The Difference Between Dexcom and FreeStyle Sensors

In the realm of diabetes management, continuous glucose monitoring (CGM) systems have revolutionized the way individuals monitor their blood sugar levels. Two prominent players in this field are Dexcom and FreeStyle, each offering innovative sensor technologies designed to provide real-time insights into glucose fluctuations. 


Understanding the nuances and differences between these systems is crucial for individuals seeking the most effective solution for their unique needs. Here, we'll delve into the disparities between Dexcom and Freestyle sensors, exploring their features, functionality, and how they impact the lives of those managing diabetes! 


Comparing Continuous Glucose Monitoring Systems 


Dexcom and FreeStyle sensors are both continuous glucose monitoring (CGM) systems that provide real-time data on glucose levels throughout the day and night. They offer users the ability to track trends, receive customizable alerts for high and low glucose levels, and make informed decisions about insulin dosing, diet, and exercise to better manage their diabetes.


Some of the key differences between Dexcom and FreeStyle sensors include: 


  • Sensor Technology:
    • Dexcom sensors utilize a thin, flexible wire inserted under the skin to measure glucose levels.
    • FreeStyle sensors employ a small, round sensor placed on the back of the upper arm, using a filament to measure glucose levels in the interstitial fluid.
  • Calibration:
    • Dexcom sensors typically require calibration with fingerstick blood glucose readings multiple times per day.
    • FreeStyle sensors are factory-calibrated and do not require routine fingerstick calibrations, offering convenience to users.
  • Compatibility:
    • Dexcom sensors are compatible with a variety of insulin pumps and diabetes management software platforms.
    • FreeStyle sensors are primarily designed for use with Abbott's Freestyle Libre reader and smartphone apps, with limited compatibility with other devices.
  • Alerts and Alarms:
    • Dexcom sensors offer customizable alerts for high and low glucose levels, allowing users to adjust settings based on individual preferences and needs.
    • FreeStyle sensors provide optional alarms for high and low glucose levels, but the level of customization may be more limited compared to Dexcom.
  • Data Sharing:
    • Dexcom sensors enable remote sharing of glucose data with caregivers or healthcare providers via compatible apps and cloud-based platforms.
    • FreeStyle sensors may have limited or no built-in data-sharing capabilities, depending on the specific model and software version.
