It consists of a small sensor placed on the back of the upper arm that measures glucose levels every minute and transmits the data to a compatible handheld device or smartphone app, eliminating the need for fingerstick tests.

Yes, the FreeStyle Libre 2 sensor is waterproof, suitable for activities like showering, swimming, and exercising. It can be worn continuously for up to 14 days before needing to be replaced, ensuring consistent glucose monitoring.

The FreeStyle Libre 2 app provides real-time glucose readings, optional alarms for low and high glucose levels, data sharing with healthcare providers and family members, trend arrows, and data reports to support informed diabetes management decisions.
