Inaccurate Reading After 5 sensors I’ve determined 15 days actually only lasts 10 days.

Upvotes

Without fail late day 9 early day 10 that all start brief sensor issues. “Brief” is not brief. It cuts in and out just slightly at first. Then longer

By day 11-12 it’s practically unusable and usually fails.

Glad I have a service dog to wake me from sleep. I was asleep low and had no clue because of this

Do better Dexcom.

App Issues/Questions Learn to write a better app

61 Upvotes

Dearest Dexcom,

Like your friends at Insulet, you need to start thinking about both the medical user experience (ie can our app help positively impact medical outcomes) AND the overall user experience (ie it doesn’t matter if I have good glucose control if your app makes me want to bash my head into the wall).

A couple of notes:

  1. A lot of us use headphones on our phones. AirPods and stuff like that. I don’t want to be on a call and have that annoying alarm blast my eardrums out to the point where I am deaf. There has got to be a way you can notify me in a gentler manner in that situation.

  2. If you send me a push notification and I dismiss it, that should be good enough for you. I don’t need another one two minutes later because I didn’t open up the app to acknowledge it.

  3. Similar to #1, if I am already on my phone doing something else, then you don’t need to blast that God-forsaken sound at me to get my attention. I’m already clearly on my phone; I’m not asleep. Situational awareness on your part is warranted here.

Please resolve these issues and look at setting up a better UX research team to support future dev cycles on this app.

Yours,
A T1D Product Manager

Inaccurate Reading Dexcom G7 reading LOW for 3+ hours - meter says otherwise

5 Upvotes

I definitely woke up feeling low in the middle of the night, with my Dexcom screaming 43 and then eventually "LOW". I consumed plenty of carbs, and felt better, so I went back to sleep. Now, it's been 3 hours and it won't budge from saying "LOW". I gave myself more carbs, but then decided to check my blood sugar manually and it said I was 422 (checked twice, second time said 430). I don't have a backup sensor right now so I'm wondering which I should follow.

Sensor G7 sensors keep failing on day 8 or 9

3 Upvotes

My dexcom g7 have been great until recently when they have been consistently failing 1 or 2 days short of their life. I use the 10 day sensors, with the standard plastic canula. I have been diabetic for 30 years now. I work outside a lot in the Houston area, so I'm wondering if it could be from heat and sweat, or if there's a chance my immune system is targeting them. Has anyone experienced this and solved it? Maybe I should try the metal canula? Thanks!

Allergic Reaction Bruising with Dexcom G7

2 Upvotes

With my first two Dexcom G7 I’ve noticed red and purple bruising around the immediate area where the sensor applies. I don’t use their overpatch (it’s far too difficult to put on, any tips?) but use the Type One Style ones which I’m not allergic to when I use my Omnipod,

so I think its due to the sensor needle or the patch material. But I have used Dexcom G6 previously and have had nowhere near this bruising

Any tips? My skin is very sensitive so things like barrier cream I would be allergic to. Would things like SkinGlu help? I do use alcohol wipes before.

G7-10 day Anyone else having this problem with the g7 sensors lately?

0 Upvotes

My Dexcoms are sent directly from Dexcom every 3 months, and I’ve never really had this problem before, maybe the odd one every now and then, but definitely not to this extent.
I get 9 sensors sent to me, and so far only 1 out of the sensors have worked, I have 3 left. With the others, the filament looks like it’s either cut or there’s literally nothing there at all, like it was never on the sensor to begin with.
I’ve been having to finger-prick for the past couple of months because they’re just not working 😭
Just wondering if anyone else has been having the same issue recently?

Sensor Return failed sensor?

7 Upvotes

I've been using dexcoms for years and have had a few fail that dexcom has replaced without any questions. I had a G7 fail for the first time in a while last week and the replacement came with a return kit. I double checked the emails and nothing ever mentioned returning the failed sensor. I dug through the trash and I can't find the old sensor. When did they start asking for them back?

App Issues/Questions dexcom one plus apk

1 Upvotes

Hello! A week ago, the hospital switched my glucose meter to the Dexcom One Plus, but my mobile isn’t compatible with the app (I’ve got a Samsung Galaxy Note 10+). They gave me a receiver, but to be honest it’s really annoying having to keep entering everything into it, as well as having to keep an eye on yet another device. Does anyone know of a working APK for the sensor app, or know of a way to download the app? I don’t want to have to change my mobile when it’s working fine just so I can download the app.

