Continuous glucose monitoring (CGM) systems such as the Freestyle Libre 2 and Freestyle Libre 3 have revolutionized the management of diabetes. These devices offer real-time insights into blood sugar levels, empowering individuals with diabetes to make informed decisions about their health. In this comprehensive comparison, we will explore the pros and cons of the Freestyle libre 2 vs libre 3 , helping individuals with diabetes choose the right CGM system for their needs.
Understanding Freestyle Libre 2 and Freestyle Libre 3
Overview of Freestyle Libre 2
The Freestyle Libre 2 is a CGM system developed by Abbott Laboratories. It consists of a small sensor worn on the back of the upper arm, which continuously measures glucose levels in the interstitial fluid. The sensor communicates wirelessly with a handheld reader or smartphone app, allowing users to monitor their glucose levels conveniently.
Overview of Freestyle Libre 3
The Freestyle Libre 3 is the latest generation of CGM systems from Abbott Laboratories. Like the Freestyle Libre 2, it features a small sensor worn on the back of the upper arm for continuous glucose monitoring. However, the Freestyle Libre 3 offers several advancements over its predecessor, including enhanced accuracy, longer wear time, and optional real-time glucose alarms.
The main difference between libre 2 and 3 is that the Libre 3 offers enhanced accuracy, longer wear time, and optional real-time glucose alarms compared to the Libre 2.
