ChatGPT Now Links to User Health Data

OpenAI is launching Health in ChatGPT for US users, enabling connections to Apple Health and supported medical records so ChatGPT can reference health information during conversations. According to OpenAI, connected medical records, Apple Health data, and related conversations are not used for model training or advertising.

The feature is now available to logged-in US users aged 18 and older on web and iOS across Free, Go, Plus, and Pro plans, accessible from the ChatGPT sidebar.

Users may still ask health questions without connecting any data. With user permission, ChatGPT can access connected information such as medications, lab results, recent visits, sleep, and activity.

It can compare new results with prior tests, summarize changes since the last appointment, or relate sleep, activity, and workouts to a routine. OpenAI states that over 300 million people use ChatGPT for health-related questions each week, often with relevant information spread across patient portals, records, apps, and wearables.

The company notes that connected medical records and Apple Health information, and conversations that use them, are excluded from foundation model training and ad targeting regardless of the user’s model-training setting. Conversations that do not use this data follow the user’s standard model-training settings, adjustable in Settings, then Data Controls.

By default, ChatGPT requests permission before using connected records to personalize responses. Users can approve each request or choose to always allow access, which disables prompts, by adjusting Settings under Plugins and Health.

OpenAI collaborates with hundreds of physicians to develop health scenarios and assessment rubrics for accuracy, safety, communication, context awareness, completeness, and escalation. They report that all GPT-5.6 models outperformed GPT-5.5 on HealthBench Professional, its evaluation for challenging health tasks.

OpenAI states that Health is built with layered privacy and security safeguards. All ChatGPT conversations are encrypted at rest and in transit, and information connected in Health receives additional encryption.

Users can disconnect Health information at any time in Health under Accounts. OpenAI states that data from a disconnected source is deleted from its systems within 30 days, though information already in conversation history remains until those conversations are deleted.

Memories are not created directly from connected medical records or Apple Health information. Users can use Temporary Chat or disable memory in Settings under Memory. Users can connect Apple Health, supported medical records from US hospital systems, One Medical, or Function Health to get responses based on their own data.

Users can open Health from the sidebar or More menu in ChatGPT, select “Get started,” and follow the guided connection process. Once synced, users can ask questions anywhere in ChatGPT and add @Health to a message to explicitly request health context.

However, connected information may not always be complete or current. OpenAI advises users to verify important details with the original source and consult a healthcare provider for medical decisions.

OpenAI emphasizes that ChatGPT may still make mistakes and does not replace qualified medical professionals, encouraging users to verify important information with a healthcare provider.

It will be important to see how the feature impacts the way people interact with their health information and healthcare providers as it becomes more widely available.
