Dexcom G7: Get Ready for the Next Gen

Updated 3-15-22

The Dexcom G6 was a game-changer, as it was the first CGM to end the daily torture of finger pricks. The G6 has only been out for a couple of years, but we’re still anxiously awaiting the release of the G7, which is expected to get FDA approval this year. The G7 just received CE Mark approval in Europe.

How will the G7 be different than the G6?

  • The G7 will be about 60% smaller than the G6 – slimmer, more svelte, and easier to disguise under clothing so you can dig out your skin-tight leather pants and flaunt your spandex bike shorts worry-free.
  • The G7 will have a simplified application and a faster sensor warm-up time. If you’re like me and your sensor often conks out right before bed, you won’t be disconnected from your CGM for as long at an inconvenient time.
  • The transmitter and sensor on the G7 will be combined. It will be a fully disposable unit so you can toss everything at once.
  • Dexcom is currently conducting trials with the G7 on multiple wear locations including the abdomen and upper arm, so those of us who have been wearing the G6 all over our bodies illegally will be able to rejoin the rest of the diabetes rule-following civilized society.
  • The G7 will have a longer wear time (probably around two weeks or so), although the exact number of days is still TBD.
  • There will be a brand-new app experience so we can learn even more about our diabetes management. Sometimes we may not want to know, but it’s there if we need it.
  • Dexcom is working with Lilly and Novo Nordisk on collaborations with their smart insulin pen technology for those on MDI.

What features are sticking around?

  • The G7 will still integrate with Tandem’s CIQ, Omnipod DASH and the Omnipod 5 (also launching later this year). It will most likely also still work in conjunction with DIY Looping.
  • Optional calibrations will still be available.
  • The Bluetooth range will still be 20 feet.

Dexcom CGMs have been used in the type 1 population since their inception, but the technology can have great benefits for people living with type 2 as well. Check with your provider and/or health insurance to see if you are a candidate for CGM. With all  the technology we have on the market and more exciting products like the G7 coming down the pike, there’s truly been no better time to have diabetes.

    Thanks for this info! Are Dexcom/Tandem running any trials with the t:slim+G7? I would love to participate. . .

    If you have any influence with the Dexcom company, can you mention the adhesive reactions (burning, itching,and scarring on the Dexcom G6 so many of us have had since they changed the make-up of it in December 2019? I hope they really test the adhesive on this new G7 before they launch it.

    • They are definitely aware of this issue, and although it affects a minority of people like yourself, I know they are trying to make better adhesives.

      • Thanks for the response. I am hopeful the adhesive on the G7 will no longer be an issue. I also want to mention how you and Dr. Pettus crack me up! You always put a comedic twist on your videos and articles. I look forward to your monthly e-mail. There truly is a lot of funny aspects of diabetes.

        • Thanks Margie!

          I had issues with irritation as well. I tried protective barrier wipes I had used with irritation from adhesive of colostomy bag…reversed years ago thank goodness… it worked perfectly. Just wipe your skin with it where the adhesive part of g6 goes and let dry before you place sensor. It works great. Good luck. That’s exactly what they are called…protective barrier wipes.

      • I am also having major issues with the new adhesive. Severe burn with peeling skin. I recommend the old adhesive formula and include an overlay patch with each sensor…much better 👍

          I have the same problem!

        • Avatar

          I live in Florida and play golf. Needless to say that skin barrier and extra overlays doesn’t always help keep it on. Sometimes I’m lucky to get 5 days out of it

          • Avatar

            Same here! I’m in FL as well. Moved from the west coast, where I didn’t have an issue. Moved to FL and they don’t stick as well if you’re outside everyday. The year round humidity and heat doesn’t help lol

          Hi, I use Not Just a Patch

      • Avatar

        I would not say it’s a “minority” that it affects. I have never met anyone who it doesn’t affect to some degree. There are some challenges associated with strength of adhesive to allowing the skin to breath to stay healthy. Rashes or redness occur in more than 80% of people wearing the patch (in varying degrees). Dexcom and FSL patches both have this issue. They should spend more time and invest in research in this area or partner with BandAid or another expert in that field though as there isn’t one person who like to have little red circles all over their body .

      I have had the same problem with burning itching not wanting to stay on & trying to get sensor out of plastic device to remove.

    • Avatar

      Try spraying Flonase on the area you plan to put your sensor. Spread with alcohol swab and let dry fully before attaching the sensor. If I don’t spray I get super itchy by day 7ish and it is crazy inflamed after I take it off. Be sure to let the Flonase dry completely. Hope this works for you!

