Managing diabetes effectively requires accurate and continuous glucose monitoring. Choosing the right Continuous Glucose Monitor (CGM) can significantly impact a person's ability to maintain stable glucose levels and improve overall well-being. Two popular CGM systems are the Freestyle Libre and Eversense CGM, each offering unique benefits suited to different lifestyles.
This article provides a detailed comparison of these two CGMs, helping you determine which one best suits your needs.
Overview of Freestyle Libre
The Freestyle Libre is one of the most widely used CGMs worldwide. Manufactured by Abbott, it is designed to be an accessible and easy-to-use glucose monitoring system.
Key Features:
- Sensor lifespan: Up to 14 days (Freestyle Libre 2 & 3).
- No calibration needed: Unlike some CGMs, Freestyle Libre does not require regular fingerstick calibrations.
- Real-time glucose tracking: The Freestyle Libre 3 provides continuous glucose readings directly to a smartphone.
- Affordable: Comparatively lower in cost than some CGMs, making it accessible to a wider audience.
Ideal For:
- Individuals seeking a budget-friendly, non-invasive monitoring system.
- Those who prefer a CGM with minimal maintenance and no calibration requirements.
Overview of Eversense CGM
The Eversense CGM, developed by Senseonics, is the first and only implantable CGM available. Unlike traditional CGMs that require adhesive sensors applied to the skin, Eversense is inserted just under the skin by a healthcare professional.
Key Features:
- Sensor lifespan: 180 days (approximately 6 months), significantly longer than other CGMs.
- Calibration required: Requires fingerstick calibrations twice daily.
- Real-time alerts: Provides on-body vibrational alerts, ideal for hypo- and hyperglycemia warnings.
- Smartphone integration: Data is continuously sent to a mobile device for tracking and alerts.
Ideal For:
- Tech-savvy users who prefer long-term solutions with fewer sensor changes.
- Those comfortable with minor surgical procedures for insertion and removal.

Pros and Cons of Freestyle Libre vs Eversense
Freestyle Libre
Pros:
- Affordable and widely accessible.
- No calibration required.
- Easy to apply and remove.
Cons:
- Shorter sensor lifespan (up to 14 days).
- Limited real-time alerts (especially in earlier models).
Eversense CGM
Pros:
- Long sensor lifespan (6 months, reducing frequent replacements).
- Vibrational alerts for glucose fluctuations.
- No adhesive-related skin irritation since it is implanted under the skin.
Cons:
- Requires a minor surgical procedure for insertion and removal.
- More expensive due to the medical procedure and ongoing calibration needs.
Who Should Choose What?
Choosing between Freestyle Libre and Eversense CGM depends on individual needs and preferences.
Freestyle Libre is best for:
- Those looking for an affordable, user-friendly CGM.
- Individuals who prefer to avoid calibration and medical procedures.
Eversense is best for:
- Users who want a long-term CGM solution with fewer sensor changes.
- Those who require frequent alerts for better glucose management.
Conclusion
Both Freestyle Libre and Eversense CGM offer unique benefits, making them valuable tools for diabetes management. The right choice depends on personal preferences, budget, and lifestyle needs.
For those seeking affordability and simplicity, Freestyle Libre is an excellent option. For users wanting longer wear time and advanced alerts, Eversense is worth considering.
