Glycemic Variability (GV), defined by a coefficient of variation (CV) >36%, is independently associated with an increased risk of hypoglycemia and diabetes-related complications, regardless of HbA1c levels.

Monitor your Glucose Coefficient of Variation (CV). If your CV is above 36%, your glucose is swinging too much, which increases complication risk. Work with your doctor to smooth out these swings using diet, exercise, or medication adjustments, even if your HbA1c looks okay.

Monnier et al. showed that a percentage coefficient of variation for glucose of 36% appears to be a suitable threshold to distinguish between stable and unstable glycemia in diabetes. It appears that beyond the 36% limit, the frequency of hypoglycemia is significantly increased, especially in insulin-treated subjects.
