Continuous Glucose Monitor
CGM stands for Continuous Glucose Monitoring. It is a method of monitoring blood glucose levels in people with diabetes. CGM involves wearing a small device that continuously measures glucose levels in the interstitial fluid (fluid between cells) beneath the skin. The device then transmits the glucose readings to a receiver or smartphone app, which can provide real-time data on glucose levels, trends, and alerts for high or low levels.
CGM is a useful tool for people with diabetes as it allows for better management of blood glucose levels and helps prevent episodes of hypoglycemia (low blood glucose levels) and hyperglycemia (high blood glucose levels). CGM is especially helpful for people who have difficulty managing their blood glucose levels through traditional self-monitoring methods or who have hypoglycemia unawareness.
Freestyle Libre is a brand of continuous glucose monitoring (CGM) system used by people with diabetes to monitor their blood sugar levels. The system consists of a small sensor that is attached to the skin and a reader or a smartphone app that is used to scan the sensor and display the glucose readings.
When the sensor is scanned with the reader or the smartphone app, it displays the current glucose reading, as well as a trend arrow indicating whether the glucose levels are rising, falling, or staying steady. The system also allows users to set alarms to alert them when their glucose levels are too high or too low.
The Freestyle Libre system can be used by people with type 1 diabetes, type 2 diabetes, and gestational diabetes, and has been shown to improve glucose control and reduce the risk of hypoglycemia (low blood sugar) in people with diabetes. However, it is important to note that CGM systems, including the Freestyle Libre, are not a replacement for regular blood glucose monitoring and should be used in conjunction with regular medical care and diabetes management.
