What is Real Time Continuous Glucose Monitoring (rt-CGM)?
Real Time Continuous Glucose Monitoring (rt-CGM) is a way to track glucose levels throughout the day and night in real time. A small rt-CGM sensor takes glucose measurements at regular intervals, up to 24 hours a day. A transmitter then sends the data to a display device via Bluetooth to show a current glucose value. The system also displays arrows that show the direction and speed glucose is changing.
Continuous data can help you proactively manage glucose highs and lows. Real time alerts can give added insight into what different factors affect your glucose levels in the moment. Learn how meals, exercise and insulin cause your glucose levels to change through the day.
