Preeclampsia Warning Signs During Pregnancy and After Birth
Preeclampsia can develop after 20 weeks of pregnancy and may continue or appear after birth. Learn which symptoms need urgent care, how clinicians assess it and what to ask at follow-up.

What is preeclampsia, and when can it happen?
Preeclampsia is a serious pregnancy-related blood-pressure disorder that usually begins after 20 weeks. It can affect the pregnant woman’s organs and the baby, and it can progress to seizures. It may also continue or first become noticeable after birth, so new severe symptoms after delivery need medical assessment.
Routine checks matter even when you feel well
Some people have no clear warning symptoms. Antenatal blood-pressure checks and urine testing can help a clinician identify a problem. Attend scheduled pregnancy visits where possible, and ask when and where the next check will happen if travel, cost, work or childcare makes attendance difficult.
Know the warning signs
Seek urgent medical advice for a severe or persistent headache, blurred vision or flashing spots, severe pain under the ribs or in the upper abdomen, sudden swelling of the face or hands, breathing difficulty, or feeling very unwell. These signs can have other causes, but they should not be dismissed during pregnancy or after birth.
A seizure, collapse or severe breathing problem is an emergency
Call 112 or go to the nearest emergency department now. Do not wait to measure blood pressure at home or to see whether rest makes a severe symptom disappear.

How is preeclampsia assessed?
A clinician considers blood pressure, pregnancy timing, symptoms and signs that organs may be affected. One home reading or a symptom search cannot diagnose or rule out preeclampsia.
Tell the team when symptoms started
Share any severe headache, vision changes, upper abdominal pain, swelling, breathlessness, reduced urine or sudden change in how you feel. Mention whether you are pregnant or recently gave birth, and bring your antenatal card or discharge papers if they are easy to reach.
Ask what checks are needed now
The team may repeat blood pressure, test urine and blood, and assess the pregnancy or baby. Ask what the results mean, whether you need observation or admission, which symptoms mean you should return immediately and how to contact the service.
Do not start prevention or blood-pressure medicine yourself
A clinician may discuss a preventive medicine or treatment based on personal risk and test results. Do not start aspirin, calcium tablets, blood-pressure medicines or someone else’s prescription without medical advice, and do not stop a prescribed medicine abruptly.
Treatment and care after delivery
Care depends on severity, pregnancy stage, test results and the health of the woman and baby. The team may monitor closely, use medicines or recommend delivery when that is the safest option. Only the treating team can weigh those choices for a particular pregnancy.
Ask for the reason behind each recommendation
Request a plain-language explanation of the risk being addressed, available options, likely monitoring and what may happen if the plan changes. You can ask who will support communication or help you understand the decision.
Keep blood-pressure follow-up after birth
Discharge does not mean every pregnancy-related blood-pressure problem has ended. Ask when your blood pressure should be checked again, who will review it, which medicine is safe for you and breastfeeding if relevant, and when to seek urgent care.
Make space for the woman’s consent and questions
A family member can help with transport or notes if invited, but should not answer every question for her. Ask staff for a private conversation if pressure, fear or control at home makes it hard to describe symptoms or follow a care plan.
Preeclampsia: frequently asked questions
Can preeclampsia happen after the baby is born?
Yes. A pregnancy-related blood-pressure disorder can continue or become apparent after delivery. New severe headache, vision changes, upper abdominal pain, breathing problems, seizure or collapse needs urgent assessment.
Can I have preeclampsia without noticing symptoms?
Yes. Some people have few or no symptoms, which is one reason antenatal checks matter. Do not wait for symptoms before attending recommended blood-pressure and urine checks.
Does swelling alone prove preeclampsia?
No. Swelling can occur for different reasons, and it cannot diagnose the condition. Sudden swelling with other warning signs or feeling unwell should be reported promptly.
Should I take aspirin or calcium to prevent it?
Only if a qualified clinician recommends it for your circumstances. Prevention advice depends on individual risk, timing and local clinical guidance; self-prescribing is not a safe substitute for antenatal care.
Words you can use
Ask for an urgent blood-pressure review
A severe or unusual symptom starts during pregnancy or after birth

My last blood-pressure reading was [if known]. Please tell me where to be assessed now. If I have a seizure, collapse or severe breathing problem, we are calling 112.”
