what is gmi mean

GMI stands for Glucose Management Indicator. It is a metric used to estimate your average blood glucose levels over the past 2-3 months, similar to the A1C test. GMI is calculated using data from continuous glucose monitoring (CGM) devices and provides an approximation of what your A1C might be based on your glucose readings.

How is GMI calculated?

GMI is derived from the average glucose levels recorded by a CGM device. The formula used is:

GMI (%) = 3.31 + 0.02392 × (average glucose in mg/dL)

Key Points:

• GMI vs. A1C: While GMI is based on CGM data, A1C measures the percentage of glycated hemoglobin in your blood. They may not always match due to individual variations in red blood cell lifespan and other factors.
• Usefulness: GMI helps people with diabetes understand their glucose trends and make informed decisions about their diabetes management.

If you use a CGM device, your GMI can be a helpful tool to track your glucose control over time.
