Something that all people with diabetes that I know – myself included – struggle with from time to time is the adhesive that keeps our diabetes devices stuck to our bodies.
Real talk? Both the adhesives for my pods and my Dexcom sensors can be lackluster. About half the time, the adhesives that secure them to my body begin to peel around the edges when I’m only partway through the wear time of both devices. And another (much smaller, though far more infuriating) part of the time, the adhesives lose their stickiness entirely, causing the device to fall off my body.
When the adhesive is the reason why a sensor or a pod doesn’t last the full 10 and 7 days, respectively, it’s practically like experiencing a slap in the face because at least a technology error or failure feels more out of my control…the adhesive, though, feels like something that should never be a real issue, and I can’t help but blame myself for not making a pod or sensor more secure when the glue completely fades.
On the bright side, my experience with less-than-sticky pods and sensors forced me to think of ways to get them to last their full lifecycles on my body. Here’s how I make them last as long as possible:
Protective barrier wipes: I use these wipes each time I do a pod change. When my new pod is priming, I wipe whichever site I’m about to place it on with a protective barrier wipe. (I use an alcohol wipe earlier on in my pod change process.) These seem to help with adhesion without adding a ton of stickiness like regular SkinTac wipes tend to do. They literally do what they say they’ll do, which is make a protective barrier for a piece of medical equipment to stick to easily.
Dry my skin: This seems incredibly obvious, but I make sure that new pod and sensor sites are as dry as possible before I apply a device. This is much more of a problem for me in the summertime when weather causes me to sweat more, but I’ve been able to navigate that by wiping my skin with a clean towel and making sure air is circulating well in the room in which I’m applying the pod or sensor so any excess moisture evaporates off my skin.
Specially designed stickers: Both Dexcom and OmniPod produce stickers that customers can request for free. I get them mailed straight to me and I find that they are most useful when a pod or a sensor is hanging precariously off my body. The stickers are shaped exactly to fit around both, so I never have to worry about missing a spot, and they’ve definitely helped me save more than one pod and sensor in the past. I don’t like wearing them unless I have to, though, because sometimes the extra adhesive seems to make the underlying adhesive weaker (not sure how that’s possible, but I’ve always had more luck waiting to add a sticker on top of a loose pod/sensor that’s in its last couple days of wear than adding the sticker on top in the beginning).
The “circle and press” technique: Most people probably already do this, but I actively have to remind myself that when I apply a new pod or sensor, I need to take my finger and circle it around the adhesive firmly three times in order to make sure it’s pressing up against my skin as securely as possible. This method also sort of irons out any wrinkles that might have appeared when the pod or sensor was initially stuck on, so it’s a simple yet effective thing to do…which is absolutely something we could all use more of when it comes to handling diabetes.
I may have had diabetes for more than three-quarters of my life, but that doesn’t mean that I don’t make silly mistakes with it from time to time.
But I must admit, I still surprise myself on the occasions that I make a slip-up that’s incredibly stupid…and incredibly avoidable.
For example, one morning my Dexcom started alarming, and I thought that I knew exactly why it was sounding off: It sounded like the signature triple buzz of a high alert, so I did what anyone else would do when it’s very early in the morning and not quite time to wake up yet…I ignored it and fell back asleep.
But true to typical Dexcom alarm nature, my sleep was interrupted again by continued buzzing. Rather than pick up my phone to dismiss the alarm, though, I decided to bolus for a couple of units without ever verifying that I was, indeed, high.
Yikes. Can you say rookie mistake?
Fortunately for me, I really did have to get up and start my day within a couple of hours of taking that bolus. Thank goodness I did, because when I got up, I immediately glanced at my Dexcom and was taken aback to see that my blood sugar had not ticked up past my high threshold in the last several hours…it had actually lost reception completely.
Ahh…so that’s what it was trying to tell me. Oops.
Furthermore, my blood sugar was inching below my low threshold – the two units I’d carelessly taken had kicked in, and all I could feel in that moment was relief that I hadn’t taken more insulin.
This story could’ve had a very different ending. I’m still kind of in disbelief that I didn’t just roll over to check my Dexcom and confirm the reason why it was alarming in the first place. I mean, that’s what I do any other time it goes off, regardless of the time of day. I suppose that I was just overly confident in what kind of alarm it was. Coupled with the fact that I was barely awake when this all went down, then it really isn’t all that crazy that this happened…but it doesn’t make me feel any less dumb.
Lesson learned. When it comes to Dexcom alarms, always check them, and never make assumptions.
