%20systems.png "Continuous Glucose Monitoring (CGM)")
several continuous glucose monitoring (CGM) systems are available on the market. Here are some of the most well-known CGM systems:
1. Dexcom G6:
Dexcom G6 is a widely used CGM system that provides continuous glucose monitoring without the need for routine fingerstick tests. It consists of a small sensor inserted under the skin, which measures glucose levels in interstitial fluid. The sensor communicates wirelessly with a receiver or smartphone app, providing real-time glucose data, trend arrows, and customizable alerts for high and low glucose levels.
2. FreeStyle Libre:
FreeStyle Libre is another popular CGM system that offers continuous glucose monitoring capabilities. It consists of a small sensor worn on the back of the upper arm and a reader device or smartphone app for scanning the sensor to obtain glucose readings. Unlike traditional CGM systems, FreeStyle Libre does not require calibration with fingerstick tests.
3. Medtronic Guardian Sensor 3:
The Guardian Sensor 3 is part of the Medtronic MiniMed 670G and 770G insulin pump systems. It is a CGM sensor that measures glucose levels in interstitial fluid and communicates wirelessly with the insulin pump to adjust insulin delivery automatically based on glucose trends.
4. Eversense:
Eversense is a long-term CGM system that consists of a sensor implanted under the skin in a minimally invasive procedure. The sensor communicates with a transmitter worn on the skin, which sends glucose data to a smartphone app for continuous monitoring.
5. Abbott FreeStyle Libre 2:
FreeStyle Libre 2 is an enhanced version of the original FreeStyle Libre system, offering optional real-time alarms for high and low glucose levels. It includes a sensor worn on the back of the upper arm and a reader device or smartphone app for scanning the sensor to obtain glucose readings.
These are just a few examples of CGM systems available on the market. Individuals with diabetes need to discuss their specific needs and preferences with their healthcare provider to determine which CGM system is best suited for them. Additionally, always check for the latest advancements and updates in CGM technology.
