ChatGPT for health information: How reliable is it?
ChatGPT is an artificial intelligence (AI) tool that uses advanced language technology to converse like a human. It aims to understand and learn from different topics, and users can train it to improve over time. Increasingly, people are turning to ChatGPT for health information and advice.
Around 1 in 6 adults and nearly a quarter of adults under the age of 30 use AI chatbots at least once per month when they need health advice and information.
In a 2023 survey of 607 people, around 78% said they would use ChatGPT to self-diagnose health issues. This is possibly because individuals seek quick explanations for their symptoms and may not want to wait until they can talk with a doctor.
This article discusses whether ChatGPT and other AI programs provide reliable health information. It outlines the possible benefits and drawbacks and gives some tips for using ChatGPT.
ChatGPT excels at defining medical terms and providing basic factual information. However, it is not medically trained and does not consider multiple factors and nuances when giving health information. This means it is a useful starting point for health information, but it cannot replace the insights of an experienced medical professional.
In a 2025 study, researchers asked four groups to translate frequently used medical terms into easy-to-understand language. These groups were general practitioners, resident doctors, specialist doctors, and ChatGPT.
ChatGPT was 100% accurate and outperformed all the other groups, suggesting it is useful for helping people understand complex medical terms.
However, a 2025 review of studies found that ChatGPT’s accuracy was variable when it came to more complex tasks. Across nine studies, researchers found the following:
Chat GPT’s accuracy ranged from 20% to 95%. The tool is helpful for providing general recommendations in certain situations, but its variability means people cannot rely on it for health information.
While many healthcare topics are nuanced and complex, the internet landscape is continuing to evolve in ways that provide shorter and more streamlined answers to user queries.
As of September 2025, AI-generated overviews often appear first when you search for a health topic. While some of these overviews are useful, they’re often inconsistent, inaccurate, and unreliable.
It is important to source health information from reputable, verified sources. Some examples include medical associations, government websites, and medical journals.
However, even these sources are not always up-to-date, consistent, or accurate, so it is best to connect with a healthcare professional if you have any questions about your healthcare.
ChatGPT is undoubtedly a useful starting point for health information and can help increase people’s understanding of medical facts and terms. However, it also carries some risks. Some of AI’s benefits and drawbacks are listed below.
ChatGPT and similar programs respond to the input a person gives them. The more detailed and specific the input, the more helpful the response is likely to be.
Ask clear and precise questions. Try to phrase the questions as simply as possible.
Provide extra details that might help the chatbot give an accurate answer.
ChatGPT often gives responses in formal language, which is difficult to understand. After asking a question, people can ask it to answer in simple language.
If a person wants a certain response from ChatGPT, they can ask for it.
To ensure ChatGPT formulates its answer from trustworthy sources, a person can ask it to use sources from leading institutions or
If a part of ChatGPT’s answer is unclear, ask follow-up questions or ask it to clarify certain points.
ChatGPT and other AI language tools offer instant answers to questions or instructions from users.
Many people turn to ChatGPT to get health information and advice. It is easy to access and available to anyone with internet access.
While AI can be helpful for initial questions about health, it is often not completely accurate and can sometimes be misleading. It does not have the same knowledge and experience as healthcare professionals. It may also cause unnecessary worry or give false reassurance, making people delay consulting a doctor when they need to.
If someone has concerning symptoms, they always need to speak with a healthcare professional. ChatGPT can be useful for helping them understand their health situation, but it should not replace professional medical advice.
