Hello.

I recently lost my insurance. Employer is going out of business & my new employer doesn’t offer coverage. I don’t qualify for state assistance.

I’m T1 diabetic & could barely afford my insulin this month. I am out of sensors, G7. Does anyone know of any places to get some replacements or samples? I have already applied for the assistance program through dexcom but they told me today that I wouldn’t be receiving the supplies for 30 days due to low stock.

My insurance denied the Dexcom G7 15-day sensor. Of course, I had to get prior authorization as usual since I'm Type 2. I only get approved for 1 year than redo the process each year for old insurance

This isn't the first time I’ve had to get prior authorization, as I usually get a one-year approval. This was also my first time switching to Costco and my new insurance; now, I’m only paying $50 for a three-month supply. CVS was a total rip-off—I was paying around $230 Libre for three months there. I’m not sure if the big discount is coming from my insurance or Costco, but even my other medications are cheaper at Costco than at CVS. I really hate CVS for their rip-off prices.
I really thankfully for my Doctor calling the insurance to get prior authorization. my old doctors never call to try to get prior authorization. I was deny so many times before

anybody get discounts from Costco ? it's just new insurance ?

Long story short, my entire 90 day supply of G7s got thrown out and they are gone. There is no way to retrieve them. I know I’m stupid, I know it’s insane, please don’t tell me that, I know

I need to figure out what to do. Is my only option paying for them over the counter?

Coming from G6 to G7, the G7 app made some changes to how it’s calculating Time in Target

Daytime I use 3.9-7.8 mmol/l

Nighttime I target 3.9-10 mmol/l

The G6 app measured my overall time in target with 3.9-10 mmol/l regardless of the lower daytime setting.

The G7 app has chosen to measure me against the lower 3.9-7.8 mmol/l and my time in target cratered.

Would you leave the G7 as is or have it calculate with the broader range like the G6 was?

My mom is 85 years old, Type 2, in assisted living, and she uses a DexCom G7. She used the G6 and we always put it on her abdomen because being her age, she doesn't have muscle tone or much fat at all in her arms, and so her upper arms are, shall we say, "flappy" (she's not online, I think she would call them flappy too). Her abdomen is honestly ideal, but we just haven't made the switch because of 1) the FDA recs, and 2) she usually gets her nightly basaglar injection in her abdomen now. However, she has a tendency to sleep on her right, and it will sometimes fall off, or we will lose the signal for a bit (I keep track through the Follow app). She's due to change her sensor today and I'm thinking do the abdomen this time to see if that's better. Would appreciate some advice!

I have a weird experience with food , I realized that All purpose flour doesn’t affect that much my sugar , ofcorrse there is a spike but compared to whole wheat flour , rice flour it’s nothing , I can eat bread and pasta and still my numbers are under 200 but if I touch whole wheat flour or rice or rice flour , it crosses 300 . Do you guys also have this weird thing . I can’t make sense of it , I thought whole wheat flour or rice flour is better than all purpose flour .

Just put it on, and it bled like crazy. Wiped it and it just bled out again - I do use the insertion device to hold it down for a minute for adhesion, then put on the green cover and use the insertion device to press down again for another minute, but its never bled out even a little before. Anyone seen this before - is this thing going to work at all now?

I started on the G7 back in November 2025 following diagnosis. They worked great up until around beginning of March this year.

Since then, I’ve been unable to get more than five days out of any one G7.

The sensors will work great out of the box, but will begin to fall apart after the ~48 hour mark. Failures follow a remarkably-consistent pattern of: erratic readings that quickly progress to chronic under reading, before failing with either a ‘brief sensor issue’ for >3hrs, or an ‘LOW’ reading that will not budge.

Some fail earlier, some fail later, but the average time to failure is probably around 3 days.

I’ve noticed that I tend to have inflammation at the insertion site upon removal. In some cases there is visible pus at the site, despite using alcohol spray + an alcohol wipe before insertion.

I’m beginning to worry that my immune system basically precludes me from using CGMs, which is a terrifying thought, considering how much nicer life has been with a closed loop pump.

Most of my sensors keep failing at day 6 or day 7, this has been consistently happening for a while now, and I am confused as to what the cause might be.
I wear the sensor on the back of my arm, and am quite thin (192cm, 70kg) so I'm not sure if I would be able to apply it to my stomach?
I'm just tired of filling out the return form, because its a hassle.

Might it also be another problem? The app shows "Brief sensor issue" and then after an hour or two the sensor fails.

I’m traveling to Mexico next week and my current sensor will expire mid trip. If I take a sensor with my will I be able to use it. Mexico is not listed on Dexcom website.

How would the sensor know it’s in Mexico? Through phone app? If so, can I connect it only to tslim pump and be okay?

I put in a new sensor last night around 8pm it kicked on. I usually try to not calibrate in the first 24 hours but sometimes I will if I feel like I have to. When it first kicked on it was off by 20, which is fine. Before bed around 11 it was off by 40 but I left it alone and went to sleep. Woke up in the middle of the night and it was off by 60 so I calibrated it. When I woke up 4 hours later, it was off by 15 so I was feeling good, but now 3 hours later again it’s off by 40. It just seems like it’s not holding my calibration and I’m not sure what to do.
