Rare diseases can take years to diagnose. Each symptom on its own can look ordinary, and each appointment sees only one piece. A complete history, including your family and the pattern over time, helps a doctor see the whole picture.

1 in 17 people are affected by a rare disease at some point in their life: over 3.5 million people in the UK. Department of Health and Social Care: The UK Rare Diseases Framework, Published 9 January 2021

How Hea helps

Your history, in order Today

Hea asks the urgent questions first, then the questions a GP would ask about your symptom, including your family's health where guidance says it matters. Your own words are kept.

The pattern over time Today

How long each problem has lasted and what you've tried go into the note. When you ask your AI to go through the case, Hea adds a timeline from what it has: when it started, earlier notes, results the lab marked, and your medicines and conditions.

Questions about a referral Today

Your own questions for the doctor go into the note, such as whether a specialist could help. Hea can also show recent research reviews about a condition, about people in general.

Questions people ask

What counts as a rare disease?

In the UK, a rare disease is one that affects fewer than 1 in 2,000 people. There are over 7,000 of them, and together they affect 1 in 17 people at some point in their life.

Why do rare diseases take so long to diagnose?

Each one is uncommon, and the path can involve several referrals, tests that give no clear answer and sometimes a wrong diagnosis first. The UK Rare Diseases Framework says it can take years to get a final diagnosis.

How do I talk to my GP about a rare condition?

Bring your whole history in order: each symptom, when it started, how it has changed, what you've tried and who in your family has had similar problems. Ask plainly whether a referral to a specialist would help. NICE suggests thinking beforehand about what matters to you and the questions you want to ask.

Can I get genetic testing on the NHS?

Only if a doctor refers you. NHS genetic and genomic testing is mainly used to diagnose rare and inherited conditions and some cancers, and it's free on the NHS when a hospital specialist refers you.

Does Hea diagnose rare diseases?

No. Hea gathers the history a specialist needs and writes it as a note for your GP, and the note names no condition. Your GP or a specialist decides what to look into.
