Garmin diabetes study shows 71 percent reversal rate with smartwatch AI

Smartwatches are quietly becoming serious medical devices. Garmin data shows AI-assisted tracking reversed diabetes in 71% of participants, compared to 2.4% in a control group, and Samsung's Galaxy Watch6 predicted fainting up to five minutes early with 84.6% accuracy across 132 patients. The fainting result is genuinely impressive until you see the other number: 64% specificity, meaning the watch cries wolf often enough that users will start ignoring it. A medical alert you stop trusting is just a notification.