      • Avatar

        That’s what I have to do too. My biggest problem with that is….I spray the adhesive to keep my skin from deteriorating, and the damn sensor is less likely to stay stuck!

    My major problem is that many of my dexcom sensors konk out on me before 10 days. I am so hoping that the G7 sensors improve upon that problem. I also don’t actually “start” my sensor till it has been attached for 24 hours as the first 24hrs of data are terribly inaccurate (can be off by 100 points) if I start the sensor during the first 24 hours of being attached to my stomach. I do look forward to a new and hopefully improved sensor.

    • Dexcom is very aware of the current sensor issues people are having, and I also hope the G7 is improved in that regard. But thank goodness we have Dexcom and CGMs in general.

      • Avatar

        Totally agree. I still use and rely on mine regardless of issues.

        I am using a dexcom G6 along with a “in-pen” produced by Companion Medical which Has been sold to Medtronics. I have not heard any comments about using this “in-pen” with the G6.

        I can’t wait for the G7! The G6 has been great but the G7 sounds fabulous.

      Hey Anita- I used to have the same problem with early sensor deaths and, although not approved in adults, have had great luck getting a full 10 days by inserting in the soft area above my butt on my back (sorta like your kidney area). My day 1 accuracy still sucks like it did on my stomach, but getting 10 days on a sensor and not having to deal with dexcom CS to get replacements makes life better 🙂

      • Avatar

        I just started using this area a few weeks ago and it seems to be doing well. I still don’t start my sensor till I have had it on at least 12 hours and that really helps me with those incorrect numbers on the first day. Thanks for your response. 🙂

    I hope the new G7 has an app that will work on ALL modern Android phones. The present choice of phones are a joke and the little receiver monitor does nothing.

    • All of the intricacies that go into connecting with different phones is very complicated, and we need to be more appreciative of what Dexcom has done and not what they have not done.

    • Avatar

      That is the FDA’s fault – every phone that the Dex app works on has to be government-approved as a ‘medical device’.

      Which is why the open source apps (XDrip+ on Android, Spike, etc) don’t have those limits – they aren’t govt approved.

    • I’m on a tandem t:slim insulin pump and cannot use the dexcom monitor due to interference with the pump.

  6. Will the battery in the reader last longer than 48 hours before needing a recharge?

  7. Avatar

    I do hope they will address the adhesive sensitivity issue as well as accurate readings after insertion of a new device.

    • Extremely allergic to Dexcoms adhesive i’ve complained since Dexcom made the change but it was futile! Tried skin prep, flonase, transparent stretching tape and other applications without success.

      • Avatar

        Hopefully the new adhesive for the G7 will work for you, or one of the other new adhesives they are working on in development.

    If this is all true, I am thrilled. I heard on a podcast with the Dexcom CEO that they are sticking with 10 days, but I hope you are right. I’ve also heard that it will take an additional 6 months or so before the G7 integrates with any loop systems. I’ve also heard that DIY loop may not work with the G7. All from people working on it. But I really, really hope you are right about all of this!

    Will G7 be covered by Medicare upon release?

    • I suspect it will be the same coverage for people on three shots per day, but I’m not sure how long it will take to happen.

    For all you dexcom/tandem lovers, is it better than Medtronic? I need to make a decision for my very first pump, and I’m going in circles! Thank you so much for your advice…

    • Avatar

      Dexcom’s CGM is so much better, it’s not even a comparison. I have only been a Medtronic customer since my diagnosis in 2008, but I just stopped using a CGM because all my efforts with theirs through the years were so frustrating. The poor accuracy made it simply pointless to use the Medtronic CGM, which also meant I couldn’t take advantage of the 670 fully. I decided to try Dexcom this year and OMG! I am now in the process of switching to Tandem so that I can have an integrated system, but even just having true real-time data with Dexcom G6 makes it all so much better. You will not regret switching, I am SURE!

      • Avatar

        A new Medtronic CGM will be rolling out in 4-6 weeks, I have been told.

      • I started pumping with Medtronic Paradigm around 2012/2013, so it was all that I knew. Thankfully I have a awesome care team at the University of Washington Diabetes Care Center (shoutout guys) who got me into the trial on the Dexcom G4 and I haven’t looked back since!!
        Type 1diabetes since August 1975, kinda like a kid going back to school and it’s all computers. There’s a group of us on Facebook, Tandem Pumpers Unite and we’re diverse and share info, ideas and hacks that help us all live a better life with this disease!

