Overview
Dexcom designs, develops, and commercializes continuous glucose monitoring (CGM) systems that measure interstitial glucose levels every five minutes and transmit readings wirelessly to a smartphone or compatible insulin pump. The Dexcom G7 — the company's seventh-generation sensor — is a fully disposable, all-in-one system that attaches directly to the skin without a separate transmitter, features a 30-minute warm-up time, and is approved for insulin dosing decisions in people with Type 1 and Type 2 diabetes. The Stelo biosensor extends CGM to people without diabetes for general wellness glucose tracking. People living with diabetes, their families, and the endocrinologists and primary care physicians managing their care rely on Dexcom CGM to replace painful fingerstick testing with continuous, contextual glucose data. Integration with automated insulin delivery systems including Tandem Diabetes Care's Control-IQ and Omnipod 5 enables closed-loop "artificial pancreas" functionality that automatically adjusts insulin delivery based on real-time glucose trends. Dexcom serves over 2 million active users globally and generates more than $3.6 billion in annual revenue, establishing it as the global CGM market leader by revenue. The company's Clarity software platform enables population-level glucose pattern analysis for clinicians managing large diabetes patient panels. Direct API integrations with Apple Health, Google Health, Garmin, and major EHR systems make Dexcom data actionable within broader care workflows.
