<s>[INST] How does a continuous glucose monitor (CGM) work? [/INST] Continuous Glucose Monitors (CGMs) are small, wearable devices that continuously measure a person’s blood-glucose levels. They are used in place of traditional glucose meters and regular finger sticks.

A sensor just under the skin measures the tissue-glucose levels in real time; CGMs are mostly worn on the upper arm or abdomen. The levels are then relayed to a receiver, smartphone or watch, or insulin pump which displays the readings. Source: JDRF. Link: https://www.jdrf.org/t1d-resources/about/faq/. Field: Endocrine.
