The difference between CGMS and BGMS

The difference between CGMS and BGMS

Traditional blood glucose monitoring systems (BGMS) require you to stop and check your blood sugar at set times, with a finger prick. In contrast, a Continuous Glucose Monitoring System (CGMS) checks your glucose levels around the clock automatically. With a CGMS, your readings are sent straight to an app on your phone in real time, so you always know where your glucose levels are heading without needing to do anything.

Why CGM and BGM Readings Can Be Different

Blood glucose monitors (BGMs) measure glucose directly from your blood, while Continuous Glucose Monitoring Systems (CGMS) measure it from the fluid that surrounds your body’s cells (called interstitial fluid).

Because it takes a little time; usually 5 to 15 minutes for glucose to move from your blood into this fluid, the readings may not always match.

When your glucose levels are stable, both readings are usually very similar. But during rapid changes (like after eating, exercise, or insulin), the numbers can differ slightly.

That’s why CGMs are especially helpful as they track patterns and trends, and send alerts if your levels go too high or too low, giving you time to act and make managing your diabetes easier.
