Apple Watch Glucose Monitoring Gets Major Breakthrough
Key Points:
- Apple Watch currently supports blood sugar monitoring by displaying data from existing continuous glucose monitors (CGMs), but does not measure glucose levels directly on the device itself.
- The Dexcom G7 CGM now connects directly to the Apple Watch without needing a nearby iPhone, enabling greater independence for users during activities like swimming or remote hiking, and allows sharing data with multiple devices simultaneously.
- Apple is developing a non-invasive glucose monitoring technology using optical absorption spectroscopy to measure glucose through the skin without needles or external sensors, though this innovation remains several years from commercial release.
- The project faces significant engineering challenges, including miniaturizing the technology to fit a wrist-worn device while maintaining medical-grade accuracy and battery efficiency, with extensive testing conducted to support future FDA
