A continuous glucose monitor (CGM) is a device that you attach to your body. It shows your blood sugar (glucose) level at least every 5 minutes, day and night. If your blood sugar is too low and you don't notice it, a CGM can alert you in time to get treatment. Your doctor may also recommend using a CGM to help you stay in your target blood sugar range more consistently.
A CGM has several parts:
Some insulin pumps include CGM. In this case, the insulin pump is also the receiver.
The readings from the CGM can help you decide what to eat and how to exercise. And they can help you know how much medicine to take. You can note on the receiver when you do these things. That way you can see how those activities affect your blood sugar throughout the day and night. All this detailed information gives you and your doctor a better idea of what your treatment needs are.