I’ve decided to take a break from continuous glucose monitoring. This means that for an undefined period of time – maybe 3-4 days, a week, or a few weeks – I’m not going to wear my Dexcom G6 CGM.
Initially, I wanted to give myself a break because I was just burnt out from wearing it all the time and feeling so dependent on it. But as I started thinking about more, I realized that there were some other really great reasons for me to take a break from my CGM:
1 – I wanted to wear one less device. It can be tough to wear two medical devices 24/7. Sometimes I get super self-conscious of them. Other times they just aren’t comfortable to wear, such as when I roll over one the wrong way when I’m sleeping at night. So it’s nice to feel a little more free with one less device stuck to my body at all times.
2 – I was sick of the constant data feed. All those alarms going off whenever I cross my high or low threshold are straight up annoying!!! I know I could just turn them off on my CGM receivers, but the point of them (for me) is to try to maintain as tight of a control on my numbers as possible. But now that I’m intentionally not wearing my CGM, I’m realizing how much I appreciate the reprieve from all that buzzing and beeping.
3 – I have some new blood glucose meters to try. The only way that I can really put my new meters to the *test* (lol) is to use them – and goodness knows that I have very little desire to do manual finger stick checks when I’m wearing my CGM.
4 – I’d like to hold myself more accountable. I rely on my Dexcom heavily at all times. I look to it before I start exercising, before I eat something, before I do anything, really. I bolus using the data it provides and trust it implicitly. But I’ve recognized that by developing this habit, I’ve become lazy. I don’t measure out food as much because I figure that if I bolus too much or too little for it, I can just watch what my Dexcom tells me and treat from there. It’s kinda sloppy, in my humble opinion, so I’m trying to put more of the trust back in myself for my diabetes monitoring.
5 – I’m trying to reacquaint myself with my body’s cues. Before CGM technology, I was really good at recognizing high and low blood sugar symptoms…but then I started using a CGM and found myself reacting to highs and lows (e.g., treating them prematurely), even if I didn’t feel those high/low symptoms. So I want to retrain myself so I can make sure I never lose that ability, because I think it’s important to know exactly how my body alerts me to various blood sugars, rather than depending solely on a piece of technology to do it for me.
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?
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.
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.
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.
So you want to try your first continuous glucose monitor. Or maybe you’re ready to leave behind multiple daily injections and switch to insulin pump therapy. Whichever diabetes device you’re looking to start using, there are some questions you’ll probably want to have answers to before decide that now’s the time to introduce new diabetes technology into your daily routine.
The following is a compilation of the questions that I thought long and hard about (literally for years) and that I wish I’d thought long and hard about before I made the transition to the OmniPod insulin pump.
Am I ready for it? It took me 17 years before I decided that I was ready to try an insulin pump. 17 freakin’ years!!! I spent most of that time being too afraid of introducing such a drastic change to a routine I’d had down pat for such a long period of my life. There are times when I wish I’d gone onto my insulin pump sooner, but ultimately, I’m glad that I wasn’t swayed by my family or doctors to go on it before I truly felt ready. By the time I started using my OmniPod, I had the maturity, responsibility, and emotional intelligence that I felt that I needed for an insulin pump.
Will I be able to afford it? Obviously, this isn’t a question that I wondered about when I was younger, but it’s one of the first things that comes to mind as an adult on her own health care plan. We all know that diabetes supplies are expensive, and it seems that the more technologically advanced something is, the more money that has to be forked over in order to obtain it. This isn’t right or fair, but it’s a simple truth and an important one to think about before choosing one pump or continuous glucose monitor over another.
Why do I want to start using it? I wanted to start using my OmniPod because my mom experienced great success when she started using it. And I decided to get a Dexcom CGM because I fell in love with the technology after undergoing a trial period with my endocrinologist. In both situations, I felt very much in control of my decision to start using these devices and I didn’t really listen to anyone else’s opinions. But I am very aware of the fact that social media and real-life friendships with other people with diabetes can often sway people in different directions. After all, if I saw a post on Instagram from a dia-influencer who was singing the praises of a Tandem T:slim pump, then I might seriously start thinking about switching to it (this has actually happened to me). But the bottom line is to think about the why – will this device enhance quality of life for me? Will diabetes be easier to manage with it? Will it help me achieve my A1c and/or blood sugar goals? Do I need to add something new to my routine because I’m feeling burnt out by doing things the same way all the time? Knowing why I wanted to use an OmniPod or a Dexcom CGM made me feel that much better during the whole process of learning how to use them – I felt like I had clear goals that would help me navigate the integration of these new technologies into my daily routine.
