Hello, Mamas! Today, we're discussing a topic that often causes a bit of confusion: the difference between Continuous Glucose Monitor (CGM) values and traditional finger stick blood sugar values.
If you're managing gestational diabetes, you might be using a CGM to keep a closer eye on your blood sugar levels throughout the day and night. While CGMs offer a fantastic way to monitor trends and patterns, you may have noticed that the values can sometimes differ from those obtained through finger stick blood sugar tests. Let's explore why this happens.
How CGMs Work
CGMs measure glucose levels in the interstitial fluid, which is the fluid between your cells.
Finger stick tests, on the other hand, measure glucose levels directly from your blood.
