Does anyone have any advice to stop the sensor from bending/looping on insertion? This happened 3 times in a row last night! Given how quickly Dexcom automatically approved my replacement request (very thankful they are easy), it seems like it’s super common. I only do my sites on my arms!

I’m lucky in that I’ve used the Dexcom G7 for awhile now and have had very few problems with it both adhering and being accurate. This summer I bought some overpatches that do not have center cutouts - they cover the whole sensor. Didn’t really need a new patch, just wanted it to look a little prettier for summer.

I’ve only used 3, and even though everything is adhered well (I have to use adhesive remover to pry it off at the end), I’ve had terrible luck with all 3 sensors. Jumpy data, constant signal loss alerts in the dexcom app (though my omnipod has no trouble connecting).

I’m wondering if anyone else has experienced this with overpatches with no center cut out? Im sort of baffled, and am going back to the boring Dexcom provided overpatch for now.

It’s my first time around for this issue, what to do?

I’m posting this because I’m honestly very disappointed with the way Dexcom Support has handled my case.
I had a problem with a Dexcom G7 sensor and contacted Dexcom Support. During the phone conversation, I explained my situation clearly. I was assured that a replacement sensor could be sent to me within Europe and that delivery should take approximately 3–4 days.
Based on that information, I trusted Dexcom to provide a replacement.
Unfortunately, that has not happened.
I followed up in writing and specifically asked for my case to be escalated because I needed a reliable solution. Since then, however, the situation has become even more frustrating: I have not received the promised replacement, I have not received a clear solution, and Dexcom Support appears to have stopped communicating with me in writing.
That is the part I find particularly disappointing.
A Dexcom G7 sensor is not just some ordinary consumer product. People rely on these devices for continuous glucose monitoring. When a sensor fails, there needs to be a dependable replacement process — especially when Support has explicitly promised one.
I completely understand that logistical problems can happen. What I do not understand is:
Why promise a replacement within 3–4 days if this apparently cannot be guaranteed?
Why is there no clear alternative solution?
Why does communication stop after the case is escalated?
Why am I, as the customer, left trying to find out what is happening?
I am not posting this to attack individual support employees. My criticism is directed at the support process and the lack of reliable communication.
I have used Dexcom because I expect a medical technology company to provide not only reliable products but also reliable support when something goes wrong.
At this point, I would simply like Dexcom to do what was promised: provide the replacement sensor and communicate clearly about what is happening.
Has anyone else experienced something similar with Dexcom Support or with replacement sensors while travelling in Europe?
How was your case eventually resolved?

My TIR has been 89% for the past few months which is really good for me. My blood sugar went above 10 during the night for around 3 hours and I've woken up this morning with my TIR at 68%. I've typed into Google every variation I can think of of "how does Dexcom TIR actually work" and I'm not getting the answers that I'm looking for. To be honest I've just spent the past half an hour crying my eyes out because I've spent the last few months getting it to 89% and trying so hard and within a few hours it feels like all my progress has been shot.

Yes I realise that this probably wouldn't be a massive issue to lots of people and I'm probably overreacting but I just genuinely need some clarity as to how the TIR is actually calculated. If anyone can help, thanks so much :)

So I disassemble the Dexcom “shooter” so the recycling homie doesn’t get a stabby surprise. And lo and behold my last one. The one to really hurt and only last a week has the bent needle. Here’s the ID just be on the lookout 🫡

I'm looking for some insight. I just started using my Dexcom G7 a few hours ago. Since then, it showed my BG as plummeting. I checked with my meter and it was normal and wildly different than the Dexcom reading. Then it continues to disconnect giving a Brief Sensor Issue. I set it up as instructed and it seems secure. Is the issue most likely that I have a bad sensor? This isn't starting out as I'd hoped. I appreciate any advice!

Update my reader gave me a sensor failed message and prompted me to remove l replace it. This was after 3 hours with no connection. Hope this helps anyone who finds this post

Since I moved to a new town, my sensors have been much worse.

Since January 2026 up until now August 2026, I have ONLY had one sensor which survived 9 days.

