Introduction – Comaprison Between Freestyle Libre 3 and Dexcom G7

For people with diabetes, it’s essential to keep track of their blood sugar levels to manage their health condition and avoid complications. Continuous Glucose Monitoring (CGM) devices have been a game-changer for many individuals, as they provide real-time information about glucose levels, allowing for better control and insight. Two of the most popular CGMs in the market are the Freestyle Libre 3 by Abbott and the Dexcom G7. However, deciding which is the right fit for you can be confusing. Therefore, we have created a guide that compares these two devices in detail to help you make an informed decision. For people with diabetes, having access to continuous, real-time data on glucose levels is critical for managing this chronic condition. Continuous glucose monitoring (CGM) devices have been life-changing for many, providing greater insight and control over blood sugar fluctuations. Two of the most popular CGMs on the market are the Freestyle Libre 3 by Abbott and the Dexcom G7. But how do you determine which one is best for you? This comprehensive guide compares all aspects of these two powerful diabetes management tools.

How Do CGMs Work?

The Freestyle Libre 3 and Dexcom G7 are devices that help people with diabetes keep track of their blood sugar levels. They use small sensors placed under the skin to measure glucose levels constantly. These readings are then sent to a receiver or mobile device, allowing users to see their levels in real-time and find patterns and trends. By having access to 24/7 data, people with diabetes can make better choices about what they eat, how active they are, and how much medication they need. These devices also alert when blood sugar levels get too high or low, which can help prevent dangerous situations.

Similarities Between the Devices

 While some key differences exist, the Freestyle Libre 3 and Dexcom G7 share some core features and capabilities. Both devices:

Use minimally invasive sensors worn under the skin to measure interstitial fluid glucose levels.

Provide real-time glucose data that can be accessed on a reader, receiver, or compatible mobile device.

Have accompanying mobile apps for monitoring data, trends, and alerts

Allow users to share data with caregivers and healthcare providers.

Are highly accurate systems that meet the latest standards for CGMs

Help diabetes patients better manage their blood sugar fluctuations and A1C.

Key Differences Between the Freestyle Libre 3 and Dexcom G7

Although Freestyle Libre 3 and Dexcom G7 are advanced Continuous Glucose Monitoring (CGM) systems, they differ significantly in their features and capabilities. Expert users would be interested in exploring and understanding these differences to identify the best-suited option for their specific needs.

Sensor & Insertion

The Freestyle Libre 3 has a small, thin sensor inserted using a one-piece applicator on the back of the upper arm. It lasts 14 days before needing replacement.

The Dexcom G7 has a wider sensor inserted via an auto-applicator on the arm's belly, upper buttocks, or back. It lasts ten days before replacement.

Scanning & Monitoring

The Freestyle Libre 3 has a built-in scanner for direct sensor scans without entering codes. This allows for on-demand glucose checks whenever needed.
The Dexcom G7 requires users to check glucose levels using a dedicated receiver or mobile device connected to the sensor. Scans are not on-demand.

Alerts & Alarms

CGMs offer customizable alerts and alarms for detecting high and low glucose levels.

The Dexcom G7 also has an Urgent Low Soon alert that predicts hypoglycemia before it hits.

Display Devices

The Freestyle Libre 3 utilizes a dedicated handheld reader or the LibreLink mobile app.
With more display options, the Dexcom G7 sends data to a receiver or mobile device or integrates with smartwatches.

Data Sharing & Remote Monitoring

With the Freestyle LibreView app, you can easily share your glucose data with up to 20 people you trust. This can help you keep your loved ones informed about your health and progress so they can support you better.

The Dexcom G7 system enables remote real-time monitoring of a user's glucose levels by providing alerts to followers. This system ensures the user can be monitored even from afar, enabling timely interventions and better diabetes management.

Cost Comparison

The Freestyle Libre 3 is a device that monitors blood sugar levels for people with diabetes. The sensors, which need to be replaced every 14 days, cost around $75-100. In addition, the device that reads the information from the sensors costs about $70.
The Dexcom G7 sensors cost between $350-400 for a 10-day supply. Additionally, the receiver needed to use the sensor costs around $200.
The cost of a system can be influenced by insurance coverage and the rates that have been negotiated.

Ease of Use

The Freestyle Libre 3 system is a user-friendly device that requires no calibration. It's designed to be simple and easy to use, making it an excellent option for anyone looking for a hassle-free way to manage their health.

The Dexcom G7 is a device that helps people keep track of their blood sugar levels. It requires more effort than other devices, as its sensors must be calibrated twice daily using a fingerstick reading.

Discreet Design

The tiny Libre 3 sensor can be worn discreetly on the back of your arm, even under your clothes.

The Dexcom G7 sensor is bigger than previous versions but can be placed in less noticeable spots if needed.

Final Thought

To sum up, the Freestyle Libre 3 and Dexcom G7 offer reliable and uninterrupted data crucial for effective diabetes management. When deciding between these two advanced CGM systems, several factors should be considered, such as supply costs, insurance coverage, ease of use, scanning convenience, sensor wear time, data sharing requirements, and discretion. By analyzing your specific needs and preferences, you can determine which of these systems is the most suitable for your lifestyle and glucose control objectives.
