Introduction

Continuous glucose monitoring (CGM) systems have revolutionized diabetes management. They allow individuals with diabetes to monitor their blood glucose levels in real-time, without the need for constant fingersticks. Two popular CGM systems on the market today are the Freestyle Libre 3 and the Dexcom G7. Although they have similar functions, there is some difference between Freestyle Libre 3 and Dexcom G7.

  1. Sensor Wear Time: One of the most significant differences between the Freestyle Libre 3 and the Dexcom G7 is the sensor wear time. The Freestyle Libre 3 has a wear time of 14 days, while the Dexcom G7 can be worn for up to 10 days. This means that users of the Freestyle Libre 3 will need to change their sensor less frequently than those using the Dexcom G7.

  2. Sensor Placement: The Freestyle Libre 3 and the Dexcom G7 also differ in their sensor placement. The Freestyle Libre 3 sensor is a small patch that is applied to the back of the upper arm. The Dexcom G7, on the other hand, can be worn on either the back of the upper arm, abdomen, or thigh. This gives users more flexibility in where they choose to wear their sensors.

  3. Calibration: Another difference between the Freestyle Libre 3 and the Dexcom G7 is calibration. The Freestyle Libre 3 does not require any calibration, whereas the Dexcom G7 requires two calibrations per day. This means that users of the Freestyle Libre 3 can start using the system immediately after applying the sensor, without the need for additional steps.

  4. Accuracy: Both the Freestyle Libre 3 and the Dexcom G7 are highly accurate CGM systems. However, studies have shown that the Dexcom G7 may be more accurate than the Freestyle Libre 3, especially at lower glucose levels. This is an important consideration for individuals who experience frequent hypoglycemia.

  5. Price: Freestyle Libre 3 sensor buy online price is generally less than Dexcom G7 price. This may be an important factor for individuals who are paying out-of-pocket for their CGM system or who have limited insurance coverage.

Conclusion

Both the Freestyle Libre 3 and the Dexcom G7 are effective CGM systems that can improve diabetes management. However, they differ in wear time, sensor placement, calibration, accuracy, and price. Individuals with diabetes should carefully consider their needs and preferences when choosing a CGM system. Ultimately, the best system is the one that helps them achieve their glucose management goals and fits into their lifestyle.
