Dexcom G7 – 5 Things That Don’t Work

Hello. Yes I have all of this issues with my Dexcom G7 but I also LOVE IT😊 For me it has been a 360 degree turn, only when in doubt I just measure my glucose. Thank you for all your videos, I have learned a lot from watching you, I was also diagnosed the same year as you. God bless you. A big hug from New York!🗽

I have been a Dexcom G6 and now a G7 user. My biggest problem is waking me up in the middle of the night with low sugar alerts. I draw blood and it may be 140 and the G7 says going down below 70. I do not trust the G7 numbers and still draw blood 3 to 5 times a day. The G6 wasn't any better. Today I received another shipment of G7 sensors. The first one I placed on my arm would not connect after many hours. I called Dexcom and they told me to remove it and try another sensor. This one started right away. I calibrated the new one. This morning the Dexcom said my sugar was 110. When I drew blood my reading was 79. Now for a reading of 110 I am to use 10 units of Humalog. This is why I don't trust Dexcom. Be safe.

I’ve had my G7 for 3 months now and it is working fine. I have had one failed sensor, 2loss signals, and one recalibration. I was on the G6 for 2 years. I had a lot of issues with the G6 sensors. Several failures and lots of recalibrations. I am applying the sensor on my abdomen as I was with the G6. I thought I would let you know of my experience with the G7 so far. Keep up the good work!!

I am an engineer and Dexcom is using weaker transceivers. BlueTooth has an effective range of around 30 feet. This range can be lowered if you have hard barriers such as walls in the way but the new Dexcoms are weaker. I saw this starting in the early 2020s with my Dexcom G6. You should be able to have a good signal with the receiver in you back pocket. That's just poor manufacture or engineering.

I’ve been wearing the G7 for a little over a month and I love how it has changed my relationship with food. I agree, the 1st 24 hours of lows and alerts are annoying. I’ve also had experience with skin rashes once I remove the patch. But overall, the small annoyances are nothing compared to the goals of keeping my blood sugars within range. Thanks for all the essential info on your channel! 💗

Hello!!! On my second G7 sensor now, the first one had two signal losses, within one hour and my phone was on my lap, I was in Church when it went off, the pone was under 24" from the sensor at the time. I contacted Dexcom and they promptly sent me another Sensor with a Return Kit.. Ya, I deal with all those things, getting used to it. I like it though. Thanks for your channel!! I just had my first anniversary of being diagnosed as a type 2. Your channel has been so useful.

I'm T2 and on my 10th sensor. What you experienced is pretty spot on with what I have experienced! When I was waiting for my very first shipment, I started watching your videos and I found out so much thanks to you!

Thank you for replying to my questions concerning synchronizing my InPen and the Dexcom G7. Not as easy as the G6 but I now have everything working. Really enjoy your posts. Thanks again, Robert S.

I am a technologist with some experience is designing wearables. I think to increase battery life of sensor, G7 designers may have reduced power into bluetooth chip that could be cause for signal loss.

I will be receiving my first G7 tomorrow, thus transitioning from my beloved G6. Thank you for this really informative video with the 5 tips that eliminate having to figure out the new quirks on my own! Glad to know I can still wear the sensor on my stomach as I sleep on my side and don't want unnecessary compression alarms from arm sensor placement,

I'm type1 diabetic and I was on the G6 and now I am on G7 which is a huge difference. I loved the G6 more because it's more accurate and constant. Everything you've experienced is exactly my experience. I am going to try using it on my stomach to see if it differs in staying connected Thanks for the update. I have liked and subscribed to your channel. Looking forward to more updates

I found this video very helpful. I just started with the devise and did not realize about false readings in the first 25 hours. I did have some warnings and needed to wait rather than reacting too quickly.

Love my G7. I find that quite a few sensors fail after insertion. Dexcom are very good about replacing them. The issues that you point out are spot on.

You helped me much more than my 3 calls to Dexcom customer support re: signal strength and accuracy. You nailed it. Thank you! I’m a new subscriber.

Thanks for making this video and sharing it with us. I agree on everything you said. Some of my sessions there is no issues at all, some not so much, but all in all. I love my dexcom g7.

Just wish they would prolong the life of the G7 for 14 days

My wife has been a g5,mG6, and now a G7 for sometime. My insurance has finally approved me using it as well. I have been a Type 2 for nearly 40 years. My wife was complaining about on the arm and tried the abdomen but Dexcom does not recommend this unless doctor approval. The first couple of placements on my arm were more ink the armpit area. Yes, I would get "Loss of signal" especially at night. I finally started putting it om the outside of may arm as recommended. No loss of signal issues. However both extensive paper tape or Micropore tape would start to loosen up after a few days. I purchased a 50 pc pack of 4"x5" transparent adhesive dressings, the kind that are used over IV sites to hold the assembly in place. This is placed over the G7 Overpatch without any additional tape used. This works great and was approved by the Dexcom support staff. Bye the way, if a sensor fails ,or has the be removed short of its 10 day usage, contact Dexcom for a free replacement as well as spare overarches. Keep the old unit as they will require the serial number for a free replacement. Greg Locke

Thank you for this video. I just started the dexter COM seven which is my 1st m meter. So far everything you said is spot on. Thanks again.

Good points here! Been wearing a G6 for about 2 years now. Same sensor inaccuracy issues during 1st 24 hours and last 24 hours. Even after numerous calibrations.

Hi Christel. Thank you for your review of the Dexcom G7. I don't know whether it makes a difference or not, but I use the receiver. I am new to the CGM since Springtime and didn't realize that readings could be inaccurate. I've been trusting it. Now that you mention it, there have been times in the middle of the night I get woken up to alarms of low blood sugar...take glucose tablets...wake up in the morning with high blood sugars. I didn't realize that there could be a false low alarm. Sometimes when sleeping the alarm has gone off telling me that signal is lost, when I am right next to the sensor which is on my night table. Perhaps I was laying on the arm that has the sensor on it. You are very sharp, very knowledgeable, and always offer great tips and ideas. I've learned a lot from you and I am so grateful. I will take better note of my Dexcom G7 from now on. I didn't know. Thank you so much for this valuable information!!! You're the best!!!
