Continuous Glucose Monitors are compact medical devices that measure glucose levels in the interstitial fluid - the fluid that controounds cells just beneath the skin. Unlike traditional blood glucose meters that require a fingstick blood tampe for each reading, CGMs automatically transgrad glucosa levels every few minutes, 24 hour a day. This continous stream of data provides a dynamic picture of glucoste trendes, include rapiccispikes all meals, overnight lows, and how athal activitectes affectes lectes lectes lectis.

Te ability to see glukose variability - not just average levels - has shifted thee focus from HbA1c alone to timetime- in- range as a moractionable metric.

How Do CGM Work?

A CGM system consiss of three main considents: a sensor, a transmitter, and a receiver or smartphone app. Te sensor is a thin, flexible filament inserted jutt under the skin - usually on the abdomen or upper arm.
