Empower Your Health with Continuous Glucose Monitoring

Modern CGMs are highly accurate, typically within 9-12% of blood glucose meter readings. They measure glucose in interstitial fluid, which has a 5-15 minute lag compared to blood glucose. Most CGMs no longer require fingerstick calibrations.

The initial insertion may cause brief discomfort, similar to a small pinch. Once inserted, most users don't feel the sensor. The tiny filament sits just under the skin and is designed for comfortable extended wear.

Yes! Most CGMs are water-resistant and can be worn while showering, bathing, or swimming. However, check your specific device's depth and duration limits. Additional adhesive patches can help keep sensors secure during water activities.

Many insurance plans, including Medicare, cover CGMs for people with diabetes who use insulin. Coverage has expanded significantly in recent years. We recommend contacting your insurance provider or using manufacturer support programs to verify coverage.

Trend arrows show the direction and rate of glucose change. A single arrow indicates slow change (1-2 mg/dL per minute), while double arrows show rapid change (more than 2 mg/dL per minute). This helps you anticipate and prevent highs or lows.

Yes! Many CGMs integrate with insulin pumps in automated insulin delivery (AID) systems. These 'closed-loop' systems automatically adjust insulin delivery based on CGM readings, significantly improving glucose control.
