What is the Freestyle sensor for? Complete guide

Having diabetes doesn’t have to mean a limited life. Today, 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’s for, you’re 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 benefits 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 apps like FreeStyle LibreLink (for users), LibreLinkUp (for caregivers), and LibreView (for healthcare professionals). These apps allow easy and quick monitoring and analysis of glucose data anytime and anywhere.

This system was designed by Abbott Laboratories to make managing type 1 and type 2 diabetes easier. Currently, there are newer versions, such as the FreeStyle Libre 2 and FreeStyle Libre 2 Plus, each with enhanced features.

What is this sensor for?

This type of technology significantly improves the quality of life for people 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 phone through the FreeStyle LibreLink app. 

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

Additionally, the sensor detects glucose patterns and helps you make better decisions. This way, you can act quickly and avoid dangerous hypoglycemia or hyperglycemia. Especially useful 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 intended 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 multiple times a day.

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

• Caregivers or parents who want to stay 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 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 your phone.

4. After 14 or 15 days, the sensor needs to be replaced with a new one.

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

Once its lifespan ends, it is essential to know the proper process for how to remove the FreeStyle Libre 2 sensor to avoid discomfort or skin irritation.

Tips for optimal use

To use your FreeStyle glucose sensor optimally and get the most out of it, we recommend following these tips:

• Avoid placing the sensor on areas with scars or irritated skin.

• Do not use creams or lotions before applying it.

• Wait at least 1 hour after applying it before doing water activities.

• Use an additional patch if you do intense sports or sweat a lot.

Advantages of using the FreeStyle sensor

The FreeStyle Libre has revolutionized diabetes management by offering a simpler and less invasive way to monitor glucose levels. However, while this is its greatest advantage, it is not the only one:

• Continuous monitoring without constant finger pricks.

• More accurate than traditional test strips.

• Customizable alarms for real-time alerts.

• Detailed glucose history in the app.

• Data sharing with family members and healthcare professionals.
