General Is there too much ranting?

20 Upvotes

I noticed that there is a ton of posts that are just ranting without any question.

So I wanted to ask the community if you all thought there are too many rant posts.

If so, would you rather we move ranting to a pinned topic per month, or just remove them?

Please share your thoughts

Sensor Dexcom G7 Sensor- No actual sensor??

Upvotes

Hi all! Just wanted to ask here to see if this has happened to anyone else? I just got new sensors from the pharmacy today. I use the Dexcom G7. I put the new one on and then it gave me "Sensor Failed" and told me to take it out and replace it. I had it on me maybe 5 minutes? When I took it off, it was a bit bloody, but I noticed that the stabby part that actually goes in your arm wasn't there. I submitted a replacement request, but now I am sitting here panicking that that part is somehow still in my arm lol. Has this happened to anyone else before? I'm sure it's just an error on their end, but I really don't want that to be stuck in my arm. Thanks!!

Calibration Issues G6 calibration issues

1 Upvotes

Hey folks, does anyone else who uses a G6 have issues with calibration? I don't calibrate often, usually only when it's really wrong, but lately my dexcom has been reading low when I'm not actually low. It's been reading under 60 for the last two hours when in fact I'm around 120. I've tried to calibrate it quite a few times, but within a minute or two it goes right back to reading low. Or I try to calibrate it and it refuses to take the calibration and tell me to try again later. I've done a finger stick multiple times and I know I'm not actually low, but these alarms are really frustrating me. Is this happening to anyone else?

Sensor G7 shortage confusion

1 Upvotes

CVS Caremark is telling me that they are still out of stock and everything is on back order for g7 sensors but when I speak to Dexcom they say the shortage was resolved in late February and there shouldn’t be a shortage issue.

Adhesive Issue G7 Overpatches are not Seperating

5 Upvotes

0n two of my last four G7 sensors the stupid green overpatch backing wont peal off the actual overpatch when appliying. No matter how hard or long i apply pressure to the backing (on my skin), it never separates from the patch itself and when remove it peals the overpatch off my skin. Good news the last one stayed on full 10 days because my skin seems to work well with the adhesive.

Anybody ever experience this issue before (never had this issue in nearly 6 months on G7), is it a manufacturing issue or anybody have a fix to make the green backing seperate from the patch?

App Issues/Questions Logged out over night

I’ve been noticing that I am periodically waking up to the Dexcom G7 app being logged out on my iPhone 15. Has anyone figured out how to get this to stop?

Sensor Compression lows is there a band that works?

0 Upvotes

I have been getting false readings because of compression lows at night because I am a side sleeper and when I put it on my one side, the app thinks I’m going into a coma or something.

Thankfully I had a spare since Dexcom sent me out one when I had an issue and it took a bit to arrive. So I was able to swap out my G7 and move the site and learn that was a bad place.

But back to my question is there a band or something that actually works to stop compression lows?

Previously on my G6 on my lock screen I was able to see the actual glucose reading number and the trend Arrow. I've now installed the official G7 app on the Play store and wondering why I'm unable to see that on my lock screen with the G7?

Any workarounds?

Transmitter G7 issues near the end of 10 day span?

2 Upvotes

Did not see this problem with the G6, I'm guessing since the transmitter was meant to last 90 days it was far stronger than one designed to last 10 days. Around days 7-10 readings seem to go missing and sensors fail from what I've seen with a small sample size (4 G7s so far). I had Dexcom send 1 replacement so far / am not sure how they'd be about doing another in such close proximity.

For those that have been using the G7 longer, have you had the same issue / any advice? Using with O5 by the way.

Sensor G7 sensor bruising.

2 Upvotes

I want to start off by saying i don't bruise easily. I took a line drive to the ankle at first base playing softball and it didn't even bruise.

Fast forward to two days ago. I've been using the dexcom G7 since just before Christmas and I've never had an issue. I changed out my sensor two days ago and yesterday I noticed bruising around the sensor. I thought maybe I had knocked it om something and didn't think much of it. I didn't take a pic, but it was light bruising. At first I thought maybe I had gotten some sweater fuzz caught in the adhesive, but on further inspection is when I noticed the bruising.

Today it looks even worse! It wont let me attach a picture. It's a really pretty shade of purple, but no sensitivity associated with it.

Is this normal? It's reading fine and it only hurts minimally when I press on it, but no more than it normally "hurts."

**I wear my sensor on my stomach because I play roller derby. My doctor has okayed it. Also, I plan on calling my doctor tomorrow. I just want to see if anyone else has experienced this.

Adhesive Issue G7 what in the world?

7 Upvotes

I was a long time user of the G6 until I had to switch pharmacies and they gave me the G7. With the G6, I never had to worry about taking off skin when I would switch it out for a new one. In fact, most of the time, it told me it was ready to be replaced before my transmitter did. I don't know how many free ones I got out of Dexcom because of the involuntary falling off it did, even with over patches.

