Introduction

Continuous Glucose Monitoring (CGM) systems have revolutionized diabetes management by providing real-time glucose readings to individuals. Two popular CGM systems in the market are the Freestyle Libre 3 and Dexcom G7. While both devices serve the same purpose, there are key differences that users should be aware of. In this article, we will explore the distinctions between Freestyle Libre 3 vs Dexcom G7, helping you make an informed decision about which CGM system suits your needs best.

Sensor Technology

The sensor technology used in CGM systems is crucial in determining accuracy and ease of use. The Freestyle Libre 3 utilizes a small, round sensor that is applied to the back of the upper arm. This sensor measures glucose levels in the interstitial fluid, which correlates with blood glucose levels. The sensor is factory-calibrated, meaning it does not require manual calibration with fingerstick blood glucose readings.

In contrast, the Dexcom G7 employs an advanced sensor design that is even smaller than the previous Dexcom models. The G7 sensor is worn on the abdomen and uses a thin filament to measure glucose in the interstitial fluid. Similar to the Freestyle Libre 3, the Dexcom G7 is also factory-calibrated, eliminating the need for routine fingerstick calibrations.

Data Accessibility

Accessing and interpreting glucose data is a vital aspect of CGM systems. With the Freestyle Libre 3, users can obtain glucose readings by scanning the sensor using a handheld reader or a compatible smartphone. The scanned data provides real-time glucose readings, trends, and historical data, empowering users to make informed decisions about their diabetes management.

On the other hand, Dexcom G7 utilizes a transmitter that wirelessly sends glucose data to the Dexcom G7 receiver or a smartphone app. The Dexcom G7 system offers continuous glucose readings, customizable alerts for high and low glucose levels, and the ability to share data with healthcare professionals or loved ones through secure cloud-based systems.

Wear Duration and Sensor Replacement

The wear duration and ease of sensor replacement are important considerations for CGM users. The Freestyle Libre 3 sensor has a wear duration of up to 14 days, after which it requires replacement with a new sensor. Sensor replacement is a straightforward process that can be done by the user at home.

In contrast, the Dexcom G7 sensor is designed for a wear duration of up to 10 days. Similar to the Freestyle Libre 3, the sensor replacement process for Dexcom G7 is user-friendly, allowing for at-home replacement.

Cost and Insurance Coverage

The cost and insurance coverage of CGM systems can vary. It is essential to consider these factors when choosing between the Freestyle Libre 3 and Dexcom G7. The actual cost depends on individual insurance plans, but generally, both systems involve costs for the sensor and the reader or transmitter.

Insurance coverage for CGM systems has been expanding, with many plans offering coverage for individuals with diabetes. It is advisable to check with your insurance provider to determine the coverage details for the Freestyle Libre 3 and Dexcom G7.

If you want to buy the Dexcom G7 or the Freestyle Libre 3 buy online then you should get them from a trusted and verified seller.

Conclusion

In conclusion, the Freestyle Libre 3 and Dexcom G7 are two leading CGM systems that offer valuable glucose monitoring capabilities. The choice between the two depends on individual preferences and needs. Factors such as sensor technology, data accessibility, wear duration, and cost should be considered when making a decision. Consult with your healthcare provider to determine which CGM system aligns with your diabetes management goals and lifestyle.
