Estimated Glucose Disposal Rate (eGDR)
Estimated glucose disposal rate (Williams KV, et al. Diabetes Care 2000) = 21.158 - (0.09 x waist cm) - (3.407 x hypertension) - (0.551 x HbA1c %); lower = greater insulin resistance.

Example
- Waist circumference
- 100 cm
- Hypertension
- Yes
- HbA1c
- 8 %
Result: Estimated glucose disposal rate 4.34 mg/kg/min — lower = greater insulin resistance.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- mg/kg/min
- 21.158 - 0.09·waist(cm) - 3.407·hypertension - 0.551·HbA1c. Lower = greater insulin resistance, higher = better sensitivity. A surrogate, not a diagnosis.
What you enter
- Waist circumference
- Hypertension (treated or BP >= 140/90)
- HbA1c
