WTF is CGM Sensor Soaking?

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?

HUGGING THE CACTUS - A T1D BLOG
Contrary to the connotation of the word “soaking”, this does not mean you’ll be submerging your CGM in any sort of 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!

Do Dexcom G6 Readings Become Less Accurate as Transmitters Age?

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.

Let us help you find your center www.reallygreatsite.com.png
In my unprofessional opinion, yes!

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?

How I’m Changing My Reaction to High and Low Blood Sugars

I’m doing a total system reboot…of myself.

I want to change how I react to high and low blood sugars.

Why?

Well, I think that it’s about time for me to address my intense fear of low blood sugars, but I also feel that I need to reconsider how I define high blood sugar. I’ve been sick and tired of dealing with constant highs, sprinkled with a few lows, so all of that together has motivated me to come up with a plan.

My plan is two-fold:

Step 1) Change the low and high thresholds on my CGM from 80-180 to 75-160.

Step 2) Pay closer attention to my body’s cues when my blood sugar is low.

how i'm changing my reaction to low and high blood sugars
It won’t be easy to change how I react to low/high blood sugars, but I think it’s necessary.

The first step was extremely easy to follow. I modified the settings on the Dexcom app on my phone so I’m only alerted when my blood sugar goes above 160 and below 75. I’m hearing my Dexcom alarms more often as a result, but I’m also responding to these alarms more frequently, meaning that I spend less time overall above/below my goal blood sugars. It requires a little more work and patience, especially since I experienced a lot of stress and a cold in the weeks since I’ve made the change (stress + sickness = shitty high blood sugars), but I know that it will be worth the effort.

The second step is slightly trickier. I’m the kind of person who starts treating a low blood sugar early – I’m talking as “low” as 90. And that’s not low. Unless I have several units of insulin onboard or I’m about to do a moderate intensity workout, there’s no need for me to eat anything when my blood sugar is 90. But it’s easier said than done, because I actually do start to feel low blood sugar symptoms at 90 (not all the time, but definitely a chunk of it).

So I’m hoping that this is where step one will come in handy. I’ll use my new low threshold on my CGM to reorient my body’s recognition of low blood sugars. I’m also going to work on not panicking when I start to feel low…because I think that’s the real root of my problems. In the last several years, I’ve developed – for no apparent reason – a serious low blood sugar phobia. I do everything I can to avoid them at all costs, and that’s probably contributing to my recurring high blood sugars. And that is definitely not good.

I’m over living my life on a blood sugar roller coaster…so I’m looking forward to smoother sailing with this plan of mine. Updates to come, for sure.

 

 

The Low I Didn’t Feel

Do you ever feel so engrossed in a task that something (like the time) sneaks up on you, and totally disarms you and puts you in panic mode?

That’s sort of what happens when you don’t feel the symptoms of a low blood sugar. Usually, I’m lucky enough to say that I feel my low blood sugar symptoms – shakiness, sweating, dizziness – but unexpectedly, I didn’t feel them during a recent low blood sugar episode. And it nearly knocked me off my feet.

I’d been traveling all day long. I’d taken an Uber from my apartment to the airport, where I waited a couple hours to catch my flight, which was so turbulent that I nearly yakked on the tarmac. When I finally arrived to the airport and lugged my bags up to the hotel room that I was staying at, I was struck by how queasy my stomach still felt and chalked it up to after effects of the turbulence.

I figured my body was just mad at me for skipping dinner. It was already 9 at night and I didn’t really want to go back down to the crowded terminal just to get a mediocre fast-food dinner. That’s when I decided to check my blood sugar: That would determine how necessary food was for me at that point in time.

The low I didn’t feel.

Just as I was taking my kit out of my bag, my CGM alarmed. According to it, I was low – low enough that I’d be below 55 within the next 20 minutes. “Impossible”, I thought. I feel my low symptoms coming on when I’m 80 mg/dL sometimes, so I was convinced there was something wrong with my CGM. I proceeded with the fingerstick check. The result popped up on my screen: 65. What? How? I could’ve chalked it up to a long travel day, but at that moment in time, I didn’t care about the cause. I only cared about the fact that I didn’t feel it whatsoever.

It was scary and an unpleasant surprise. As I sat down on the hotel bed and crammed M&Ms in my mouth, I felt a little confused about how I got so low (especially since I’d been eyeing my slightly-elevated blood sugar all day). But mostly I felt gratitude for my CGM. Times like these make me feel incredibly privileged to have one. I find its alarms annoying and I don’t love wearing an extra thing on my body, but its functionality makes it totally worth it.

Why is it so Difficult to Order Life-Saving Medical Supplies?

When it comes to obtaining my diabetes supplies – life-saving pieces of medical equipment – I’ve discovered that it’s not a simple process. It’s not exactly like purchasing something on Amazon with a single click. Rather, it’s a convoluted, head-scratching, infuriatingly long procedure that apparently involves multiple calls to a variety of companies.

As of this writing, it took approximately 4 calls to my endocrinologist’s office, 12-14 calls to Insulet (the maker of my OmniPod insulin pump), 6 or 7 calls to Dexcom (for my CGM supplies), 2 calls to my health insurance provider, and 1 call to Express Scripts just to get everything all straightened away. These calls took place over the course of 2.5 months, and as they grew in frequency, so did my overall frustration and confusion.

The biggest headache was definitely caused by the lack of effective communication between Insulet and my endocrinologist’s office. I needed to get a new PDM, and Insulet’s job was to contact my doctor’s office and get a letter of medical necessity in order to get a PDM shipped out to me. Simple, right?

