Three in Ten Adults Use Social Media and AI for Health Information and Advice, Despite Lack of Confidence in Information Accuracy

Nearly three in ten U.S. adults now use social media and artificial intelligence tools for health-related advice, according to data from the KFF Health Tracking Poll. While social media remains a primary hub for peer-based support, the use of AI chatbots for medical information has nearly doubled over the past two years, signaling a shift in how the public seeks health guidance outside of traditional clinical settings.

Who is using AI and social media for health?

Demographic patterns reveal distinct audiences for these digital health tools. Younger adults, specifically those aged 18 to 29, are the most frequent users of both social media and AI for health information. According to KFF, while Hispanic adults show high adoption rates across both platforms, social media usage is more prevalent among lower-income groups. In contrast, AI tool usage shows less variation across income levels, though it is notably popular among adults aged 30 to 49.

Why patients turn to digital sources

Many users prioritize immediacy and community when seeking health information online. Data indicates that over one-third of social media users turn to these platforms to connect with others who share similar health conditions. For many, this digital interaction fills a gap in the traditional healthcare system.

Approximately 17% of social media users and a similar share of AI users report that a primary reason for using these tools is a lack of a regular healthcare provider or the inability to afford professional medical costs. This trend is particularly pronounced among uninsured individuals and LGBT adults, who may face additional barriers to accessing conventional care, such as systemic stigma or financial constraints.

Confidence versus clinical verification

Although users express moderate confidence in their ability to distinguish true from false information—with roughly 61% reporting confidence in social media health advice and 56% in AI-generated information—actual verification rates remain low.

According to findings from the KFF poll, a majority of users rarely or never consult a medical professional to verify the information they find online. Only about 36% of social media health users follow up with a doctor "every time" or "most of the time." Even fewer users verify their findings through reputable government health agencies, such as the Centers for Disease Control and Prevention (CDC), with only 21% doing so consistently.

Risks of digital health guidance

The reliance on non-clinical sources creates a significant potential for misinformation. While social media provides a sense of community, it lacks the diagnostic rigor of a clinical examination. Medical professionals emphasize that online advice cannot replace a physical assessment, laboratory testing, or a personalized treatment plan.

The growth in AI usage presents a unique challenge, as these systems can produce "hallucinations" or provide outdated medical guidance that may not account for a patient’s specific health history. Experts recommend that patients use these tools only as a starting point for conversation with their primary care physician rather than as a substitute for professional medical judgment.

Summary of Health Information Sources

As digital health adoption continues to rise, the gap between online convenience and clinical verification remains a critical concern for public health. Patients are encouraged to bring any health information gathered from social media or AI tools to their next scheduled appointment to ensure it aligns with evidence-based medical standards.
