Man's AI diet advice linked to hospital stay, exposing a blind spot

A 60-year-old man asked ChatGPT for ways to reduce chloride in his diet and, following its dietary advice, replaced table salt with sodium bromide. He later developed hallucinations and paranoia and required hospital treatment. The chatbot conversation could not be retrieved, so doctors were unable to determine exactly what advice he had received. The case was detailed in a paper by researchers from Binghamton University, Stanford University, Texas A&M University and Indiana University, which argues that the lack of transparency around AI-generated health advice makes such cases hard to investigate. OpenAI said ChatGPT is not a doctor and should never be used as a substitute for medical care, diagnosis, or treatment. The authors also recommend creating systems that allow AI-generated health guidance to be flagged, reported and examined.

Notes on gaps
The F1 link is an inference from the statement that the conversation could not be retrieved; the sources do not name a logging control. The remediation is the researchers' advice, not a change made by a party. The Gallup survey figure concerns other people and is not used as incident data.
