What is Preeclampsia?

Preeclampsia is a serious pregnancy complication that causes high blood pressure and can cause damage to the liver and kidneys. It typically develops after 20 weeks of pregnancy. If left untreated, preeclampsia can lead to serious complications for both mother and baby.

University of Rochester Medicine's maternal-fetal medicine experts, cardiologists, and high-risk pregnancy specialists provide personalized care for preeclampsia.

What Are the Symptoms of Preeclampsia?

Common symptoms of preeclampsia include:

  • High blood pressure (140/90 mmHg or higher)
  • Protein in urine (proteinuria)
  • Severe headaches that don't respond to medication
  • Vision changes including blurred vision, light sensitivity, or temporary vision loss
  • Upper abdominal pain, usually under the ribs on the right side
  • Nausea or vomiting in the second half of pregnancy
  • Decreased urine output
  • Sudden weight gain and swelling (edema), particularly in the face and hands
  • Shortness of breath caused by fluid in the lungs

If you experience any of the above symptoms, contact your healthcare provider immediately.

Emergency Warning Signs

Seek immediate medical attention if you experience:

  • Severe, persistent headache
  • Visual disturbances
  • Severe upper abdominal pain
  • Difficulty breathing
  • Seizures (a sign of eclampsia, a life-threatening complication)

    Who is at Risk for Preeclampsia?

    While preeclampsia can affect anyone who is pregnant, certain factors increase your risk.

    Treatments for Preeclampsia

    University of Rochester Medicine experts create personalized treatment plans that prioritize both maternal and fetal health. Our goal is to prepare and inform you through every step of your journey.

    How is Preeclampsia Diagnosed?

    Our high-risk pregnancy specialists use comprehensive diagnostic approaches:

    • Blood pressure monitoring at each prenatal visit and between visits when symptoms arise
    • Urine tests to check for protein levels
    • Blood tests to assess:
      • Kidney function (creatinine levels)
      • Liver function (liver enzyme levels)
      • Platelet count
      • Blood clotting factors
    • Fetal ultrasound to monitor baby's growth and amniotic fluid levels
    • Nonstress test or biophysical profile to check baby's heart rate and movement
    • Doppler ultrasound to evaluate blood flow to the placenta

    How is Preeclampsia Treated?

    Treatment for preeclampsia depends on the severity of your condition and how far you are in your pregnancy.

    Monitoring & Management

    For non-severe preeclampsia, your care may include:

    • Frequent prenatal visits for close monitoring
    • Blood pressure checks at home and in the office
    • Regular blood and urine tests
    • Fetal monitoring to track your baby's wellbeing
    • Activity modification including bed rest when appropriate

    For severe preeclampsia, you will likely need to be admitted to the hospital.

    Medications

    • Antihypertensive medications to manage blood pressure
    • Corticosteroids to help mature your baby's lungs if early delivery is anticipated
    • Magnesium sulfate to prevent seizures in severe cases
    • Anticonvulsants if eclampsia develops

    Delivery

    The only cure for preeclampsia is delivery of the baby. Your care team will determine the best time for delivery:

    • Severity of your condition
    • Your baby's gestational age and development
    • Response to treatment
    • Fetal wellbeing

    For severe preeclampsia or complications, delivery may be recommended even if your baby is premature. Our neonatal intensive care unit (NICU) provides expert care for premature infants.
