It allows you to attempt to “catch” high and low blood sugars before they occur.
This is useful if it’s been hours since you’ve taken insulin, or you are on a low number and are about to take part in some form of physical activity. This trend indicates whether your glucose may rise, go down, or stay steady. When you move the reader over the sensor, it shows up a current glucose reading and the last eight hours of data as well as a trend arrow. This is a handheld reader (as shown below) that shows your glucose readings and can store the data for up to 90 days, which gives you the chance to analyze patterns and trends. The FreeStyle Libre System has two main pieces. (two stacked quarters in the USA) The sensor lasts up to fourteen days. This is all achieved by wearing a sensor on your arm, which is the size of a two pound (UK) coin. This reduces the need for countless finger pricks and the system can indicate via a graph whether your blood sugar is rising, dropping or heading steadily.
What this basically means is that the FreeStyle Libre is a system that allows you to “scan” your blood sugar using either a reader or an app on a smartphone.
So, to take an official quote from the Abbot website: “The FreeStyle Libre flash glucose monitoring system is the first product in the flash glucose monitoring category and is designed to liberate people with diabetes from many of the hassles of glucose monitoring, such as routine finger pricking.” Some of you may have already heard of the FreeStyle Libre Sensor, others may not. What is the FreeStyle Libre Sensor and System?
