What is the Freestyle sensor for? Complete guide

Having diabetes does not have to mean a limited life. Nowadays, there are solutions that make glucose monitoring much easier, faster, and more comfortable. One of the most popular is the FreeStyle Libre sensor. If you want to know what the FreeStyle sensor is and what it is for, you are in the right place. 

In this complete guide, we clearly and friendly explain everything you need to know about this device, how to use it, who it is designed for, and what advantages it offers.

What is the FreeStyle sensor?

The FreeStyle Libre sensor is a continuous glucose monitoring (CGM) device. It is placed on the back of the arm and measures glucose levels in the interstitial fluid without the need for constant finger pricks. It is small, discreet, water-resistant, and lasts up to 14 days.

Additionally, it is compatible with mobile applications like FreeStyle LibreLink (for the user), LibreLinkUp (for caregivers), and LibreView (for healthcare professionals). These allow easy and quick monitoring and analysis of glucose data anytime and anywhere.

This system was designed by Abbott Laboratories to facilitate the control of type 1 and type 2 diabetes. Currently, there are new versions, such as the FreeStyle Libre 2 and FreeStyle Libre 2 Plus, each with improved features.

What is this sensor for?

This type of technology significantly improves the quality of life for those living with diabetes, as it allows constant, precise, and uninterrupted monitoring. Its main function is to measure glucose levels in real time and send them directly to your mobile through the FreeStyle LibreLink app. 

Thanks to its smart alarms, it notifies you when glucose levels are too high, too low, or if the signal is lost. This allows you to have continuous control without needing to scan or prick yourself multiple times a day. 

Additionally, the sensor allows detecting glucose patterns and facilitates better decision-making. This way, you can act quickly and avoid dangerous hypoglycemia or hyperglycemia. Especially for those who need to adjust insulin doses or plan meals and exercise.

Who the FreeStyle Libre sensor is designed for

The FreeStyle sensor is indicated for:

• People with type 1 and type 2 diabetes.

• Adults, young people, and children from 2 years old.

• Users who want greater control of their glucose without pricking themselves several times a day.

• Active people who need to measure their glucose during exercise or water activities.

• Caregivers or parents who want to be informed at all times about their children's glucose levels (with the LibreLinkUp app).

• Patients with unrecognized hypoglycemia or fear of sudden drops in blood sugar.

How to use the FreeStyle sensor correctly

Using the FreeStyle sensor correctly is much easier than it seems:

1. It is applied to the back of the arm with an automatic applicator. It is painless and quick.

2. It can be activated with a reader or with the FreeStyle LibreLink app. From that moment, it starts recording data.

3. With the FreeStyle Libre 2 or 2 Plus sensor, readings are sent automatically to the mobile phone.

4. After 14 or 15 days, it is necessary to replace the sensor with a new one.

5. Protect your FreeStyle sensor with hypoallergenic, decorative, and water-resistant patches offered by Glucody. They help keep it in place even during sports or showering.
