  Interested to learn more about Continuous Glucose Monitoring? Continuous Glucose Monitoring (CGM) systems track glucose levels throughout the day. CGM users insert a tiny sensor wire just under their skin using an automatic applicator. An adhesive patch holds the CGM sensor housing in place so the sensor can measure glucose readings in interstitial fluid throughout the day and night.    Just as in life, the Continuous Glucose Monitoring arena is full of choices.  The brands have unique features that make them better choices for different people.  Below is a comparison with the pros and cons of some of the CGMs now available.       FreeStyle Libre   Dexcom G6   Medtronic Guardian III Available Online!   Available Online!         --

What is CGM and How Does it Work? Continuous Glucose Monitoring (CGM) systems track glucose levels throughout the day. CGM users insert a tiny sensor wire just under their skin using an automatic applicator. An adhesive patch holds the CGM sensor housing in place so the sensor can measure glucose readings in interstitial fluid throughout the day and night.    A small, reusable transmitter connects to the sensor wire and sends real-time readings wirelessly to a receiver, so the user can view the information. With some systems, a compatible smart device (cell phone) with the CGM system app can serve as the display device. The receiver or compatible smart device displays current glucose levels, as well as historical trends in levels. Unlike a blood glucose meter (BGM), which provides just a single glucose reading, CGM systems can provide real-time, dynamic glucose information every five minutes — up to 288 readings in a 24-hour period.  Users can gain valuable
