What should you know about risk of preeclampsia second pregnancy?

Pre-eclampsia is a pregnancy complication involving high blood pressure and signs that organs such as the kidneys or liver are under strain. It can affect the pregnant person and the baby, and it may develop after the middle of pregnancy or after birth. A previous diagnosis, especially if it began early or was severe, helps the maternity team decide how closely to monitor a new pregnancy. It does not by itself confirm that pre-eclampsia will return.

Routine checks may include blood pressure, urine testing, blood tests, questions about symptoms, and assessment of the baby's growth and wellbeing. Some people have few symptoms, which is why scheduled antenatal care remains useful even when you feel well.

Contact an antenatal service early and describe exactly what happened in the previous pregnancy, including when high blood pressure began, whether treatment or early birth was needed, and whether symptoms continued after delivery. Keep monitoring appointments and take any recommended preventive medicine only as prescribed. Record home blood pressure readings if your clinician asks you to, using the technique they explain. If pre-eclampsia develops, management may include closer observation, medication, hospital care, and planning induction of labour or cesarean section when birth is safer than continuing the pregnancy.

Contact your maternity unit urgently for a severe or persistent headache, visual changes, pain under the ribs or in the upper abdomen, sudden swelling of the face or hands, breathlessness, vomiting, or feeling markedly unwell. Reduced fetal movement also needs prompt assessment. Seizure, collapse, severe breathing difficulty, or intense pain is an emergency; call emergency services.

How does my previous pre-eclampsia affect this pregnancy? Should I use home blood pressure monitoring or preventive medicine? Which symptoms require same-day assessment? How will the baby's growth and placental function be followed?
