Pre-eclampsia: Why Your Pregnancy Story Is Research Data

Every figure in this guide comes from a published source, linked where it appears and kept in CureCircle's evidence base with the source's own words. It is not medical advice. Read on 7 November 2026.

Pre-eclampsia can turn a routine pregnancy into an emergency within days: high blood pressure, protein in the urine, headaches, swelling, and sometimes an early delivery. Researchers are still working out who is at risk, how to spot it sooner, and what it means for the mother's health in the years after. The records from those weeks, and the mother's own account of the signs and what followed, are what that research needs.

How many women it affects

According to the WHO, "pre-eclampsia is a hypertensive disorder that affects 3-8% of women who give birth worldwide". The Global Burden of Disease study counted 18.08 million new cases of hypertensive disorders of pregnancy in 2019.

The records worth keeping

NICE's guideline on hypertension in pregnancy describes the tests that leave records:

• A PLGF-based blood test to help rule out pre-eclampsia between 20 and 37 weeks.
• Blood tests twice a week: full blood count, liver function and renal function.
• Scans of the baby at diagnosis and, if normal, every 2 weeks.
• A urine test after the birth, 6 to 8 weeks after.

Home blood pressure readings, and your notes on headaches, swelling and how you felt, show what the appointments missed. If you do not have your maternity notes, ask your maternity unit for a copy.

What sharing it is worth

CureCircle values every contribution with a public benchmark built from what health data has sold for. A complete pre-eclampsia story with the records the guideline lists comes to about $62 per licence on the benchmark today, and about $264 per licence with 60 days of blood pressure or symptom diary entries. Every line and its source is on the pre-eclampsia page.

A licence is not a one-off sale: the same de-identified story can be licensed to several research teams, and you earn a share each time.

How to share it

You start by writing what you went through in your own words; a few quick questions follow, then an AI interviewer asks about the details only you know, and you rate every treatment you had. You can add maternity notes, test results and blood pressure records as PDFs or photos, and the AI reads them into your own medical file. Partners can share what they saw, with permission. Before anything is shared, you read the de-identified summary and decide.
