How to navigate Pre-eclampsia: risk, warning signs, and specialist care
An educational path from the first question to the next step. It does not replace individual assessment.
- 01Recognise the finding
Name the maternal, fetal, placental, or pregnancy concern precisely.
- 02Confirm what it means
Check gestation, diagnostic criteria, severity, and possible alternatives.
- 03Stratify risk
Identify what changes maternal safety, fetal wellbeing, timing, or prognosis.
- 04Plan surveillance
Match monitoring intensity to the condition and how quickly it can change.
- 05Escalate when needed
Refer, admit, treat, or plan birth when thresholds are reached.
Visual decision pathway
Suspected pre-eclampsia: assess, classify, act
Blood pressure is one part of the decision; symptoms, laboratory results, placental function and fetal condition complete the picture.
- ConfirmMeasure and reassess
Repeat blood pressure correctly and review gestation, history and medication.
- EvaluateLook for organ or placental dysfunction
Symptoms, urine protein, blood count, liver, kidney and fetal assessment.
- ClassifyStable or severe?
Identify severe features, progression and whether outpatient care is safe.
- BalanceTreat, monitor or deliver
Balance maternal deterioration against prematurity with a documented escalation plan.
Pre-eclampsia is a pregnancy-specific disorder usually recognised after 20 weeks through new high blood pressure together with protein in the urine, maternal organ dysfunction, or evidence that the placenta is not supporting the pregnancy normally. It ranges from a condition managed with close outpatient surveillance to a medical emergency requiring admission and delivery.
Who is at increased risk?
Risk is higher after previous pre-eclampsia, particularly when it was early or severe; in chronic hypertension, kidney disease, diabetes, autoimmune disease, multifetal pregnancy, or certain first pregnancies. Risk assessment early in pregnancy can identify women who may benefit from preventive strategies such as low-dose aspirin, but treatment should be prescribed by the treating clinician after reviewing contraindications and timing.
What monitoring may include
Assessment can include repeated blood pressure measurement, urine protein, blood counts, liver and kidney tests, symptom review, fetal growth ultrasound, amniotic-fluid assessment, and Doppler studies. The purpose is not to repeat tests mechanically. It is to detect whether maternal disease or placental dysfunction is progressing and to decide whether continuing the pregnancy remains safer than delivery.
Warning signs
Severe or persistent headache, visual disturbance, severe pain below the ribs or in the upper abdomen, sudden marked swelling, chest pain, breathlessness, seizures, heavy bleeding, or reduced fetal movements needs urgent clinical assessment. A home blood pressure reading of 140/90 mmHg or higher should prompt contact with the maternity team; a severely elevated reading or serious symptoms requires urgent care.
The delivery decision
Delivery is the definitive way to end the pregnancy process driving pre-eclampsia, but timing depends on gestation, severity, maternal laboratory findings, blood pressure control, fetal condition, and available neonatal support. Before term, the team balances the maternal risk of waiting against the fetal consequences of prematurity. That decision is individual and can change quickly, which is why a documented escalation plan matters.
