Continuous Glucose Monitoring (CGM) systems are advanced devices designed to monitor glucose levels in real-time throughout the day and night. These systems offer a significant advantage over traditional glucose monitoring methods, such as fingerstick testing, by providing continuous data without the need for frequent manual measurements.
How Does a CGM System Work?
CGM systems consist of three main components: a small sensor placed under the skin, a transmitter that sends data to a receiver or smartphone app, and a display device that shows glucose readings and trends. The sensor measures glucose levels in the interstitial fluid and transmits this data to the receiver, allowing users to track their glucose levels continuously.
Features and Benefits of Freestyle Libre 2 Plus Sensor
The Freestyle Libre 2 Plus Sensor offers several features and benefits that make it a popular choice among individuals with diabetes.
Accuracy and Reliability
One of the key advantages of the Freestyle Libre 2 Plus Sensor is its accuracy and reliability in measuring glucose levels. Clinical studies have demonstrated that the sensor provides accurate readings comparable to traditional fingerstick testing.
Ease of Use
The Freestyle Libre 2 Plus Sensor is designed for ease of use, with a simple application process and intuitive interface. Users can easily apply the sensor to the back of their upper arm and scan it with a compatible reader or smartphone to obtain glucose readings.
Alarms and Alerts

Difference Between Freestyle Libre 2 and Freestyle Libre 2 Plus Sensor
While both sensors offer continuous glucose monitoring, the Freestyle Libre 2 Plus Sensor includes additional features such as customizable alarms and alerts, making it a more advanced option for managing diabetes.
Who Can Benefit from Freestyle Libre 2 Plus Sensor?
The Freestyle Libre 2 Plus Sensor is suitable for individuals with type 1 and type 2 diabetes who require continuous monitoring of their glucose levels.
Type 1 Diabetics
Individuals with type 1 diabetes can benefit from the Freestyle Libre 2 Plus Sensor’s continuous glucose monitoring capabilities, helping them manage their blood sugar levels more effectively and reduce the risk of hypo- or hyperglycemia.
Type 2 Diabetics
Type 2 diabetics can also benefit from the Freestyle Libre 2 Plus Sensor, particularly those who require insulin therapy or have difficulty maintaining stable blood sugar levels.
How to Use Freestyle Libre 2 Plus Sensor
Using the Freestyle Libre 2 Plus Sensor is simple and straightforward, with the following steps:
Application Process
- Clean the application site on the back of the upper arm with an alcohol wipe.
- Remove the sensor applicator from the packaging and place it on the skin.
- Press the button on the applicator to insert the sensor under the skin.
- Remove the applicator and ensure the sensor is securely in place.
Insertion and Wear Time
The Freestyle Libre 2 Plus Sensor can be worn for up to 14 days before needing replacement. Users should follow the manufacturer’s instructions for sensor placement and replacement to ensure accurate readings.
Cost and Availability of Freestyle Libre 2 Plus Sensor
The cost of the Freestyle Libre 2 Plus Sensor may vary depending on factors such as insurance coverage and location. Many insurance plans cover all or part of the cost of the sensor, making it more accessible to individuals with diabetes. Additionally, the sensor is available for purchase online and at pharmacies with a prescription.
User Reviews and Feedback
User reviews of the Freestyle Libre 2 Plus Sensor are generally positive, with many users praising its accuracy, ease of use, and convenience. However, some users have reported issues such as skin irritation or difficulty obtaining accurate readings in certain situations.
Comparison with Other CGM Systems
While the Freestyle Libre 2 Plus Sensor offers several advantages, it is essential to compare it with other CGM systems on the market.
Dexcom G6
The Dexcom G6 is another popular CGM system known for its accuracy and reliability. Unlike the Freestyle Libre 2 Plus Sensor, the Dexcom G6 requires no fingerstick calibrations and offers predictive alerts for high and low glucose levels.
Medtronic Guardian Sensor 3
The Medtronic Guardian Sensor 3 is another CGM system that offers continuous glucose monitoring. It features advanced algorithms for predicting glucose trends and customizable alerts for hyper- and hypoglycemia.
Future Developments and Upgrades
As technology continues to advance, we can expect further developments and upgrades to CGM systems like the Freestyle Libre 2 Plus Sensor. These may include improvements in accuracy, sensor longevity, and integration with other diabetes management technologies.
Tips for Maximizing the Benefits of Freestyle Libre 2 Plus Sensor
To get the most out of your Freestyle Libre 2 Plus Sensor, consider the following tips:
- Ensure proper sensor placement and adherence to minimize the risk of inaccurate readings.
- Calibrate the sensor as needed according to the manufacturer’s instructions.
- Stay vigilant with monitoring glucose levels and responding to alarms or alerts promptly.
Potential Risks and Side Effects
While the Freestyle Libre 2 Plus Sensor is generally safe and well-tolerated, some users may experience minor side effects such as skin irritation or allergic reactions to the adhesive. In rare cases, the sensor may provide inaccurate readings, leading to potential mismanagement of blood sugar levels.
Conclusion
The Freestyle Libre 2 Plus Sensor offers an advanced solution for continuous glucose monitoring, providing individuals with diabetes greater insight into their blood sugar levels and improved management of their condition. With features such as customizable alarms and ease of use, it has become a popular choice among users seeking to optimize their diabetes management regimen.
