Using the LIBRE 3 for Glucose Control While On Dialysis

We laid out the need for continuous tight diabetic control both before and subsequent to going on dialysis in previous blogs. While a pain in the rear, it is something that diabetics in general, and those with DKD (Diabetic Kidney Disease) MUST deal with.

In general, there are two ways to ascertain one’s degree of diabetic control, either via pricking the skin, gathering a blood sample with a test strip, and reading the resulting glucose with a device. Of course you could go to a lab, have blood drawn, and receive standardized results in a few days. 

The second and more recent methodology is via a CGM (Continuous Glucose Monitor.) Yesterday I blogged about a third emerging methodology embedded in watches. I am currently using the Libre 3 Freestyle by Abbott and a watch. It is a follow on to their Libre 2 system which I also used for three months and is a vast improvement in many ways. BTW, Libre comes from the Latin word līber, via the French and Spanish libre; it shares that root with liberty. It denotes “the state of being free”, in the sense of “having freedom” or “liberty”. I’m certain in a marketing sense the word Libre somehow applies herein.

The Libre 3 system is more accurate, does not require an external reader, has an improved app, provides more or less continuous readings, and also provides a form of A1c readings named GMI (Glucose Management Indicator in mmol/mol%) as compared to its predecessor. It is night and day superior to finger pricks. While this is not a sales pitch for this system, it should be recognized that there are several competing products available; I’m just hands-on with the Libre. A quick Google will extoll its virtues for those interested. 

Following are some screenshots of what I consider to be useful from Libre3. I use it daily, probably at least six times a day to check my glucose levels. It is often surprising how the body reacts from a glucose viewpoint to the intake of food and beverages and exercise. Just getting up in the morning results in a rising glucose level. It should also be noted that I pay for the Libre 3 system out-of-pocket. Since I take insulin only once a day, currently 8 units of Lantus, I am not eligible for ANY insurance support be it Medicare, Tricare For Life, or VA. It is costing me roughly $210/month for two senders which last 14 days per sender. To me it is more than worth the cost.

The Case for Strong Diabetic Control Before and While On Dialysis Using the E400 Smart Watch

A strong case has been made in a preponderance of reviewed medical journals that diabetes is the primary and number one predictor of a future requirement to go on dialysis. See stats in the table below from CDC here: The extreme need for close diabetic control does not end once a person goes on dialysis; if anything, because PD at a minimum requires dumping a sugar solution into one’s stomach, it becomes even more critical.

  • For adults with diagnosed diabetes:
    • 69% had high blood pressure, and 44% had high cholesterol.
    • 39% had chronic kidney disease, and 12% reported having vision impairment or blindness.
    • Diabetes was highest among Black and Hispanic/Latino adults, in both men and women.

This blog is not about the how-to of diabetic control, but about one of the new tools just hitting the market to ascertain the degree of control, that is, how is my “blood sugar/glucose doing?”

Coming out of China is a new class of wearable devices in the form of a wristwatch at a very reasonable price called smart watches, or bio watches. They are generally available from Temu.com/App, Aliexpress.com, etc. for about $40.00. I have purchased two from Temu.com via their App for $39.62. See the Graphic below for all they are purported to be able to measure from here: The watches are based on the GR5515 chip and are Model E400 from Vanssa in China.

E400 Functions

I have been using the watch’s many functions in parallel with my go-to standard blood pressure, O2, temperature, and glucose (I use the Libre 3 CGM) as comparisons. I find some of the readings to be right on, and others to be somewhat consistent. It should be pointed out that the documentation that comes with the device explicitly states they are NOT to be used for medical purposes – yet I might add. As the video describes below, they are great for trends. I have found the E400 watch to be a great addition to a bag of tools for the diabetic/person on dialysis used in conjunction with the associated H Band App. Please watch the video embedded below for an independent review of the E400.

My next blog will discuss using the Libre 3 CGM for diabetic control while on dialysis.
