Postpartum Preeclampsia: Signs and When to Act

Preeclampsia does not always end—or begin—with delivery. Postpartum preeclampsia is a serious blood-pressure disorder that can develop after birth, including in someone whose blood pressure was normal during pregnancy. It most often appears within days, but it can occur up to six weeks postpartum.

Because untreated preeclampsia can lead to seizures, stroke and organ injury, new warning signs after birth need prompt attention.

What is postpartum preeclampsia?

Preeclampsia involves high blood pressure plus signs that organs such as the brain, liver, kidneys or blood-clotting system may be affected. Postpartum symptoms can be mistaken for exhaustion, migraine, normal swelling or recovery from birth. A blood-pressure measurement and clinical assessment help separate these possibilities.

Warning signs after birth

Contact your maternity team or seek urgent medical assessment for:

• a severe headache or one that does not improve;
• blurred vision, flashing lights, spots or unusual light sensitivity;
• pain in the upper abdomen or shoulder, especially on the right;
• shortness of breath, chest tightness or difficulty breathing when lying down;
• sudden or marked swelling of the face or hands;
• nausea or vomiting that feels new or severe;
• a sense that something is seriously wrong; or
• an elevated home blood-pressure reading according to your discharge plan.

Do not wait for every symptom. Preeclampsia can also be present with few symptoms.

When is it an emergency?

Call local emergency services for a seizure, loss of consciousness, severe breathing difficulty, chest pain, sudden weakness or numbness, difficulty speaking, or a very severe headache with neurological symptoms.

If you have been given blood-pressure thresholds by your maternity team, follow them. ACOG patient guidance advises calling promptly for a reading of 140/90 mm Hg or higher after birth. A reading of 160/110 mm Hg or higher is generally treated as severe and requires immediate clinical attention. Do not repeatedly recheck a severe reading for hours before seeking help.

Who can develop it?

Risk is higher after preeclampsia or high blood pressure in pregnancy, but postpartum preeclampsia can occur without that history. Other risk factors may include chronic hypertension, kidney disease, diabetes, obesity, multiple pregnancy and certain autoimmune conditions. Risk factors are not a screening test: people without them can still become unwell.

What evaluation and treatment may involve

A clinical team may repeat blood-pressure readings and order urine or blood tests. Treatment can include medicines to lower blood pressure and magnesium sulfate to reduce seizure risk in selected cases. Some people need hospital monitoring.

If you are breastfeeding, tell the team, but do not delay care. Clinicians can select treatments with lactation in mind.

Follow-up after preeclampsia

If you had high blood pressure or preeclampsia, follow the blood-pressure monitoring plan given at discharge. ACOG notes that some people need home monitoring for one to two weeks. Longer-term, keep preeclampsia in your medical history because it is linked with a higher future risk of hypertension, heart disease, stroke and kidney disease.

A note for partners and family

Recovery after birth can make it hard to judge symptoms. Partners can help by knowing the warning signs, taking concerns seriously, locating the blood-pressure cuff if prescribed and arranging urgent transport or emergency help when needed.

The takeaway

New headache, vision changes, upper-abdominal pain, breathing difficulty or high blood pressure after birth should never be dismissed as “just postpartum.” Prompt assessment can prevent serious complications.
