Continuous Glucose Monitors

Continuous Glucose Monitors (CGMs) provide real-time, 24/7 data to help you understand how every meal, activity, and even stress affects your blood sugar. With this information, you can make informed choices about what to eat, when to exercise, and how to manage your well-being day to day. CGMs are small, wearable devices that track glucose levels through a tiny sensor placed just under the skin, eliminating the need for frequent finger pricks. Many CGMs offer smartphone integration, allowing you to easily monitor your trends, set alerts for highs and lows, and share your data with your care team. At The Functional Fork, I have curated in-depth reviews of the top prescription and over-the-counter CGMs available, highlighting the unique link for each. My goal is to help you find a device that fits seamlessly into your lifestyle, whether you’re newly diagnosed or an experienced user. Explore my resources to discover which CGM might be right for you, get tips for getting started, and learn how to get the most from your device for better diabetes management.
