don't get me wrong. I do love my Dexcom G7, but let's be real here. It's not all rainbows and butterflies. The G7 also has some issues, and I think it's just as important to talk about some of the downsides of our diabetes tech. Because well, just pretending everything is perfect is kind of a weird way of putting our heads in the sand. So let's talk about it. Let's talk about the five things that I think don't really work when it comes to the Dexcom G7, plus some of the things that I think we can do to well make the G7s suck a little less. Yeah, I'm Crystal from Diabetes Strong, and I've been living with diabetes since 1997. And I've been wearing Dexcom CGMs for quite a few years now. I started out on the Dexcom G5 and then moved over now to the Dexcom G7. I've been using that since early 2023. And as I said upfront in this video, I do love my

Dexcom t7. So, this is in no way a video meant to trash the Dexcom t7, but rather a discussion of some of the things that I think could be improved, okay? The most annoying and maybe most recognized issue with the Dexcom t7 is a frequent signal loss. Signal loss simply means that your Dexcom CGM, so the sensor that's on your body, loses contact with your phone or your receiver, so you're not getting any blood sugar readings, which is really unfortunate because obviously getting blood sugar readings is the only real reason why we wear a CGM. I've experienced sensor loss with the Dexcom t7 in situations where my previous Dexcom models were just fine. So, examples would be having a sensor on my left arm and my receiver or my phone on my right side, having my phone in my purse, or even in my back pocket. So, Dexcom does recognize this as an issue, and their solution is simply do not put your phone or receiver on the other side of the body as your sensor. Well, I think

that's a little silly. In my experience, the signal usually comes back fairly quickly. I've only had a handful of sensors where it was a persistent problem, and usually that would be towards the end of the 10-day sense of Lifetime. But regardless of why and when and how long, signal loss is very frustrating. I've seen a few theories float around online on why this is happening, one being that people speculate that the Bluetooth connection isn't as strong as it was in previous models. That sounds about right to me without me knowing the exact facts on that or being an engineer. According to taxcom, um, signal loss can have a few different reasons, and they also offer some solutions. Of course, you could be in a situation where you're just too far away from your receiver, um, but that would also been an issue for previous models as all of them require you to be within 20 feet of your receiver, so I guess that's an easy fix if you leave your phone at home. Don't do

that then you'll get lost signal. Other things they also mentioned is that you need to have your Dexcom app open. Makes sense. Um, it doesn't mean that your phone has to be open. You need to be able to see the Dexcom app all the time, but you can't close it down on your phone. Second, they say don't use low power mode, which was a little bit interesting to me because I didn't realize this. So low power mode is when you put your phone in low power mode so it preserves battery. Apparently, that doesn't really work with the Dexcom t7. And then I do appreciate that very low-tech solution to signal loss, and that is simply to turn off your device and turn it back on. Very innovative. [Music] Yes, signal loss can be super frustrating, but I've also found that a good portion of my Dexcom t7 sensors are super bunkers inaccurate the first 24 hours. So one good debate: what is most frustrating, signal loss or bunkers blood sugar readings.

probably Bunker's blood sugar readings all ctms regardless of Brandon model could be expected to have some level of inaccuracy the first 24 hours as a sensor just to the body at this point. I don't have a side-by-side comparison of Dexcom t7 numbers in Dexcom T6 numbers. I am working on that though so remember to subscribe to my channel if you want to check out that content but it's more of a feel right now. It feels like more of my Dexcom t7s are inaccurate than previous models so there's only really one way of knowing if your sensor is inaccurate and that's by doing a finger stick so that's what I do especially those first 24 hours. So I do finger sticks I do spot checks and I also really try to be in tune with how I feel so if the Dexcom shows a weird high blood sugar well I don't just correct that I do a finger stick to see if it's actually that high same thing with lows and

usually after those first 24 hours tend to become accurate enough that I start to trust it, and I don't do finger sticks as often. With previous Dexcom models, you could insert the sensor 24 hours or more before you started it, thereby letting the sensor adjust to the body, making it more accurate for those first 24 hours. Um, you can still do that with the Dexcom G7. However, once inserted, even if you haven't started in the app, once inserted, the lifetime of this sensor starts. So for me, that's not really worth it. I don't have enough sensors that are wonky that I think it's worth losing 24 hours. [Music] Another frustrating thing about Dexcom G7 are the compression lows. So compression low is a fake low blood sugar that you get when you put pressure on the sensor. For example, when you're sleeping. My guess is that the real issue if you wear a Dexcom G7 on your arm, which is what it's FDA approved for. It's only FDA approved for wear on the arm.

