Preeclampsia
Serious pregnancy complication causing high blood pressure and organ damage, typically after 20 weeks.
Affects: Affects 5-8% of pregnancies
Overview
Preeclampsia is a serious condition characterized by high blood pressure and signs of damage to organs, most often the liver and kidneys. It typically develops after 20 weeks of pregnancy and can progress rapidly.
The only cure for preeclampsia is delivery of the baby, though symptoms may persist postpartum. Mild preeclampsia can be managed with careful monitoring, while severe preeclampsia requires immediate treatment and often early delivery.
Without treatment, preeclampsia can lead to serious complications for both mother and baby including seizures (eclampsia), stroke, organ failure, and placental abruption. Early detection through prenatal care is crucial.

🔬 Diagnosis
- →Blood pressure readings over 140/90 on two occasions
- →Protein in urine (24-hour collection or protein/creatinine ratio)
- →Blood tests checking liver enzymes, kidney function, platelets
- →Checking for signs of organ damage

💊 Treatment
- ✓Mild: Close monitoring, blood pressure checks, urine tests, fetal monitoring
- ✓Moderate: Bed rest, limited activity, frequent appointments
- ✓Severe: Hospitalization, IV magnesium sulfate to prevent seizures
- ✓Blood pressure medication
- ✓Corticosteroids for baby's lung development if early delivery needed
- ✓Delivery is only cure - timing depends on severity and gestational age
- ✓After delivery: Continue monitoring, medications may be needed
- ✓Postpartum preeclampsia can occur up to 6 weeks after delivery
🛡️ Prevention

❓ Frequently Asked Questions
What are the warning signs of preeclampsia?
The classic warning signs of preeclampsia are: a severe headache that does not respond to acetaminophen, vision changes (blurry vision, seeing spots or flashing lights, light sensitivity), sudden swelling of the face or hands, pain in the upper right abdomen (under the ribs, where the liver sits), sudden weight gain of more than 2–5 pounds in a week, and shortness of breath. High blood pressure and protein in the urine are usually found at a prenatal visit before you feel symptoms, which is why regular prenatal appointments are essential — preeclampsia often has no obvious early warning signs.
What blood pressure reading indicates preeclampsia?
Preeclampsia is diagnosed when blood pressure is 140/90 mmHg or higher on two separate readings at least 4 hours apart, after 20 weeks of pregnancy, plus protein in the urine or evidence of organ damage (liver, kidneys, brain, or blood clotting). Severe preeclampsia is defined as a reading of 160/110 mmHg or higher, which requires immediate hospitalization and treatment. A single high reading does not make the diagnosis — it must be confirmed on a repeat reading.
Can preeclampsia harm the baby?
Yes. Preeclampsia reduces blood flow to the placenta, which restricts oxygen and nutrients reaching the baby. This can cause fetal growth restriction (the baby grows too slowly), low amniotic fluid, and in severe cases placental abruption or preterm delivery. Babies born to mothers with severe preeclampsia or eclampsia are at higher risk of complications from prematurity. With close monitoring and timely delivery at the right gestational age, most babies do well.
What is the treatment for preeclampsia?
The only cure for preeclampsia is delivery of the baby and placenta. For mild preeclampsia at or near term (37+ weeks), delivery is typically recommended promptly. Before 37 weeks, treatment depends on severity: mild cases may be managed with bed rest, blood pressure monitoring, and twice-weekly fetal monitoring while waiting for the baby to mature; severe cases require hospitalization, intravenous magnesium sulfate to prevent seizures, antihypertensive medication, and often early delivery. Decisions about timing involve weighing maternal safety against risks of prematurity for the baby.
Does preeclampsia go away after delivery?
Usually yes, but not always immediately. Blood pressure and symptoms typically begin to resolve within days to weeks after delivery. However, preeclampsia can actually worsen or first appear postpartum — called postpartum preeclampsia — up to 6 weeks after birth. Signs of postpartum preeclampsia (severe headache, vision changes, upper abdominal pain, swelling) after delivery warrant an emergency room visit. Women who had preeclampsia also have a 20–50% recurrence risk in future pregnancies and a significantly elevated lifetime risk of cardiovascular disease — something to discuss with a doctor for long-term health monitoring.
