      Since starting on a CGM, has your healthcare provider’s frequency of ordering A1C testing changed?
      T1D comes with more than its fair share of dystopian grace notes. However, the indefatigable frequency of A1c testing seems to go on forever. I started with the Medtronic CGM dubbed "The Harpoon" in 2006. Tests and frequencies have not changed an inch in 20 years. (¬////¬)

      Do you use your CGM data to help make adjustments in your diabetes management plan?
      Often? Try Always! I only see my doc 1x a year to legally fill Rx. Otherwise I manage 100% on my own and make all my own dosing adjustments.

      My pump and I use the data to make adjustments at every meal, and even during the day, e.g. corrections. But I also use the data to track longer term trends and usage so that I can make adjustments to my pump regimen, bolus rates, correction rates, basal rates etc.

      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!

      Methinks the question doth another answer require. I almost clicked "out of range," but the occurrences often happen when withing 6 feet of CGM and the *#($% thing still has a signal loss. I re-orient so both devices are face to face. It STILL indicates signal loss. Then, after considerable time, these digital devices change their minds and say to each other, "OK, let's communicate again." My patience and frustration are suffering. 🗣˙◠˙

      Not only do I rarely change my G6 sensor before the 10 days, I usually wear them 15 days thanks to my Anubis transmitter.

        I sometimes bleed a lot. Enough that I wait to see if there’s blood before adding the transmitter. If there is I dab it up with alcohol wipes until it stops, then add transmitter. Except for one time, the sensors still worked fine. Once I had to change it after a couple of days.

      I selected Twice, but that was with the FreeStyle Libre 2 sensors. I’ve now been back on the Medtronic Guardian Sensor 3 sensors and that has lasted a full 7 days. (I’m due to get an upgrade to the Medtronic 780G on Wednesday, and that requires an upgrade, too, to the Guardian Sensor 4 sensors.)

      My Dexcom G6 almost always starts giving wonky numbers on day 8 of 10. Ironically, today is day 8 and it’s currently giving me a number without an arrow after displaying “sensor error” for the past half hour…sigh…but it works so well the rest of it the time that I continue to use it.

      Never for me, but it is interesting to see postings on FB T1D and Dexcom related groups how many have repeated issues. If the training and understanding of the device and technology was provided, I wonder how many more “never” experiences tgere would be.

      I use FreeStyle Libre 2 and there has been a time or two when I’ve had to change it twice in less than 24 hrs. It could have been how I inserted the sensor. IDK.

      On the last day with G6, I sometimes get brief periods of “sensor error”. Not enough to make me change it early, don’t have a spare one with me at work anyway. I do keep finger stick supplies at work, so I have back up.

        when my G6 seems quirkey, I finger stick.. Sometimes they are close and some they are a little off or a LOT !!! I dont see how you can link the CGM with a Pump and feel safe !!!

      My sensors nearly always last for 10 days. Last month, it turned out to be my Tandem pump that had stopped receiving the signal. After some trouble-shooting with replacement sensors, I ended up with a replacement pump (1 month before the end of my 5-year pump warranty.)

      I bleed a lot and can’t get a fresh sensor to calibrate. My PA suggested putting ice at the sensor site and that seams to help. Only once this month for this reason.

      The latest libre, libre 2, has occasionally given me issues within a few hours of deploying a new one. Once it is on, it lasts the full 14 days ubless I manually interfere with it. In my experience, there are never problems with bleeding or discomfort.

      Things continue to work pretty well. I find that the main complaint I have is how much anxiety there seems to be concerning getting supplies on time, and not getting the full ten days with a sensor. Worry wart, yes, but I think it’s the price we pay to be relying on technology instead of pancreases!

      The majority of the time there are no issues, but during this month, after replacing the transmitter I had two sensors needing replacement after the first twenty minutes. After the first sensor failure notice I called Dexcom and requested a replacement. I had already put in another sensor. While speaking with the Dexcom tech the second sensor failed. I was very upset and definitely let the tech know how much! He asked me what ID number I had used for the new transmitter. I told him the number that was stamped on the bottom of the transmitter. Then I learned that the transmitter I thought was new was “reconditioned”. I needed to use the number that was stamped on the transmitter box, which was a different number. When I used that number in the pump for the transmitter, the sensor suddenly worked. I had one sensor left, so was very glad to have the inserted sensor working, BUT why was I charged full price for a reconditioned transmitter? No answer from the Dexcom tech. My last question to him was how long would this reconditioned transmitter last. He said it was guaranteed for 90 days from insertion. So beware! Dexcom is sending reconditioned as new.

      With my Medtronic sensor I have had to recharge the transmitter before the 7 days was up, but now have a new transmitter which is lasting 7 days. As to the sensor, I have used one for 14 days by recharging the transmitter at day 7.

      When you are on Medicare Part “B”, you get your supplies on a fixed schedule. Medicare will allow you to get your prescription filled 5 days early. If the DEX sensor fails once/twice a month you lose time and may not be able to get your sensors early. Everything depends on your supplier.

      I rarely get the full 10 days. I said 3 because I changed every sensor this month early. But, technically, it was 4 but the 4th one was due to a transmitter issue and likely “user error”.
      I think it’s because I bleed a lot… sometimes get massive bruises under the sensor. I’ve tried everything under the sun to get them to last longer, but nothing seems to work for me so that’s why I think it’s a bleeding issue.

      I frequently get less than 10 days from a sensor. Dexcom said to use an overpatch to secure it now. I now put on an overpatch when I put on a new sensor and that has helped a lot.

      I haven’t had any problems in the last month with my Dexcom.
      This happens maybe twice a year with a nice replacement from the company, but usually less than 24 hours before expiration.
      I think I have made more of an effort to stay hydrated in the past year which helps.

      In the 11 years I used MEDTRONIC cgm (generation 1,2 &3) I rarely got all 7 days. In the past 2 years on dexcom I have reliably gone all 10 days every time.

      This past month I’ve not had any sensor need replaced prior to Day 9 out of 10. I ripped one of my arm on Day 9 so it didn’t count for this question.
