What is Continuous Glucose Monitoring (CGM)?
CGM is a glucose management tool that measures glucose levels 24 hours a day using a sensor inserted just under the skin. The wearable sends glucose readings to a compatible device such as phone† or an optional receiver.‡ It provides you with real-time glucose readings and can also alert you when your levels are too high or drop too low.
