What is the role of CGM?

Continuous Glucose Monitors (CGMs) are devices that provide real-time information about blood glucose levels, offering significant insights into metabolic health. Initially designed for individuals with Type 1 diabetes to manage insulin dosing, CGMs have since expanded to support people with Type 2 diabetes and even non-diabetics interested in monitoring their glucose responses to optimize their diet and health 1.

CGMs function by placing a filament under the skin that reads glucose levels from interstitial fluid, providing continuous monitoring without frequent blood sampling. This technology benefits those needing to adjust dietary and lifestyle choices based on immediate glucose readings. Moreover, understanding these glucose patterns can guide better nutrition and health decisions, adapting personal habits to maintain optimal glucose levels 2.

In practice, CGMs can also be used as behavioral tools. They help gamify the process of eating healthily, as the immediate feedback provided by the readings encourages individuals to make better nutritional choices. This addition of a "game element" has shown to enhance compliance with healthier eating practices, helping to avoid high-glucose foods that could spike blood sugar levels 2.
