Using AI For Health Questions Safely

AI chatbots can help you understand medical words, test results and questions to ask your doctor, but they can be wrong and can't examine you. In an emergency, call 911 (USA) or 999 (UK) first. Use AI to prepare, then check anything important with your doctor, nurse or pharmacist.

In An Emergency, Call First

USA: Emergency

If you think someone is having a stroke, heart attack or other emergency, call 911 now. Don’t stop to ask an AI. For mental health crisis support, call or text 988.

UK: Emergency

For a life-threatening emergency, such as stroke or heart attack signs, call 999 now. Don’t stop to ask an AI. For urgent help that isn’t an emergency, call NHS 111 or use 111.nhs.uk.

What Is AI Good For With Health Questions?

  • Explaining jargon. "What does 'benign' mean on my letter?" or "What is an HbA1c test?"
  • Preparing for appointments. "Help me write a list of questions to ask my doctor about my new blood pressure tablets."
  • Understanding a leaflet in plainer words, or in larger type you can read out loud.
  • Everyday wellbeing ideas, like gentle exercise or healthy recipes, as long as they fit any advice from your own doctor.

What Is AI Not Good For?

  • Diagnosing you. It can't examine you, see your full records or run tests, and it can sound sure while being wrong.
  • Changing medicines or doses. Always ask your doctor or pharmacist.
  • Emergencies. Every minute counts. Call for help first.
  • Replacing a second opinion. It can give you better questions, not the final answer.
AI and health questions. Good for: explaining medical jargon; preparing questions for your doctor; putting a leaflet into plainer words. Not good for: diagnosing you; changing medicines or doses; emergencies, when you should call 911 in the USA or 999 in the UK first. Always check with your doctor or pharmacist.
What AI can and can't help with when it comes to your health.

How Do I Ask AI About My Health Safely?

  1. Give context, not identity. Your age and symptoms help. Your name, date of birth and medical record numbers aren't needed.
  2. Ask it to explain its reasons and to tell you when you should see a doctor.
  3. Ask for sources and check them against trusted sites (below).
  4. Treat "you should see a doctor" seriously. If AI suggests getting checked, do it. If it reassures you but you still feel unwell, trust your instincts and get checked anyway.
  5. Take your notes to the appointment. Saying "I read that..." is fine. Good doctors welcome questions.

What Is A Good Health Question To Copy?

"I'm 68 and my doctor said my cholesterol is a bit high. In simple terms, what does that mean, what questions should I ask at my next appointment, and what would mean I need to call sooner?"

Where Can I Double-Check Health Information?

USA

MedlinePlus from the National Library of Medicine, and the CDC. Your pharmacist can answer medicine questions for free.

UK

The NHS website covers conditions and medicines in simple terms. Your local pharmacist can also give free advice.

How Do I Keep My Health Details Private?

Health information is some of the most personal data you have. Before you share test results or photos, cover your name, address and ID numbers. If you'd rather a chat isn't saved, ChatGPT's Temporary Chat isn't kept in your history. See Does ChatGPT remember what you tell it?

Common Questions

Should I trust ChatGPT about my symptoms?

Use it to understand, not to decide. It can help you know what questions to ask, but only a doctor, nurse or pharmacist who knows you should decide what to do.

It keeps telling me to see a doctor. Is it overreacting?

AI tools are designed to be cautious, and that's a good thing. If you're unsure, a pharmacist or a non-emergency phone line is a quick middle step.

Can I upload my test results?

You can, but cover your name and ID numbers first, and remember the AI may misread them. Your doctor's explanation always comes first.
