In January 2026, OpenAI launched ChatGPT Health, a dedicated healthcare feature that represents one of the most significant entries into personalized health AI. The service allows users to securely connect their medical records and wellness apps—including Apple Health, MyFitnessPal, Function, and Weight Watchers—to receive personalized health guidance grounded in their actual health data. The launch addresses a massive unmet need: over 230 million people globally ask ChatGPT health and wellness questions weekly, making health one of the platform's most common use cases.
The service, developed over two years with input from 260+ physicians across 60 countries, uses b.well's FHIR-based infrastructure to connect with 2.2 million healthcare providers and 320 health plans in the United States. This connectivity enables ChatGPT Health to provide personalized responses based on users' actual medical records, test results, and health patterns, rather than generic health information. However, OpenAI explicitly states that ChatGPT Health is designed to "support—not replace—medical care" and is not intended for diagnosis or treatment.
The launch represents a fundamental shift in how AI can be applied to healthcare. Rather than providing generic health information, ChatGPT Health creates a personalized health assistant that understands your medical history, tracks your wellness data, and helps you prepare for doctor appointments, understand test results, and manage diet and fitness routines. This personalization, combined with OpenAI's conversational AI capabilities, could transform how people interact with their health information.
However, the launch also raises significant questions about privacy, accuracy, and the role of AI in healthcare. Health data is among the most sensitive personal information, and integrating it with AI systems requires extraordinary security measures. Additionally, AI systems are prone to hallucinations and inaccuracies, which could be dangerous in medical contexts. These concerns are particularly relevant given that a teenager died in 2025 after receiving drug advice from ChatGPT, highlighting the risks of relying on AI for medical guidance.
The Scale of Health Questions: 230 Million Weekly Users
The launch of ChatGPT Health addresses a demand that was already massive. According to OpenAI's announcement, over 230 million people globally ask ChatGPT health and wellness questions weekly, making health one of the platform's most common use cases. This scale demonstrates both the need for better health information access and the trust people place in AI systems for health guidance.
The types of questions people ask range from understanding symptoms and medications to interpreting test results and managing chronic conditions. Many of these questions reflect gaps in healthcare access: people may not have easy access to healthcare providers, may struggle to understand medical information, or may need help between appointments. ChatGPT Health aims to address these gaps by providing personalized, accessible health guidance.
However, the scale of health questions also highlights the responsibility OpenAI has taken on. When 230 million people are asking health questions, the accuracy and safety of responses become critical. A single incorrect answer could have serious consequences, which is why OpenAI has been careful to position ChatGPT Health as a support tool rather than a replacement for medical care.
The development process reflects this responsibility. OpenAI worked with 260+ physicians across 60 countries over two years to develop ChatGPT Health, ensuring that the service is grounded in medical expertise and best practices. This extensive consultation process distinguishes ChatGPT Health from generic AI health tools and demonstrates OpenAI's commitment to creating a responsible healthcare AI product.
The b.well Partnership: Connecting 2.2 Million Healthcare Providers
One of the most critical aspects of ChatGPT Health is its ability to connect with users' actual medical records. This connectivity is enabled through a partnership with b.well, a health data connectivity infrastructure provider that operates a network covering 2.2 million healthcare providers and 320 health plans, labs, and other sources in the United States.
According to b.well's announcement, the partnership uses FHIR-based APIs (Fast Healthcare Interoperability Resources) and trusted healthcare exchange frameworks to securely connect medical records. This infrastructure enables ChatGPT Health to access users' longitudinal health information—their complete medical history across providers and over time—rather than just isolated pieces of information.
The b.well SDK for Health AI transforms connected health data into clean, aggregated, AI-optimized inputs for large language models. This transformation is crucial because medical records are often fragmented, inconsistent, and difficult for AI systems to process. The SDK standardizes and structures this data, making it usable for ChatGPT Health's personalized responses.
The partnership also addresses one of healthcare's persistent challenges: data fragmentation. Most people receive care from multiple providers, and their health information is scattered across different systems. ChatGPT Health, through b.well, can aggregate this information into a unified view, enabling more comprehensive and accurate health guidance.
However, the partnership also raises questions about data security and privacy. Connecting medical records to an AI system requires extraordinary security measures, and users must trust that their sensitive health information will be protected. The b.well partnership provides the technical infrastructure, but OpenAI must ensure that its own systems maintain the highest security standards.
Wellness App Integration: Apple Health, MyFitnessPal, and Function
Beyond medical records, ChatGPT Health integrates with wellness apps including Apple Health, MyFitnessPal, Function, Weight Watchers, and Peloton. This integration enables ChatGPT Health to provide a comprehensive view of users' health and wellness, combining clinical data with lifestyle information.
According to MyFitnessPal's announcement, the integration enables personalized recipe recommendations, macro and protein guidance, daily calorie targets, and weight-management support tailored to fitness goals like weight loss, maintenance, or muscle gain. This personalization is based on users' actual dietary patterns and fitness data, enabling more relevant and actionable guidance.

The Function integration provides access to additional wellness data, while Weight Watchers and Peloton integrations enable ChatGPT Health to understand users' fitness routines and goals. These integrations demonstrate how ChatGPT Health aims to be a comprehensive health assistant, not just a medical information tool.
However, the integration of wellness apps also raises privacy questions. While medical records are subject to strict privacy regulations like HIPAA, wellness app data may have different privacy protections. Users must understand what data is being shared and how it's being used, particularly as OpenAI explores advertising as a business model.
Privacy and Security: Isolated, Encrypted, Never Used for Training
One of the most critical aspects of ChatGPT Health is its privacy and security architecture. According to OpenAI's privacy policy, ChatGPT Health operates as a separate, isolated space within ChatGPT with purpose-built encryption and isolation. Health conversations, files, and memories are not used to train OpenAI's foundation models, and health data is kept compartmentalized and not shared with other ChatGPT interactions.
This isolation is crucial because health data is among the most sensitive personal information. Users must trust that their medical records, test results, and health conversations will remain private and secure. The separate space architecture ensures that health data doesn't leak into regular ChatGPT conversations or training data.
The encryption and isolation measures address one of the primary concerns about AI health tools: data security. Health data breaches can have serious consequences, and integrating medical records with AI systems creates new attack surfaces. OpenAI's isolation architecture minimizes these risks by keeping health data separate from the rest of the system.
However, privacy experts have raised concerns. According to Healthcare Info Security, experts emphasize the need for "airtight" safeguards around sensitive health data, particularly as OpenAI explores advertising as a business model. The question of whether health data could be used for advertising or other commercial purposes remains a concern, even with current privacy protections.
Additionally, OpenAI has not confirmed HIPAA compliance, which is a critical requirement for handling protected health information in the United States. While ChatGPT Health may not be a covered entity under HIPAA, the lack of explicit HIPAA compliance raises questions about the legal framework governing health data protection.
The Development Process: 260+ Physicians Across 60 Countries
