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.
Some insulin pumps include CGM. All CGMs need to be calibrated regularly with a blood glucose meter to be sure the readings are accurate.
