What to Work On.

I’ve gotten lazy in my diabetes management.  And I’m not proud of it.  My recent A1C result was still in my goal range but not where it was a few months ago, and I’d love to return to that level of control.  Thing is, I’ve gone soft when it comes to following through on my daily diabetes duties.

Yeah.  I’m at that point in the postpartum recovery thing:  finding ways to up my diabetes game.

I can check two things off my to do list with confidence:  I wear  my Dexcom every, single day and I also have been on top of my doctor’s appointments.  Those two things get big, fat gold stars.

Other stuff needs some grooming, though.  Here’s my wishlist:

  • Check fasting BG immediately after waking up.
  • Calibrate CGM right when it requests calibration.
  • Pre-bolus at least 15 minutes before eating.
  • Exercise 3 – 5 times a week.
  • Sleep more than 5 hours a night.
  • React faster to the high alarm from my Dexcom.
  • Rotate my device sites better.
  • Remember to eat more than coffee before 1 pm.

Hmmm.  That’s a lot.  Plan of attack for each:

  • Check fasting BG immediately after waking up.  We just moved the little Guy out of our bedroom and now he’s sleeping in his crib in his own room, so I have a little more time (3 min versus zero min) in the morning before I have to run and grab him.  I need to return to the habit of keeping my glucose meter on the bathroom counter and using it before I brush my teeth in the morning.
  • Calibrate CGM right when it requests calibration.  Ugh.  This just requires being less of a lazy tool and just checking/calibrating ASAP instead of ignoring the little red blood drop.
  • Pre-bolus at least 15 minutes before eating. This one is admittedly going to be challenging, as my schedule is a little non-scheduley these days.  My son is a busy little creature and also unpredictable, so it’s challenging to find the “right time” to do things like change out my insulin pump, eat breakfast, schedule conference calls.  But as he gets older, he does seem to be settling into something resembling a pattern, so maybe this will get easier.  I’ll try to pre-bolus.
  • Exercise 3 – 5 times a week.  This one is already going in the right direction.  As mentioned, I joined a gym and that gym has childcare, so there’s no excuse.  Except days like over the weekend, when I was away for work, or today, when the little Guy is so sniffling and booger-gross that I don’t want to bring him to the daycare and expose any other kids/adults to his germs.  We did go for a walk around the neighborhood today, clocking in at least a little bit of exercise, so that helps.  The weather warming up will help here, too.  This bullet point is one I’m putting like half a gold star on.
  • Sleep more than 6 hours a night.  OH HA HA HA HA.  The baby thinks 5.30 am is when human beings should wake up.  The early morning hours are gorgeous and I love the quiet of being awake that early, but around 10 pm my body starts to give up on doing body things, although I rarely make it to bed before 11.30 pm.  I need to work on this sleep thing.
  • React faster to the high alarm from my Dexcom.  Again, this one is something I just have to DO.  No excuses and no reason not to.  My high alarm used to be 140 mg/dL (pre-pregnancy and during pregnancy), but I’ve moved it to 180 mg/dL in the last few months.  I should be responding to 180s.  I will work on this.
  • Rotate my device sites better.  Yep, this is also a need.  My thighs have become a permanent home for my Dexcom sensors, but I am okay with the back of my hip or maybe my arm.  I’ll try to get creative.  As far as pump sites, I’ve been working on rotating those better, too.  Maybe it’s time to try a lower arm site?  (Has anyone ever done that and does it hurt??)
  • Remember to eat more than coffee before 1 pm.  Yeah, this is another whoops.  My mornings are generally a bit crazy, and sometimes I’d rather keep my CGM graph steady instead of interrupting it with breakfast.  But this is backfiring because I then get so hungry around lunch time that I eat the fridge, causing a nasty post-lunch bounce.  Moderation here.  Eat regularly throughout the day and I’ll be less likely to unhinge my jaws and devour the contents of the cupboard.

I hope writing this crap down will help up my accountability and will inspire me to keep moving forward.  If I can make one or two of these become habit in the next few weeks, I’ll mark that as a success.  Because backwards is all gross and disgusting feeling and also it looks like there’s a c-section back there and I am NOT going back to that.

The Follow Up About Dexcom.

Today is Day 7.  I’ll be pulling this sensor off in six hours.

Day 7. No filter. No rash. No worries. #dexcom

A post shared by Kerri Sparling (@sixuntilme) on

No rash.  No filter.  Does this mean no worries?

