This might be the best way to get medical advice from ChatGPT - and it's free to use

OpenAI announced ChatGPT Health, a dedicated health and wellness experience in ChatGPT that can securely integrate user medical records and data from apps like Apple Health, MyFitnessPal, and Peloton to help with tasks such as preparing for appointments, planning questions, and receiving personalized diet and workout guidance. OpenAI states the feature is not for diagnosis or treatment, adds layered security protections with encryption and isolation, and ensures Health conversations aren’t used for foundation model training or mixed with other chats. Access is rolling out via a waitlist, with broader availability planned across web and iOS.