        Had more than a few ah-ha moments myself, but it’s awesome to find out that I’m not the only person who talks to my pump!

    • Avatar

      Tandem/Dexcom is superior to Medtronic in so many ways. I was on Medtronic with their CGM for a year and switched to Tandem a year ago. The difference is amazing. Sure there are a few annoying things with Tandem, but nothing compares to all the times my MT pump would wake me up just to calibrate. When I switched I went for 7 months without a single finger stick.

    • Avatar

      Tandem. I’ve worn pumps for over 40 yes 40 years. Get the Tandem. I’m on my second Tandem. With its sophisticated features my A1c is 6.1 and I’ve had Type 1 diabetes for 54 years and it’s so wonderful to feel good!

      OmniPod the best pump EVER. PROUD TO REPLACE THE TUBING!! I can be in the pool with OmniPod.

  11. I am extremely disappointed that the G7 DOES NOT give the option to be used with Basil IQ. My Endo and I both agree that the Control is not for me. It has been documented as to why I cannot do G6 placement on the abdomen and have been having it inserted on my arms. I have also found it to me more in range with the arm placement. Due to carpel tunnel, trigger fingers, and facet syndrome in the Cervical Spine I am unable to do placement independently and rely on other type1 friends to do it for me. I so gratefully appreciate this help but but it does get complicate with scheduling. I would much prefer to do it independently rather than imposing on others. I don’t understand why all Type 1 are being forced to go on Control IQ when it may not be in our best interest.

    • No one really knows at the current time about the G7, but there’s no question that once approved, Dexcom will work quickly to have it communicate with the Tandem pump models. And all type 1s are not being forced to go on Control IQ.

      • Avatar

        I certainly hope it allows communication with the tslim when running Basal IQ. I do not want to upgrade to Control IQ. Unfortunately I am old school and can maintain a 5.0-5.3 A1C and being in target range of 65-140 90% of the time as a type 1 on Basal IQ. I know me better than the pump ever will. I hope I can still use Basal IQ with the 7. (crossing fingers)

    • Hi, I don’t know if you will get this message as its so long after the initial conversation but… I thought I would try anyway. I also can’t self-insert my Dexcom so my doctor has written my prescription for weekly changes. This makes it much easier to have someone else help as it can be at the same time every Monday, for example. It makes filling my prescription more challenging, though Byram finally seems to have it set up correctly, but makes life much easier. I’m not sure what your issues are with CIQ? If its just that you went for a while without a sensor this should solve the issue. If it has to do with the settings then its more of a challenge. CIQ tends to allow me to go a bit too low (I have severe gastroparesis) but as long as I don’t overcorrect I’m usually good. At the worst it is still better than a standard pump (no hybrid looping) as it will eventually turn down and off my basal insulin, it just doesn’t do it early enough to prevent needing to eat something. I’m not sure why BIQ would work and CIQ wouldn’t, though manual corrections may still be necessary in addition to automatic ones (I find the algorithm is not aggressive enough if I get at all high, its good below 180 usually though). Anyway, hopefully some of this information is helpful.

    Will there be a smart phone attachment to use when strip- testing to synchronize Dexcom? (Like Dario?)

    The G7 will sync wit the omnipod dash? I am on the regular omnipod and the G6.

    • The Omnipod 5 system is the hybrid closed loop system with Dexcom, so yes it will be integrated.

    Thank you for this information. I really hope they fix the issue of high blood sugars causing the sensor to fail or to have sensor error readings for hours. I have this issue sometimes but I know kids are having this problem all the time.

    Hi, does anyone know when the G7 is expected to be approved by FDA and rolled out to consumers? Initially they expected to release it in late 2020. It has been quite delayed.

    My son started on the Dexcom G5 after 2 years of finger pricks. Life changing! Then it got even better with the G6, which he’s currently using. We hardly have any issues with sensor errors or inaccurate readings unless he’s dehydrated. We can’t wait for the G7! He’s 11 now, so hopefully by his 12th bday in June. That would be a great gift, even though a cure would be even better. Thankful & grateful for these tools!

    Hello @ all,

    this anybody can help me please:

    how long is the wearing time on the arm? also about 10 days????

    And Is there also a receiver like the G6 or only with a app???

