CGM PROBLEMS!!!

In Response said:
How do you think we survived for decades with finger pricking?
We we’re not pricking all day long. We used how our body felt to recognise hypos. This is important even with CGMs because, as you have seen, technology fails.
Do not rely on the tech. Make sure your body is the best indicator of highs and lows.

I’ll never know how people survived for decades! I only prick before meals. In the morning and before bed! That is enough! You don’t always feel symptoms of hypos though! You could be having one before you even realise!

personally, I have symptoms if my bg is below 4, and a coma occurs at 0.8. This is not just weakness, it is a very strong tremor throughout the body and visual impairment

Well everyone is different! I hope I don’t EVER go into one of those!!
 
Also don't calibrate too often. Give it a few hours at least between calibrations. Try activating the sensor as soon as it's applied. I know letting it soak works well for some people, but for me I get no benefit.

I only ever calibrate when I feel the need to. Like this morning CGM was lower than usual about 5 something when I woke up. Went downstairs did a finger prick and CGM was way off!! BG meter was saying 9.2!!
 
You can put in a support request online to Dexcom. You don’t need to phone them up. Looks like you need to replace the sensor.

You might want to find which locations work best for other T1 users of the Dexcom One or G6.

Just be careful. Add in a compression low, foot on floor/dawn phenomena, a shower etc etc and the time lag between the sensor reading interstitial fluid to a finger prick blood and things may not be as far out as first appears.

I know. That’s what I do when I have an issue! I am just SICK of contacting them every time something goes wrong! They are probably sick of hearing from me too! What would you put for the issue with the sensor? IMG_3298.jpeg

This is NOT the time to calibrate.
Given the known limitations of CGMs, the time to calibrate is when your BG is stable (not rising or falling), when there are no external events (recent food, bolus insulin still active, exercise, stress, etc) which could change the stability and when your BG is between about 5 and 10.
Calibrating, for example, when the CGM when it is reporting a compression low will cause all future readings to be too high.
I always check my BG with a finger prick before going to bed, at least 4 hours after my last meal and last bolus and exercise. If my BG is "in range", I will calibrate my sensor. This allows me to make minor adjustments every evening and gives me confidence through the night.

I haven’t calibrated NOW!! This was this morning!!

I NEVER calibrate when my BG is rising or falling only ever when it is steady!

I would use “My CGM values appear to be inaccurate”. You may be sleeping on your sensor which is causing all the issues you have with Dexcom and Libre CGMs. See …

I don’t seem to think the issue this time is with me sleeping on the sensor. It’s been working perfectly fine up until this morning!

OK, I’ve seen something like this on a colleague’s kid’s Dexcom & he was BG testing in the 20s.
The kid’s mother knew there was something wrong the DSNs said go with the Dexy..
the Dad came to me at work about it. (Friction at home.) & I had to tell him his partners’s suspicions are correct..
I felt sorry for the guy. & the kid..

They’d for some reason were told to place the sensor on the toddler’s upper buttock?

How far out is your readings…?

This is the Dexcom official placement of sensors for the Dexcom One … https://www.dexcom.com/en-GB/faqs/where-do-i-insert-my-dexcom-one-sensor

Age 2-17 you can place on upper buttock.
Ages 2+ you can use abdomen or back of upper arm.
 
Using the g7 I was told not to calibrate for the first 24 hours and to accept that first 24 hours may be inaccurate, as the body's reaction to a newly inserted sensor may make it read low. Hence I try not to go to bed with a newly inserted sensor. I try to insert my new g7 when the grace period for old one starts. That way it's bedded in for 12 hours when I change over the sensor. You then get to see readings for both sensors on your phone for that grace period, and about half the time the new sensor is very erratic for the first few hours.

Disclaimer. That's me and my body and the g7, gONE+ may be slightly different and people's bodies also react differently.

The most annoying thing for me is when I finally start up the new sensor and it fails on startup, so I lose the benefit of pre inserting it.

However bad the tech it's better than glucometers alone ( for me) though I am old enough to remember the days before glucometers when you had to test your urine with a tablet and drops of urine in a test tube. We kept our bgs much higher then, had fixed doses of insulin and carbs, and T1 diabetics had much lower life expectancies than they do now.
