how to write a diabetic character: CGM edition

is your diabetic character wearing a CGM? do they have to? CGMs these are Continous Glucose Monitors that can detect how much sugar is in your bloodstream.

How are they different than tradtional fingerprick (blood) tests? they take blood sugar readings 24/7, and provide you with how your sugars are doing at all times, rather than just at that moment. This leads to tremendously better control over blood sugar.

The way they work is that they can "sample" your blood sugar by testing your subcutaneous tissue for sugar levels then adjusting that value.

However, they're less accurate than a fingerprick (blood) reading and will often "lag" behind by about 15 minutes.

SO if you have a character who is expereincing low or high blood sugar - they'd get an alarm on their CGM, and then they might take a fingerprick reading to make sure. CGM false alarms DO exist and it can cause some very annoying situations.

A less careful/depressed/struggling/burnt out character might A. not care or "sleep through" alarms B. not double check with a finger prick C. not care that they're wearing a CGM - pump into stuff or just rip it off (although they are very expensive!).

can you mute them? yes, and a character might choose to do this while they're sleeping, having an exam, or if they know they're about to fuck up their blood sugar.

how long do they last? the libre ones last 14 days. the dexcom ones last up to 10 days.

can you shower with them? yes

can you swim with them? yes

can you have sex with them on? yes, and i've read very funny anecdotes from diabetics having to pause during sex because their cgm was beeping

are they expensive? yes! sometimes, they're covered by insurance, but not completely. If a character is in poverty, or do not have insurance, they likely would have to rely solely on fingerpricks.

Who usually uses CGMs? they are very widespread between T1Ds and are increasingly being used by T2Ds as well.

can you share the readings on multiple devices? yes! your character might share their info with their SO, parents, roommates, close friends...etc. It is genuienly one of the most telling signs of a close relationship between people - because those people will see your "mistakes" and decisions.

where do you stick them? the libre ones (circular ones) officially just go on the back of your arm. The dexcom ones can go on just about anywhere that's "soft" - stomach, thighs, back of arm, chest...etc.

does putting them on hurt? sometimes! the way they are installed involves a needle going into the skin then sitting in the subcutaneous tissue. This can sometimes cause some bleeding, and soreness for a few hours.

Often times the process is completely painless, but this is not the case for everyone. A thinner character might struggle to find a place "cushy" enough for a cgm.

can you put them on your own? yes the process is made for one person to stick it on, but i've seen some couples on instagram act all romantic and sappy about applying it together, so that should give you some ideas for your diabetic characters' budding romances ;)

Some CGMs are just naturally faulty, i'd say about 4 sensors is a busted one, and in that case you'll have to replace them - which most companies just do without any hassle.

do they work with insulin pumps? some insulin pumps can work in tangent with CGMs and provide feedback for the user to automatically generate the correct doses of insulin, depending on their current blood sugar.

do they come off easily? depends on who you're asking. some people swear up and down that they never last and have to put on patches, which are admittedly very cute. Weather, clothing, and how clumsy a character is all factor in this. For me personally i just put them on raw and keep them together by sheer willpower.

CGMs can cause anxiety in diabetics. The constant flow of information can easily burnout people, and this can possibly be the case for any diabetic character you might write. Seeing arrows going down or up can be very distressing, especially knowing how painful some of the consequences are. I personally take breaks for both myself and my wallet from using CGMs to avoid burn out.

nonetheless, CGMs are WONDERFUL pieces of technology that have personally made me much happier as a diabetic, freer and a lot more independent.

does your character want their CGM to show? lots of people, including myself don't like revealing their CGMs - but your character might like showing them off!

and lastly - my favorite thing about CGMs - taking them off and having a "naked" shower once a month where i dont have to worry about it coming off. - They look like this:

I was doing really great the past 2 weeks, and I was extra excited, but I messed up yesterday & today. It may not be that much of a mess compared to many others, but still.. extremely disappointed in myself.

[ticslikedabee]

So I have a freestyle Libre 2 right? And they’re doing updates that gives us continuous monitoring now.

However I just updated and now my sensor won’t scan.

I’m going to an event tomorrow

I need to use my sensor. I don’t want to lug around my entire kit.

I am frustrated but I understand Abbott is doing their best considering all the bugs they have with this new update

[glucose-gay]

me checking my blood sugar: there better not be any fucken 🅱️ees in there 🤨

[goldenhornss]

I CAN CHECK MY SUGAR THROUGH A THICC SWEATER WHAT

[needlepokes]

does anyone know if i can use apple watch with freestyle libre 1 ???

(no they still havent made FL2 sensors available here 🫠)

[t1ddiscoveries]

I have the libre 3 plus and sadly I won’t skip warm up no matter how long it is left in for. It’s cool that the g7 does that though!

Hey t1diabetes tumblr (if you exist) I found out that if you have a dexcom g7 and you put it on like 30 minutes before you actually start it from the app it skips the warm up thing immediately and goes straight to reading your bg so !! :] not sure if it works with other cgms like the libre but it probably should seeing as it’s the same basic principle

When your horse (Fjara) decides to grab that fun little wire poking out from your pocket and won’t let go despite you begging her to and then manages to damage the infusion tube juuust enough to break down the whole system 🤣

I went to a Christmas party the other day and decided to add diamantés to my arm sensor. I think this may be the most inspired thing I’ve ever done.

"Se que fui malo y ahora lo se...

Te perdi por tonto y por tonto no estoy bien"

[majestymonarch]

Why? You might ask. My continuous glucose monitor needs to be physically plunged into my arm and it has a visible centimeter long needle.

Turns out your brain isn’t a huge fan of purposefully stabbing yourself, so I’ve always needed help.

Not today though, shit worked.

Just mentally did the lungs, heart, liver, nerves chant from slay the princess for like 5 minutes.

[homosexualtoothbrush]

I fucking hate my glucose sensor. It wouldnt shut the fuck up for a while and then it fucking fell out. Now i gotta wait for my partner to come home bc i dont know how to put one in myself

[diabeticcorner]

Are you in search of Free Style Libre Flash Glucose Monitoring System? You have come to the right place. FreeStyleLibre 2, 14 day Flash Glucose Monitoring systems are continuous glucose monitoring devices indicated for replacing blood glucose testing and detecting trends and tracking patterns aiding in the detection of episodes of hyperglycemia and hypoglycemia.

my day has also consisted of a panicked email to one of my endocrinologists going 'yeah my numbers are in the good range but THEY DONT USUALLY STAY IN THIS PART OF IT IS THAT OKAY.' so ive got a lot happening in the brain

[detective-like-i-give-a-damn]

I never know what my cat's blood sugar is because the freestyle libre 3 only goes up to 350
