Given the lack of well-established blood glucose targets outside of type 1 diabetes, Dr. Canelo reviews commonly used ranges for individuals without diabetes, those with prediabetes, and pregnant patients with type 1 or 2 diabetes. He explains how to interpret CGM data, including the time in tight range, coefficient of variation, and the importance of focusing on overall trends rather than isolated glucose spikes. They also discuss the potential drawbacks associated with CGM use, including anxiety and eating-disorder risks. Practical considerations include sensor inaccuracies, false lows readings, and optimizing alarm settings. Dr. Canelo emphasizes the importance of having patients log meals and other events while wearing the sensor and scheduling follow-up after the initial 15-day wear period to ensure accurate interpretation and effective counseling. Finally, they compare OTC and prescription CGM options, including costs, clinician access to patient data, and insertion tips.
