Glucose Variability

Meaning

Glucose variability is a clinical metric that quantifies the magnitude and frequency of fluctuations in blood glucose levels over a defined period, independent of the average glucose concentration. High variability is characterized by frequent and wide swings between hyperglycemic peaks and hypoglycemic troughs. In hormonal health, excessive glucose variability is a potent driver of oxidative stress, endothelial dysfunction, and impaired insulin signaling, contributing significantly to metabolic dysfunction and hormonal imbalance.
