Google is taking a significant step in personalized health by enabling Fitbit’s AI health coach to access users' medical records. This move positions Google alongside industry rivals like Amazon, OpenAI, and Microsoft, all of whom are banking on users' willingness to share highly sensitive personal data in exchange for more tailored health guidance. While Google asserts this data will empower the AI coach to offer superior advice, it explicitly states that the technology is not designed to diagnose, treat, or monitor medical conditions.
Beginning next month, a preview will allow US Fitbit users to link their medical records directly to the Fitbit application. This integration will combine essential medical data, such as lab results, prescribed medications, and visit histories, with existing wearable data. According to Florence Thng, Google's health intelligence product management director, this comprehensive data set will enable Fitbit’s AI-powered health coach to deliver "safer, more relevant and more personalized" recommendations, as detailed in a recent blog post.
Thng provided an illustrative example: "Instead of getting a generic answer about cholesterol, you can ask, 'How can I improve my cholesterol?' The coach can then summarize your cholesterol labs, highlighting notable values and trends, and provide personalized wellness information based on your medical history and wearable data." This demonstrates the AI's capability to move beyond general information to offer actionable, individualized insights.
Furthermore, Thng indicated that in the coming months, users will gain the ability to "securely share" their medical records and AI-generated summaries with family members or healthcare providers through a simple link or QR code. Emphasizing user control and privacy, Thng reaffirmed that, consistent with other health data within Fitbit, medical records will not be utilized for advertising purposes. Users will retain full authority over how their data is used, shared, or deleted.
Despite these advancements, a small disclaimer within Google's blog post clarifies that the demonstrations are purely "illustrative." It explicitly states that "Fitbit is not intended to use your medical records to diagnose, treat, cure, prevent, or monitor any disease or condition," strongly advising users to consult a professional "before making changes concerning your health."
Beyond medical record integration, Fitbit’s sleep tracking functionality is also receiving a substantial upgrade, which Google hails as "our most significant update yet." The company announced that sleep tracking will achieve 15 percent greater accuracy, improving its ability to differentiate between actual sleep and periods of wakefulness or attempted sleep. This enhanced tracking will begin rolling out in preview "over the next few days," with an improved sleep score feature to follow in the coming weeks.
This strategic move to integrate medical records with Fitbit’s AI health coach underscores the growing recognition of health and wellness as a primary consumer application for artificial intelligence. It aligns with a broader trend where tech, wellness, and fitness companies are leveraging AI to expand their service offerings and provide more intricate insights into users' lives. For instance, wearable tech innovators like smart ring manufacturer Oura and fitness tracker Whoop already employ dedicated chatbots for personalized advice. Similarly, AI developers Anthropic and OpenAI actively encourage users to share data with their respective chatbots, Claude and ChatGPT, for health discussions—a path Google, whose Gemini AI powers Fitbit’s coach, has not yet publicly pursued for its own general chatbot.
Companies operating in this space, despite consistently asserting that their products are not designed to diagnose or treat conditions, are navigating a potentially precarious landscape with regulatory bodies such as the FDA. They face rigorous scrutiny regarding the handling of sensitive user data. Notably, many AI-driven health products have not yet been introduced in regions with stringent privacy legislation, like Europe. Experts caution users to exercise significant care when sharing personal health information, a warning that is particularly pertinent for reproductive data in the United States.
