Can You Ask an AI About Health? A Guide to What's Safe

When you have a health worry, especially late at night, it can be very tempting to type your symptoms into an AI chatbot. It's quick and it's private. But is it safe?

It can be helpful for general information, but it is never a substitute for a proper doctor.

The Golden Rule: AI is not a doctor

This is the most important thing to remember. An AI chatbot has not trained for years in medicine, it doesn't know your history, and it cannot examine you. It is a language tool that gives answers based on patterns in data. This means it can be wrong, out of date, or sound confident about something that isn't true.

Never use an AI to diagnose a symptom, and never change your medication based on what it says. We've found that when you push AI for a specific answer about symptoms, it tends to list several possible conditions, which can cause more anxiety than relief.

When you should always see a professional

If you have a symptom that is severe, sudden, or has been worrying you for a while, please don't rely on an AI. Contact your GP surgery. If it's urgent and your GP is closed, you can call NHS 111, and they will guide you to the right service.

So, what is it useful for?

Once you're clear that it's not a doctor, an AI can be quite a useful helper for a few specific things. If you're nervous about using AI at all, our guide to common fears about AI addresses many of the concerns people raise when starting out:

• Explaining things simply. It's very good at translating medical jargon into plain English.
• Preparing for an appointment. It can help you organise a list of symptoms or think of questions to ask your GP, so you don't forget anything.
• General health knowledge. You can ask it for healthy recipe ideas, or simple exercise plans, or ways to improve your sleep.

Helpful questions to copy and paste

Notice that these are all general questions. It's the safest way to use it.

• "Can you explain what 'high blood pressure' means in simple terms?"
• "What are some good questions to ask my GP about a new medication?"
• "Help me write down my symptoms clearly for a doctor's visit. They are: [list symptoms without any personal names or details]."
• "What are some gentle ways for someone over 60 to build walking into their routine?"

A note on privacy

Never share your name, address, NHS number, or detailed medical history in an AI chat. To be safe, keep your questions general. Your health information is private and should only be shared with your healthcare team. For more on what to share safely when using AI, see our guide to staying safe with AI.