Will I be comfortable wearing it 24/7? This is a big one! Pods, pumps, and CGMs are very visible, and it can be jarring to go from being “naked” to having bumps and lumps underneath clothes that can get caught on doorknobs, chairs, and the like. Personally, the benefits of my OmniPod and Dexcom outweigh something like this which is a bit superficial, but that doesn’t mean it’s not something to think about. But it’s also worth thinking about comfort and what is least painful when it comes to insulin delivery, so that’s why this is an important question to ask.
Do I know anyone else using it who can provide feedback from a patient’s perspective? I’ve talked about this before, but I’m not sure when, if ever, I would have seriously considered using the OmniPod if my mother hadn’t tried it first. The fact that we both have diabetes has probably made us a little closer and strengthened our bond, so if there’s anyone’s opinion that I’m going to trust when it comes to something like this, then it’s hers. I can actually remember her first few weeks on the OmniPod – in which she learned a lot of valuable lessons – and how pleased she was with it once a few months with it elapsed. She taught me the ins and outs of the OmniPod when I started to use it, and I’d argue that her advice was more helpful than that of my diabetes educator. So I’d advocate gathering opinions from family and friends (if either is applicable) or the diabetes online community before going on a new diabetes device, in addition to the research component below…
Have I done enough research on it? …Like any smart shopper, it’s crucial to really consider all options and research them thoroughly, especially when it comes to the top contender. I definitely did not complete sufficient research before going onto the OmniPod or Dexcom; rather, I trusted that they were just right for me. If I were to switch to something else tomorrow, though, you can bet that’d I’d spend a lot of time scouring the web for every last bit of information on the device so I could make the most informed decision possible.
New diabetes technology can be both scary and exciting. But more than anything else, it can really make life with diabetes much more carefree, and I’m glad that in this day and age there are so many options available to people with diabetes that continue to be technologically impressive.
Like many other people with diabetes, I wear two devices on my body at all times: my insulin pump (my pod) and my continuous glucose monitor (CGM). And I’m often asked whether or not these little gadgets are painful.
Fortunately, the answer is that most of the time, they aren’t. I rarely feel it when my CGM sensor or my insulin pod’s cannula pierce my skin, which makes the whole experience of wearing them a lot more comfortable – and much less dreadful when it’s time to rotate sites.
Speaking of sites and pain, though, I admit that there are some sites that, for me, tend to work better than others. The following are the different locations I use for my pod and CGM sensors, in order of what tends to be best to the worst.
Stomach: This is the site at which I have the best insulin absorption, so it’s a clear winner for me when it comes to my pod placement. I also find that it almost never hurts when I press up against the pod (e.g., when I roll over in bed in the middle of the night) when it’s on my belly. The same is true for my CGM sensors, which also seem to be the most accurate when they’re placed on my abdomen. I guess there’s a reason why the stomach site is the only one recommended by the FDA for the Dexcom CGM (which is what I use)!
Lower back: I have yet to try my CGM here, but I often place my pod on my lower back without issue. This site can be trickier to navigate because if I forget that my pod’s there when I’m getting dressed in the morning, I can come precariously close to accidentally knocking it off – and I have in the past. Plus, the pod can rub up against me in an unpleasant way when I’m working out; specifically, doing any sort of abdominal exercise on the ground. But it’s not something I can’t tolerate, and the insulin absorption in this location is just too good in general for me to pass over it altogether.
Upper arm: I wear my pod and CGM on my upper arms sometimes, but they don’t always adhere well for some reason. Getting dressed can be even more problematic for me if I forget that my sites are on my arms – I’ve totally ripped off pods and sensors when I’ve been taking off and putting on clothing. And for a long time, my CGM sensors would make me bleed when I inserted them in my upper arm. I never figured out why, and the problem seems to have gone away, but it definitely made me a little more wary about using my arms as a site (PLUS any devices I wear on my arms are highly visible, and I don’t always like it when people stare at them).