don't want to make a side note here, and that is that it's CE marked. And it's the same sensor, but it has a CE Mark for work both on the arm as well as on the stomach. So, you can obviously do whatever you want with that information. I'm not telling you to go off label, but that's what the CE Mark says. And I can tell you that I've been wearing my Dexcom G7 on my stomach most of the summer, and for me, it works really well there, maybe even better than on the arm. So, how do you know if it's a false low blood sugar? Well, it's usually fairly easy to see. Often, if you look at your Dexcom graph, you'll see your blood sugar sort of plotting along, maybe in a flat line, and then all of a sudden, bam, you'll get a low blood sugar reading, like urgent low, out of the blue kind of thing. No downward slope, no nothing, just an urgent low. That usually tells you that this is a compression low, and it can be

problematic. So, one thing is being woken up for some in the middle of the night with an urgent lower alarm that can be frustrating. I'd rather sleep than getting false alarms, but it can also be an issue if you don't check your graph and you don't recognize that it's a false low reading and you treat it with glucose, which can lead to high blood sugars later. [Music] Another kind of weird issue that can potentially be real problematic is that choppy or even jumpy Dexcom graph. I've come to conclude that the Dexcom t7 self-adjusts to blood sugars more frequently, meaning that if it thinks it's inaccurate, it'll make sort of a Here and Now adjustment, which in theory sounds great. We want more accurate sensors, but unfortunately, it can also lead to a bit more unpredictable readings and well, wrong readings. Let me explain. I'll sometimes see a sharp increase in blood sugars from these self-adjustments, and I have to be really careful not to just blindly react to

them as often. The sensor will self-adjust, and the blood sugar line will come down to where it was before that jump. And since Dexcom t7 only updates every five minutes, it can be worth waiting 10 minutes plus before reacting to abrupt blood sugar changes. Or of course, I could just do a finger stick to check. As for the historic blood sugar graphs being a little bit more choppy than in previous models, I'm not sure it matters a whole lot. It might not be super aesthetically pleasing, but it probably doesn't matter for historic data analysis. [Music] The final thing that's kind of a bummer but probably done deliberately is that the Dexcom t7 cannot be restarted. Yes, you get a 12-hour grace period, which is awesome, but if you, for example, run out of sensors or you can't afford to buy a new one, unfortunately, you cannot restart the Dexcom t7 sensor as you could with the Dexcom D6. I get it from a business perspective. They don't want you

to use a sensor longer than it's actually proved for, and there might also be some heightened risk of infection if you wear it longer than the 10 days, but it's really a bummer because I know that this means that for some people, as ctm a Dexcom CDM specifically, is just going to be too expensive. So what do you think? Do you have anything to add to my short list of things that don't work with dexcomp D7, or maybe you love it? That's totally cool. I actually plan on doing a video with five things that I love about my Dexcom G7. So regardless, please leave me a comment down below. Let me know what you think about the device, and if you like this video, please give it a like below and subscribe to my channel. Remember to turn on notifications, that is that little bell, that will inform you whenever I post new content. Thank you so much for watching, and I'll see you next time. [Music]

덱스콤 T7의 단점: 현실적인 논의

Dexcom T7은 잦은 신호 손실로 인해 혈당 측정값이 중단되는 등 몇 가지 문제가 있습니다.

신호 손실 문제에 대한 덱스콤의 해결책은 휴대폰이나 수신기를 센서의 반대편에 두지 않는 것이지만, 이것이 항상 실용적인 것은 아닙니다.

Diabetes Strong의 Crystal이 수년간의 Dexcom CGM 사용 경험을 바탕으로 G7의 사용 환경을 개선할 수 있는 개선점을 제안합니다.

Dexcom T7 센서의 신호 손실 문제 해결

Dexcom T7 센서의 신호 손실은 실망스러울 수 있지만 몇 가지 일반적인 원인과 해결책이 있습니다.

블루투스 연결이 약하거나 수신기와 너무 멀리 떨어져 있거나 Dexcom 앱이 닫혀 있기 때문일 수 있습니다.

휴대폰에서 저전력 모드를 사용하는 것도 덱스콤 T7과 호환되지 않습니다.

또한 장치를 껐다 켜는 것도 신호 손실에 대한 효과적인 저기술 솔루션이 될 수 있습니다.

덱스콤 T7 혈당 측정기의 도전과 좌절

Dexcom T7은 처음 24시간 동안 부정확할 수 있으며, 이로 인해 자주 핑거 스틱과 현장 점검이 필요할 수 있습니다.

이전 모델과 달리 T7의 센서 수명은 삽입 후 즉시 시작되므로 시작하기 전에 신체에 적응할 수 있는 옵션이 없습니다.

센서에 가해지는 압력으로 인해 저혈당 수치가 거짓으로 표시되는 압박 저하는 특히 FDA 승인을 받은 T7을 팔에 착용할 때 흔히 발생하는 불편한 점입니다.

CE 마크가 Dexcom G7 센서 배치에 미치는 영향

CE 마크는 팔과 배에 모두 사용할 수 있는 Dexcom G7 센서를 허용하여 사용자에게 유연성을 제공합니다.

갑작스럽고 설명할 수 없는 저혈당 수치는 센서 배치로 인해 발생할 수 있는 압박 부족을 나타낼 수 있습니다.

정확도 향상을 위한 G7의 자가 조정 기능으로 인해 예측할 수 없는 부정확한 혈당 수치가 나올 수 있으며, 이는 사용자에게 잠재적인 어려움을 초래할 수 있습니다.

덱스콤 G7 연속혈당측정기의 제한점

덱스콤 G7은 자체적으로 조정될 수 있으므로 급격한 혈당 변화에 반응할 때는 주의가 필요합니다.

과거 혈당 그래프가 고르지 않지만 데이터 분석에는 큰 영향을 미치지 않을 수 있습니다.

Dexcom G6와 달리 G7 센서는 재시작할 수 없으므로 일부 사용자에게는 너무 비쌀 수 있습니다.
