Understanding Continuous Glucose Monitors (CGMs)

What is a CGM?

CGMs are advanced medical devices that continuously track glucose levels through a sensor placed under the skin. They offer a holistic view of glucose trends, facilitating better diabetes management.

Benefits of Using a CGM

CGMs enhance lifestyle flexibility and diabetes control by providing alerts for high and low glucose levels, reducing the need for traditional blood glucose testing, and offering insights into the impact of diet and exercise on glucose levels.
