I’ve been lucky enough to have the Dexcom G6 CGM in my life for just over six months now. In that time, many people in my life – both T1Ds and non-T1Ds – have asked me countless questions about my experience with the device. I thought it’d make sense to address some of the most commonly asked questions here, in the hopes that I can provide some insight to those who are curious about the Dexcom G6.
Question: Can the Dexcom G6 be restarted?
Answer: In my experience, no. I cannot get the G6 to restart like I could get my G5 to restart. But take my “no” with a grain of salt, here, because I know of other people who HAVE had success restarting their G6 sensor, making its life extend much longer than the 10 days guaranteed by Dexcom. I have only tried to restart the G6 once, with absolutely zero success, following the process outlined here. My advice to those who want to try to restart their G6 is to do so cautiously, and make sure you’re not trying to do so with the last sensor in your stockpile.
Question: Is it actually safe to take acetaminophen (Tylenol) on the Dexcom G6?
Answer: Yes! I’ve noticed that acetaminophen can be taken safely on the G6. I did not anticipate for it to be unsafe, seeing as it was advertised as one of the big improvements Dexcom made from the G5 to the G6. I’ve taken Tylenol a handful of times without noticing any issues with my CGM readings, but as always, be sure to monitor your blood sugar carefully and perform a manual finger stick check if your symptoms don’t match up with your CGM.
Question: I can’t get my Dexcom G6 sensor to stay put for the full ten days. How do you make it last?
Answer: There’s tons of ways you can help ensure your G6 sensor stays stuck on for the entire ten-day duration. I always make sure that my skin is completely dry before the sensor makes any contact with the site. Avoiding any excess moisture is key in helping it stay put. If I notice the sensor starting to peel around the edges after a few days of wear, then I use a Pump Peelz CGM adhesive to keep it in place. Those tend to work really well for me. In times of serious adhesive doubt, I also use Skin Tac wipes, which basically glue that sucker down. One last tip I recommend is to avoid sites that come into contact with a wide variety of surfaces. In other words, a sensor that’s placed on the abdomen may fare better than a sensor on the leg, because the odds of the sensor getting accidentally knocked off due to contact with clothing or other objects are lesser. You know your own body better than anyone, though, so trust your own judgment when it comes to CGM placement.
Question: Is sensor insertion truly painless?
Answer: For me, G6 insertion has been pain-free approximately 85% of the time. It’s stung slightly a handful of times, but I’ve found that it only hurts when I choose a site that’s not particularly fatty. That’s why I generally stick with my abdomen – either side of my navel – or the back of my arms for G6 insertion.
Question: Is the G6 really that much more accurate compared to the G5, or any other CGM on the market?
Answer: Yes and no. That may not be a very satisfactory answer, but I’ll explain why that’s my belief. Overall, the G6 seems to be more accurate for me than the previous Dexcom CGM models I’ve worn. Are the number always on point compared to what appears on my meter? No. Do I wear the Dexcom CGM to have an accurate picture of what my exact number is at a given moment in time? Kind of, but I also know that this isn’t totally realistic. After all, users of the Dexcom CGMs know that it measures blood sugar levels in five-minute intervals. It can’t give me a clearer picture of what my blood sugar changes are minute-to-minute. So with that in mind, I find that the G6 is really excellent for monitoring trends – seeing how rapidly my blood sugar is falling or rising, or seeing how it changes gradually over time. The patterns are more important to me than the precise numbers; at least, that’s how I feel in my current stage of diabetes management.
I can’t really speak to other CGMs on the market, such as the Freestyle Libre or Medtronic’s CGM. But what I can say is that I’ve heard less-than-stellar reviews about both. It’s important to remember, though, that they’re not meant to be the exact same as the Dexcom CGM. The Libre itself isn’t really continuous and can’t provide users with information until they chose to wave the receiver over the sensor. And as far as I’m aware, the Medtronic CGM communicates directly with Medtronic pumps, and I’m not sure how seamlessly the systems work together.
Bear in mind that when it all comes down to it, I’m answering these questions with my experience, and my experience alone, in mind. Dexcom is and will always be the number one resource to go to with any questions regarding their CGM devices. But hopefully, the information I’ve shared here will at least help someone who is curious about the G6 feel more motivated to seek additional information. I stand by the fact that it has revolutionized my own diabetes care and management, and though it’s far from being flawless, it’s still an invaluable tool to have incorporated into my daily routine.
