Continuous glucose monitoring (CGM) through Medtronic has evolved into a fully integrated ecosystem that treats blood sugar management as a semi closed-loop process rather than just data collection. By feeding a continuous stream directly into an automated insulin delivery (AID) system like the MiniMed 780G, these sensors enable SmartGuard technology to make proactive dosing adjustments every five minutes. This integration is vital because it shifts the focus from manual corrections to automated Time in Range (TIR) optimization, specifically targeting hidden challenges like the dawn phenomenon and nighttime glycemic variability. For the experienced user, this creates an externalized endocrine loop where the sensor and pump work in tandem to preemptively head off highs and lows, significantly reducing the daily cognitive burden of metabolic management.
