‘DexCom’ Stock Deserves To Be Punished Given That Their ‘G7 Sensor’ Is Remarkably Inaccurate.

I have worn eight (8) Dexcom G7 sensors — for a total of around 75 days. It is NOT the full 80 you would expect (i.e., 10-day lifespan x 8) because I threw away a couple BEFORE they expired because they were so, so, so inaccurate. There is NO point, whatsoever, of wearing an inaccurate blood glucose monitor. Actually it is harmful — even DANGEROUS. You are being given FAKE RESULTS. What the G7 reports is NOT your actual blood glucose level. Much of the time it is just a RANDOM NUMBER.

I just couldn’t believe HOW INACCURATE the readings were. They were bad. Many times they were not even in the same ballpark. Crazy. Stupid. DANGEROUS. Harmful. Should NOT be allowed. I gave up on the G7. Will never get a DexCom product again. I spent HOURS calling and talking to their support. I bought 3 sensors (for $320 of my OWN money (since it was not covered by insurance) & DexCom support sent me FIVE (5) as replacements because they ‘acknowledged’ that I had DUFF sensors. That is how I ended up with 8 sensors. Dexcom has all my data & knows they screwed up. Hence the 5 free sensors.

You know that old chestnut how a totally broken watch, that doesn’t run, is better than a watch which is 1 second too slow/fast BECAUSE the broken watch AT LEAST shows the correct time TWICE a DAY whereas the slightly inaccurate one NEVER (ever) shows the right time. That is the story with the DexCom G7. Much of the time it just generates garbage results.

Please be warned.

“Dexcom’s” ‘National Diabetes Awareness Month’ Message Disingenuous And Insulting.

I can ONLY talk about the ‘Dexcom G7‘
— & I was NOT IMPRESSED.

I plan, soon, to do a whole series of posts about how UNHAPPY & DISAPPOINTED I was with the Dexcom G7 — that I wore, 24×7, for a month.

I would not bother with a G7 again.

It is possible the Dexcom G6 is more accurate and reliable. IF I ever go with Dexcom it will be with the G6.

Dexcom is just EXPLOITING us patients. I am not impressed with them.

So this message I got, via e-mail today, did NOT make me happy.

As far as I am concerned the Dexcom G7, like the ‘POGO‘, is NOT ready for prime time.

‘POGO’ On-The-Go Blood Glucose Monitor Is Way Inaccurate & Fails To Register Way Too Often.

I TESTED mine, TWICE, using the ‘control solution’ they sent me.
Still reads low — consistently.

The POGO was a crushing disappointment.

I, through PayPal, got a FULL REFUND!

Loved, loved, loved the CONCEPT. All-in-one glucose meter. No fuss, INSTANT testing.

But, it proved to be crushingly disappointing. Consistently gave low, VERY LOW — crazy LOW readings. Per its readings I should not have been standing.

I was wearing a ‘Dexcom G7‘ at the time. The Dexcom G7 wasn’t that great either, but the readings were more believable. Yes, I checked them both with a normal BG meter. The POGO was way low.

I called them. They sent me two batches of CONTROL SOLUTION. I used them both. They said the POGO was within ‘range’. NOT SO. NOT SO.

Well, I got my money back — so I really can’t complain MUCH. It is just that I am disappointed. I hate the hassle of using a standard meter. I don’t have the time or patience. I want to get it done quickly.

Well, it is NOT the POGO — yet!

Maybe they will get it right EVENTUALLY.

I offered to work with them — for FREE. They were NOT interested.

I can now understand why they PULLED their IPO from the market. They probably knew that they would face Class Action Lawsuits.

I am just sharing this with YOU so you don’t get misled.

‘Dexcom G7’ APP Crashes With ‘Android 14’ — Whenever You Touch The Detailed Graph To Get A Reading!

I called Dexcom support (which is responsive & TRIES HARD TO HELP) yesterday to report THIS problem PLUS two (2) others.

