In this episode of the Glucose Never Lies podcast, hosts John Pemberton and Louise discuss the intricacies of diabetes management, focusing on continuous glucose monitoring (CGM) systems. They explore various CGM features, including calibration, alarms, and connectivity with automated insulin delivery (AID) systems. The conversation emphasizes the importance of understanding individual needs when selecting a CGM, as well as the role of technology in enhancing diabetes care. The hosts also provide insights into the latest advancements in CGM technology and offer resources for further education.

Takeaways

• Continuous glucose monitors (CGMs) have evolved to include factory calibration.
• Optional calibration can be beneficial but requires accurate blood glucose meters.
• Alarm fatigue can hinder effective diabetes management.
• The Freestyle Libre is noted for its small size and long wear time.
• Dexcom products offer extensive connectivity with AID systems.
• Understanding individual needs is crucial when selecting a CGM.
• AI-driven forecasts in CGMs can enhance decision-making for users.
• Education and support are vital for effective diabetes management.
• Resources like the DSM Forum provide valuable information for diabetes care.
