Abbott Freestyle Libre 3 CGM for diabetics

  • For 25 years, I’ve had Type 1 diabetes. Like the tens of tens of millions of Americans with diabetes, one of the crucial necessary issues I’ve to do to remain wholesome is be sure that my blood sugar is in regular vary.

Continuous glucose displays (CGMs) permit diabetics to trace their blood sugar 24/7. They’re extremely helpful, offering perception on how your blood sugar reacts to insulin, meals, train and no matter else impacts it.

(*3*)Abbott Laboratories and Dexcom are the leaders within the CGM market, which hit $5.1 billion in income in 2021 and is predicted to succeed in $13.2 billion by 2028, in response to Vantage Market Research. Abbott’s CGM programs, referred to as FreeStyle Libre, generated $3.7 billion in income final yr, with 4 million customers globally.

Abbott has simply launched its latest CGM, the FreeStyle Libre 3. It comes with an necessary improve. Whereas the earlier programs have been “flash” CGMs, which implies you needed to maintain your reader or telephone near the sensor to get a studying, the brand new model sends knowledge straight to your telephone.

I attempted it out for over a month. Here are my takeaways:

How it really works

The insertion machine is available in a small field and is slightly compact. The Libre 3 is simply authorised by the Food and Drug Administration to enter the arm. The insertion was painless, and the sensor itself is tiny in comparison with others I’ve used.

The app requires a scan of the sensor, after which it takes 60 minutes to heat up. During the primary 12 hours, a blood drop icon will seem.

Abbott says the sensor is acclimating. It additionally advises utilizing a blood glucose meter to make sure the sensor is correct. I discovered that it was correct instantly, even whereas it was warming up.

The sensor stays on for 14 days. It provides a brand new studying each minute, in comparison with a studying each 5 minutes from the Dexcom G6. The adhesive labored effectively and confirmed no signal of falling off after two weeks. It nonetheless does not require finger sticks or calibration.

The development arrows inform you in case your glucose is regular, rising or falling. The alarms are customizable. If you wish to silence high and low alerts, you should utilize the app’s “do not disturb” perform. The pressing low alarm cannot be silenced, as required by the FDA.

The app has some helpful options for monitoring common glucose and time in vary and offers you the choice to share the information with family members. It additionally has a experiences characteristic that provides you insights into patterns so you may make dosage changes. 

The Libre 3 is small and correct

I like how small it’s, so small in reality that I stored forgetting I used to be carrying it. I put my Dexcom G6 close by to match. There’s an enormous distinction.

It was correct more often than not. But I discovered that in instances of speedy change, corresponding to after I forgot to take my insulin after a meal, it grew to become inaccurate and had a tough time maintaining.

I did have two compression lows with the primary sensor. A compression low is when the sensor provides an incorrect low studying. One occurred whereas I used to be sleeping on my aspect, and the opposite was whereas I used to be sitting on the sofa and leaning on the sensor. I readjusted, and the machine shortly corrected itself. I made certain to decide on a greater placement for the second sensor.

The app might be improved

In the app, you’ll be able to’t customise the graph measurement. It exhibits a spread of fifty mg/dL to 350 mg/dl. I’d like the power to regulate that so it is just a little tighter, as a result of my blood sugar not often goes above 250 mg/dl, so there’s lots of wasted area.

There’s additionally no skill to zoom into previous readings. Sometimes when I’m low I like to have the ability to zoom in and see how shortly the quantity is altering. And whereas it does ship notifications to my iWatch, Abbott does not but have an app appropriate to make use of with it, so seeing your blood sugar in your watch is not attainable. Abbott says it is one thing they’re engaged on for the long run.

Prescription required, worth varies

The Libre 3 requires a prescription, so the associated fee might be completely different for everybody. Abbott mentioned customers with insurance coverage can count on to pay $0-$25 per sensor and $70 per sensor with out insurance coverage. You’ll want to purchase two a month.

Would I like to recommend this to different diabetics? Yes, however it depends upon the consumer. For diabetics like me who use insulin pumps, the Libre 3 is not appropriate but. Abbott mentioned it is engaged on pump integration with Tandem Diabetes and Insulet. The firm can be working with Bigfoot Biomedical on integration with its insulin supply system.

For diabetics who depend on guide insulin injections or who food plan to handle their diabetes, it is a nice solution to monitor blood sugar.
