Continuous Glucose Monitoring (CGM) is a modern diabetes management technology that tracks glucose levels throughout the day and night using a small sensor placed under the skin. Unlike occasional finger-prick testing, CGM provides ongoing glucose information, helping patients and healthcare professionals understand glucose patterns and trends.
How Does CGM Work?
A CGM sensor measures glucose in the fluid beneath the skin and sends readings to a compatible receiver or smartphone. Depending on the device, users may receive real-time readings, trend information, and alerts for high or low glucose levels. CGM data can help healthcare professionals make informed decisions about diabetes treatment, diet, physical activity, and insulin management.
Who Can Benefit from CGM?
CGM may be recommended for people with type 1 diabetes, type 2 diabetes, and others who require closer glucose monitoring, particularly those using insulin or treatments that may cause hypoglycemia. The appropriate device and monitoring approach should be selected according to individual needs and medical advice.
