You may need to start a continuous glucose monitoring (CGM) device. If you're about to start one, here's what you should know.
A CGM device consists of a small, wearable transmitter and sensor that continuously measures glucose levels in the fluid under the skin, as well as an app or display reader device used to view real-time data.
CGM devices require a prescription from a physician and need to be calibrated with finger stick glucose measurements. To ensure the accuracy of data, regular maintenance and calibration are imperative, and the device should be changed every three days.
