A significant number of Americans, roughly one in eight, are turning to ChatGPT daily for medical guidance, a trend that experts caution could expose them to risky misinformation.

According to a fresh report from OpenAI, the creators behind ChatGPT, approximately 40 million Americans rely on the platform each day to inquire about symptoms or investigate treatment options.

Moreover, about 25% of Americans consult ChatGPT with their health-related questions on a weekly basis. Globally, healthcare concerns constitute one in every 20 messages sent to the service.

Each week, users pose around 2 million inquiries concerning health insurance, seeking clarity on comparing plans, managing claims, and understanding billing processes.

The report highlights that individuals in rural areas, where healthcare access is often limited, are particularly inclined to use ChatGPT, resulting in 600,000 messages emerging from these regions weekly.

And about seven in 10 health-related chat messages are sent outside of normal clinic hours, highlighting a need for health guidance in the evenings and on weekends. 

The report also found two in three American doctors have used ChatGPT in at least one case, while nearly half of nurses use AI weekly.  

Doctors who were not involved in the report told the Daily Mail that while ChatGPT has become more advanced and can help break down complex medical topics, it should not be a substitute for regular care.

Dr Anil Shah, a facial plastic surgeon at Shah Facial Plastics in Chicago, told the Daily Mail: ‘Used responsibly, AI has the potential to support patient education, improve visualization, and create more informed consultations. 

‘The problem is, we’re just not there yet.’

The findings come as OpenAI faces multiple lawsuits from people who claim they or their loved ones were harmed after using the technology. 

In California, 19-year-old college student Sam Nelson died of an overdose after asking ChatGPT for advice on taking drugs, his mother claims. 

SF Gate reported that, based on chat logs it reviewed, the service would first give a formal response insisting it could not help, but then if Nelson asked certain questions or phrased prompts a certain way, the tool was manipulated into providing answers. 

In another case, in April 2025, 16-year-old Adam Raine used ChatGPT to explore methods of ending his life, including what materials would be best for creating a noose. He later died by suicide.

Raine’s parents are involved in an ongoing lawsuit and seek ‘both damages for their son’s death and injunctive relief to prevent anything like this from ever happening again.’

The new report, published by OpenAI this week, found that three in five Americans view the healthcare system as ‘broken’ based on high costs, quality of care and a lack of nurses and other vital staff.

In a ranking of the share of healthcare messages from hospital deserts, or areas that are at least 30 minutes from a hospital, Wyoming had the most messages at four percent, followed by Oregon and Montana with three percent.  

The team cited a survey of 1,042 adults who used the AI survey tool Knit in December 2025. They found 55 percent of those adults use AI to check or explore their symptoms, while 52 percent use it to ask questions at any time of day.

Additionally, 48 percent turned to ChatGPT to understand medical terms or instructions, while 44 percent used it to learn about treatment options. 

The OpenAI team cited several case studies in the report. Ayrin Santoso, from San Francisco, told the company she used ChatGPT to help coordinate care for her mother in Indonesia after she suffered sudden vision loss. 

And Dr Margie Albers, a family physician in rural Montana, said she uses Oracle Clinical Assist, which relies on OpenAI models, to help take notes and save time on clerical work.  

Samantha Marxen, a licensed clinical alcohol and drug counselor and clinical director at Cliffside Recovery in New Jersey, told the Daily Mail: ‘One of the services that ChatGPT can provide is to make medical language clearer that is sometimes difficult to decipher or even overwhelming.’

Dr Melissa Perry, Dean of George Mason University’s College of Public Health who has studied AI usage in the medical setting, told the Daily Mail: ‘When used appropriately, AI can improve health literacy and support more informed conversations with clinicians.’

However, Marxen warned that the ‘main problem is misdiagnosis.’ 

‘The AI could give generic information that does not fit one’s particular case, thus leading the person to misjudging the severity of the symptom,’ she said. 

On the flip side, AI could make a user think they are experiencing ‘the worst-case scenario,’ Marxen said. 

Dr Katherine Eisenberg, senior medical director of Dyna AI, told the Daily Mail: ‘I do think ChatGPT opens up access to more types of medical information to patients, but people have to understand that ChatGPT is trying to serve every need for every user and is not specifically built or optimized for medicine. 

‘I would suggest treating it as a brainstorming tool that is not a definitive opinion.’

She added: ‘I actually don’t think people need to stop using ChatGPT for medical information entirely. I think we’re beyond that point, with the amount of use it’s getting today.’

Instead, she suggested double checking all information from a reliable source like an academic center and avoid putting in sensitive personal information. ‘Most importantly, patients should feel comfortable telling their care team where information came from, so it can be discussed openly and put in context,’ she said.
