CGM unveils what no meter can. While meters give a number for a single point in time, CGM provides dynamic glucose information by showing where glucose is, where it’s going, and how fast it’s getting there.
Dexcom’s CGM consists of 3 parts1:
1. Small Sensor that measures glucose levels just underneath the skin.
2. Transmitter that is fastened on top of the sensor and sends data wirelessly to the receiver.
3. Receiver that displays your glucose trends in vivid colors so you can easily see when it’s high, low or within range.
