Revolutionizing Diabetes Care with Advanced CGM Devices (original) (raw)

Advanced continuous glucose monitoring (CGM) devices offer real-time glucose readings, eliminating frequent finger stick testing to monitor blood sugar levels.

Continuous glucose monitoring (CGM) devices have transformed diabetes management by enabling continuous and accurate real-time tracking of blood glucose levels. These minimally invasive wearables eliminate the need for frequent fingerstick testing and play a vital role in effective chronic condition management for individuals with diabetes, prediabetes, or gestational diabetes.

By continuously monitoring glucose levels throughout the day and night, CGMs provide real-time data and trends to help people make informed treatment decisions.

In the United States, several brands of CGMs are available, each with varying levels of reliability and accuracy. The choice of the most suitable brand often depends on factors such as personal preference, ease of use, cost, and insurance coverage.

Personal CGM Devices

Personal CGM devices are wearable devices used by individuals with diabetes to monitor their blood glucose levels continuously. They consist of a sensor inserted under the skin. This transmitter sends data wirelessly to a receiver or smartphone app and provides real-time glucose readings, trend analyses, and customizable alarms. They help users make informed decisions about their diabetes management and improve glycemic control.

Personal FDA-approved CGM devices include Abbott’s FreeStyle Libre 2 and 3, Dexcom’s G6 and G7, Medtronic Diabetes’ Guardian Connect, and Senseonics’ Eversense E3.

Abbott FreeStyle Libre 2

The FreeStyle Libre 2 is a CGM system developed by Abbott that measures glucose levels in interstitial fluid (ISF), providing real-time data to the user. The sensor communicates wirelessly with a reader or compatible smartphone and features customizable high- and low-glucose alerts, helping users manage their diabetes more effectively.

Abbott FreeStyle Libre 3

Libre 3’s smaller size and matte finish offer enhanced comfort and minimized visibility. Unlike previous models, it holds data for longer periods, reducing the need for frequent scans. This innovation provides users instant access to glucose readings, offering more timely updates for improved diabetes management.

Dexcom G6

The Dexcom G6 is a CGM system that measures glucose levels in ISF. The sensor communicates wirelessly with a receiver or compatible smartphone, providing real-time glucose readings. It also features customizable high- and low-glucose alerts, trend arrows indicating the direction and rate of glucose change, and the ability to remotely share data with caregivers or healthcare providers. Unlike other CGM systems, Decom's sensors require an overpatch.

Dexcom G7

Dexcom G7 offers several improvements over previous models, including a smaller, more discreet design, a longer wear duration of up to 14 days, and a simplified sensor insertion process.

Medtronic Guardian Connect

Medtronic Diabetes developed the Guardian Connect CGM system that includes a small sensor, Guardian Sensor 3, that is inserted under the skin to measure glucose levels in ISF. The sensor communicates wirelessly with a compatible smartphone, allowing users to view their glucose readings in real time through a dedicated mobile app.

Guardian Connect gives users insights into their glucose trends, including rate of change and predictive alerts for high- and low-glucose levels. It also offers customizable alerts to notify users of potential high and low events.

Senseonics Eversense E3

The Eversense E3 CGM system, developed by Senseonics, consists of a small sensor implanted under the skin by a healthcare professional. The sensor continuously measures glucose levels in the ISF, providing real-time data to the user.

One of the distinguishing features of the Eversense E3 CGM is its long-term wearability, as the sensor can remain implanted for up to six months before needing replacement. The system also includes a wearable transmitter that communicates wirelessly with the sensor to relay glucose data to a compatible mobile app on the user's smartphone. Unlike other systems, this transmitter can be removed for short periods without wasting the sensor.

The Eversense E3 CGM also offers customizable alerts for high- and low-glucose levels, trend information to help users understand their glucose patterns, and the ability to share data with healthcare providers for remote monitoring and management.

Professional CGM Devices

Professional CGM devices are medical tools healthcare professionals use to monitor patients' glucose levels over an extended period. Unlike personal CGM devices worn and operated by individuals, professional CGM devices are typically placed and managed by medical professionals in clinical settings.

These devices are often used for short-term monitoring to gather comprehensive glucose data for diagnostic purposes, treatment optimization, and tracking glucose patterns.

Professional FDA-approved CGM devices include Abbott FreeStyle Libre Pro and Dexcom G6 Pro.

Abbott FreeStyle Libre Pro

The FreeStyle Libre Pro is a CGM sensor reader that stays in the clinic, where healthcare professionals can use it to view glucose data. One reader can scan multiple patients, minimizing waiting time and scheduling issues.

Dexcom G6 Pro

The Dexcom G6 Pro is an upgraded diabetes management tool used by medical practices, offering real-time patient data access and retrospective data review for healthcare providers.

CGM devices have significantly improved diabetes management, offering individuals continuous and accurate real-time tracking of blood glucose levels. With various available options, users can choose the device that best suits their needs, ensuring effective condition management. As technology advances, these devices hold promise in enhancing the quality of life for those with diabetes.