Thigh: Hands-down, the worst site for my pods are my thighs. For starters, wearing denim jeans – especially if they’re skinny jeans – are such a feat when wearing a thigh pod. The fabric pushes up against the pod in such a way that I prefer wearing dresses, skirts, or leggings for the three days that I have a thigh pod just so I can be more comfortable. And speaking of comfort, it’s tough for me to get into a cozy sleeping position when I have a thigh pod because I like sleeping on my stomach sometimes, and there’s just too much pressure up against my pod when it’s on my thigh. And for me, it seems that insulin absorption just isn’t great on my thighs (maybe because they’re on the muscular side). BUT, I will say…I recently tried a CGM sensor on my thigh for the first time and I didn’t hate it! The accuracy was good and it wasn’t in the way as much as a thigh pod (I keep wanting to type “tide pod”) would be. I’ve only had it on my leg for a few days now so I don’t know yet how the adhesive will hold up, but I’ll find out.
Spots I haven’t tried yet (but want to): On social media, I’ve seen people wear Dexcom sensors on their forearms (eek), upper butt cheek (tee-hee), and even on their calves. And pod placement can get even wilder with spots in the center of the back (HOW can people reach back there) and, um, the upper-breast area (one word: ouch). While I don’t think I’ll ever work up the courage to try some of those spots, I am curious about others.
The bottom line is, though, that the sites that work best for me might not work as well for you. (The same thing can be said for my worst sites.) But it is important to remember, above all, the importance of rotating sites…even though I’m clearly not a huge fan of pods on my legs, I’ll still suck it up and place them there because I know that I should be careful of scar tissue buildup.
It just makes the pod-and-sensor-change days that much more pleasant when I can move them from a disliked site to a favorite site, anyways.
Before I dive into this post, I want to make it abundantly clear that I don’t know the answer to this question. I’m not judging how anyone reacted during the recent Dexcom G6 outage, nor am I stating that there was a “right” or a “wrong” way to handle the situation. I merely think it’s important to ask ourselves questions like this when things don’t go according to plan with diabetes care/management.
Alright, now that I’ve got THAT out of the way…
For the last several days, the DOC has been in a bit of a panic. And when I say “bit” I mean “a helluva lot”. That’s because the day after Thanksgiving, Dexcom Follow stopped working. This means that parents/caretakers who rely on the technology to monitor their child’s/loved one’s blood sugar levels were left in the dark. It sparked confusion, outrage, and downright fear, all of which only seemed to intensify over the weekend and into this week when the problem was only partially solved for most users.
Rather than coming together to support one another, the DOC swiftly divided into two camps: The first consisted of individuals who sought to gently remind others that this technology is still pretty new. It hasn’t even been around for two decades. That meant that for many years before then, people with diabetes were doing things the “old school” way, and getting by just fine. Doesn’t this mean that we should all be able to make it through unexpected technology blackouts, knowing that we have our blood sugar meters to fall back on?
The second camp was in a greater fury over the issue. This camp relied on the Dexcom G6 system because those within it simply didn’t know a life without the continuous glucose monitoring technology. For them, the outage was a bit like asking them to Google something without access to the Internet – it’s pretty much impossible, unless you’ve got an Encyclopedia handy. Oh, and it’s MUCH higher stakes, because people who don’t recognize symptoms of low or high blood sugar need this technology to work in order to stay on top of fluctuating blood sugar levels. Let’s not even get into how much is PAID for this expensive piece of medical equipment…one would argue that the high cost of supplies means that the technology should work at all times, no matter what.
If you’re like me, you can see that both of these groups have perfectly valid points. I’ve had diabetes long enough that I didn’t even use – and didn’t see the point in using – continuous glucose monitoring or insulin pumps until a few years ago. I took care of my diabetes the old fashioned way growing up: doing fingerstick checks multiple times per day, treating low blood sugars with 15 carbs then waiting 15 minutes, checking blood sugar levels about an hour after injecting insulin to make sure highs were coming down the way they should. This way of handling diabetes worked for me for a long, long time…throughout elementary, middle, and high school, right up to college.
Then I got a continuous glucose monitor (I believe it was the Dexcom G4) just before starting my freshman year of college. And I haven’t really been without a CGM device since then. It’s changed my life and helped me navigate adulthood with diabetes. Whenever I do experience periods of the technology not working the way it should, it’s infuriating because I feel like it’s not worth throwing away buckets of cash on it in those periods of inconsistency and inaccuracy.
But here’s what I’m wondering, as a result of this Great Dexcom G6 Outage of 2019…do we take this technology for granted?
Do we truly appreciate the times that it works the way it should?
Do we expect too much from something that, technologically speaking, still has a long way to go in terms of working perfectly?
Do we rely too heavily on continuous glucose monitors to provide us peace of mind when, in reality, they simply provide us with real-time updates of our blood sugar levels (i.e., it’s a stream of data)?
