What is involved in CGM?
Continuous glucose monitoring sensors (CGMS) involves wearing a small glucose sensor inserted in the interstitial fluid just under the skin.
The sensor will provide a reading every 5 minutes and is normally worn for a 6-7 day period depending on the brand of sensor. Once complete, the data is uploaded and plotted onto graphs, enabling identification of glucose patterns.
Your doctor or diabetes specialist may recommend continuous blood glucose monitor if you are experiencing fluctuations or concerning trends in your blood glucose levels, especially overnight.
CGMS can be offered to people using insulin pumps as well as to those on multiple daily injections, including people with type 1 or type 2 diabetes.
CGMS can be a very valuable problem solving tool for both you and your diabetes health team.
Different CGMS available
There are two types of CGMS:
- Real-time monitoring which can be seen live on a receiver
- Retrospective monitoring where we look at the data at the end of the sensor period and reflect on the effects of food, medications and exercise.
There are systems available that can work on their own and those that talk to some insulin pumps.
You and your diabetes team will decide on the best type of CGMS for your needs.
What does the investigation cost?
There is a small cost for the sensor and we will loan the transmitter and /or receiver for the trial period. If you would like to purchase a CGMS then we can also assist with that process.