    Best greetz from Germany


    • I would be surprised if it did not have a receiver in addition to the app since not everybody is smart phone savvy. I suspect the wear time will be 10 days also, but they have not revealed the official wear time yet. Danke!

  18. Avatar

    Technologically all the further improvements sound great, of course, but I worry that the disposable pile from each sensor+transmitter combo will be even larger than the current shameful amount we have to throw out with each change. I know this is not something you (TCOYD) can address, but I feel that Dexcom should be aware. More often than not, I try to extend the life of my G6s is to minimize the waste rather than for any other reason…

    • Avatar

      It’s always good to be environmentally conscious and do what we can, and every little bit helps. 🙂

    • Avatar

      I completely agree. I was very dismayed to see the size of the disposable inserter for the G6. I realize that having a single use device probably decreases the chances of incorrect insertion, but I would have hoped for something reusable. I hope that with a totally disposable sensor and transmitter, dexcom will at least consider a reusable insertion device.

    I have had type one diabetes since for the last 29 years and it surely has come a long way. I remember the days of mixing R and NPH. Great info Doc!

  20. I’m awaiting my Dexcom g6. I e been reading about the adhesive issues as I am super sensitive to all adhesives pretty much. Currently using the Medtronic guardian, which I hate, and I have to tape it down with hypafix tape. Have seen some good feedback on how to tackle that situation.

    So if I get the g6, when the g7 comes out, will I automatically get that or will I be stuck with the older model. I’m also going to be switching to the Tandem.

    Thank you!

  21. I have been on the G6 since August 2018. This was my first experience CGM despite being a T1 since 1991. The G6 has had a significant impact on my ability to control my A1c’s. Thank you Dexcom.

    The above being said, the failure rate of sensors is frustrating. Even though Dexcom replaces sensors for free the freequency of needing replacements due to sensor failure and related delivery times both are increasing. While Dexcom may advertise, “no more finger sticks”, that isn’t quite true given some of the quality issues with the G6.

    I can only hope the G7 will functionally be an in improvement over the G6.

  22. Good morning. So as a 46 year diabetic, the Dexcom stuff is wonderful. As for the readings being off there are some things you can try.
    1. Drink water. Hydration is important for the interstitial fluid.
    2. Rotate the insertion sites.
    I’m no doctor, but the fact is we develop scar tissue with every insertion. There is a new procedure, that uses ultrasound waves to break up scar tissue. A dermatologist may be the best person to ask if this procedure can be done to address this problem.

    • Avatar

      But mass/size of CGM’s is smaller than garbage collected from 4-5 x daily finger pokes (lancets,used test strips,packages from alcohol wipes) so I think it even may be a wash!

  23. Avatar

    Oh how I hope I’ll finally be able to wear this iteration. I tried G5 and G6 with horrific results due to my Sensory Processing Disorder. I also hope it works with InPen. The G6 is only approved to share 3hr delayed data to InPen which rendered it majority useless.

    • The way the G7 will give data will not have any effect on your disorder, unfortunately. I also agree the 3-hour delay makes the info fairly unusable, especially in real time. Let’s wait and see what happens when it gets released.

    Is there any word on G7 Tandem X1 pump software and the Dexcom App making chnages such that the user can modify things like time of day alerts/notifications for things like sensor errors, battery charge levels, insulin remaining, etc…

    • Avatar

      You can thank the Freestyle Libre for that! They’ve had that design for ages and it’s only now that the other CGM company is feeling the heat of competition that they are making some of these very welcome changes. Getting rid of the separate transmitter, changing the shape of the sensor.

      Doesn’t look like they will be able to match Libre2’s lower price, longer duration, or fewer annoying alarms you can’t shut off, but at least they are finally getting the hint that the point of these devices is to make their customers’ lives better. Period. Dexcom, Tandem, Omnipod. If all these companies would focus on that first and foremost, just imagine how much better life with these devices would be.

    hi dr. Edelman,
    I’m not having much luck with formatting while awaiting checking finger-stick BG testing sometime between 15-seconds and 45 minutes before food service here at the retirement home.
    Was diagnosed with “Juvenile Diabetes” early November 1964 after October cold (CoxsackieB?) and Hallowe’en Candy. Been injecting insulins (best guess 61,000 times since then) and most recently having fully half G6 sensors fail.
    Requirement of changing back to Regular insulin so that I had a prayer of insulin glulisine analog not causing major hypoglycemias before eating AND after digestion. Sometimes both.

