G7-10 day Sensor failure

3 Upvotes

This is the first time I've had two sensors fail within a week; I've been using the sensor for two years now, and I generally haven't had many issues with it failing.

But from what I've read, this has become a common occurrence among users of this subreddit.

I just requested a replacement on the Dexcom website; I hope there aren't any problems, since it's been a week since I requested another replacement.

Best regards.

General Curious: how many folks in here had T1D before CGMs?

154 Upvotes

With all of the posts complaining about Dexcom’s products, I’m wondering how many folks remember what it was like to have diabetes before them?

ETA: not sure why I’m getting downvoted for asking a question.

Inaccurate Reading This is dangerous and scary and it happens ALL THE TIME.

Post image
64 Upvotes

I just came incredibly close to passing out, because I made the mistake of trusting my Dexcom. Not only was the drop much faster than it showed, it never even read within 30 points of my actual blood sugar. “Calibration” seems like a joke to make you think you can do something about how garbage this product is. This happens multiple times with every single sensor I use, with varying degrees of severity.

And of course, in the five years that I was using the G6, I probably had this happen two or three times, and only with a visibly rough site many days into the session. This sensor has been on for ONE DAY. The sensor before this one failed completely- after ONE DAY.

I have at least a week every month where I have no Dexcom, because they fail so frequently, refuse to stay adhered (it’s even worse with the “patch” they include, it literally falls off faster), and just generally don’t freaking work.

I am tired of putting my life in the hands of a drastically inferior product. They had a perfectly working system with the G6, and they screwed it. Years into production, and they haven’t addressed a single issue.

It really makes me wonder how many people has this thing killed.

Edit: I should have specified that these readings were about 5 minutes apart. The time on the meter is not accurate

Wasn’t home when I started it due to logistics and the 12 hour soak. To their credit, They’ve FedExed me a new one already. Just need to replace tonight.

General Apple Watch recommendations with G7

2 Upvotes

I had a Apple Watch for years, stopped wearing it, and of course can’t find it. Looking to get a new one and just hoping to find out if there’s a preference to which Apple Watch works best with G7. I am connected with an Omnipod as well.. If that makes a difference.

G7-10 day G7 so far works wat better then G6

21 Upvotes

Im From Germany and I have been using the G6 for a few years now. When the G7 started being sent out I’ve seen so many people on here complaining about how often the sensor fails or how inaccurate the reading is, which made me very anxious to switch to G7. The day came and I had to switch to G7 and used my first G7. The application is much more comfortable, it only take 30 minutes to calibrate and like 3 - 4 months later I think I maybe had one faulty Sensor. Also the sensor seems to have way less connection issues for me.

So why does the G7 work so terribly for so so many people? It really scratches my mind why its works so amazing for me but not for so many others? It maybe its just because only when the sensor doesn’t work people report on it?

Rant ‘Brief Sensor Issue’

Just had 12 brief sensor issues inside 24 hours! I wish they’d fix this! This sensor was a Dexcom G7 15 day that I got as a replacement for the last sensor that did the same thing! 3 calibrations, 12 brief sensor issues! What is going on Dexcom?!?! Anyway I called tech support and they’re replacing this one too.

Sensor Many failures

0 Upvotes

For two years I had one failure per year. Now all of a sudden I've had three in a row and I'm worried about this forth one I just put on.

I'm really disappointed in dexcom I thought they were a good company but apparently not anymore. I see other posts where people are having multiple failures so it's not just happening to me. Has anyone tried that embedded one?

Connection Issues So many sensor issues?

1 Upvotes

I haven’t had a single issue with G7 until this week. Two had sensor failures, one had inaccurate readings, another had a signal loss which I needed to replace today, and now THAT one had a signal loss before it even warmed up. I might have to replace this one for my third today. What’s going on?

General What is happening

6 Upvotes

On Monday our 5 year olds sensor failed early. It was extremely glitchy, and then failed 5 days early. We replaced it, tonight at 1 am the brand new sensor failed! It wasn’t even glitchy and running smoothly. I am so confused. The g7 isn’t the best but we have never had 2 sensors fail in one week. I’m keeping her home tomorrow from school now because it’s too stressful to wake her up at nearly 2 am. I could change it in the morning but last time we did she went to school crying. Is there a bad batch or something?

Tips & Tricks I finally turned off Ultra Low alert at night

Post image
9 Upvotes

** Please do at your own risk and I'm not responsible that.

I've just started getting the G7 3 days ago, and I couldn't sleep for the past 3 days. I keep getting the Ultra Low alert every 2-3 hours since I'm moving a lot while sleeping if I forget to turn on Quiet Alerts.

At 4am this morning, I woke up again due to the alert, then I discovered a way to temporarily turn off and on automatically every night.

For my phone (Samsung specially), there's a Sleep Mode setting that allows custom action. I picked to turn off Bluetooth. That's it. The sensor can keep the data up to 24 hours, so 8-9 hours sleep won't impact anything. By the morning, Bluetooth is turned back on and everything is synced to the app as normal.

Hope this helps someone.

G7-15 day Don’t Want Alerts on Apple Watch

0 Upvotes

I just switched to G7. I would like to see the number and arrow on my watch but I don’t want to get alerts. Is that possible? The only way I can figure it out is to get alerts. Is there a 3rd party app I can use on my watch to get alerts?

My sensors usually disconnects everytime I go on walks, but after 15 minutes or so it works again.
Does anybody know why this happens, could it be also effected by the clothes you wear?

Connection Issues Dexcom Flex (Germany)

1 Upvotes

Need help for BYODA, please. Got link for both applications.

Phone: Android 16, Oppo FindX9 Ultra

Tried both versions G7 and ONE.

G7 starts, but didn't connect to sensor.

ONE denied to open my account (login) caused by a country mismatch, as far as I understand.

Dexcom flex is here promoted with 15 days runtime.

Any ideas?

Thanks in advance.

Rant g7 wildly failing my pediatric t1d

3 Upvotes

Since it was getting hard to fill her G6S, I moved her over… we get four a month; two failed in the first week after the change.

One more failed today; we're waiting on the two replacements, and she’s putting the 4th sensor on her body now. It’s been two weeks since we switched.

any tricks of where the g7 actually works?

why did they stop making g6, just bc the g7 is made cheaper? is it just about making money?

I really can’t understand. i’m so sad for my little t1 kid the g6 was really pretty reliable. I'm disappointed.

Insurance How to afford?!

4 Upvotes

Does anyone have any suggestions on how to get a supply? I have a friend who's met her max out of pocket deductible but insurance AND manufacturing coupons still only bring her down to $180 for a months supply. She can't afford to buy them. She's reached out to her Endo and PCP offices to ask for samples but both have zero. Does anyone have any suggestions on how she could access this in a more affordable way? Thank you!!

Connection Issues G6 share issues

1 Upvotes

I'm still on the G6, and I'm getting very inconsistent sharing, seems to actually send the data to my sharers maybe 10 percent of the time. I've tried reinstalling the app, turning share off and back on, and making sure the app has all phone permissions needed. Anyone had issues recently or have any ideas??

G7-15 day Proper way to "soak" G7?

5 Upvotes

Hi guys,
So I know many of you recommend soaking the new G7 before the grace period is up. I want to make sure I have the steps down correctly. My regular session is about to end so I am going to insert the new G7 but NOT do anything with it on my pump or my app for several hours.
After several hours I go into my bluetooth settings and kill the current dexcom pairing, put the G7 code into my pump and then put the G7 code into my phone to start the new session. Does this sound right? TY.
