      Do you use your CGM data to help make adjustments in your diabetes management plan?
      Yes. Isn't that one of the reasons we have CGM data? Almost all of my adjustments are from my CGM data. And, I make most of the adjustments.

      If you use a CGM, is it accurate on day 1?
      It takes a few hours to get close.

      How often do you adjust a planned physical activity because of how your glucose is trending?
      If I am above 150mg/dl don't need to carb up. If I am around 100mg/dl I definitely need to carb up. Aren't we always evaluating where we are and anticipating where we might land. That is part of active management.

      For me it's compression lows - and that's it. I see that most complaints are about connection to phones. I don't (won't) use my phone. I have to have a work phone with me at least 60 hours a week, and I'm not interested in carrying (or wearing) two phones. I rarely lose connection between my Tandem X2 pump and the sensor/transmitter. Sometimes I will walk away while it's charging and take myself out of range, but that's on me.

      1 and 2 days before its about to expire. It goes out of range several times those days. They should prescribe a 10 day CGM for every 8 days because on average, that is the use it seems we get.. and if you call to report it, you lose an hour on the phone!

      This should have been a multiple choice question. It happens every time when I go to bed. I have to force stop the T:slim app and restart it. It happens when my phone is on the night stand 2 feet from my G7 sensor and pump. It happens when I shower. It happens if I move my pump to the other side of my body. It happens when I leave my phone on the table and walk across the kitchen. Then there are undetermined times it drops. So my conclusion is, this interface is not robust enough for users. I have complained to Tandem many times and they came up with forced stopping the app. This is my biggest disappointment with this pump.

      Other. Censors cement themselves like a tarantula spider and have never fallen off (in 16 years!). Dozens of other things go wrong with transmitter, pump signals, sensor itself. c’est la vie ¯\_( ͡❛ ͜ʖ ͡❛)_/¯

      If they fail, I call. I have already accidentally caught one and ripped it off – in this case, I did not call because it was my fault, not the sensor adhesive’s fault.

      So far, I have not had one fall completely off. I use their overlays with strips of Opsite Flexifit on either side. If it gets raggedy, I trim and replace the Opsite Flexifit.
      When a sensor has occasionally quit early, Dexcom has always replaced it.

      Mine don’t fall off, but often quit being accurate on about day 8. I’m thankful for my BGM at those times and often stop a session when that happens. Dexcom is always good to replace a sensor when not working correctly.

      Medtronic now has an online form so they will replace up to 3 sensors every 90 days without needing to call. I’ve only had sensors come off in the summer when I have been swimming and sweating a lot. OR I get it caught on a door frame. Since I started using SkinTac a few years back I haven’t had any issues.

      I wore a Dexcom CGM on my thigh during my C-section (several years ago) and the surgical team ripped it off by mistake and I had them retrieve the transmitter from the garbage. I did not call to have the sensor replaced because generally Dexcom sensors could be extended more than 7 days and I usually had enough to last me through 90 days insurance coverage.

      I said “sometimes”, but really it should be “almost always.” I have had cases where I had one day, or less on my sensor, and just didn’t bother calling Dexcom. I don’t have the time to waste answering all of their questions. Dexcom just goes on-and-on with questions, and I have a life to live. I can’t spend that kind of time on the phone. So, if my sensor is near it’s expiration, it is not worth the time to call them.

      Dexcom is very easy about replacement. I think there’s a limit over a certain time period. But I’ve never run into it. They’ll also replace if you’ve got a bad insertion where the filament is causing discomfort. And they’ll also replace when the sensor gets yanked off from removing clothing etc. so it’s not just about adhesive giving way before the 10 day period.

      OTHER: I’ve used the Dexcom G6 for more than two years and not one has “fallen off” prior to ten days. Yes, I lead an active outdoor life year round in Florida and sweat profusely when biking and working the farm, and I don’t need a “sticky” prep on my skin.

      The “secret” [CLEARLY STATED IN DEXCOM LITERATURE] is to properly prepare the skin site by washing with water [no alcohol mentioned] and ABRADING the skin sufficiently – to remove a couple of dead and failing dermis layers.

      I use the stickers over top of the CGM so they don’t fall out anymore. However, on more then one occasion, the transmitter has expired a day or two after I put a new sensor in. I need to call for replacements more often

      Because of the “rationing” of DME by Medicare, I’ve always called Tandem/Dexcom when a sensor hasn’t lasted the full 10 days. Although, my Dex has Never “fallen off”, but has needed to be replaced early due to lost readings exceeding 3 hours total.
      Dexcom has been great about replacing them, providing I meet the replacement criteria. I go to the T:connect reports to tally the total sensor “down” time for any sensor before I call for a replacement. It can be found in the “logbook” feature of the reports. On those few occasions when the adhesive appears to be failing before the ten days, I simply add either an overpatch or other tape to secure it for the duration. Luckily, I haven’t experienced many adhesion issues, even though I live in hot, humid Florida. (Favorable body chemistry, I think!)

      I’ve never had my CGM fall off before it expired.

      I did have two that never got started successfully. One of those never released from the injector (everything, sensor and the injector stayed stuck in me) and the other one wouldn’t connect with the transmitter. In both cases Dexcom sent me replacements quickly.

      I’ve never had one fall off on its own, but Dexcom has been great about replacing them if I lose one for any reason, including removing it myself before an MRI. I usually use the online form to request a replacement rather than call.

      Because of insurance, I can run short if I lose days on my sensor so it is very important to make sure I am covered for the lost days. It is also good to have some extra days as I live in rural Alaska part of the year. It has been a long time since I have had to replace a sensor tho. Very long time.

      I call sometimes. My G6 sensors often die on day 8 or 9. So I call at every 3-4 sensors to recover my lost days. I pay cash and I am on the Dexcom subscription program. I just have to make it to the next scheduled delivery.

      I can sweat off sensors. The Abbott ones I learned a wrap of 3M Corban would keep them in place. I haven’t found a practical solution to keeping Dexcom sensors on when the adhesive lets go.

      There are many comments about insurance and medicare limiting access to supplies. In my experience Dexcom’ s push to bill for sensors “per day” is the root of this problem. It has allowed them to ratchet up the price to 5x what Abbott is charging at retail so I can’t afford to buy a replacement.

      Abbott has their own problems with software bugs they refuse to fix that will blacklist a sensor.

      So of course I contact the manufacturer to replace every sensor. In the US every prescribing doctor should have to tell patients contact the company to get replacements.

      I answered ‘other’ because I’ve never had the sensor just ‘fall off’ — it stays on until I pull it off. They have sent replacements (Dexcom G5 and now G6) when the sensor has failed for other reasons (bleeding for example) and the tech person on the phone has told me to pull it off and replace it.

      Mine haven’t fallen off. One time it did become loose so I just reinforced with medical tape. If one fell off, especially if I did nothing to cause that to happen, I would probably call since I do call for other types of failures.

      I said sometimes. Because if I knocked if off I feel responsible for the failure. However Medicare has zero wiggle room for needing your supplies earlier than they allow, so it does not hurt to ask Dexcom. They have never turned me down or made me feel bad for calling. They always apologize and begin asking their required protocol questions and move through the replacement process. I once purchased emergency sensors from Amazon when I needed extra from travel because they provide so much peace of mind. Height of Covid delays… Expensive.

      I said, “Yes, always,” because it has and I did once or twice. This rarely happens though.

      In over 3 years of using Dexcom CGM I have not yet had a sensor fall off. I am grateful!

    If your CGM sensor falls off before your session is supposed to end, do you call their customer service for a replacement sensor? Cancel reply