    Sorry but your statement “There’s truly been no better time to have diabetes.” makes me squirm. Not like there’s a good time. I often call myself “Cranky Pete” because of bicycle-racing history when they were just inventing energy drinks. Do Team Type 1 and Team Novo Nordisk need sponsors? CrankyTired Pete

    • My mother is in a retirement home, and I feel your pain! Just do the best you can. It sounds like you’re hanging in there. Team Type 1 is a not-for-profit that can always use support. Team Novo can always use sponsors, but they’re typically big companies and not individuals.

  27. The only problem I have is the last 2 transmitters I’ve had are not lasting the 3 months the first one I got this year only lasted 40 days. It took me a month to get a replacement the one I’m wearing now gave me a message the it would be out in 2 weeks so it only lasted 2months. HELP!!!

    Can you tell me, or direct me to where can find out, why they chose to combine the transmitter and the sensor? Will the transmitters have shorter lifespan now?

    It made sense having them separate since they last three months while the sensors are 10 days each.

  30. I am type 2 for 35 years. It has been 1 year that I began an insulin for insulin resistance and it is working. I have the Decom 6, and stopped using because it was hard to place the needle. Do you think they will come out with one that I can just place on my arm like the Free Style. I test my sugars 4x a day and sometime 5.

      You can certainly use the G6 on your arm even if that site is not formally authorized. I only use it there and so do countless other people with diabetes. (Although I don’t quite follow why abdomen — the authorized site — is harder for you than arm. I find it technically easier to do on the rare occasions when I choose to place my sensor there. But I like the arm since it’s more “out of the way” while wearing it.)

    my teenage daughter can’t get the dexcom or libre to stay on more than 3-4 days. we’ve tried many adhesives, tacky, alcohol wipes, etc.

    my brother uses dexcom too but has to remove it for any sports because if people bump into it it twists in his skin and/or falls off.

    Dexcom user for over a decade now since Dexcom STS and 7, as a patient the landfill use of disposable transmitters and sensors not to mention the cost of the technology (I’m blessed that I have 0 copays with my type of insurance…. but others?).

    With the disposable nature of both sensors and transmitters, environmental impacts concern me greatly (Dexcom’s previous solution via it’s “recycling program” put the onus+cost on patients/customers which is wrong). Quarter sized integrated transmitter/sensor somehow makes me feel that even with a 14-21 day duration we will now be held hostage in the insurance supply chain with 90 day approvals.

    As an investor I realize they have to monetize their durable medical equipment and fund R&D – it’s unfortunate that it’s up to the user community to come up with creative ways to reuse transmitters (this should have been a Dexcom innovation) and sensors (just wait this will happen 🙂 – if only a balance were to be achieved between R&D funding that access to technology worldwide without a detrimental effect on the environment but there lies the rub: balancing pursuit of profits and funding vs. the greater good of the diabetic customer/patient (I use this term because Dexcom treats us as both depending on the context).

    Excited nonetheless for this new generation (from STS, S7+, G3, g4, g5, g6, g7!) and hoping that Dexcom can balance demands of customers, patients, insurance, PBMs, and investors.

    • I hear your concerns loud and clear. It’s definitely a balance, between coming up with the best technologies to treat one of the toughest diseases we have, and being totally sensitive to our environment. I am personally grateful to wear a G6 myself, and I always throw my plastic parts in the recycle bin.

If my endocrinologist prescribes G7 for me and Medicare rejects it, would I be able to pay for it out of pocket? Even better, can I get it without prescription if I am willing to pay for it?

    I am sure hoping they have direct to iWatch capability as I like to have a compact receiver rather than using or depending on the connection to my iPhone. It would also make up for the terrible G5/G6 receiver design that was a HUGE step backwards from the nice G4 receiver.

    Any idea if it will run off the same app as the G6? We are currently in the process of trying to find a phone that will connect with the G6. I don’t want to buy a new phone and in 6 months not have it be compatible with the G7.

    How can you be sure it will “also still work in conjunction with DIY Looping.” Does it use the same iOS app as the G6?

  42. The G5 sensor lasted seven days; the G6 lasts ten. I notice in using the G6 that by about eight to ten days, the sensor sticking plaster is beginning to detach from the skin. So if a G7 will have the capacity to transmit for fourteen days, the uncertainty of it remaining attached to the skin for that length of time could be a problem, especially for physically active people.

