Predicting pre-eclampsia

At antenatal visits, clinicians ask about previous pre-eclampsia, high blood pressure, kidney disease, diabetes, autoimmune disease and multiple pregnancy. They measure blood pressure and may test urine for protein. Some services combine these findings with blood tests and ultrasound measurements to estimate risk. A risk assessment does not confirm the condition; it helps decide how closely you should be monitored and whether preventive treatment should be discussed.

Tell your maternity team about medical conditions, medicines and pregnancy history early. Attend scheduled checks and keep a record of symptoms and blood pressure readings if home monitoring is advised. Do not start aspirin or other medicines on your own; the timing and dose must be chosen for your situation. Regular antenatal care supports timely testing and planning. Read about [Antenatal Care Package](/treatments/pregnancy-and-birth-care/antenatal-care-package/) and [Pre-eclampsia](/conditions/pre-eclampsia/).

Contact your maternity team urgently for a severe or persistent headache, vision changes, severe pain below the ribs, sudden swelling of the face or hands, breathlessness, vomiting that feels unusual, or reduced fetal movement. High blood pressure found at home also needs prompt clinical advice. These symptoms require assessment because pre-eclampsia can affect several organs and may worsen without obvious warning.

What factors place me at higher risk? Should I monitor blood pressure at home? Which symptoms require an immediate call, and when should I repeat testing?
