Bloody Dexcom Sensors: No Go or A-Okay?

This post was originally published on Hugging the Cactus on February 18, 2019. I’m re-posting it today with some updates because I recently noticed this post gets a LOT of clicks – this topic is one that many people are curious about it. Read on for my two cents on whether or not bleeders are readers, and note that I haven’t updated this because my experience with bleeders remains the same…

I placed the new Dexcom G6 sensor on my abdomen, hovering my index finger above the large orange insertion button. I pressed it, exhaling as I felt the minute needle pierce my skin’s surface. I looked down, and started to rub the adhesive in circles to make sure it was stuck, when I saw blood. Not just a drop, but a decent-sized pool forming beneath the sensor. Before long, just about the entire surface of the white adhesive was soaked in red.

Yeah, this was going to be a no-go.

It’s pretty rare for me to experience blood at the site of a Dexcom sensor. If I had to put a number on it, I would say less than 10% of my insertions draw blood. An even smaller amount – like, 2% – have caused me to bleed as much I did in the scenario described above. But I know I’m not alone in my bloody sensor experiences – it’s something that many other T1Ds who use a Dexcom have gone through.

There’s a bit of debate, though, that I’ve noticed in the past on Twitter threads and Instagram posts. What to do with a bleeder? Keep it and assume that it’ll read blood sugars normally? Or change it immediately and call Dexcom for a replacement?

Are bleeders readers? Or does it depend?

Bloody Dexcom Sensors_ No Go or A-Okay_
Do you think that bleeders are readers?

I’m going to go with…it depends.

Obviously, in that situation I described in the opening of this post, I decided that it wasn’t a good idea to keep the sensor on my body. There was too much blood and I didn’t trust that it would adhere well to my body. I didn’t know how long it would take for the blood to stop (only a few minutes, but still), and I couldn’t be sure that it wouldn’t mess up my readings. On top of that, I wasn’t trying to stain my clothing, if I could help it.

So in that circumstance, I did change my sensor right away, and was glad that the second try resulted in a much cleaner, blood-free insertion. I called Dexcom, explained what happened to the customer support representative, and got a replacement sensor mailed to me.

However, just about any other time I bleed upon a sensor insertion, it tends to be a minuscule amount of blood. I usually don’t even notice until it’s time to replace the sensor, and there’s a bit of dried blood left on the site. Other times, I’ll see small beads of blood forming underneath the spot where the transmitter snaps in. And there’s been a couple of occasions that I’ve bled a fair amount and been totally unaware of it until I caught my reflection in the mirror and noticed the blood staining the white adhesive. And in all of those cases, I’ve kept the sensor on for the full ten days, without noticing any discrepancies in my readings.

All that considered, in my inexpert opinion, I think that bleeders usually are readers and that they’re safe to continue wearing. Of course, there will be exceptions, like when there’s just too much blood to salvage the sensor. But every time I’ve kept using a bloody sensor, I’ve had the same amount of success with its functionality…so yes, I think that for me, bleeders are indeed readers.

TTFN, Twitter

The title of this post really should be “Sorry Twitter but I haven’t been an active user in about two and half months for some specific reasons I’m about to highlight here, but hopefully I’ll come back to you later when things settle down,” but that’s just not very catchy, is it?

Anyways…

The reason why I’m saying ta-ta for now, Twitter, is that it’s become a really tough space to dwell in – or even pop in for a quick visit – throughout this pandemic.

It’s nothing that any account that I follow did or tweeted specifically…it’s just an amalgamation of everything that appears on the site these days. Between the news alerts and downright depressing tweets showing up left and right on my feed, it’s taken a huge hit on my mental health.

TTFN
I’ll return to Twitter full-time…eventually.