(For reference, this post is a follow up from a week ago when I put on a Dexcom G5 sensor and transmitter without a barrier underneath the sensor.  For the last four and a half years, I’ve had an allergic/irritation response to the sensor.  Big, scaly rashes would blister up and take weeks to heal … like the one currently on my left thigh.  But rumor had it that sensors with an expiration date past 8/17/2017 were not causing this rash reaction.  

So I tried a 11/2017 expiration-dated sensor and the result?  No rash. NO RASH! The only issue I noticed was some blood around the transmitter after inserting it, but I wonder if that happens more often than I realize and the Toughpad had previously kept the blood from being visible. Whatever the case, I’m not itchy yet and I’m really, really hopeful that this rash issue is tabled forever. Next question is what to do with the box of sensors that has a pre-August 2017 expiration date …)

Dexcom Rash: Updated.

Frigging rash.  The issue first presented itself back in August 2012, leaving me scratching my head and itching my sensor sites for the next four years.

At first, I tackled the problem by trying a pile of different barrier tapes, but the only one that brought about any semblance of relief was the Toughpad.  For about a year, I used a Flovent inhaler (sprayed on my skin before applying the CGM sensor), but I was cautioned against it by my first dermatologist, who cited that the skin would become thinner and compromised after prolonged use.  For the last few years, I’ve used the Toughpad exclusively, and it’s held the rash at bay.

Sort of.

It’s never ever perfect.  I’m still itchy as eff sometimes when I’m in the midst of using a sensor (like right now, with my sensor on my right thigh and the skin around the Toughpad is bright red and I want to scratch it off until my nails break but the low alarm that went off two nights ago saved my ass entirely so I’m leaving the sensor on as long as I can stand it).  The rash doesn’t seem to be concentrated underneath the Toughpad as much as before, but now I appear to be allergic to the Opsite Flexifix tape.  Add that to the fact that I get skin irritation even if I put the new sensor next to any place where a sensor has even BEEN for the last month.

A week or two ago, I went to the dermatologist to further investigate my Dexcom rash and to hopefully find different ways to scratch that itch, so to speak.

The new dermatologist circled me like a shark, only maybe a shark in search of medical journal material.  “You’re having an allergic response to the medical device adhesive?”

“Yes.  Since 2012.”

He paused.  “So just don’t use that medical device?”

“Not an option.”  (Totally not an option, especially these days, when I can’t feel my low blood sugar symptoms and I don’t take action on my high blood sugar symptoms unless the CGM is alarming.  This is why I wear a CGM.  And while I’m taking care of two little kids, this is why I will continue to wear my CGM.)

“Okay …” said the dermatologist, looking at my arm and thighs again, assessing the skin damage.  “A Flovent inhaler, too?  You mentioned using that in the past?”

“Yes, but after being warned it would thin out my skin, I stopped.”

“Good call.  Listen, I think we can try two things:  a topical steroid cream, or a non-steroid topical cream.  I would like try the non-steroid one first, because the same skin-thinning issue would happen otherwise.”  He handed me a prescription.

We scheduled a follow up appointment and I was sent on my scratchy way.  The cream, it turns out, comes with a dozen different creepy warnings that have made me very reluctant to try it while breastfeeding my son, but I did put a little bit on my rash and, within the hour, my rash was on fire and the urge to itch was all consuming.  I’m not touching this stuff again until after I’m done breastfeeding, and even then I’ll be very conservative, in case I’m allergic to this shit, too.

I’m not sure what people are doing these days to manage their adhesive irritations, but I’m reaching the end of my available skin real estate.  Any advice out there? It’s been a very long few years of wearing the CGM 24/7 and I’ve just about run out of sites that aren’t already scaly and raw.  I hear rumors about a “sensitive” adhesive being released by the Dexcom team, and about certain elements being removed from the current adhesive makeup, but until those products are shipped to my house and not sending my skin into circus mode, I’m at an itchy loss.

Enjoy the Silence. Or Not So Much.

[Disclosure about my relationship with Dexcom]

During the first trimester of this pregnancy, lows were intense and weirdly symptomatic; a nice contrast from the hypoglycemia unawareness that’s crept in over the last five or six years.  (I ended up stashing a jar of jellybeans in the dining room hutch, only to have to move it into direct line of sight in the kitchen in efforts to keep up with the persistent low blood sugars of those first few weeks.)  As this pregnancy has moved forward, the lows have become slightly more predictable and the hypo-unawareness has returned, making the Dexcom BEEPS! and BLARGHS! more necessary.

