Continuous glucose monitoring

What is continuous glucose monitoring?

Continuous Glucose Monitoring (CGM) is a means of measuring glucose levels continuously in order to gain insight into patterns and trends in glucose levels throughout the day and night.

A Continuous Glucose Monitoring System sensor is worn separately to the pump, inserted under the skin, and measures the level of glucose in the interstitial fluid (fluid in the tissue). The sensor is disposable and changed according to manufacturer recommendations.

The cost of CGM including consumables (sensors) is around $5,000 per year.

How does it help me manage my diabetes?

CGM can sound an alarm if the glucose level is changing rapidly. A “hypo” or the trend towards a “hypo” can trigger an alarm alerting the user or family/carer to treat immediately. "Hypo" refers to hypoglycaemia, when the blood glucose level has dropped too low. Alerts can prevent a hypo before it happens and is particularly useful overnight when parents and children are in separate rooms.

What continuous glucose monitoring systems are available to me?

During the 2016 Federal Election, the Government committed to subsidise continuous glucose monitoring (CGM) technology to assist children and young adults under 21 years of age who face extra challenges managing their type 1 diabetes.

Diabetes Australia strongly advocated for CGM funding and has been working constructively with the Federal Government and the Department of Health to ensure the initiative is implemented successfully. The Diabetes Australia funding submission can be read here.

The Australian Government is now providing access to subsidised continuous glucose monitoring (CGM) products through the National Diabetes Services Scheme (NDSS). Visit the NDSS website to find out more.

There are several continuous glucose monitoring systems available in Australia for people living who require insulin to manage their diabetes. These include:
