Using AI for health questions: what’s safe
AI can explain a hospital letter and help you prepare for a GP appointment. It can’t diagnose you or replace NHS advice. Here’s where the line is.
Video transcript
AI can be a real help with health questions, as long as you know where the line is. Here’s what it’s good for, and what it isn’t.
It’s good at explaining. It can decode the words in a hospital letter, help you prepare for an appointment and put NHS information into plain English. But it isn’t a doctor, and it can’t diagnose you.
If it’s an emergency, don’t type: call nine nine nine. For urgent advice, use NHS one one one, online or by phone. A chatbot can’t examine you, and it shouldn’t be the one deciding.
One of the best uses is getting ready for your GP. Describe what’s been happening, ask it not to diagnose you, and get a short summary and a list of questions to take along.
Remember, AI predicts likely words. It can sound completely confident and still be wrong, and it may simply agree with you. Check anything that matters on the NHS website, or ask your pharmacist.
And think before you share. Health details are personal, so check the app’s privacy settings and leave out anything that identifies you.
Read the full guide below for safe prompts you can copy, including one to prepare for your next GP appointment.
In 30 seconds
- AI can explain medical words and help you prepare questions for your GP.
- It can’t diagnose you. In an emergency, call 999. For urgent advice, use NHS 111.
- It can sound sure and be wrong, so check the NHS website and think before you share.
A letter arrives after a hospital scan. It calls the findings “unremarkable” and mentions something “bilateral”, and your GP appointment isn’t until next week. Ask an Jargon busterAI assistant: A chat app such as ChatGPT, Claude or Gemini that answers questions and does tasks you describe in plain language. and it will tell you, in seconds, that these mean “nothing unusual found” and “on both sides”.
What it’s good for, and what it isn’t
That’s the kind of job AI does well: explaining and organising. It isn’t a doctor, though. It can’t examine you, it doesn’t know your history and it can be wrong while sounding completely sure.
| Good uses | Not a job for AI |
|---|---|
| Explaining the medical words in a letter | Working out what’s wrong with you |
| Preparing questions for your GP | Emergencies: call 999 |
| Putting NHS information into plain English | Urgent advice: use NHS 111 |
| Building a realistic sleep or exercise routine | Starting, stopping or changing medication |
Get ready for your GP appointment
Appointments are short, so it pays to arrive prepared. Describe what’s been happening and ask AI to put it in order: when it started, how often it happens, what helps and what makes it worse.
I have a GP appointment about [symptom or condition]. Here’s what’s been happening: [when it started, how often, what helps, what makes it worse]. Please don’t diagnose me. Help me write a short summary I can read out in under a minute, and list five questions to ask my GP, most important first.
You can do the same with a letter. Remove your name, date of birth and NHS number, paste in the rest and ask what each medical word means.
Explain this hospital letter in plain English. Go through each medical term and say what it means in everyday words. Don’t guess at anything the letter doesn’t say. Finish with three questions I could ask my doctor about it. [Paste the letter, with your name, date of birth and NHS number removed]
It can also help you build a routine you’ll stick to, such as a ten-minute walk after lunch that grows each week, or a calmer wind-down before bed. If you have a health condition, check with your GP first.
Why you should always check
AI predicts what a good answer sounds like rather than looking it up. When it states something false as fact, it’s called a Jargon busterHallucination: When AI states something false as if it were true, because it predicts plausible words rather than checking facts., and it sounds just as sure either way.
It may also agree with whatever you suggest, a habit called Jargon busterSycophancy: When an AI tells you what you want to hear, agreeing with you instead of giving an honest view.. Ask “is this just a cold?” and it may simply reassure you. Check anything that matters on the NHS website, and ask a pharmacist or your GP about medicines.
Think before you share
Health details are among the most personal things about you. Before you type, check the app’s privacy settings, including whether your chats are used for Jargon busterTraining: The stage where AI learns, by finding patterns in a huge number of examples.. Leave out anything that identifies you, and don’t share someone else’s health details without asking them.
Used this way, AI is a calm explainer and a useful notepad, not a doctor. For more, read is AI safe to use? and why AI gets things wrong.
