Consumers are increasingly turning to artificial intelligence chatbots for health information, a new report from Rock Health says.
Thirty-two percent of respondents in the 2025 Consumer Adoption of Digital Health Survey reported using AI chatbots to find health information, up from 16% in 2024. Researchers at the digital health venture fund polled 8,000 U.S. Census-matched adults in December 2025 on their attitudes and behaviors toward digital health tools and care.
The survey was conducted before AI platforms introduced their own healthcare chatbot offerings, such as Microsoft’s Copilot Health and OpenAI’s ChatGPT Health.
“For many, AI has quickly become a routine part of how they manage their health,” the report said. “Sixty-four percent of AI users engage with it for health questions weekly or more often.”
ChatGPT and Gemini topped the most-used AI chatbots for health information, with 23% and 15% of respondents using the platforms, respectively. AI users most frequently search for treatment options based on a diagnosis and for pre-diagnosis based on symptoms.
Researchers note AI is “becoming a single engagement point for the entire healthcare experience,” with users also searching for questions to ask at appointments, managing mental health needs and looking for specific providers and clinics.
Following AI chatbot queries, users reported taking a range of actions, including searching for more information (42%), consulting a provider (40%), discussing with family or friends (35%), trying a new health behavior, advising someone else, changing or making a healthcare appointment and adjusting medication.
There are concerns surrounding using such tools to find healthcare information, the report notes, despite its increasing prevalence—including with clinical accuracy and declining use of “I am not a doctor” disclaimers.
Researchers also analyzed demographic metrics for AI users. Forty-five percent of Gen Z adults and 48% of Millennials reported using AI chatbots to find health information, while usage is lower among older generations.
Racial and ethnic minorities were also more likely to use chatbots for healthcare, but researchers found only slightly higher AI use among men than women.
As AI use increases among patients, researchers said the role of a physician “may shift” from a primary source of information to more of a guiding presence.
“The next chapter will reveal whether the system can keep these forces in balance—so that always-on availability does not outrun standards of care, and clinical rigor, privacy, and safety do not fall behind consumer momentum,” the report said.
