Continuous Glucose Monitor

Continuous glucose monitor

A continuous glucose monitor (CGM) has several parts. You wear one part-the sensor-against your skin. It has a tiny needle that stays under your skin and constantly reads your blood sugar level. It sends this information to a wireless receiver. The receiver can tell you if your blood sugar is going up or down-and how fast. And you can view the stored data to help you identify trends in your blood sugar level.
