CGMs & Meters - Why don't the numbers match??

[@bmw328driver]

Thanks for another helpful video. I had heard about several, though far from all, of these factors before. Thanks for a more complete picture of other items to consider! The main one I remember from before was how the interstitial sugar level trails the blood sugar level. Thanks for the explanation reminder of why this is. The best analogy I was told about for it is a roller coaster. The blood sugar level is in the front car going up and down, while the interstitial level is in the back car, following behind.

Dear Danica. I’ve missed your videos! You’ve taught me valuable information in the last few years. I hope your life is happy and hope you post more often! 🙏🧡

I have been most fortunate that the Dexcom CGM and finger sticks are usually spot on accurate. I've had the CGM for over a year. At first I would check the numbers every few days. Before Dexcom I was doing finger sticks 8-10 times a day. Now I don't check at all and I never calibrate. I feel very blessed for it to work so well. Great video, thank you for posting this video.

Where do you have the sensor inserted to get such consistent and accurate readings?

Thank you for another great video, Danica! I’ve been struggling with my diabetes lately. I’ve been binging your videos (new and old) and it’s been helping me get back on track. Thank you for all you do! You look GORGEOUS btw 😊

[@eddiel798]

Thanks for sharing this very important information.

[@ashleylindsey1829]

Danica, I have missed you so much! So glad to see you making videos again. You are so motivating to watch!

[@lindalong8403]

Thanks Danica. Would you consider doing a video on traveling through an airport with Dexcom and Tslim X2 pump? Thank you.

[@DEBRACRANFORD]

I go through this all the time and would like to know also

[@gill6257]

This would be really helpful. My daughter has a school trip booked & hasn't travelled by airplane since diagnosis. We are keen she doesn't miss out or is held back by T1 but anxious

[@catdad1013]

Thank you very much. YOu gave me more info about my CGM then my doctor did.

[@debbief1271]

Thank you for this video. I did not know about the compression factor. Explains why I get more lows at night. I love viewing your videos. Living life with us is so enlightening. ❤

[@johnb4183]

Super interesting / informative , "compression lows" with a CGM that's a first for me .................. Thanks

Engineer speaking. I may have missed it but if you didn’t I want to add If you buy to meters from the manufacturer taking them off the assembly line one right after the other THEY WILL GIV DIFFERENT READINGS Why is this? Because when electronics (or anything else) are made no two are EXACTLY the same. 5his means those resistors inside the Interested Circuit that ais the brains of the meter will cause different results. As engineers we do everything we can to reduce these differences but we CAN NOT eliminate them. Also never forget that as devices age their performance will change Sorry

[@dingdongdaddy589]

They are baseline calibrated, Engineer - choo chooooo!

I have a video topic suggestion. My son has a Tandem T-slim and a Dexcom G6. The tech part of diabetes seems just as hard as the illness itself. The sensor will not talk to the pump right now. We are on the 5th week of spotty readings from the G6. The pump seems to inconsistently deliver. I say that because things were fine and then they went crazy. A needle injection would act as insulin should. Pump boluses did not. Sites were changed multiple times. Sometimes a delivery worked and sometimes it did not. That is always the case with diabetes but this has been extreme. The thing is after a certain amount of time all of our Tandems have done this. Yes we have told them but they don't think it is their pump. However, we are on the 4th in 3 years. and the pattern of time has been the same for when trouble begins. So all that to say, maybe you could address issues that you are aware of with the tech side of diabetes?