Until that week when I noticed, “Hey, the alarms have been quieter.”  And then I realized, “Hey, the alarms aren’t working.”  Because overnight, my G4 receiver had been rendered mute.

When I received the Dexcom recall notice several months ago, it was very early February, and I was still using the G5 transmitter.  At the time, the only people who knew I was pregnant were my family and my medical team, but I knew, and I was stalking blood sugars with vigor (and a side of panic).  My endocrinologist, not a fan of the data output from the G5 application, asked if I would consider using the G4 for the remainder of my pregnancy.  Wanting her to check the “compliant” box on my chart (there’s a first time for everything), I switched back to the G4 the following week and have been on it since.

And for months, my G4 receiver was fine.  Alarmed all the damn time, vibrating and buzzing from my bedside table or my purse and alerting me to the changing needs of my baby-hosting body.  And then, all of a sudden, the speaker went full garbage, not working at all.  Only a vibration came from the receiver, making my phone* the best laid plan for alerting me audibly.

It wasn’t until I woke up one morning and saw the empty raisin box and the discarded juice box that I realized the night before wasn’t very comfortable.  And that I didn’t wake up because of alarms, but instead because of aggressive baby kicks.  I couldn’t ride out the rest of this pregnancy without replacing the receiver, because I was NOT waking up even with the phone alarms.  I needed high octane, receiver-in-a-glass-with-some-coins sort of jolting.  I needed to connect the alarms to Siah, encouraging her to walk across my face when I was low.  Or similar.

I needed the receiver to actually WORK PROPERLY.

So I went to the website – Dexcom has a special page set up for this particular issue.  There’s also a special hotline number to call: (844) 607-8398.  After a quick exchange with the woman on the phone, she asked me to confirm that my alarms weren’t working by doing the following:

  • press the center button on your receiver to access the Main Menu
  • scroll down to Profiles
  • select Profiles
  • scroll down to Try It
  • select Try It
  • scroll down to 55 Fixed Low
  • select 55 Fixed Low
  • verify that you receive vibrations first (vibratory portion of alarm), followed by beeps (audible portion of alarm).

And once we confirmed the alarm absence, a new receiver was scheduled to be shipped out.  Should be arriving in the next few days, in time for me to finish up this pregnancy as a G4 user (to make my doctor happy) and hopefully by staying in my threshold lines (to make my fetus happy).

If your G4 receiver suddenly craps out, sound-wise, call the hotline number and have a new one sent out.  Alarms that won’t alarm are alarming.

(* I follow myself on the Dexcom Follow app, along with one other person.  Yes, redundant.  In response to the dead receiver speaker, I changed the alarm settings on my phone so that I’d be alerted for highs and lows.  This worked, in theory, except when my phone was on silent or in the other room.)

Rasharoni.

As this pregnancy continues on, so does the rapid rounding-out of my abdomen (today’s issue = not being able to zip my jacket without over-taxing the zipper). Feeling quite like Violet Beauregard from Charlie and the Chocolate Factory.

Pluses to this expansion are that a. the pregnancy is progressing on schedule and b. the real estate options for my pump site and Dexcom sensor are literally broadening.  Which is useful, since my adhesive rash is in full rawr mode.

In response to rashes that are taking weeks to heal properly (they aren’t oozing or anything gross, but a particularly cold day or a too-hot shower will make the area where the sensor and any tape was get madly scaly, red, and itchy), I’ve needed to really mix up where my diabetes devices are applied.  I put a sensor on my lower left-side abdomen for the first time in almost a decade and it hurt like hell going in but did not leave a residual rash when I removed it.

New skin holds up better than my favored spots, but with only seven days of wear and an aversion to abdomen sites, it’s getting tricky.  At the Friends for Life Falls Church conference in DC this past weekend, there was discussion in several groups about rash strategies, but I can’t recall everything that everyone said.  (If you have tips on dealing with skin irritation, please share them!)

I am seeing a dermatologist again this week to see if they can offer any relief/advice/assistance, so there is hope.  For now, Toughpads, DermaSarra lotion, and site rotation are my best defense.  Because hope remains an itch I refuse to scratch … especially when there are so many other bits of me that need scritch-scratching.
