Preeclampsia/Eclampsia
What is Preeclampsia/Eclampsia?
Preeclampsia is a pregnancy complication that causes high blood pressure and signs of organ damage. It typically develops after 20 weeks of pregnancy in women whose blood pressure was previously normal. The condition affects blood vessels throughout the body, making it harder for organs to get the oxygen and nutrients they need.
Eclampsia is the severe form of preeclampsia that involves seizures. It can develop when preeclampsia goes untreated or becomes life-threatening. Both conditions require immediate medical attention to protect the health of mother and baby.
Preeclampsia affects about 5 to 8 percent of all pregnancies worldwide. Early detection through blood pressure monitoring and blood tests can help prevent progression to more dangerous stages. With proper management, most women with preeclampsia deliver healthy babies.
Symptoms
- High blood pressure, typically 140/90 mmHg or higher
- Protein in urine
- Severe headaches that do not respond to pain relievers
- Changes in vision, including blurred vision or seeing spots
- Upper abdominal pain, usually under the ribs on the right side
- Nausea or vomiting after mid-pregnancy
- Decreased urine output
- Sudden weight gain and swelling, especially in the face and hands
- Shortness of breath
Some women with early preeclampsia have no noticeable symptoms at first. This is why regular prenatal checkups with blood pressure monitoring are so important during pregnancy.

Causes and risk factors
The exact cause of preeclampsia remains unclear, but researchers believe it starts with problems in the placenta. The blood vessels that supply the placenta may not develop properly, leading to poor blood flow. This triggers an inflammatory response that damages blood vessels throughout the body, causing high blood pressure and organ stress.
Risk factors include first pregnancy, history of preeclampsia, carrying twins or triplets, age over 35 or under 20, obesity, diabetes, kidney disease, lupus or other autoimmune conditions, high blood pressure before pregnancy, and family history of preeclampsia. African American women have higher rates of preeclampsia than women of other backgrounds. In vitro fertilization and pregnancies spaced less than 2 years or more than 10 years apart also increase risk.
How it's diagnosed
Preeclampsia is diagnosed through a combination of blood pressure measurements, urine tests, and blood work. Your doctor will check your blood pressure at every prenatal visit and test your urine for protein. Blood tests measure liver enzymes like alanine aminotransferase, which rises when the liver becomes damaged from poor blood flow. Platelet counts and kidney function tests help assess how severely organs are affected.
Rite Aid offers blood testing that includes liver enzyme monitoring to help track organ function during pregnancy. Elevated ALT levels indicate liver cell injury and may signal progression to more severe disease. Your doctor may also order ultrasounds to check fetal growth and amniotic fluid levels. Early detection through regular testing allows for closer monitoring and timely intervention.
Treatment options
- Close monitoring with frequent prenatal visits and blood pressure checks
- Bed rest, either at home or in the hospital, depending on severity
- Blood pressure medications to keep levels in a safer range
- Corticosteroid injections to help the baby's lungs mature faster if early delivery is needed
- Magnesium sulfate through IV to prevent seizures in severe cases
- Delivery of the baby, which is the only cure for preeclampsia
- Reduced salt intake and staying hydrated
- Avoiding activities that raise blood pressure
The timing of delivery depends on how severe the preeclampsia is and how far along the pregnancy is. Mild cases diagnosed near full term may allow for vaginal delivery at 37 weeks. Severe preeclampsia often requires immediate delivery regardless of gestational age to protect maternal health. After delivery, blood pressure usually returns to normal within a few weeks, but some women need continued monitoring.

Frequently asked questions
Preeclampsia is high blood pressure during pregnancy with signs of organ damage, usually to the liver or kidneys. Eclampsia is a more severe condition where preeclampsia progresses to cause seizures. Eclampsia is a medical emergency that can be life-threatening for both mother and baby. Most cases of eclampsia can be prevented with early detection and treatment of preeclampsia.
Yes, preeclampsia can reduce blood flow to the placenta, which means your baby may not get enough oxygen and nutrients. This can lead to slow growth, low birth weight, and preterm birth. Severe preeclampsia may require early delivery before the baby is full term. With close monitoring and proper treatment, many women with preeclampsia deliver healthy babies.
Preeclampsia typically develops after 20 weeks of pregnancy, most commonly in the third trimester. However, it can occur earlier or even develop for the first time during labor or within 48 hours after delivery. This is called postpartum preeclampsia. Women should watch for symptoms for at least 6 weeks after giving birth.
Blood tests measure liver enzymes, kidney function, and platelet counts to see if organs are being damaged. Elevated ALT levels indicate liver cell injury from reduced blood flow and inflammation. Low platelet counts suggest blood clotting problems. These test results help doctors determine how severe the preeclampsia is and whether immediate delivery is necessary.
Having preeclampsia in one pregnancy increases your risk for future pregnancies, but it does not mean you will definitely get it again. About 15 to 25 percent of women who had preeclampsia develop it in a later pregnancy. Your risk is lower if your first case was mild and occurred near your due date. Taking low-dose aspirin starting in early pregnancy may reduce the risk of recurrence.
While no lifestyle change can completely prevent preeclampsia, some measures may reduce risk. Maintaining a healthy weight before pregnancy, eating a balanced diet rich in fruits and vegetables, staying physically active, and managing chronic conditions like diabetes help. Low-dose aspirin starting at 12 weeks may be recommended for women at high risk. Regular prenatal care is the most important prevention tool.
Testing frequency depends on the severity of your condition. Mild preeclampsia may require blood work once or twice a week. Severe preeclampsia often needs daily testing while hospitalized. Your doctor will monitor liver enzymes, kidney function, and platelet counts to watch for signs of worsening. More frequent testing helps guide decisions about delivery timing and treatment intensity.
Blood pressure usually starts to improve within 24 to 48 hours after delivery and returns to normal within 12 weeks. However, some women continue to have high blood pressure for several months and need medication. A small percentage develop chronic hypertension. Women who had preeclampsia should have blood pressure checked at their 6-week postpartum visit and regularly thereafter.
Yes, women who have had preeclampsia have a higher risk of developing heart disease, stroke, and high blood pressure later in life. This increased risk appears even decades after pregnancy. Regular health checkups, maintaining a healthy weight, exercising, and managing blood pressure and cholesterol become even more important. Tell your primary care doctor about your preeclampsia history for better long-term monitoring.
