There are many benefits of continuous glucose monitoring. Dr Daphne Su-Lyn Gardner, Consultant from the Department of Endocrinology, Singapore General Hospital, a member of the SingHealth group, shares a list.
Continuous glucose monitoring may either be retrospective for diagnostic purposes or it may be used in real-time.
Diagnostic continuous glucose monitoring systems are blinded to the individual who is wearing it. It is used by the healthcare professional to:
- Detect asymptomatic or nocturnal hypoglycaemia, and
- Aid in titration of medications, insulin doses or nutritional adjustments.
Real-time continuous glucose monitoring also contains alarms which can alert the user if the glucose level is rising or going below a pre-set threshold. This will allow the user to make changes to prevent or correct a high or low glucose level.
Most real-time continuous glucose monitoring requires once to twice daily blood glucose calibrations (involving fingerprick glucose tests) and each sensor lasts for up to 6 days.
"Real-time continuous glucose monitoring has been shown to improve overall glucose control in terms of improvements in HbA1c and reduction of the frequency of hypoglycaemia, particularly in those with type 1 diabetes," says

However, real-time continuous glucose monitoring needs to be used regularly for this improvement to be effected.
In addition, real-time continuous glucose monitoring may be combined with insulin pump therapy to allow for automated insulin suspension in response to, or prior to, a pre-set low glucose level. It may also be used in the future to control the high glucose levels by automatically controlling delivery of basal insulin.
