The Dexcom G6 CGM System helps you know your glucose number and where it's headed with the Dexcom G6 Continuous Glucose Monitoring (CGM) System - FDA-permitted for making diabetes treatment decisions with zero fingersticks and no calibration
What is Continuous Glucose Monitoring (CGM)?
Continuous Glucose Monitoring (CGM) is a method to track glucose levels throughout the day and night. CGM systems take glucose measurements at regular intervals, 24 hours a day, and translate the readings into dynamic data, generating glucose direction and rate of change.
Having this context helps CGM users proactively manage glucose highs and lows, plus gives added insight into impacts that meals, exercise and illness may have on an individual’s glucose levels. CGM can also contribute to better diabetes management by helping to minimize the guesswork that comes with making treatment decisions* based solely on a number from a blood glucose meter reading.
Studies have shown that some CGM systems may help reduce A1C and reduce the risk for hypoglycemia, whether users are on insulin injections or pump therapy
What is the difference between CGM and BGM?
Blood Glucose Meters (BGM) measure glucose levels at a single moment in time, while Continuous Glucose Monitoring (CGM) systems continually check glucose levels throughout the day and night.
BGMs are only capable of generating a single glucose level reading, while CGM systems use data gathered over the course of an entire day and night.
Since CGM systems collect measurements 24/7, they provide dynamic information about the direction of glucose levels and rate of change. This level of proactivity is not possible with BGMs.
CGM has proved to be the best outpatient glycemic management system for reducing A1C
CGM systems help to minimize the guesswork that comes with making treatment decisions based solely on a number from a blood glucose meter reading.
The way measurements are taken is different between the two methods. BGMs require a fingerstick while CGMs place a sensor under the skin while connecting to a transmitter which continuously sends regular intervals of glucose readings to a receiver or compatible smart device via Bluetooth technology.
Unlike BGMs that require deliberate action to get a reading, real-time CGM systems work throughout the night, while the user is asleep.
