How to make AI a good partner for your health

Imagine this: It is 10 p.m., and you have a headache that has not gone away. You wonder whether it is from stress, lack of sleep, or something more serious. You open an AI chatbot and ask, “Should I be worried about my headache?” Within seconds, you get an answer. But how much should you trust it?

AI has rapidly become part of our everyday lives, including the way we look for health information. Nearly 8 in 10 U.S. adults say they are likely to go online for answers about health symptoms or conditions. In a 2025 international web-based survey, about 1 in 5 participants reported using AI chatbots such as ChatGPT for health information. [1–3]

AI is fast, convenient, and often free. But AI-generated health information is not always reliable or accurate. The key is knowing how to use it—and when not to rely on it.

How Can I Use AI for My Health? How You Ask AI Matters.

• Generally Safe Questions

AI can be useful for learning about health and simplifying complicated medical information.

For example:

• “Explain this medical term or my doctor’s instructions in simple words.” (Simplify information)
• “What is hypertension?”
• “Explain diabetes in simple terms.”

You can also ask for general ideas about healthy habits:

• “What are some ways to reduce stress?”
• “How can I improve my sleep habits?”
• “How can I become more physically active?”
• “What are some ways to eat a healthier diet?”

Think of AI as a tool to learn and generate ideas, rather than to make medical decisions for you.

• Questions to Ask with Caution

People often ask AI about new symptoms, like the headache in our opening example. You can ask these questions, but the answer should not replace a healthcare professional’s clinical judgment.

The quality of an AI answer depends on the information you provide, and the way you phrase a question can influence the response.

Instead of simply asking: 

• “Do I have a migraine?”

you might ask:

• “I have these symptoms [description]. What are some common possible causes, and what additional information would be useful to discuss with my doctor?” (Explore possibilities)
• “Help me organize when my headaches started, how often they occur, and what makes them better or worse.” (Prepare for your visit)

In this way, AI can help you organize your symptoms and prepare for a conversation with your healthcare professional, rather than trying to diagnose you.

• Questions You Should Not Rely on AI For

Based on the current limitations of AI, you should not rely on a chatbot alone to diagnose an illness or decide how a medical condition should be treated.

AI can be wrong even when it sounds confident. It can also provide incomplete or biased information.

Avoid relying on AI alone for questions such as:

• “Is this the right treatment plan for me?”
• “Should I take this medication?”
• “Is this the correct chemotherapy regimen?”

Treatment decisions depend on many factors, including your medical history, medications, test results, physical examination, personal preferences, and a healthcare professional’s clinical judgment.

Instead, use AI to help you understand and prepare:

• “What are the common treatments for [diagnosis], and what are the general benefits, risks, and side effects?” (Know your options)
• “What questions should I ask my doctor about this situation?” (Prepare for your visit)

The Bottom Line

Think of AI as a research assistant, not your healthcare professional. AI can help explain medical information, suggest healthy habits, organize symptoms, and prepare you for a medical visit. But it can also provide incorrect information, sometimes called “hallucinations.”

Most importantly, do not rely on AI for medical emergencies, diagnosis, or treatment decisions, and do not consider it a replacement for your physician. Use AI to learn, organize, and prepare. Use healthcare professionals to diagnose, treat, and make important medical decisions.

If you have serious or sudden symptoms or think you may be experiencing a medical emergency, seek immediate medical care or call 911 in the United States.
