If you’re living with diabetes, managing your blood sugar is a daily priority. That used to mean multiple finger pricks every day—but thanks to Continuous Glucose Monitoring (CGM) systems, tracking glucose levels is easier, less painful, and more informative than ever.

But with more options available, you might be wondering:

Which CGM is best for me?

At Piedmont Medical Solutions, we supply two of the most trusted CGM brands on the market—Abbott FreeStyle Libre and Dexcom—and we’re here to help you decide which one fits your life and your health goals.

What Is a CGM, and How Does It Work?

A Continuous Glucose Monitor (CGM) is a small, wearable device that tracks your glucose levels throughout the day and night. Instead of fingersticks, it uses a tiny sensor inserted just under the skin to measure glucose levels in the interstitial fluid.

Most CGMs Include:

  • A sensor (applied to the back of your arm or abdomen)
  • A transmitter (built-in or separate)
  • A reader or smartphone app to display your glucose readings

These systems let you monitor your glucose in real time, track trends, set custom alerts for highs and lows, and share your data with your care team—all without the constant need for test strips.

Who Should Use a CGM?

CGMs can be life-changing for many people with diabetes, especially those who:

  • Use multiple daily insulin injections
  • Have frequent highs or lows
  • Experience hypoglycemia unawareness
  • Want better insights into how food, activity, and medications affect their blood sugar
  • Are tired of frequent fingersticks

If that sounds like you—or someone you care for—a CGM might be the tool you’ve been looking for.

How to Choose the Best CGM for You

Every person with diabetes is different, and the “best” CGM is the one that fits your lifestyle, needs, and comfort level. Here are a few questions to help guide your choice:

Ask Yourself:

  • Do I want real-time alerts sent automatically, or am I okay with scanning?
    • Go Dexcom for automatic updates; Libre for scan-based tracking.
  • Do I use or plan to use an insulin pump?
    • Dexcom may offer better integration options.
  • Do I want something simple and easy to use?
    • Libre systems are often praised for their simplicity.
  • Do I prefer a smaller, more discreet sensor?
    • Libre 3 Plus and Dexcom G7 are both excellent for comfort and low profile.
  • Will my insurance cover the cost?
    • Both systems are often covered by Medicare and most private insurers—and Piedmont Medical Solutions can help verify your coverage.
