What Are Continuous Glucose Monitors and How Do They Work?

Continuous glucose monitors are wearable devices that track blood glucose levels in real-time through a tiny sensor inserted just beneath the skin. Unlike traditional finger-prick tests that provide single moment-in-time readings, CGMs deliver continuous data streams showing how your body responds to food, exercise, stress, and sleep.

The fundamental technology behind CGM systems involves:

• Miniaturized sensors that measure glucose in interstitial fluid
• Transmitters that wirelessly send data to smartphones or receivers
• Algorithms that interpret glucose patterns and trends
• Mobile applications that display actionable insights

Modern CGM systems like Levels, Nutrisense, and Signos use Abbott’s Libre Sense or Dexcom G6 sensors, which are FDA-cleared for non-adjunctive use, meaning they’re accurate enough to make treatment decisions without confirmatory fingerstick tests.

Key physiological markers tracked by these systems include:

• Glucose variability – How much your blood sugar fluctuates
• Postprandial responses – How foods affect your glucose after eating
• Fasting glucose – Your baseline glucose levels upon waking
• Time in range – Percentage of time spent in optimal glucose zones

Why Should Healthy People Monitor Their Glucose Levels?

The assumption that only diabetics need glucose monitoring represents one of the biggest misconceptions in preventive health. Even people with “normal” HbA1c levels can experience significant glucose spikes that contribute to inflammation, energy crashes, and long-term health risks.

Emerging research demonstrates that glucose dysregulation in non-diabetic individuals correlates with:
✓ Increased risk of cardiovascular disease
✓ Accelerated aging processes
✓ Cognitive decline and brain fog
✓ Weight management difficulties
✓ Hormonal imbalances
✓ Reduced athletic performance

Optimal glucose control benefits everyone through:

• Sustained energy levels without midday crashes
• Improved body composition and easier weight management
• Enhanced mental clarity and cognitive performance
• Reduced inflammation throughout the body
• Better sleep quality and recovery
• Long-term metabolic resilience
