CONTINUOUS GLUCOSE MONITORING (CGM)
A CGM works by reading the glucose level of the interstitial fluid (fluid around the cells) every 5 minutes. This effectively gives continuous information as to the current glucose level in your blood and trends. This works by:
A thin sensor being placed under the skin by you, the person with diabetes. It is changed every 6 - 14 days depending on the device.
The sensor has a transmitter attached and this sends a signal from the sensor to a receiver.
The receiver may be a specific receiver, a telephone or an insulin pump. The receiver shows the level of glucose continuously.
Anyone with diabetes can use a CGM however since April 2017 people with diabetes under the age of 21, if they meet set criteria, are able to have the cost of CGM covered under a government scheme.