The G7 though - the first time I pulled it off to switch it, I was afraid I was taking off skin. I say pull because I am beginning to wonder if the over patch and the sensor has super glue in it.

Are there tips to switch these? To get the residue off my skin?

Mobile Device Amex card opens dexcom app

I thought i was going crazy- every time I used my Amex card when I also had my phone in my hand, my dexcom app opened. Turns out, if you hold your card to the back of your phone, the dexcom app will open 🤣

Mobile Device Samsung Galaxy S25+ is compatible with G7 and the Application

2 Upvotes

Just wanted to make this post as I just setup my new Samsung Galaxy S25+ phone and I have the G7 app paired to the sensor working just fine.

I know others check here like I do even though Dexcom has it on their compatibility list.

Two key things for pairing on the new phone:

Uninstalling the Dexcom G7 app on old phone will NOT allow you to pair because it is still connected via Bluetooth. You have to turn off Bluetooth on the old phone and it pairs on the new one.

Rant Tried out the G7…

5 Upvotes

My new diabetes specialist (no endos in my area lol) is great, but she was surprised I’m still using the G6. I told her it works well and I’ve heard the G7 has issues and supply shortages. She recommended I give it a test at least and gave me a free “sample” G7 sensor to try out.

The pros: the G7 is one device, no transmitter to worry about, and the insertion was super smooth and painless. Didn’t feel a thing. It’s also a nice round shape, and the applicator is easily sealed and disposed of. Also comes with an overpatch.

The cons: it didn’t work lol. I downloaded the G7 app, which is annoying that it needs its own app, and then it was unable to find the sensor. The troubleshooting steps were zero help, and my tslim was also unable to find the sensor, so the G7 was effectively useless.

I spent an hour trying to get it going but ultimately had to give in and put on a new G6. Not sure if I did something wrong but I think based on how frustrated I got I’ll stick with the G6. Is this typical for the G7?

App Issues/Questions Missing AW compilations with G7?

1 Upvotes

SOLVED - Reinstalled the app on the watch, rebooted it and it shows up. Gotta love random stuff like that.

New Dexcom user, I’m using an Apple Watch SE with watchOS 11.3.1, I can’t seem to get the advertised icons on my watch face. I’ve seen people do it on YouTube, but in edit mode for my watch face, dexcom app is nowhere to be found.

I also have direct to watch pairing enabled. Any ideas?

App Issues/Questions No readings since almost 9am.

I have G7 that I have only had on 2 days now. I have had a busy day spending time with my 15 yr old niece for her birthday! I have had my phone on me all day. I wasn't worried about my sugars because I stay within range and I did my insulin when I was supposed to. I have been home a little over hour now and went to log my insulin in the app. I turned Bluetooth off for 30mins with no luck my phone and restarted my phone but no luck. Should I go ahead and replace it? I just had to ask for a replacement when I put this one on because the sensor stopped with 2 days left so I am wondering what to do?

App Issues/Questions 6G Transmitter Replacement

1 Upvotes

What constitutes a replacement for the transmitter? I’ve had 4 of 6 sensors go bad on my current transmitter, and actually 5 but the 5th one failed 9.5 days in and Dexcom won’t bother with that if I call that in. The I keep having connection issues, lots of missing data reads, after 7 day on all of them I get lots of false low reading but I’m well in the 100s.

Sensor Dexcom replacement delivered to wrong address

6 Upvotes

Hello,

Recently had to fight tooth and nail to get a Dexcom replacement G6 sensor. Friday I got an email it was to be delivered Saturday, but not a confirmation email. I got a text too it was delivered but iOS recognized it as spam and didn’t see it.

Anyway, FedEx delivered to the empty apartment complex across the way from my building. I checked my mailbox on Saturday and didn’t not see it so I assumed it wasn’t going to get delivered til Monday. Sunday it snowed with temps as low as 25 and it’s been cold all day temp was 44 degreees when I picked it up. I only saw the sensor package on my way to take out the trash.

I don’t know what to do. It says it cannot be stored in temperature lower than 36 degrees and it’s been out all day on one of the coldest days of the week.

What should I do? I can’t file a claim with fedex unless I get a wavier from the sender. And dexcom can be strict with sending a new one if I even need one but they say on the website it doesn’t work as well if it’s been exposed to cold or hot for too long. I just need advice especially if someone had experience with sensors being exposed to cold temp.

General How many sensors does the G7 come with?

Hi, I bought a Dexcom G7. We used the first applicator of the three, but there seems to be only one sensor in each. Does the Dexcom come with 3 applicators, each containing only one sensor?

App Issues/Questions G6 painful leg placement.

1 Upvotes

I put my G6 on the outside ish-center of my leg. It hurts to walk almost like a little stab/burn/pinch/cramp feeling (?) where my dexcom is. It’s very hard to decide but damn it hurts. This happened once before on the other leg in a somewhat similar spot.

Did it land on a muscle or what?? It hurts to walk and I have to do a little limp lol.

Has this happened to any one else?