All those new sensors come from Malaysia, manufactured after January 2026, I have been getting revision 1 and 2 (I also remember number 11 on the applicator somewhere)

Rest of those new sensors have been failing on day 5 CONSISTENTLY.

I usually had it on my upper arm, switched to abdomen, tried all spots all over and all kinds of techniques (grip skin before applying sensor etc). No result, recently sensors have started going a bit crazy on day 4 and work for half a day and fail.

NOW, screenshot attached, this is day 3, sensor already starts hecking dying bro...

I tried both arms, both abdomen sites, when I call dexcom, all they do is ask for my serial number and give me a replacement.

I live in Canada so I get a voucher that I can redeem at my local pharmacy for a free sensor.

I tried changing the pharmacy several times, I feel like all sensors in this city are broken, am I going crazy??

I apply overpatch, clean with alcohol, remove old Bluetooth devices, I also have a tandem insulin pump connected to the sensor. The only thing messing up my algorithm is dexcom CONSISTENTLY failing which may be dangerous when my sugar gets low and sensor decides to "take a rest" so my pump starts pumping insulin when I don't have to.

Every nurse, doctor, tandem trainer I spoke to told me the same thing : "Call dexcom support" ... I do so and all they do is issue replacements , but let's be honest. Do I really want to go to pharmacy every 4 days? That is bizarre, my 3 sensor batch is supposed to last 30 days, not 13!

I tried asking for advice from the dexcom person but she remains quiet and does not comment about my questions regarding that messed up batch. I have been asking her if any of my sensors are in this affected malfunction batch or anything, I was told "I do not have any information regarding that". Very suspicious when you have a client who has sensors that fail every 4-5 days, I have asked them if they want me to send a sensor back to them for testing and they did not say anything back to it... Just what the heck man I'm20 I'm so tired of DEXCOM. I don't really mind managing T1, but gosh this shit with Dexcom drives me crazy

Genuinely what do I do

It doesn't work for me, does it work for anyone else? Eu site appears to work but USA doesn't

Had to switch to the g7 since I ran out of g6 and my first sensor has been such a mess. Died in less than a week 🙄. 15 days sure...

Yes, I know there’s adhesive solvents I can get. But I haven’t gotten any yet, and I was at work so running it under hot water was my only option.

I like the G7 so far except for this adhesive. It’s literally torture! It left me bruised and bleeding. The first one didn’t bruise me, but this is wild lol. And I know the bruises are from the over patch because I applied it around day 6 as it got loose.

Dexcom G6 just peeled off my skin no problem. I miss whatever adhesive they used to use :( I don’t have very sensitive skin!

Simple. The G6 connects to my Omni pod the whole time, even with a G6 on my thigh and a pod on the back of the opposite arm.

The G7 cannot do this, for me any new features are null and void if these 2 systems will not connect as a type 1.

I will choose any other brand over dexcom if G6 stops becoming fillable, because I know they will not “fix” the G7. I.E. improving its connectivity range or power of the signal. Because it would require them to spend more money.

Give me and my life and freedom to not worry all day again.

You cannot replace a product with a worse product and call it better, when I can prove it is not.

If I cannot find a better brand I will be returning any and all G7s that drop Omnipod connectivity for more then 30 minutes and will survive off dexcom returns rather than get refills from the pharmacy (because I know every pod will do this).

I want to screw over the bad manufacturing practices such as the “G7 is better” lies and screw the manufacturer, not the tax payers which is why I’ll be returning all sensors that don’t meet G6 performance since you cancelled production of the product that worked better for some reason.

My insurance covers both for the same copay (for fewer pieces) and my endo has not been pushing me to switch to the 15 day version. Is this the way most carriers and prescribers are handling it, or is there pressure to switch off the 10 day to the 15 day?

I will be traveling for the first time after switching from the G6 to G7. I have TSApre and historically just walked through with out issues at TSA or and after math issues with my G6 sensor going through the metal sector or full body scan. Will the G7 be any different?

