Continuous Glucose Monitoring (CGM) is like having a personal blood sugar guardian by your side 24/7. It’s a tiny sensor that you wear on your body, usually on your skin, which continuously checks your blood sugar levels. This sensor sends real-time data to a device or app, allowing you to see how your blood sugar changes throughout the day.

With this information, you and your doctor can better understand how your body responds to food, exercise, and medication. It’s especially helpful for people with diabetes as it helps them make more informed decisions about their diet and insulin or medication doses.