It’s a shame because for a long while, Twitter was kind of my go-to in terms of connecting with the diabetes community. I participated in weekly diabetes social media advocacy chats that were a lot of fun and a great way to communicate with fellow T1Ds near and far. But as Twitter grew more and more negative for me, I found myself gravitating more towards Instagram, where things are admittedly a little too shiny/happy/beautiful/perfect all the time. Instagram doesn’t quite fill the void that Twitter did for me in terms of linking up with my T1D community, but it’s something steady I can rely on for now, and with the added benefit of introducing me to other T1Ds who might not be on Twitter.

I’ll end this post by saying that I doubt I’m the only one who feels this way about one or more types of social media during the pandemic. Actually, I know FOR SURE that I’m not the only one who has felt emotionally drained by logging into different platforms and seeing just the one post that is enough to sap you of all positive, happy feelings. And you know what my advice would be to anyone who has felt the same way as me? Recognize it by avoiding those platforms for as long as you need to. I deactivated my Facebook profile for a couple of different weeks so far this year and my mental health absolutely benefited from me doing so. I don’t tap on the Twitter app on my phone lately and I know I’m saving myself from a ton of anxiety and emotional turmoil.

Just like the world has adapted to this “new normal”, it’s all about being pliable enough to see what does and doesn’t work for your mental heath right now, and then identifying alternative ways you can support it.

5 Questions (and Answers) About the Dexcom G6

This post was originally published on Hugging the Cactus on November 19, 2018. I decided to update it, since some of my thoughts and observations on the Dexcom G6 have changed over time due to more experience with it. Updated answers will be in parentheses and/or italics just below (and in some cases, next to) the original answers…

I’ve been lucky enough to have the Dexcom G6 CGM in my life for just over six months now. (It’s actually been about 2 years at this point!) In that time, many people in my life – both T1Ds and non-T1Ds – have asked me countless questions about my experience with the device. I thought it’d make sense to address some of the most commonly asked questions here, in the hopes that I can provide some insight to those who are curious about the Dexcom G6.

Question: Can the Dexcom G6 be restarted?

Answer: In my experience, no. I cannot get the G6 to restart like I could get my G5 to restart. But take my “no” with a grain of salt, here, because I know of other people who HAVE had success restarting their G6 sensor, making its life extend much longer than the 10 days guaranteed by Dexcom. I have only tried to restart the G6 once, with absolutely zero success, following the process outlined here. My advice to those who want to try to restart their G6 is to do so cautiously, and make sure you’re not trying to do so with the last sensor in your stockpile.

Since I initially wrote this, I WAS able to restart the G6 and did so “successfully” a handful of times. But in my opinion, it wasn’t worth it because 1) the sensor would stop reading blood sugars 2-3 days after restarting and 2) I can’t be sure that restarting doesn’t wear out my transmitter faster, which wouldn’t work to my benefit since I don’t know how to reactivate transmitters. My two cents is that while reactivating old Dexcom models like the G4 or G5 often worked well, the technology within the G6 simply isn’t meant for accurate restarting.

Question: Is it actually safe to take acetaminophen (Tylenol) on the Dexcom G6?

Answer: Yes! I’ve noticed that acetaminophen can be taken safely on the G6. I did not anticipate for it to be unsafe, seeing as it was advertised as one of the big improvements Dexcom made from the G5 to the G6. I’ve taken Tylenol a handful of times without noticing any issues with my CGM readings, but as always, be sure to monitor your blood sugar carefully and perform a manual finger stick check if your symptoms don’t match up with your CGM.

This is still absolutely true! I’ve yet to observe Tylenol, or any other drug really, having an impact on my CGM’s readings.

Question: I can’t get my Dexcom G6 sensor to stay put for the full ten days. How do you make it last?