I am in complete agreement with this mom’s request. Also, Danica nice to see you are back on-line. I have been offline for the last year as I am happy to say I survived passing out at home with my own complications due to my diabetes. I had a “silent UTI”, as I had no symptoms, other than waking up “delusional” and thus not realizing just how sick I was. My sugars climbed to 1009, but I was found in time to be rushed to the ER and after many days I finally was able to wake back up. I tend to no longer get the body “alerts” as I will explain this as an important “take away” for those dealing with all of these different complications with diabetic “tools” which are supposedly going to help us with managing our diabetes and keeping our blood sugars well controlled. Well, I am a rare Type 1 Brittle Diabetic, as I became diabetic one year after a nearly fatal auto accident. At the time, I was in my early 40’s and so very grateful to have lived a very active life prior to this game changing event in my life after my accident. Once my diagnosis came in we did our best to control my blood sugars with no clue as to why they were simply “all over the place”. Five years forward, I end up in the ICU for six nights with my first case of DKA. I thought I had eaten something bad and had no idea why I could not stop throwing up every 20 minutes for hours, and my body was NOT responding to my insulin. Thus I was told by my own endocrinologist’s nurse, “Get to the ER NOW, as you are likely slipping into DKA and it can turn deadly”. Well, I really had no clue what she meant by DKA. I thought I would just need a little saline for dehydration. Not so. Finally, after this hospital stay I was told to explore whether or not I may have developed a likely complication from all that I had been through, delayed stomach emptying, called Gastroparesis. My doctors were shocked to find that my food was staying in my tummy way too, too long. Now it has been another 13 years and I am dealing with further complications brought on by neuropathies which continue to wreak havoc with my ability to heal and deal with my complex conditions. So I now know these neuropathies are what cause me to end up in the ER with literally - HIGH blood sugars - and which they often find I have some sort of infection and they always come into my room and ask, “Do you really not feel sick”? I would explain, “Nope, other than the fatigue which is about the only feeling I still get when my blood sugars are goofy”. As those with diabetes know fatigue is often a given so it can be hard to recognize just when the fatigue may be trying to “alert” you that you may soon need help. I am now 61, living alone and ever so grateful to have survived. I have been told my full recovery can take up to 2 years. I have tried the devices, and due to adhesions in my belly I am unable to wear my insulin pump as it will not properly communicate with my insulin pump. So I am now in search of seeing whether a Diabetic Alert Dog could be of some further assistance to me so I can continue to be independent and get some since of normalcy back into my life. Last year’s health scare started in March, and I was not sent home to “stay” until early July, 2022. Since then, I have yet to gain back any weight and I now keep close watch on my blood sugars. I will say that DEXCOM technicians finally admitted to me that they were finding “those who may have had abdominal surgeries” may not get the best of readings with their sensor. So thank Danica for sharing these many complications to consider, I had never been told our sensors could be sensitive to the extreme temperatures so this is the BEST news of the day for me to stay aware of as I do live in a place where it can be well over 100 for many months during the summer. I will be sure to be home to bring my sensors inside right away. I wish you and all who watch you the best of luck with finding solutions to this life changing condition. It can be a challenge and I feel for any and all parents who are managing the care for their own child - kudos to each of you truly are their best chance at a well managed life when you can take care of this sooner than later!! Stay strong Danica!!

Sensors are hit and mis with the real numbers and very sensetive for presure water and some medicine..

[@happymark1805]

well some bloodsuggar meters have a tollerance of more than 25%, pretty useless, if you use a 780 pump with the guardian4 sensor they are calibrated out of the box, but not 100% accurate, the accucheck guide link and contour next are the most accurate of blood suggar meters out there, I noticed that when using that combo the readings of the cgm and accucheck guide link are pretty much the same

[@assassin0162]

Why, when there is a large difference between meter and CGM, and you recalibrate your CGM the message is given to try again in 15 minutes after a new finger stick

[@yeahnahbeauty]

Literally my sons cgm says 16.5 right now and finger prick says 12.1 mmol

[@SharpLife4]

Grab a different meter. It likely will also be different

[@dvdv7777]

Both CGMs and fingerprick meters are most accurate in a specific range. 16.5 and 12.1 mmol are well outside of that range. You'd need YSI lab analyzers to get accurate readings when the BG is that high.

[@yeahnahbeauty]

@@dvdv7777 yeah it’s not ideal that range, he’s usually sitting under 10mmol but he has autism too and his emotions really impact his bgl at times, just boom and we’re fighting a high