I don’t have answers to these questions. I can reflect on my own answers to them; furthermore, I can ponder how and why the DOC gets so divisive in these times where we should try to come together, listen to (and learn from) differing perspectives, and figure out what we can do to best support one another during trying times.
I saw an Instagram story a few weeks back that intrigued me.
In it, a friend of mine was talking about how she “soaks” her CGM sensors. Instantly, I was confused: What the heck did she mean by that? Soaks them in what, hot water or some other liquid?
Within seconds, her definition of “soaking” became much clearer. “Soaking” a CGM sensor means inserting a fresh sensor hours before you intend to activate it. Rather than giving your sensor just two hours to warm-up, you’re giving it 4-6 hours so it can supposedly provide much more accurate readings immediately after the warm-up period has ended.
I was interested in this practice because I’ve definitely experienced sensors that were off for several hours post-insertion/warm-up. Sometimes, it even takes a full day for a sensor to start reporting accurate numbers, and I wouldn’t exactly call that efficient.
While I haven’t had the guts to actually try sensor soaking yet – I’d like to sometime in the near future – I’ve been doing some research on it so I’m fully prepared to try it whenever I’d like. Here are some questions I had about the process, and the answers I’ve found to them:
Q: Doesn’t this mean that you’re wearing two sensors at once? A: Yes. But it’s only for a short window of time, until the old sensor expires and it’s time to activate the new one; in other words, for the full soaking period.
Q: How long should I let a new sensor soak?
A: According to what I’ve found online, it seems that 4 to 6 hours is the sweet spot for soaking. It’s basically doubling or tripling the built-in warm-up period that all sensors must go through, so I can see how this might contribute to improving immediate accuracy.
Q: How do I protect the new sensor if it doesn’t have a transmitter snapped in it for several hours?
A: The reason why I haven’t tried soaking yet is because I was worried about wearing a sensor that didn’t have a transmitter snapped in it. But I found some photos online of people who wore transmitter-less sensors with stretchy, self-adhesive wrap tape to protect the nook in which transmitters rest for the soaking period. It’s smart to protect that space, because in theory, it could be vulnerable to catching on clothing or other surfaces. Plus, tape like that is really easy to remove without damaging the sensor in the process.
Q: What changes about the sensor activation process when it’s finally time to start the new soaked sensor?
A: My research leads me to believe that nothing really changes at the end of the soaking period/when it’s time to activate the soaked sensor. All that will be needed is the sensor code so it can be properly activated within the receiver/Dexcom app. So the most important thing you can do at the very start of the soaking period is hold onto your sensor code/store it somewhere safe so you’ll be able to enter it at the end.
Q: So…why would anyone bother trying this again? A: My understanding is that it all relates back to making sure a fresh sensor is as accurate as possible once it’s activated. I can’t tell you how many times I’ve put on a new sensor, only to discover a few hours after it has warmed up that it’s off by 40 or 50 points – and that just doesn’t cut it. So I don’t think there’s any harm in me giving sensor soaking a shot one of these days. I just have to remember to do it, and have the patience to wear three devices at once (my pod, the soon-to-expire sensor, and the new soaking sensor).
Have you tried soaking? If so, please drop a comment and let me know your thoughts on it – and be sure to tell me if I missed any key steps in my research!
In my unofficial opinion: Yes, Dexcom G6 transmitters lose accuracy as they approach their expiration dates. And I’m not quite sure if I’m the only one who has noticed this, or if others have also experienced this frustrating phenomenon.
I’m writing this after dealing with a dying transmitter that was showing its signs of decay by 1) losing connectivity with my receiver and 2) reporting inaccurate blood sugar readings. I’ve definitely narrowed the problem down to my aging transmitter, which (allegedly) had one session left before it was set to expire – everything else about this particular sensor session was standard procedure. And guess what else, everything about the entire 10-day session was obnoxious, because it was rare for me to have a single day with both accurate and consistent readings. Ugh!!!
I don’t know what’s more irritating – the signal loss or the inaccuracies. Actually, I DO know what irritates me more than anything else, and that’s the fact that the transmitters don’t seem to last for as long as they’re advertised. It’s just ludicrous, especially when you take into account how much these devices cost.
Many people with diabetes rely on this, and other forms of technology, to effectively manage diabetes. And when the technology can’t be relied on to do its job, we can’t perform our jobs as well. Diabetes is draining enough – is it too much to ask for technology to be trustworthy?
