What is CGM?

Continuous Glucose Monitoring (CGM) offers a revolutionary way to track blood sugar levels continuously, providing invaluable insights for managing diabetes. Unlike traditional glucose meters, CGM devices offer real-time monitoring. CGM utilizes a small sensor placed just under the skin, which provides real-time glucose readings at frequent intervals throughout the day and night.

The sensor readings are then transmitted over to a compact receiver (a device typically smaller than a smartphone), allowing users to monitor their glucose trends conveniently via a graphical interface and alerting them when levels become too high or too low.

The Benefits of CGM

There are numerous benefits of transitioning to a CGM system. It can facilitate better diabetes management and enable users to promptly detect fluctuations in their glucose levels. Moreover, a CGM device can also allow users extra time to take corrective actions. By frequently tracking data, a CGM system can help simplify life for users and give them a more comprehensive insight into how lifestyle factors can influence their diabetes management.

While CGM is commonly associated with Type 1 diabetes, the benefits of CGM can extend to individuals with Type 2 diabetes and prediabetes, particularly those individuals using insulin. Recent research even suggests that CGM can support adherence to exercise plans among individuals with Type 2 diabetes and prediabetes, contributing to improved health outcomes.

Over a short period of time, the technology behind CGM has undergone significant advancements, showcasing improvements in accuracy, reliability, and user-friendliness.


Choosing the Right CGM

When choosing the most suitable system for your needs, it is essential to understand the distinctions between the two primary types of CGMs: real-time and intermittently scanned. It is recommended to thoroughly explore both options and consult with your physician, healthcare provider and/or diabetes educator for personalized guidance. They can offer valuable insights into selecting the right CGM system for you, assist with transitioning to CGM use, and provide training on interpreting and utilizing your glucose data effectively to manage your condition and attain your blood sugar targets.