Why is it so Difficult to Order Life-Saving Medical Supplies_
My call log looked like this for several days in July – so many phone calls to Insulet/OmniPod and to my doctor.

Far from it. About a week after I placed the order for the new PDM, I got an email from Insulet saying that my doctor’s office had failed to return their faxes. I was advised to contact them to determine the delay. When I did, I spoke with a receptionist who, despite my clear explanation of the issue, misunderstood what I was asking for and left me a voicemail to say that she didn’t know what Insulet was talking about seeing as their information showed that I had received a shipment from them. (For whatever reason, she thought I needed more pods, which I did have delivered around the same time that all of this was going on.)

After several more back-and-forth phone calls, I cracked the case wide open: Insulet had the wrong contact information for my doctor. While my endocrinologist hasn’t changed in about a decade, her office location has, and Insulet still had the old one. I felt like an idiot for not realizing this sooner, but then again…why was I the one who was jumping through so many hoops and making so many contact attempts in order to figure out what the hold-up was? It was absolutely ridiculous, but I certainly felt relieved – and satisfied – to have personally solved the mystery.

I wish I could say I had a better experience with Dexcom, but that proved to be similarly headache-inducing. I thought that I was set to receive my supplies after I’d signed a payment plan for a 90-day supply of sensors and transmitters, but when they didn’t show up after a month of waiting, I knew something was wrong. I called Dexcom and discovered that the order, for reasons unknown, just didn’t process, so I had to sign a brand-new payment plan and had my case assigned to a different customer service rep. I was pretty pissed off by the lack of communication, but the one silver lining was that I’d already managed to pay my deductible in full (ha, no surprises there), so my Dexcom supply order would cost me less. Again, it was unbelievable that I never got an update from the company regarding my order’s status, but I did feel a sting of pride in myself for getting it all worked out on my own.

I don’t know why everything about this process is so agonizing. But what I do know for sure is that it seems that the only person I can count on to get my supplies ordered properly, in the end, is myself.

Doing Everything Right and Still Getting it Wrong

One of the most frustrating things about having diabetes is feeling like you’re finally understanding it, perhaps even mastering it, only for it to lash out at you and make you feel like you don’t know shit about it.

It’s when you do everything right – check and treat accordingly, eat properly, exercise sufficiently – and still get it wrong when your blood sugars don’t behave the way they should.

I really hate when this happens, but I loathe when it happens on vacation…which is exactly what happened to me last week when I was in Maine for a few days.

Things started going awry shortly after I woke up (if only I knew then that I was in for a DAY!!!). I ate breakfast and my blood sugar swiftly started to rise. But I didn’t panic, because that’s what I wanted to happen. We’d be walking all around town for part of the morning and most of the afternoon, so I wanted my blood sugar to be on the higher side so that my chances of dropping dramatically in the heat were lower. I made the right call – soon after we got downtown, I noticed a diagonal down arrow on my Dexcom app. Things were headed in the right direction…or so I thought.

Not long after I spotted the diagonal arrow, I started to feel a little low-ish. Not super shaky or anything, but just a bit disoriented. I decided to pop into my favorite candy store to fill a small bag with treats so I had something sugary to munch on that would prevent a bad low blood sugar.

Those were mistakes number one and two…not consulting with my CGM again before eating candy, and going to town on it because it was CANDY and it tasted delicious.

Doing Everything Right and Still Getting it Wrong

Within a half hour, I was rising up, up, and up. I took a small amount of insulin to correct it, not wanting to be too aggressive and risk a real low. But as I walked around the amusement park with my boyfriend and his family, I just wasn’t coming back down like I thought I would. I lingered in the mid-200s for much of the early afternoon, and by the time we stopped for lunch, I was rage-bolusing to bring my numbers down faster. I even chose a lower-carb lunch option in the hopes that it’d stave off another high blood sugar, but nope, the BG gods were not in my favor that afternoon. As we moved from the amusement park to a brewery (a drastically different change in locale, I know), I bolused once again, and then noticed that the batteries in my PDM were low.

And that actually wasn’t a problem, because I was prepared enough to have spare triple A batteries on me – thank goodness! I took the old ones out, popped the new ones in, and waited for my PDM to come back to life. And it did…but it asked me to input the month, day, and year.

Dammit. THAT’S never a good sign. I entered the information and the system accepted it, and then my pod failed immediately after, which meant that I had to ditch the brewery and the group of people that I was with to get back to the house we were staying at as quickly as possible to put a new one on.

It doesn’t get much more irritating than that.

(Later, I discovered that my PDM’s internal battery was going, and that this behavior would occur every time I replaced the triple A batteries. Needless to say, I’m awaiting a new PDM from Insulet, because it’s just not smart to continue using an aging PDM.)

By the end of this day of turbulent blood sugars and unpredictable medical device malfunctions, I was mentally beat. I felt like I’d been thrown into the roughest of ocean waters and forced to tread water for hours in order to keep my head above the surface. It’s exhausting to know that, when it’s all said and done, I was really trying to do the right things and take care of myself. I was SO DANG PREPARED with those extra triple A batteries, for goodness’ sake! But man, diabetes…just when I think I know it better than anything else, it throws me for a loop and I remember a saying from Professor Mad-Eye Moody of the Harry Potter series (of course I’m talking about Harry Potter again, don’t act surprised): CONSTANT VIGILANCE. I’ve got to be aware of my diabetes at all times. I’ve got to know how to react and when so that my diabetes will remain in my charge – not the other way around.

Supporting T1D Students with my #SensorSelfie
