What is Pre-eclampsia?
Pre-eclampsia is a pregnancy condition involving high blood pressure and signs of organ stress, usually detected through protein in the urine, typically developing after 20 weeks. Its exact cause isn't fully understood, but it's related to problems with the blood supply to the placenta.
It's picked up through routine blood pressure checks and urine tests at antenatal visits, which is why these are done so regularly. If untreated, it can become serious for both the pregnant person and the baby, but with monitoring and, when needed, early delivery, most cases are managed safely.
02 · Understand
Clinical context
This is why blood pressure and urine are checked so often
Routine antenatal checks are specifically designed to catch pre-eclampsia early, often before symptoms even develop, which is why attending every scheduled appointment matters.

Practical steps
This Requires Medical Monitoring and Treatment, Not Home Management

- 2Know the warning signs.Headache, visual changes, upper abdominal pain, and swelling are all worth reporting promptly.
- 3Monitor your baby's movements.Report any reduction in your baby's usual pattern of movement without delay.

A severe headache, visual changes, or upper abdominal pain should always be treated as urgent, even if you feel otherwise well.