    While you note that it is a “minority” of patients that have a chemical burn/reaction with the Dexcom G6 adhesive (which contains Isobornyl Acrylate, a chemical not included in the NA-80 chemical allergen tests), for those that DO have a chemical burn, the issue is REAL.

    As we all know, diabetics tend to heal slower than non-diabetics. So the fact that some diabetics are getting chemically burned should be a red flag warning/loud alarm to all medical staff, Dexcom, and the FDA. Personally for me, it takes 2-3 weeks for the burn to go away albeit I can still see a shadow.

    I am currently trying the Libre 14-day despite the lack of similar functionality that the Dexcom G6 has. But willing to forego the lack of the G6 functionality to avoid the pain, itching and burning caused by the G6 sensor.

    • Absolutely, I get it. Thank goodness it doesn’t happen to too many people but yes, it’s real, and I would do the same as you. Hopefully the G7 adhesive will be better.

    I was on Medtronic pump, OMG, never got a full nights sleep for need of calibrations, and it was never accurate. I got G6, wow, so accurate! Hardly ever needs calibration. Easy to put on, but rarely lasts 10 days. Usually just 8 days. I hope the G7 lasts the full time it’s advertised. Can’t wait for it to come out.

    The transmitter and sensor on the G7 will be combined. It will be a fully disposable unit so you can toss everything at once.

    The G7 will have a longer wear time (probably around two weeks or so), although the exact number of days is still TBD.

    SO the EXPENSIVE transmitter is only good for 14 days now?
    How much is this going to jack up the cost?
    Just assuming all your customers max out their deductible each year so what’s the difference?

  46. To those speaking of adhesive issues. This was the answer to all our problems. We would cut a hole in the center then apply it over the sensor. sticks GREAT and NO more irritation.

    One improvement I can think of, would be the ability to start sensor warmup before the old one is finished. E.g. give the receiver (be it a separate receiver, a cell phone or an insulin pump) the ability to connect to the new sensor while still keeping the old one running, and once the new one is warmed up, let the receiver automatically switch, and give a notification that the old one can be removed. For those of us using Dexcom as part of a hybrid closed loop system, this would be an advantage, as the HCLS wouldn’t have to be temporarily disabled during sensor warmup. If the wear time was extended by just a few hours past whole days, to account for the drift that this would otherwise cause, it would still be possible to start each new sensor at roughly the same time of day.

    • Thanks for your comments and yes, some people do already start a new sensor before their old one is finished, to improve their first 24-hour accuracy.

        Thank you for you reply. I occasionally did the same when I had Freestyle Libre, but I’ve never done it with Dexcom G6. While I do find the overall accuracy comparable between the two, I’m under the impression that Dexcom G6 outperforms Freestyle Libre during the first day or so. However, what I meant was that I’d like to have the ability to keep the old one running while the new one is warming up, and make the receiver aware of both. During warmup of the new one, the reciver would use the data from the old one, and once warmup is complete, the receiver would transparently start using the data coming in from the new one, and notify the user that the old one can be removed. That way there’d be fewer gaps in the data, and I could keep relying on Control-IQ even during sensor warmup. And I do rely on Control-IQ. Since I got the pump a little over a month ago, I’ve reduced my A1c by roughly 40% (105 to 67 in IFCC numbers). It has truly worked wonders with my hypoglycaemia anxiety.
        With the G6 I would, of course, need two transmitters to make this work, but since the G7 is supposedly a combined sensor and transmitter in one unit, it should be possible. Naturally, the Tandem t:slim X2 firmware would need to be updated as well.

    I haven’t used those wasteful alcohol pads for years. I carry around a little bottle of 70% isopropyl alcohol (which I refill when empty) and tear off a corner of tissue paper or Kleenex to dab it on.

    This sounds GREAT to me!! I am SO thankful for Dexcom and any time I find myself complaining I think about the days before we had Dexcom and know that life is SO much better with it.
    It looks to me like the amount of plastic in each new sensor is so much less that changing the transmitter each time with it will still be less plastic usage. And maybe they have reduced the amount in the insertion device —we shall see. Of all the plastic that is used and thrown away, this NECESSARY usage is one I will allow. (And I am conscious and cautious in all other areas with plastic usage.) Surely they are doing their best to offer us all the best technology as soon as they can. To offer a new generation every couple years is pretty phenomenal. I personally like the idea of a new transmitter each time. To not have to worry if your transmitter is going to die in the middle of a sensor session vs losing a few valuable days by replacing it earlier than needed…that will be nice. And, those last couple weeks on an aging transmitter usually have a lot of “no data” time. This all sounds and LOOKS amazing!!!! That SLIM design!! CAN’T WAIT!!!! Thanks for the information! And thanks, Dexcom!

