Think it\u2019s just a fitness-tracking accessory? One man asked ChatGPT to analyze 10 years of his Apple Watch data, and what it found out freaked him out enough to call his doctor. <\/p>\n

After handing over a decade of Apple Watch stats, a journalist asked ChatGPT Health to judge his heart.<\/p>\n

The chatbot reviewed 29 million steps and 6 million heartbeat measurements extremely quickly and delivered a brutal verdict. <\/p>\n

What followed was enough to send him running to his real-life human doctor for reassurance \u2013 but the medical practitioner\u2019s response was not what you might expect.<\/p>\n

ChatGPT analyzed 10 years of this man\u2019s Apple Watch data<\/p>\n

Did you know that there was a doctor living in all your gadgets<\/a> this whole time?<\/p>\n

ChatGPT<\/a> Health says it can help users understand long-term health patterns by analyzing fitness tracker data and medical records, and most people have Apple Watches or iPhones, which track their medical data.<\/p>\n

Curious about what a decade of wearing an Apple Watch<\/a> might reveal, a Washington Post journalist joined a short wait list and gave the AI access to everything stored in his Apple Health app.<\/p>\n

He asked the AI assistant<\/a> to grade his cardiac health, and to his shock, the answer came back as an F.<\/p>\n

Alarmed, he immediately went for a run and then sent the full report to his actual doctor.<\/p>\n

The response from his physician could not have been more different.<\/p>\n

According to his doctor, he was at such low risk for a heart attack that his insurance would likely not even cover additional testing to prove the AI wrong.<\/p>\n

He also shared the results with cardiologist Eric Topol from the Scripps Research Institute, and Topol dismissed the analysis outright, calling it baseless.<\/p>\n

He added that the system was not ready to provide medical guidance at all, accurate or otherwise.<\/p>\n

He decided he had to call his doctor<\/p>\n

As the Washington Post journalist<\/a> kept using ChatGPT Health, the problems stacked up.<\/p>\n

When he asked for heart health and longevity scores, the grades shifted from an F to a D after he connected his medical records, then fluctuated wildly between different conversations with the ChatBot.<\/p>\n

Much of the negative scoring focused on Apple Watch VO2<\/a> max estimates and heart rate variability, metrics that experts say can be fuzzy and misleading when taken at face value.<\/p>\n

Even Apple describes VO2 max on the Watch as an estimate rather than a clinical measurement.<\/p>\n

\"Man<\/a>Geoffrey A. Fowler\/ChatGPT<\/p>\n

The chatbot also treated inconsistent data as meaningful signals, including changes that appeared whenever the user upgraded to a new Apple Watch.<\/p>\n

Over time, ChatGPT forgot basic details like age and gender, and sometimes ignored recent blood test results it had access to.<\/p>\n

While ChatGPT Health was useful for plotting data and spotting broad activity trends, its confident but unstable conclusions raised serious concerns as to whether people are blindly believing it.<\/p>\n

\"\"<\/a>Geoffrey A. Fowler\/ChatGPT<\/p>\n

In the end, the experience served as a reminder that while AI health tools sound impressive, they are no substitute for an actual doctor who understands the full picture and has years of proper training.<\/p>\n
