What is a continuous glucose monitor (CGM)?

Continuous glucose monitoring (CGM) is a tool that that has changed how diabetes is managed for people with type 1 diabetes.

Whether you/your child uses shots or a pump, you can use a CGM system. A small sensor is inserted under the skin and sends a signal via a transmitter to a receiver (either a separate receiver or a smartphone or an insulin pump). It tells you what the glucose level is every few minutes and gives trends to indicate if blood glucose levels are falling, rising, or staying the same.