They CONFIRMED that the G7 ‘Android’ APP is only supported UP TO Android 13.

APP works on Android 14 as long as you don’t want to go back and check you values.

As soon as you touch the expanded graph, in horizontal view, as you are supposed to do — the APP crashes. So, now with Android 14 you can get the individual readings off the APP.

Dexcom is going to, of course, look into it.

‘Dexcom’ Sent Me A Replacement ‘G7 Sensor’ (Continuous Glucose Monitor (CGM)) That I Didn’t Need, Nor Asked For –> I Am Chuffed.

I am NOT COMPLAINING. I am chuffed. Each G7 Sensor, retail, is ~$100. So, WOW.

I get another 10-days of Dexcom G7 CGM. That is cool.

I did NOT ask for this replacement!

This, ALAS, is Dexcom support’s poor understanding of the issues. They, as I said in a prior post, are helpful BUT clueless.

I had called to ask why I was NOT getting their equivalent of an ‘a1C‘ — called ‘GMI‘.

They just could NOT understand that …

They had to first go look up what GMI was!

That wasn’t good. I knew what GMI was.

Then they latched on that I had suffered a SIGNAL LOSS earlier that day. MY FAULT. I told them that. I had walked away from my phone. I managed to reestablish the signal.

But, they would NOT let it go.

That is why they sent me this replacement. Because of that signal loss — which was my fault!

C’est la vie.

My Take On The ‘Dexcom G7’ Continuous Glucose Monitor (CGM) After Wearing One For 4-Days.

Wow. Yes, I am getting numbers. Some good, some scary & some unexpected. But, right now I have NO IDEA if these numbers are correct. I need to get another tester. I will do that because I have plans to wear a CGM for more than 1-month right now. The time will come when I will have to wear one — for LIFE. Hopefully still a few months down the road.

Real glad I got this. I have NO IDEA how my glucose levels fluctuated. Now, after 4 days I have a much better idea. I now even no what to expect.

BIG thing is that I have make sure the numbers are meaningful. Otherwise just a random number generator. So, that is the next step.

So, the chart above tells you all you really need to know.

I will provide regular updates. OK?

I Am Wearing A ‘Dexcom G7’ Continuous Glucose Monitor (CGM) — NO, I Am NOT Diabetic (YET).

I am NOT diabetic AS YET — but I just crept into
the prediabetes range.

That was the whole point of getting the ‘Dexcom G7‘ CGM with a permanent patch that monitors glucose level 24×7 at 5-minute intervals.

I have known all my life that I am prone to become diabetic. We has a race are predisposed to it. I have spent a better part of life trying to DELAY IT.

It is NOT if, but when — so, I just want to TRY and keep on pushing that when down the road.

Hence, all my walking and low-carb diet. But, my A1c keeps creeping up, year after year. It finally crossed over to the prediabetes range.

I am just glad that I managed to DELAY that till I was past 70.

Now, the goal is to stay PREDIABETIC as long as possible.

I have NO DESIRE, whatsoever, for longevity. So, IF I can push it down the road a few more years, I will be content.

I had seen the Dexcom products years ago.

I wanted a CGM to BEGIN WITH. I want to UNDERSTAND what is happening within my body.

My insurance wouldn’t pay for it BECAUSE I am not diabetic. Plus, NONE cover the NEW & quite expensive G7.

I bought 3 patches/sensors. Each works for 10-days. So, I have 30-day coverage. Not sure I will go beyond that. It is expensive & the APP isn’t that great. I might just go with pin prick readers –> with better APPS. But, that is down the road.

I have learnt a lot already.

I will keep you posted.

Interesting stuff ….

A year ago I went BACK to using mouthwash — (at least) TWICE a day.

My A1c has GONE UP!

Yes, there are OTHER FACTORS TOO. I am fully aware of that. But, as with other changes, I ditched the mouthwash.