    I’m on a Libre 14 system. The first day numbers are always off on the high side. I like the idea of inserting a new sensor 24 hours before the other sensor expires. Then start the new one up the next day. This I hope would give a much better first day of level readings. I’m not on a pump so the first day I’m doing finder sticks. Ugh. Any other suggestions are welcome. Thanks for sharing.

    Any idea if they are changing the adhesive for those of us who have sensitivity to the current adhesive that they changed at the end of 2019? BTW, I have a great tip which works for me. I put an over-patch on my skin and then line up the sensor over the hole that is already cut out. The over patch gives me enough protection so I no longer get the burns, scarring, and itching I was getting. My husband came up with this “hack”. Thank goodness for his support (He was probably just sick of listening to me complain and walking around with a wife that had unsightly burns all over her arms lol.

      We have heard they are working to improve the adhesive, but great idea from the hubby in the meantime!

      Please elaborate on the over-patch hack?
      what material do you use to create the hack.
      How does the whole thing work?
      I’m getting a Dexcom for my wife
      and as a mechanical engineer I’d like to take advantage of husbands idea!

      Thanks for your help

      PS I’m right about to pull the trigger
      and was checking for G7 availability.

      • Hi Bob. I use the free overpatch from Dexcom. Just call them and ask them for a pkg. There are 10 to a pack. I clean my site with alcohol, let it dry, then put one of the overpatches on my site. Next I line up the sensor (with the sticky tabs taken off) with the hole in the overpatch. There is a little wiggle room as the hole is bigger. Insert the sensor as instructed and press around adhesive to secure it. I no longer have a rash or welts! Sometimes nearing the end of my 10 days I have to put an overpatch on top of the other overpatch bcuz it will start curling. I am very happy Dexcom provides these for free. Let me know how it works:)

    T1D since Nov 1976… and about to switch from Medtronic pump – forced to them when my lovely Animas went under (boo hoo!), to Tandem.. and investigating all the latest about Dexcom G6. Great to hear about this new and improved version on its way down the pipeline. I’m also using Libre, and yup, it can be off a bit, but geez louise… I remember testing my urine and comparing the colour of the bubbling liquid in a test tube to a colour chart, then guessing the BG level! When it became available to test your actual blood at home, finger poking was a new found blessing back then! lol And, I had to do it with a small blade on my own, before they came up with a launcher to hold and launch the lancet into your finger. I’m just happy that we keep advancing quite a bit faster these days, compared to the 70s and 80s. 🙂 Thanks for the updates!

    • Stacey,
      Your post really brought back memories of the test tube urine testing, stabbing my finger and the guillotine which was a godsend! I do hope you are well!

    Will the G7 offer Apple Watch direct integration?

    This sounds exciting. Will the Dexcom company update anyone who already has the G6 or will one have to contact their doctor to get a new one. When I had the G5 they sent me the G6 with the computer update disc which worked out really well. I sure do like the Dexcom and no more finger pricks (or back to the 50’s into the early 80’s for urine testing). The changes made in diabetes care and products over the years has been great. My mother had to boil syringes and sharpen needles. She started with benedicts which had to be boiled to get a urine test result. What she went through for me so I could be here today and move forward with the new discoveries that have been made to move ahead with diabetes control. Bless her heart. And thank you Drs. Edelman and Pettus for your wonderful work with TCOYD.

      My mom was the same way she had to boil her needles and do iron test strips and call the doctor every morning with the results to get her dosage amount of insulin she had to take and she had todo the every day 3 times a day. And I thought I had it rough growing up till she told me that story. Lol.

    Has anyone heard of a Dexcom g7 release date yet? I am very excited to try it.🥰

    I switched from Freestyle Libre to G6. While pleased with the accuracy and software interface, there are several cons:

    10 day life
    Non-integrated sensor and transmitter
    Adhesive is difficult to remove and scars skin
    Restricted application sites

    Worst, on my second time using it a lot of blood gushed out that got contained within the adhesive but i was worried it may ruin the sensor.

    Excitedly looking forward to G7. Do they have a launch date?

