How Can Patients Use AI to Better Understand Their Health?

Artificial intelligence can help patients understand medical information, interpret laboratory results and reports, prepare for doctor's appointments, compare treatment options, and think of questions they might not otherwise ask.

But AI can also be wrong. Think of it as a research assistant—not a replacement for your doctor.

Understand Medical Information

AI can translate medical language into ordinary English, and you can keep asking questions until the explanation makes sense.

For example:

“Explain insulin resistance in plain English.”

“What does this sentence from my MRI report mean?”

“Explain the difference between LDL cholesterol and ApoB.”

This conversational back-and-forth is one of AI's advantages over a traditional Internet search.

Understand Lab Results

You can enter or upload laboratory results and ask:

“What does this test measure?”

“What could cause this result to be high?”

“How does this result relate to my other results?”

“What questions should I ask my doctor?”

AI can help explain the numbers, but interpretation may depend on your medical history, medications, and other information.

Prepare for a Doctor's Appointment

Before an appointment, tell AI why you are going and ask:

“What information should I bring?”

“What are the five most important questions I should ask?”

Afterward, AI can also help explain something you didn't fully understand during the visit.

Understand a Diagnosis or Compare Treatments

If you receive a new diagnosis, AI can explain the condition and help you learn about treatment choices.

You might ask:

“What are the usual treatment options?”

“What are their benefits and risks?”

“Why might a doctor recommend one rather than another?”

One particularly useful question is:

“What information about me would a doctor need before making this decision?”

When You Have Several Medical Conditions

Medical decisions become more complicated when someone has several chronic conditions or takes multiple medications—common situations among older adults.

A treatment that helps one condition might worsen another. AI may not recognize these conflicts, particularly if it doesn't have a complete picture of your health.

One useful question is:

“How might this treatment affect someone with other medical conditions or medications?”

AI can help identify possible interactions and competing risks, but it may miss important ones. Your doctor or pharmacist should review potential medication interactions.

Challenge the Answer

Don't necessarily accept AI's first response. Ask:

“How strong is the evidence?”

“What evidence argues against this?”

“Is this generally accepted or controversial?”

“Give me links to the strongest sources.”

“What information would change your answer?”

These questions are particularly useful when exploring medical research, where preliminary findings, conflicting evidence, and well-established conclusions can easily become mixed together.

What If Different AI Systems Disagree?

Ask ChatGPT, Claude, or Gemini the same medical question, and you may get different answers.

Even respected medical organizations sometimes disagree about the best approaches to screening, prevention, and treatment.

These differences don't necessarily mean one answer is entirely wrong. Medical evidence can be incomplete, and recommendations may depend on individual circumstances.

If an AI answer seems surprising or important, consider checking it with another AI system—but don't assume that agreement between systems proves an answer is correct.

A particularly useful question is:

“Where do medical experts disagree about this, and why?”

AI for Exploring Other Perspectives

One of AI's most interesting possibilities is helping patients explore medical questions from a different perspective.

For example, if your doctor recommends a medication or procedure, you might ask:

“What alternatives should I discuss with my doctor?”
“What are the strongest arguments for and against this treatment?”
“Are there recent clinical studies that might affect this decision?”
“When would getting a second opinion from another physician be worthwhile?”

AI can help identify questions and alternatives that deserve consideration, but it cannot provide the equivalent of an independent medical evaluation.

Its greatest value may be helping patients participate more actively in decisions about their care.

Remember That AI Can Be Wrong

AI can misunderstand information, overlook an important detail, use outdated information, or confidently provide an incorrect answer.

For important medical questions, ask for sources, verify important claims, and discuss decisions about diagnosis or treatment with your doctor.

What About Medical Privacy?

When asking AI about personal health, it's tempting to upload medical records, laboratory reports, and detailed medical histories.

But privacy protections vary among AI services and account settings. Conversations may be stored, and some services may use them to improve their systems.

Before sharing sensitive information, review the service's privacy policies and settings. Consider removing your name, birth date, address, medical record numbers, and other identifying details when they aren't needed.

Paying for an AI subscription does not automatically guarantee that your medical information is confidential.

Bottom Line

AI gives patients something genuinely new: the ability to ask medical questions, request simpler explanations, challenge the answers, and continue asking follow-up questions.

Used thoughtfully, it can help us become better-informed patients who ask better questions and have better conversations with our doctors.
