrated. I have had exactly one do what it is supposed to do as far as sticking/working.  I like the G7. I like the arm (although I did better on insertion by looking online for pictures of people my size wearing it; the diagrams are a little misleading if you have any flabby skin).  I like the shorter warmup and the grace period, and I believe the readings are more accurate.  But every time I change my sensor it's very frustrating. Most of the ones which have fallen off have done so within a couple of hours.  One made it to the next day and had to have the skin-tac liquid applied.  As I said, only one did well, and that was with a third-party over-patch. I am using my left arm, which is not dominant. The one time I tried the other it fell off immediately. I cannot begin to tell you how much frustration and anxiety this is producing.  I just want it to work. This one really looked like it was going to stay on well and then within a few minutes gave up the ghost. Any help you can give would be appreciated.
