Continuous Glucose Monitors (CGMs) have transformed diabetes management, offering real-time glucose data via smartphone integration. Leading devices like the Dexcom G6 excel in connectivity, while the Stelo by Dexcom offers unprecedented over-the-counter accessibility. Options such as the Abbott Freestyle Libre 3 Plus provide a balance of features and affordability, and the Eversense 365 offers a long-term solution with a year-long sensor. For advanced data analysis, the Guardian Connect System provides predictive alerts. Selecting the right CGM depends on factors like scan frequency, connectivity, sensor longevity, and insurance coverage. Consulting healthcare providers is recommended for critical health decisions.
