What Is Freestyle Libre?

The Freestyle Libre is a continuous glucose monitoring (CGM) system designed for people with diabetes. It consists of a small sensor placed on the skin’s surface that measures glucose levels in the interstitial fluid. 

Unlike traditional glucose monitoring, it doesn’t require fingerstick blood tests, making it more convenient and less invasive. 

Users can scan the sensor with a reader or smartphone to instantly view their current glucose levels, historical data, and trends. 

This real-time information helps individuals with diabetes manage their condition more effectively by making informed decisions about diet, exercise, and insulin dosing. 

The Freestyle Libre has revolutionized diabetes management, offering greater freedom and improved quality of life for those living with the condition.

How Does Freestyle Libre Sensor Work?

The Freestyle Libre sensor works based on a technology called continuous glucose monitoring (CGM). Here’s how it works:

Sensor Placement

The Freestyle Libre sensor consists of a small, disposable, and flexible wire-like filament that is inserted just under the skin, typically on the back of the upper arm. 

This process is done using an applicator and is relatively painless.

Interstitial Fluid Measurement

Once placed, the sensor measures glucose levels in the interstitial fluid, which is the fluid that surrounds the body’s cells. Glucose levels in the interstitial fluid closely mirror those in the bloodstream.

Data Collection

The sensor continuously monitors glucose levels and records this information at regular intervals, usually every few minutes.

Scanning or Reader

To access the data, users can either scan the sensor using a dedicated Freestyle Libre reader or a compatible smartphone with the Freestyle LibreLink app. 

This scanning process is done by holding the reader or smartphone near the sensor.

Glucose Readings

When scanned, the sensor transmits the glucose readings to the reader or smartphone, displaying the current glucose level, historical data, and trends on the screen.

Real-Time Monitoring

Users can see their glucose levels in real-time, enabling them to make immediate decisions about managing their diabetes, such as adjusting their diet, exercise, or insulin doses.

Data Storage

The Freestyle Libre system typically stores glucose data for up to 8 hours, allowing users to track patterns over time.

Why Does My Freestyle Libre Keep Falling Off?

The Freestyle Libre sensor staying securely in place is essential for accurate and continuous glucose monitoring. 

If your Freestyle Libre sensor keeps falling off, there could be several reasons for this issue, and here are some common solutions to help keep it in place:

Proper Placement

Ensure that the sensor is placed on a clean, dry, and hair-free area of your skin. Oily or hairy skin can make it difficult for the sensor adhesive to stick.

Clean Skin

Clean the application site with mild soap and water, and ensure it’s thoroughly dry before applying the sensor. Avoid using lotions, creams, or oils on the site.

Adhesive Prep

Some users find success by using an adhesive barrier wipe or spray on the skin before applying the sensor. This can help create a better bond between the sensor adhesive and your skin.

Secure Application

Make sure you apply the sensor correctly using the provided applicator, and press down firmly to ensure it sticks well. Hold it in place for a few seconds after application to let the adhesive bond.

Skin Type

Individuals with very dry or sensitive skin may encounter more difficulty with sensor adhesion. If this is the case, consult with your healthcare provider for recommendations or alternatives.
