Continuous glucose monitoring (CGM) systems have become increasingly popular among people with diabetes who need to monitor their blood glucose levels regularly. G7 Dexcom and Freestyle Libre 3 are two of the most popular CGM systems available in the market today. In this article, we will provide a comprehensive comparison of the two systems, highlighting their features, advantages, and disadvantages.
G7 Dexcom
G7 Dexcom is a CGM system that continuously measures glucose levels in the interstitial fluid (the fluid between cells in the body). The system consists of a small sensor that is inserted under the skin and a transmitter that is attached to the sensor. The transmitter sends glucose data to a receiver or a smartphone app, which displays real-time glucose readings, trend data, and alerts.
Advantages of G7 Dexcom
Real-time glucose monitoring: G7 Dexcom provides real-time glucose readings every 5 minutes, allowing people with diabetes to monitor their glucose levels continuously.
Customizable alerts: G7 Dexcom allows users to set customizable alerts to notify them when their glucose levels are too high or too low.
No fingerstick calibrations: G7 Dexcom does not require fingerstick calibrations, making it easier and more convenient to use.
Disadvantages of G7 Dexcom
Expensive: G7 Dexcom is relatively expensive compared to other CGM systems available in the market.
Requires frequent sensor changes: G7 Dexcom sensors need to be replaced every 7-10 days, which can be inconvenient for some users.
Freestyle Libre 3
Freestyle Libre 3 is a flash glucose monitoring system that uses a small sensor attached to the back of the upper arm to measure glucose levels in the interstitial fluid. The sensor records glucose data every minute and stores it in the sensor. Users can scan the sensor with a handheld reader or a smartphone app to obtain glucose readings, trend data, and alerts.
Advantages of Freestyle Libre 3
No fingerstick calibrations: Freestyle Libre 3 does not require fingerstick calibrations, making it easier and more convenient to use.
Longer sensor life: Freestyle Libre 3 sensors last up to 14 days, which means less frequent sensor changes.
Cost-effective: Freestyle Libre 3 is relatively affordable compared to other CGM systems available in the market.
Disadvantages of Freestyle Libre 3
No real-time glucose monitoring: Freestyle Libre 3 does not provide real-time glucose readings, which means users need to scan the sensor to obtain glucose data.
Limited alarm options: Freestyle Libre 3 has limited alarm options, which may not be customizable to suit individual needs.
Comparison between G7 Dexcom and Freestyle Libre 3
Real-time glucose monitoring: G7 Dexcom provides real-time glucose readings every 5 minutes, while Freestyle Libre 3 requires users to scan the sensor to obtain glucose data.
Customizable alerts: G7 Dexcom allows users to set customizable alerts, while Freestyle Libre 3 has limited alarm options.
No fingerstick calibrations: Both G7 Dexcom and Freestyle Libre 3 do not require fingerstick calibrations.
Sensor life: G7 Dexcom sensors need to be replaced every 7-10 days, while Freestyle Libre 3 sensors last up to 14 days.
Cost: G7 Dexcom is relatively expensive compared to Freestyle Libre 3, which is more affordable.
Conclusion
Both G7 Dexcom and Freestyle Libre 3 are excellent CGM systems with their advantages and disadvantages. The choice between the two systems ultimately depends on the user's personal preferences and needs. G7 Dexcom is ideal for people who require real-time glucose monitoring and customizable alerts, while Freestyle Libre 3 sensor buy online is suitable for those who prefer a cost-effective and more convenient option.
It is worth noting that the accuracy of CGM systems may vary depending on several factors, such as the calibration technique, sensor placement, and individual differences in glucose metabolism. Therefore, users should always consult their healthcare providers before making any significant changes to their diabetes management plan.
In summary, G7 Dexcom and Freestyle Libre 3 are two of the most popular CGM systems available in the market today. While both systems have their unique features and limitations, they provide people with diabetes with a reliable and convenient way to monitor their glucose levels continuously. Ultimately, the choice between the two systems depends on individual needs, preferences, and budget.
