Rising Concern: Google’s AI Overviews Accused of Giving Incorrect Medical Advice

Introduction

A growing number of investigations have found that Google’s generative AI search function, AI Overviews, has provided users with incorrect medical advice. These AI-generated summaries, designed to provide concise responses, appear at the top of search results. However, the tech behemoth removed some medical queries after the feature gave incorrect and potentially harmful advice in a number of health-related cases. Critics argue that this action does not adequately address more serious issues with the tool.

What Are Google AI Overviews?

When users ask questions, Google displays AI Overviews, which are summaries powered by generative AI, above traditional search results. These summaries, which combine data from multiple websites, aim to provide concise, easily understandable responses. Although the feature is marketed as a useful tool for quick information access, critics argue that it can oversimplify or misinterpret complex health issues, producing false results that are presented authoritatively.

Incidents of Incorrect Medical Advice

Misleading Dietary Guidance

One of the most well-known examples of Google AI Overviews’ incorrect medical advice was a question about dietary recommendations for patients with pancreatic cancer. Instead of increasing caloric intake, which is advised by medical professionals to help maintain weight, the AI overview recommended avoiding high-fat foods, which doctors warn could endanger patient health.

Liver Function Test Misinterpretation

Another serious error occurred with queries about liver blood test ranges. The AI Overviews provided lists of numerical values without proper context, neglecting critical variables such as age, sex, ethnicity, and specific test differences. Experts cautioned that this could lead individuals with liver disease to erroneously believe their results are normal and delay vital follow‑up care.

Ongoing Harmful Outputs

Investigations also exposed other problematic summaries on topics like cancer screening and mental health, which experts considered to be dangerous and inaccurate. Users may continue to see incorrect medical advice when search terms are phrased differently because equivalent AI overviews remain visible even after specific flagged cases are eliminated.

Actions Taken by Google

In response to these controversies, Google removed AI Overviews for some specific medical queries—such as “what is the normal range for liver blood tests” and “what is the normal range for liver function tests.” A company spokesperson explained that the firm does not comment on individual removals, but it works to make broad improvements and takes action under company policy when contextual errors are identified.

Google also stated that an internal team of clinicians reviews flagged content and that AI Overviews only appear when the company has high confidence in the quality of the response. Despite this, critics note that many problematic summaries remain active for variations of the same query terminology.

Expert Warnings and Public Risk

Medical professionals and digital safety advocates have sounded alarms over the risks of AI Overviews providing inaccurate medical advice. Health organizations such as the British Liver Trust emphasized that misleading AI health content could put lives at risk by giving false reassurances or encouraging harmful decisions.

Experts stress that health information requires nuanced interpretation and clinical context—something generative AI currently lacks. Simplified summaries that strip away essential variables like age or health status can create dangerous misunderstandings for users relying on these tools instead of consulting medical professionals.

Broader Implications for AI in Healthcare

The controversy surrounding Google AI Overviews’ incorrect medical advice highlights a larger challenge in applying AI to sensitive domains such as health. While companies like Google, OpenAI, and Anthropic are advancing AI technologies aimed at improving access to information and healthcare support, these incidents underscore the need for stronger safeguards, rigorous testing, and clearer boundaries when deploying AI in contexts where inaccuracies can have real‑world consequences.

Critics argue that offering AI‑generated medical summaries without robust verification or explicit disclaimers could erode public trust in digital tools and, in worst cases, contribute to health risks rather than alleviate them.

Conclusion

The example of Google’s AI Overviews providing inaccurate medical advice highlights the risks associated with depending on AI-generated answers for health-related information. Although Google has taken action to eliminate some risky summaries, experts argue that this only addresses isolated cases rather than the systemic problem of guaranteeing responsible and accurate AI outputs in healthcare contexts.

To avoid damaging misinformation and preserve public trust in the technology, it will be essential to prioritize accuracy, transparency, expert oversight, and user education as AI tools are further incorporated into routine information searches.
