Glucose
Estimated Average Glucose (eAG)
What This Marker Tells Us
Converts your hemoglobin A1C into average blood glucose over the past 2-3 months, translating the percentage into the mg/dL units you see on glucose meters.
Why It Matters
Relates A1C to daily glucose experiences. While A1C represents overall glycemic control, eAG helps visualize what average glucose actually means for tissue damage, energy levels, and metabolic health. Chronically elevated glucose glycates proteins throughout your body, damaging blood vessels, nerves, kidneys, eyes, and brain. eAG contextualizes A1C in familiar units, clarifying diabetes risk and metabolic status.
How to Interpret Your Trends
Low eAG (below 100 mg/dL) indicates tight glucose control with minimal glycation damage. Typical values (100-125 mg/dL) suggest normal glucose metabolism but room for optimization. Elevated eAG (126-154 mg/dL) indicates prediabetes with accelerated glycation damage. High values (above 154 mg/dL) signal diabetes with significant ongoing tissue damage. Even within normal ranges, lower values associate with better health outcomes.
What Influences This Marker
Dietary carbohydrate intake, meal timing, and glycemic index dramatically affect average glucose. Insulin resistance, obesity, physical inactivity, stress, and poor sleep elevate glucose chronically. Exercise, particularly after meals, lowers glucose. Low-carb or Mediterranean diets, time-restricted eating, weight loss, and improved sleep lower eAG. Medications, certain hormones, and illness temporarily raise glucose.
How Your Team Uses It
Your coach uses eAG to translate A1C into actionable glucose targets, making glycemic control goals tangible. It guides continuous glucose monitoring interpretation and meal timing strategies. eAG improvements track dietary and lifestyle intervention effectiveness for metabolic optimization. The familiar units facilitate communication about glucose control progress.