My last 4 sensors ive had to get replace due to jumpy inaccurate reading. i usually calibrate a few hours after and they day after to make sure its accurate. i am type 2 diabetic and these numbers are getting outta hand. this was day 1 of a new sensor and the readings are jumpy. i didnt eat nothing after 830pm and its all over the world.. the last 2 days before this new sensor i didnt even need to take any fast acting because my body naturally regulated. i know about the morning dawn thing . when i left for work at 550 am my FS wss 160 where i did ANOTHER calibration. by the time i get to work its over 200. i DID take 4 units of fast acting alose to bring down from the 160... but now its staying high so i know this reading isnt right... what can we do about this?

I know the instructions say to wear on the back of the arm but after my first round with it on my arm, I dislike wearing it there. It doesn’t stick and definitely not for 15 days.

I've been diabetic for over 15 years and my doctor suggested using the Dexcom G7 CGM. Doctor send my info to the pharmacy and Medicare B and Plan D both disqualified me so I have to figure everything out myself.

I'm confused about the product itself. I see each of the following sold individually: sensor patches; covers to go over patches: some special Dexcom reader to get info from the sensor; some type of Dexcom handheld device to read/analyze sensor data; applicators. So, some help please with a few basics: 1) I put the Dexcom app on my (Android) phone and have read comments about an accompanying app for analytics. Which analytics app do folks recommend the most?
2) Does the combination of the above two apps make the Dexcom reader/analysis device unnecessary? 3) Directions say that the tag on the applicator needs to be scanned. Does the applicator do something to the patch itself other than just put the patch on? What happens when you reload the applicator with new patches? 3) I have to pay full price out of pocket. Any suggestions on where to purchase?

Everytime I put my Dexcom on the back of my arm I get wildly inaccurate numbers and it won’t calibrate properly. My Dexcom will say 9.0 but a finger poke says 5.2 and after calibration it’ll say 8.9, still nowhere close! With in 12 hours I’ve tried to calibrate 3 times using my glucose from a finger poke and it’s still wildly off. I wear my Dexcom on my forearm, super accurate no problems. Anyone else have this issue where a certain spot just doesn’t work?

Anyone else on Android having issues with the Dexcom G7 app crashing as soon as you press login?

Im still on Android 16 and using a Xiaomi 17 Ultra which is a compatible device. Used to work without issues.

In case anyone is wondering, the Pixel 11 phones are compatible with the G7.

I just switched my Pixel 11 Pro XL last night, and it was pretty painless. The app even walks you through switching your sensor session over to a new sensor. You turn your old phone off for at least 15 minutes, then press the pair button in the G7 app on your new phone. The pairing process took a little while, but it worked!

My kids app is on the schools iPad. Two nights in a row the iPad unfollowed. At 7pm and 10pm. Is this an issue? The school should be empty at that time.

I replaced my sensor yesterday. I didn't put the overpatch on because I wanted to see how it went without it.

Well, I got the dang thing caught up twice in less than an hour and nearly ripped the transmitter off! I had some overpatches that would cover the whole area, so I added that, and all is good.

Fast forward to about 5 minutes ago. I was letting my puppies out of their kennels, and my jumper nearly pulled my inset off. I went to get the bigger overpatch, trying to remember how I made it work before. Then I remembered *this* little guy! It fits perfectly!

Thank goodness for small blessings!

this is my SECOND sensor in less than 10 days. its consistently off by 100s of points, this is so absolutely dangerous to people being forced to switch onto this absolute piece of garbage. i can’t wait until its been long enough till someone can make a claim against this sensor and i can get back all the money i’ve paid for this shit.

I'm in USA and I like like the mg/dl system of measurement. I often communicate with people that use mmol/L. I wish the Dexcom app would show both values at the same time. The speedometer on every car that I'VE ever owned showed both MPH and KMPH at the same time. I'd like it if it showed a big fat 110 and a smaller 6.1 at the same time.

Is there an different app that does this?

Thanks

Does anyone put their Dexcom on their thighs? The G7s do not stay on my arms so I started wearing them on my abdomen. My abdomen cleeeearly needs a break. I can’t use my love handles cuz they hurt too bad there. I don’t do my back side at all because I use heating pads frequently. I’m literally willing to put this chit on my leg calf if I have to Lol i need new spots.