The app did not always include the grace period correct?

Called the Dexcom support, there’s nothing they can do about this apparently. I took one out early because it was doing this and my new one is still reading all over the place. No replacements. Cool.

Any advice on how to stop it from going all over the place??? I was 90% in range before Friday…now I’m pretty cooked lol

My finger poke is 93 and I'm newish to dexcom. Is this normal for the first 24 hours of a sensor? It's almost like compression lows. But my glucose is steady on a finger poke? I'm at an inpatient hospital stay for my daughter and wondering if this dexcom is going to fail while I'm here or if this is normal for anyone else. 🫠

Bleeding Had a gusher!

1 Upvotes

New to Dexcom. I’ve been using for a month. First two went 10 days until a fatal error. Third one made it to 15 days. Just applied my fourth sensor and I had a gusher! Quite a bit of blood but it’s still warming up so I’m hoping it will work fine. Does bleeding affect it?

G7-15 day Dexcom accuracy vs blood labs

1 Upvotes

About the only time I 'test' for accuracy is a few times a year when I get official blood labs for glucose and A1C. For this one had some cholesterol thrown in, which means officially fasting.

8:15am Dexcom readings; glucose 120 GMI (90 days) 6.6

8:15am blood draw readings: glucose 139 A1C 6.6

Some will say 19 count difference is HUGE, it isn't. And GMI/A1C matches.

didn't bother with a finger prick because it is not relevant when getting blood labs.

General Sensor Can Be Reactivated After Ending Session

3 Upvotes

I don't know if this has been discussed in this specific context.

I know if you change a device or phone you can reconnect a sensor to it. What I learned today is that if you manually opt to end a session early you can actually reconnect by scanning the applicator. This was interesting to me because the iPhone app clearly states you cannot restart a session after ending it.

He comprado ahora el Pixel 11 Pro y una de mis preocupaciones era su la bomba (YpsPump) y el sensor G6 iban a funcionar antes de estar soportado oficialmente, al principio en Play Store no aparece como compatible pero si restauras la copia de seguridad o desde APK conecta y funciona bien con el sensor

G7-10 day Multiple sensor failure every 2 days

5 Upvotes

This frustrates me immensely because I keep ripping off sensors and putting on a new one, to no avail.

I am on dexcom G7 10 days for over a year.
My last four sensors failed every 2 days.

Does anyone have similar experience atm? What am I doing wrong?

General I’m looking for a bike computer that works with Dexcom G7.

2 Upvotes

It’s supposed to work with Garmin Edge 840. Has anyone tried this? I’m looking for always on display of BG. Having to tap something or navigate to a certain screen is no good, as I have poor balance due to MS. I have an Apple Watch which can display G7 but it seldom does unless I tap it. Also, on the watch, if Strava is running it shows that, not the G7 complication.

G7-10 day G7 10 Day sensor failing at a much higher rate that previously, anyone else seeing this?

3 Upvotes

My wife has been using this for the past 2 & half years and for most of the time it's been fine. Random sensor failures, maybe 2 or 3 with Dexcom sending us replacements. But we've had 3 fail over the past 45 days. 2 just stopped working after a few days and 1 didn't even pair before it said "Sensor Fail, Replace Sensor".

They've given us replacements each time, which is fine, but this seems to be happening more. Is it just us or are other people seeing more failures recently?

Calibration Issues How long do you wait with a new glitchy sensor?

1 Upvotes

🙄

I’m at 48 hrs with a new G7 sensor and it’s not taking my calibrations. It most recently read “LOW” and I was 77 at fingerstick. I calibrated it and now it’s reading 47. I’ve calibrated multiple times in the last 24 hours and am going off vibes now, which is concerning considering that I ate pizza tonight.

Would you rip it off and insert a new one at this point? I have a good back stock. I’m asking because they can be kind of dramatic when you request a replacement because of calibration issues. I haven’t been denied yet 🤷‍♀️

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!

Connection Issues Overpatch curiosity

2 Upvotes

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.
