What is FreeStyle Libre 3?

FreeStyle Libre 3 is a continuous glucose monitoring (CGM) system developed by Abbott. Designed for people with diabetes, it offers real-time glucose monitoring without the need for traditional fingersticks. The sensor, which is the smallest and most discreet on the market, is worn on the upper arm and automatically sends glucose readings to a smartphone every minute. It provides users with a clear picture of their glucose trends, enabling them to make timely decisions about their diet, exercise, and medication.
