What is Preeclampsia?

Preeclampsia is a serious condition that can affect you anytime after the 20th week of pregnancy and up to 6 weeks after your baby is born. You can develop postpartum preeclampsia even if you never had high blood pressure during your pregnancy.

Because preeclampsia often develops quietly, you may not notice symptoms right away. But it can progress quickly, which is why recognizing the early signs and getting timely care is essential for both your health and your baby’s.

Symptoms

Whether you’re pregnant or recovering after giving birth, you should watch for symptoms such as:

  • High blood pressure
  • Protein in your urine
  • Persistent or severe headaches
  • Blurred vision or seeing spots
  • Swelling in your face or hands
  • Shortness of breath
  • Pain in the upper right abdomen
  • Sudden weight gain from fluid retention

After delivery, symptoms may also include:

  • New or worsening headaches
  • Vision changes
  • Chest pain or difficulty breathing
  • Sudden swelling

How Preeclampsia is Diagnosed?

Your prenatal visits help catch preeclampsia early. At each appointment, your provider checks your blood pressure, reviews any symptoms you’re experiencing, and may test your urine for protein.

If symptoms appear after birth, you may have your blood pressure checked, along with urine tests and bloodwork, to diagnose postpartum preeclampsia.

How Preeclampsia Affects You, During and After Pregnancy

Preeclampsia can place stress on your organs and the placenta. During pregnancy, it may lead to:

  • Slowed fetal growth
  • Low birth weight
  • Preterm labor
  • Placental abruption
  • Organ complications if the condition becomes severe

Even after your baby is born, postpartum preeclampsia can develop or worsen. If untreated, it can lead to seizures, stroke, or lasting organ damage. That’s why paying attention to new symptoms after delivery is just as important as during pregnancy.

How is Preeclampsia Treated?

If you’re diagnosed with preeclampsia, your doctor will create a personalized treatment plan, which may include:

  • More frequent prenatal visits
  • Medication to reduce blood pressure
  • Rest or activity adjustments
  • Regular lab work
  • Ultrasounds to monitor your baby’s growth
  • Planning for early delivery if needed

If you develop postpartum preeclampsia, you may need medication to lower your blood pressure, magnesium sulfate to prevent seizures, and close follow‑up to ensure your levels return to normal.

What Could Happen if Preeclampsia is Left Untreated?

Without treatment, preeclampsia can become life‑threatening. Untreated preeclampsia may cause:

  • Eclampsia (seizures)
  • Stroke
  • Heart, liver, or kidney damage
  • Placental abruption
  • Long-term health complications
  • Emergency delivery
  • Stillbirth, in severe cases

Untreated postpartum preeclampsia can escalate quickly, leading to seizures or stroke even days or weeks after birth. Early treatment greatly reduces these risks.

What Expectant Moms Often Want to Know About Preeclampsia

What are some common risk factors for preeclampsia? 

You may be at higher risk if you:

  • Had preeclampsia in a past pregnancy
  • Have chronic high blood pressure
  • Are pregnant with more than one baby
  • Have type 1 or type 2 diabetes, kidney disease, or certain autoimmune disorders
  • Are African American
  • Have a family history of preeclampsia
  • Have a BMI of 30 or higher
How can you prevent or reduce your risk of preeclampsia? 

You can help lower your risk by:

  • Attending all prenatal appointments
  • Reporting unusual symptoms right away
  • Eating a nutrient‑dense diet
  • Avoiding sugary and processed foods
  • Staying active with doctor‑approved exercise
  • Maintaining a healthy weight
  • Asking your doctor whether a daily low‑dose aspirin is right for you
What causes preeclampsia? 

The exact cause is unknown, but experts believe it begins in the placenta when its blood supply doesn’t develop normally. Genetics may also play a role.

How can you manage preeclampsia during pregnancy? 

Management may include rest, medication, frequent monitoring, lab work, and ultrasounds.

How does preeclampsia affect your pregnancy and your baby? 

If not managed, it can cause oxygen restriction, organ damage, eclampsia, HELLP syndrome, and placental abruption.

If you have preeclampsia, can you carry your baby to full term? 

It depends on severity and your baby’s health. Delivery at 37 weeks is common for mild cases; earlier delivery may be needed for severe cases.

Do preeclampsia symptoms go away after your baby is born? 

Most improve within six weeks, but postpartum preeclampsia can still occur and requires monitoring.

Would I see an MFM doctor in addition to my OB-GYN? 

You’ll continue seeing your OB‑GYN, and you’ll also meet with a Maternal‑Fetal Medicine Specialist who provides extra monitoring and expertise when your pregnancy needs additional support.

Why You May Need to See a Maternal-Fetal Medicine Specialist

If you're diagnosed with preeclampsia, seeing an specialist gives you an extra level of expert care. These doctors focus specifically on high‑risk pregnancies, so they understand how preeclampsia affects both you and your baby, and what needs to happen to keep you safe.

You may be referred to a maternal–fetal medicine specialist if you:

  • Have high blood pressure
  • Show symptoms of preeclampsia or postpartum preeclampsia
  • Had preeclampsia in a previous pregnancy
  • Have underlying conditions that increase your risk

When you meet with an Maternal-Fetal Medicine specialist, you receive more:

  • advanced monitoring
  • detailed ultrasounds
  • and a personalized care plan designed around your unique risks

Your MFM stays closely connected with your OB‑GYN and helps guide decisions about testing, treatment, and the safest timing for delivery. You’ll continue seeing your OB‑GYN, with the MFM adding extra monitoring and expertise when your pregnancy needs additional support.

Because preeclampsia can change quickly, having an MFM specialist on your team ensures someone is watching for even the smallest shifts in your condition.

They help you stay pregnant safely for as long as possible, lower the risk of severe complications, and prepare you for delivery, whether you're still pregnant or recovering after birth. They also understand postpartum preeclampsia and can help protect your health after your baby arrives.
