The I HART CGM study compared time spent low in people type 1 diabetes and IAH treated with rtCGM to those treated with isCGM and found that rtCGM, but not isCGM, reduced hypoglycemia exposure.2,3.
further diminishes hypoglycemia exposure, signicantly re-. ducing hypoglycemia relative to a CGM system without the.The CGM monitors allow for precise control of BG variations and accurate planning of physical activity by adjusting the insulin and carbohydrate consumption dose.
The Position Statement. CGM Accuracy and Lag. Types and Duration of Exercise.To reduce the risk of late or nocturnal hypoglycemia, CGM low alerts can be raised to at least 80 mg/dL for the night, and added carbohydrate consumed at that level or below. Recommendations for Children.
Participants used insulin pump therapy with real-time CGM at home for two overnight periods and one day-and-night period with closed-loop control. There was no supervision provided during the study periods; telephone support was available to participants for technical issues.

Learn what your blood sugar readings mean. Make immediate treatment decisions based on your Dexcom app and real-time CGM data.
Real-time CGM can improve awareness and reduce the burden of problematic hypoglycemia in patients with long-standing T1D, but with only modest improvement in the endogenous glucose production response that is required to prevent or correct low blood glucose.
Avoid common CGM mistakes for better diabetes management. Learn how sensor placement, skin preparation, calibration, and data interpretation impact glucose monitoring accuracy.

However, accuracy is criticalan unreliable CGM can lead to incorrect insulin dosing and health risks. This post compares the accuracy of three leading CGM sensors: Dexcom G7, FreeStyle Libre 3, and Medtronic Simplera, based on a recent study.
