Tangled and Intertwined: Diabetes and Covid-19

A while back I started a blogpost with the words “tangled” and “intertwined.” The emotions prompting those words were powerful but I abandoned the post in favor of laziness.

Last Saturday I “attended” a virtual session at Friends for Life Orlando titled “Avoiding and Overcoming Diabetes Burnout.” The moderators were William Polonsky, PhD, CDE and Kerri Sparling. Partway through the session Kerri mentioned something about her diabetes and coronavirus being iinseparable and I thought “yes!” That is what I had originally been planning to write about. No doubt if Kerri were still blogging, she would say it better than I will, but we likely have the same thoughts muddling through our brains.

A lot of my musings go back to late January when I began using Dexcom G6 and Basal IQ on my Tandem X2 pump followed by Control IQ. I was on Control IQ for less than six weeks when the coronavirus invaded my world. For those of you not knowledgeable about diabetes tech, Control IQ is defined by Tandem Diabetes:

ControlIQ technology is an advanced hybrid closed-loop system that uses an algorithm to automatically adjust insulin in response to predicted glucose levels to help increase time in the American Diabetes Association-recommended target range (70-180 mg/dL).

I wrote a couple of blogposts about my early experiences with Control IQ and I don’t think that my opinions have changed a lot since the March post titled “Six Weeks: More Thoughts on Control IQ.” I am mostly okay with it and really appreciate the fact that I have almost zero low blood sugars. But my average blood sugar is higher than pre-Control IQ and I am frustrated that I am required to use Tandem’s conservative BG goals instead of the targets that I prefer. In general I am still trying to figure out how to lower my average blood sugar without constant suspensions of insulin that result in sticky highs later on. Some people on Facebook seem to do that successfully and post daily graphs that don’t make sense to me based on my experiences. At a late May appointment I questioned my endocrinologist on whether she had any suggestions, and she said “No. Control IQ is doing what it is supposed to do and you are doing great.”

And she is right. But diabetes is never independent of mental health and I struggle to accept the new numbers when I liked the old numbers and don’t completely understand the new numbers. But the old numbers reflected many low blood sugars and a lot of glucose tabs. At the same time the new numbers don’t display what I think the Sleep Mode of Control IQ should target. I have never experienced classical diabetes burnout but my diabetes is mucked up with anxiety, perfection, lack of perfection, unattainable goals, and just plain never-getting-a-vacation.

In the last paragraph I introduced “mental health.” Enter Coronavirus. I am 68 years old and have lived with diabetes for 43 years. I consider myself to be healthy but I deal with multitude autoimmune conditions. If I get diagnosed with Covid-19, I am probably doomed. But who knows? My self-destructive side just wants to get the virus and be done with it. Either die or hopefully recover with ongoing immunity. But don’t get worried. I am not attending Covid-19 parties and have recently started using InstaCart for grocery and Costco deliveries. 

But like every other person in the world, I mourn my former life. I miss fitness classes at the YMCA and reminisce about hanging out at McDonald’s drinking cheap Diet Coke while surfing the web and writing blogposts. I miss going to the movies. I long for lunch and coffee with friends. I desperately want to visit my Maryland grandchildren and currently accept the risk of outdoor babysitting the local grandkids. I am okay most days but about once a week I wake up with a black cloud over my head.

The black cloud is part coronavirus and part diabetes-Control IQ. I can’t untangle what is what and for sure I haven’t figured out a way to eliminate the occasional days that are plagued with pit-in-the-stomach sadness and frustration. I am totally cognizant of the fact that 42+ things influence blood sugar and that I will never be a “Perfect Diabetic.” I am fine most days but the wind periodically blows in black clouds that suffocate my normally optimistic view of life. 

I am sad. I am frustrated.

I am healthy. I am mostly happy.

I know that I live a privileged life. I have no worries about acquiring insulin, CGM sensors, and pump supplies. I have access to online fitness and yoga classes and live near safe walking trails. My husband is employed and at the moment we are safe financially. My children have jobs and their families are doing relatively well considering the stress of home schooling and few daycare resources. 

