What is Continuous Glucose Monitoring?

CGM is a sophisticated medical device that continuously tracks your blood glucose levels 24 hours a day, seven days a week. Unlike traditional finger-prick tests that provide only a single snapshot, CGM systems deliver real-time glucose data every few minutes, creating a comprehensive picture of your metabolic patterns.

The technology utilizes a tiny, minimally invasive sensor placed just beneath the skin that measures glucose levels in the interstitial fluid — the fluid surrounding your body's cells. This sensor wirelessly transmits data to your smartphone or receiver, providing continuous monitoring without the discomfort of frequent blood draws.

How CGM Technology Works

Unlike traditional finger-prick tests that provide only a single snapshot, CGM systems deliver real-time glucose data every few minutes, creating a comprehensive picture of your metabolic patterns.

Advanced Sensor

A tiny sensor is painlessly inserted under the skin (arm, abdomen, or other fatty area) and stays active for up to 15 days.

Real-Time Data

Every 1–5 minutes, your glucose is measured and sent via Bluetooth to your phone or receiver — up to 288 readings per day.

Comprehensive Insights

CGM uncovers overnight and post-meal trends you'd miss with finger sticks, revealing patterns linked to insulin resistance.

Evidence-based personalization

At Prewelle, our providers use CGM data to develop highly personalized intervention strategies based on your unique glucose patterns. Continuous monitoring enables remote patient support and timely adjustments to treatment plans.

Prediabetes Management

CGM-guided nutrition improves diet quality, glucose control, and sleep, boosting whole-grain and plant-protein intake.

Metabolic Optimization

With only 12% of adults metabolically healthy, CGM helps the rest make data-driven lifestyle choices to prevent diabetes.

Personalized Strategies

Providers use CGM patterns to tailor diet, exercise, and lifestyle plans to your unique metabolic profile.

Key Benefits

Early Detection

Spot hidden glucose spikes — post-meal highs, overnight rises, and variability linked to insulin resistance — so you can act before issues emerge.

Personalized Nutrition

See real-time responses to foods and fine-tune meals, timing, portions, and macros for stable glucose levels.

Optimized Activity

Use glucose data to tailor workouts and choose activities that support balanced metabolism.

CGM uses a small sensor under the skin to measure glucose continuously, providing 24/7 trends and alerts. Finger sticks give single-point readings only.

No. The sensor is applied with a spring-loaded applicator in seconds and causes only minor, brief discomfort.

Sensors remain active for up to 15 days.

It records glucose every 1–5 minutes, for up to 288 readings per day.

You can monitor readings on a compatible smartphone app or a dedicated receiver via Bluetooth.

Our CGM system is approved for non-adjunctive use, meaning finger sticks are only needed for calibration or when symptoms don't match readings.

Yes. You can set personalized thresholds and receive real-time alarms for glucose levels outside your target range.

CGM is ideal for individuals with prediabetes or diabetes, as well as health-conscious adults seeking to optimize nutrition, exercise, sleep, and stress management.

Schedule an initial consultation, get sensor placement, connect your device, and review your data with a clinician to create a tailored action plan.