    If my medical insurance covers the G-6 sensor, do you know if it will also cover the G-7? I understand that different medical insurance companies cover different medical devices. I was just wondering if you have already contacted the insurance companies for their coverage on this new G-7 device.

    Hello. Can anyone give me a target date for the release of the G7? My 13 YO nephew is eagerly waiting. Thank You very much.

    Will the adhesive be improved at all on the g7 from the G3,G4, G5, and G6. I am considering upgrading to the G7, but don’t want to unless it is improved. That is one of my biggest cons with the G6 currently.

    • Avatar

      Considering how many people complain about it, they should listen to that. Though I personally think Dexcom has the best adhesive of the sensors I’ve used. The first one I had was an early Medtronic sensor that had to be covered with an overpatch. The one I was offered was more or less completely air tight, and I had to use a special wipe to get rid of the adhesive. It left a nasty, itchy red square on my skin for several days after removal. Felt more like amputation than patch removal. Then I had the Enlite from Medtronic. That one left a slight rash, but its main problem was that it fell off a little too often. Then Freestyle Libre followed by Freestyle Libre 2. Those left a rash, but hardly ever fell off. The Dexcom G6, which I have now, sits just as well as the first one I had from Medtronic, but without its drawbacks. No oversized overpatch, no rash, no itching, almost painless removal.

    I’ve been Type 1 since 1965, back in the days when I had to boil my glass syringe and stainless steel needle before every injection, and the detached needle was the size of a wooden pencil lead and had to adjust my blend of NPH and R. I only started with a pump about 20 years ago, and currently use a Medtronics 670G w/Guardian GCM. Been happy with it and it works great when I periodically do extended water fasting – have to constantly adjust my basal rate and was just down to 20% on the 36 day water fast I just finished. I still work full time but am about to retire, so need to find a pump supported by Medicare. My endocrinologist likes the Tandem t:slim X2 and Dexcron G6, but I like the G7 because of size and convenience. Will maybe wait for the G7 availability, but will the Tandem w/G6 or G7 allow me to safely fast and adjust my basal rate (don’t yet grok how they work vs the Medtronic). From comments, they sound great! I’ve enjoyed reading your experiences.

    • Congratulations, since the Dexcom CGM is totally awesome and so much better than the Medtronic sensor! And the Tandem pump is awesome too. The system has a modulating basal rate based on your predicted blood sugar. As your blood sugar starts to drop when you’re fasting – if it does – the basal rate automatically turns off or adjusts downward.

  64. Type 1 for 55 years – on pump since 1997. Have had 5 pumps and now on Medtronics 770G. Tried Medtronics Guardian CGM system and quality of life poor with 4 calibrations per day including 2:00am! Switched to Dexcom and best thing I ever did! Dexcom more accurate than Guardian and much easier to use. Have Dexcom G6 now and interested in switching to G7 when available and my insurance will cover.
    Any idea if I will ever be able to sync Dexcom with my Medtronics pump – which I am now running on manual mode. Last four A1Cs less than 6.

    So will you still need location turned on, on your phone. Dexcom says they do not use that information but every other app on your phone does.

    I have been a type 1 since they renamed it. I was an adult onset juvenile diabetic in 1964. I used Dexcom g4 and g5 when they were out but discontinued both due to their inaccuracy compared to finger sticks. I have used the G6 for about five months now and have stopped complaining to my doctor about all differences with my meter that are less the 20%, but still record all differences. Some have been over 100%, My A1C for the last several years has been between 5.3 and 5.7. My last A1C was 5.9 in January. I have hopes for the G7 and will get one as soon as my doctor says I can.

    In Mmol/L, how high will the graph go before it simply reads HIGH? I occasionally run into situations with my diabetes where I end up over 22.0 and not knowing the exact number can make bringing my glucose back down more difficult and stressful. I’m not sure why the G6 is set that way, and I’m hoping the graph will go a little bit higher on the G7. All things considered I’m very excited for the G7.

    • Avatar

      If your glucose level is that high, you should prick your finger to verify it anyway. I do not know the exact reason why cgm sensors usually have a lower high than the meters, but I’m guessing it has to do with not being as accurate because the glucose is measured in tissue fluid, not in blood, and that the inaccuracy gets worse if the glucose level is too far from normal levels. I’ve had several different cgms and fgms, and as far as I recall, they’ve all had their upper limit around 22 mmol/l.

    • We don’t believe that information is out yet, but write to Dexcom and send in your suggestion!