Answer: There’s tons of ways you can help ensure your G6 sensor stays stuck on for the entire ten-day duration. I always make sure that my skin is completely dry before the sensor makes any contact with the site. Avoiding any excess moisture is key in helping it stay put. If I notice the sensor starting to peel around the edges after a few days of wear, then I use a Pump Peelz CGM adhesive to keep it in place. Those tend to work really well for me. In times of serious adhesive doubt, I also use Skin Tac wipes, which basically glue that sucker down. One last tip I recommend is to avoid sites that come into contact with a wide variety of surfaces. In other words, a sensor that’s placed on the abdomen may fare better than a sensor on the leg, because the odds of the sensor getting accidentally knocked off due to contact with clothing or other objects are lesser. You know your own body better than anyone, though, so trust your own judgment when it comes to CGM placement.

So at the time of publication, I hadn’t tried my leg as a site for the CGM. Now that I have, my answer changes a little regarding the “usability” of this site: I’ve had great success keeping the CGM sensor on my leg for the full 10 days without a single peel in the adhesive. Another tip I’ve picked up along the way is to contact Dexcom and ask for their free “overlay patches”, which they produce and that work just like any medical adhesive that Pump Peelz or GrifGrips manufacture especially for Dexcom products.

I just want you to know...
Oh hey, it’s me! In my purple cast showing off the G6. Fun fact: I don’t own an Apple watch – the one I’m wearing here was provided to me to wear just for the G6 promotional materials.

 

Question: Is sensor insertion truly painless?

Answer: For me, G6 insertion has been pain-free approximately 85% of the time. It’s stung slightly a handful of times, but I’ve found that it only hurts when I choose a site that’s not particularly fatty. That’s why I generally stick with my abdomen – either side of my navel – or the back of my arms for G6 insertion.

I stand by this estimate – once in a while, I get a site that’s a little more sensitive and there’s a slight sting, but nothing like it used to be for the G4 or G5. And now that I’ve added my thighs as sites into the mix, I’ve got more site rotation going on, which can help.

Question: Is the G6 really that much more accurate compared to the G5, or any other CGM on the market?

Answer: Yes and no. That may not be a very satisfactory answer, but I’ll explain why that’s my belief. Overall, the G6 seems to be more accurate for me than the previous Dexcom CGM models I’ve worn. Are the number always on point compared to what appears on my meter? No. Do I wear the Dexcom CGM to have an accurate picture of what my exact number is at a given moment in time? Kind of, but I also know that this isn’t totally realistic. After all, users of the Dexcom CGMs know that it measures blood sugar levels in five-minute intervals. It can’t give me a clearer picture of what my blood sugar changes are minute-to-minute. So with that in mind, I find that the G6 is really excellent for monitoring trends – seeing how rapidly my blood sugar is falling or rising, or seeing how it changes gradually over time. The patterns are more important to me than the precise numbers; at least, that’s how I feel in my current stage of diabetes management.

I can’t really speak to other CGMs on the market, such as the Freestyle Libre or Medtronic’s CGM. But what I can say is that I’ve heard less-than-stellar reviews about both. It’s important to remember, though, that they’re not meant to be the exact same as the Dexcom CGM. The Libre itself isn’t really continuous and can’t provide users with information until they chose to wave the receiver over the sensor. And as far as I’m aware, the Medtronic CGM communicates directly with Medtronic pumps, and I’m not sure how seamlessly the systems work together.

Bear in mind that when it all comes down to it, I’m answering these questions with my experience, and my experience alone, in mind. Dexcom is and will always be the number one resource to go to with any questions regarding their CGM devices. But hopefully, the information I’ve shared here will at least help someone who is curious about the G6 feel more motivated to seek additional information. I stand by the fact that it has revolutionized my own diabetes care and management, and though it’s far from being flawless, it’s still an invaluable tool to have incorporated into my daily routine.

I still have not tried any CGM model out on the market except for Dexcom CGMs. To this day, it’s what I know and what I’m most comfortable with, so I don’t anticipate that changing any time soon (though it’d be kind of cool to try another and compare it to my G6). The one thing that has changed is that I rely on my G6 readings a lot more heavily these days. I use a blood sugar meter to check my blood sugar only once or twice a day now, whereas a year and a half ago, I was using it at least four times a day. I’ve put greater trust into my G6, but I do remain cautious against the technology and always check with my meter when I’m not fully believing my G6’s readings.