But when the black clouds park above my psyche, I can’t tell whether they are the result of diabetes or Covid-19.

It doesn’t matter.

In my world diabetes and Covid-19 are tangled and intertwined. 

Tandem Occlusion Alarms: The Last Post

I started using a Tandem t:slim X2 insulin pump in December 2016 and immediately began having occlusion alarms once or twice a week. I had never had occlusions in 12+ years of pumping with Medtronic and Animas and quickly discovered that the vast majority of these Tandem alarms were false. All I had to do was dismiss the alarm, resume insulin, and go about my day. I can count on one hand the number of times that the occlusions were real and required a cartridge and infusion set change. It takes more than one hand to count the times that I had an embarrassing blaring alarm in awkward situations such as the movies, yoga class, and restaurants.

If you do an online search for Tandem Occlusion Alarms, you will be linked to some of my older blogposts. People still contact me with questions about their occlusion problems and I figured it was time to update my experiences and thoughts.

Although some of my previous blogposts suggested that I had fixed the problem, I never found a permanent solution to false occlusion alarms with some of my X2 pumps. I was fortunate that I wasn’t someone who had multiple alarms a day requiring cartridge and infusion set changes. The alarms were annoying and I mostly learned to live with them. Occasionally I called Tandem out of frustration but after a while they had nothing new to tell me and no real solutions.

If you notice in the last paragraph I say “some of my X2 pumps.” I am on my fifth pump in 3-1/2 years. My first pump had occlusion alarms starting the first week and was eventually replaced due to a failed battery. The second pump did not have a single occlusion alarm during the month that I used it, but the t:button was defective. The third pump had lots of occlusion alarms and was replaced for that reason. The fourth pump had one to two occlusion alarms per week and I gave up on solving the problem. 

But then….

In January 2020 I started using Dexcom G6 and wanted to install the newest Basal IQ update. It was determined that I had one of the older pumps with software that was incompatible with the Basal IQ and Control IQ updates. So I got another replacement pump. Amazingly several months went by with no occlusion alarms. I didn’t change anything in my behavior, cartridge use, or infusion set type. Through luck of the draw I finally had a pump that was not prone to false occlusion alarms. In the last 6+ months I have had 3 occlusion alarms all probably attributable to bunched up tubing during a mealtime bolus. 

I have long believed that some Tandem pumps are more prone to occlusion alarms than others. Is it an overly sensitive sensor or a less than robust motor? I’m not an engineer and have no idea. I have more than once been annoyed by people online being virtuous that they aren’t getting occlusion alarms and that I must be doing something wrong. Some times I felt as though Tandem techs blamed me.

No, maybe it was just the pump.

If you’re dealing with occlusion alarms, the best place to start might be with some of the “best practices” recommended by Tandem support techs and other X2 users on Facebook. Some helped me, some didn’t, and some I refused to do.

Things to try:

  1. Use the case
  2. Don’t carry the pump in your pocket
  3. Keep the tubing outstretched while a bolus is delivering
  4. Change your cartridge every 3 days
  5. Use TruSteel infusion sets
  6. Use insulin types approved for Tandem pumps
  7. Document everything and work with your local rep to get a replacement pump
  8. Just accept occlusion alarms, restart insulin, and move on

I don’t necessarily do all of those things and some of them made no difference in the number of my occlusion alarms. With only one to two alarms a week, I got very good at #8 and just lived with the alarms. I currently wear my pump on my waistband with a Nite Ize clip and use TruSteel infusion sets with Novolog insulin. But that’s what I did with the 3rd and 4th pumps that had lots of occlusion alarms. I dislike the size and weight of the case and don’t use it. I don’t change my cartridge every three days although I change my infusion set every two days. I rarely hold the tubing straight during a bolus.

So I live with a mixture of best practices and bad practices. I used to get a lot of occlusion alarms and now I don’t.

What changed?

The pump.
