Continuous Glucose Monitoring

Dexcom

Dexcom, headquartered in San Diego, California, is the global leader in real-time continuous glucose monitoring (CGM) systems for people with diabetes, with the Dexcom G7 sensor-transmitter now approved for use without fingerstick calibration. The company's CGM devices generate high-resolution glycaemic data — a reading every five minutes — that has transformed both clinical diabetes management and academic research into metabolic physiology. Dexcom collaborates with endocrinology departments and diabetes technology centres at Stanford, Yale, and international academic medical centres on closed-loop insulin delivery (artificial pancreas) systems, precision nutrition studies, and sports physiology research using CGM in athlete cohorts. Its open API and integration with commercial closed-loop systems (Control-IQ, MiniMed) has enabled a new generation of academic research on automated insulin delivery algorithms.