One Night with Diabetes

You settle into bed, ready to fall asleep after another long day.

But first, you check your blood sugar, just like you do multiple times every day.

Your glucometer reads 201.

Suddenly,  you’re a little nervous to drift off to dreamland, because you just changed your insulin pod an hour earlier and you’re not quite sure if it’s the reason behind the high blood sugar.

You wonder: Could my blood sugar be high due to a miscalculation with insulin or carbs at dinner? Is it because of my stress levels? Is it because I’m dehydrated, or because I’m starting to get sick, or because my new pod’s site is on scar tissue, or because…?

Before long, you feel incredibly exhausted because you’re cycling through what seems like an endless list of reasons why you might have an elevated blood sugar and it has zapped you mentally.

You feel your eyelids grow heavy, and just before you go to sleep, you give yourself an insulin dose that should bring your blood sugar back down before long.

You experience a broken night of sleep.

One Night with Diabetes
When you read this, put yourself in the shoes of a person with diabetes…and this is just one night with the damn thing.

Since your Dexcom app is programmed to alert you when you’re over your high threshold for an extended period of time, it goes off, practically every hour, from 10 P.M. to 1 A.M.

Every time it happens, you wake up to the sound of your Dexcom alarm blaring in your ear.

You worry about waking up others in the household before you even begin to worry about your blood sugar.

You’re pretty sure it’s not a pod problem, since your blood sugar would probably be higher if that were the culprit, but you’re too damn tired to care about the cause at this time of night.

You bolus, go back to sleep, hear a high alarm, wake up, and repeat until finally your sleep stops getting interrupted by your Dexcom.

You get a few hours of broken rest.

You wake up at 6 A.M. and realize that, after all that, your blood sugar levels are still slightly elevated.

You’re pissed that your Dexcom was off by 40+ points, as confirmed by a fingerstick check.

You take more insulin, and force yourself to get up and out of bed because it’s time to start the day: Your diabetes is waiting for nothing, least of all you.

Just another night of not enough sleep and too much worry, thanks to diabetes.

Memory Monday: BD Glucose Tablets

One Monday per month, I’ll take a trip down memory lane and reflect on how much diabetes technology, education, and stigma has changed over the years. Remember when…

…BD glucose tablets were like, the only kind of tabs available?

I remember them vividly. The tablets were came in what looked like giant packages of gum. They were orange-flavored, but colored white. And they were square, chalky, and the epitome of boring. Even so, I’m slightly embarrassed to admit that I used to sneak them from my mom’s purse when I was little. (Sorry, mom.)

I don’t really know why I did it, considering they weren’t exactly the tastiest treats. But it felt rebelliously good to take one here and there, even if I wasn’t experiencing a low blood sugar. I knew I wasn’t allowed to graze on snacks as I wanted, and I knew that it would make my blood sugar go up. I also knew that I didn’t fully understand what diabetes was and why it was so important to be careful with how many glucose tablets I ate at the tender ages of six and seven years old.

Over time, I kicked the habit. As more flavors and varieties of glucose tablets popped up in the market, I grew increasingly resentful of having to use them to treat lows in the first place. I wasn’t enticed by the tropical or berry flavor mixes; after all, they didn’t have quite the same appeal as those weird white tablets.

Today’s glucose tablets come in much more colorful and flavorful varieties.

Now, I’m just glad I’ve discovered ways to bring up a low quickly that don’t involve chewing chalky discs. Orange juice, mini boxes of raisins, gummies, smarties, and more all work efficiently. I still choose to carry around glucose tablets, though, because the tube they come in is discreet. Glucolift brand tablets are a personal favorite to stock the tube with, because they’re more pleasant to ingest, thanks to their quick-dissolve formula. Plus, I can’t totally hate something that’s saved my butt more times than I can count.
