Continuous Glucose Monitoring (CGM) systems have revolutionized diabetes management, providing real-time glucose data to help individuals make informed decisions about their health. With various brands available, each offering unique features and technologies, it can be challenging to determine which CGM system is the best fit. This article explores the leading CGM brands, comparing their features, technologies, and user experiences.
What is Continuous Glucose Monitoring?
Continuous Glucose Monitoring involves the use of a small sensor placed under the skin that measures glucose levels in the interstitial fluid. This data is transmitted to a receiver or smartphone app, allowing users to monitor their glucose levels continuously throughout the day and night.
Key Features of CGM Systems
- Real-time glucose monitoring
- Alerts for high and low glucose levels
- Data sharing capabilities
- Integration with insulin pumps
- Mobile app compatibility
