Continuous glucose monitoring is also known as CGM. This system automatically tracks glucose levels, throughout the day and night. You can see your glucose levels anytime at a glance, on your smartphone, smartwatch or monitor without any other checks. You can also review how your glucose changes over a few hours or days to see trends. Seeing glucose levels in real-time can help you make more informed decisions throughout the day about how to balance your food, physical activity, and medicines.
A CGM works through a tiny sensor inserted under the skin of a person living with type 1 diabetes. It’s usually worn on your tummy or arm. The sensor measures your interstitial glucose levels, which is the glucose found in the fluid between the cells. The sensor tracks glucose every few minutes. A transmitter wirelessly sends the information to a monitor or compatible mobile device. A finger prick check may still be needed, especially if the person with type 1 feels different to what the sensor is reading.
The monitor may be part of an insulin pump or a separate device, which you might carry in a pocket or purse.
