Preeclampsia: Symptoms, Causes, Risk Factors, and When to Seek Emergency Care

Pregnancy is an exciting journey, but it also comes with health conditions that require careful attention. One of the most serious complications is preeclampsia, a condition characterized by high blood pressure and signs of organ damage, usually after the 20th week of pregnancy.

Recognizing the symptoms early and receiving prompt medical care can greatly reduce risks for both the mother and baby.

What Is Preeclampsia?

Preeclampsia is a pregnancy-related disorder that causes high blood pressure and may affect organs such as the kidneys, liver, brain, and placenta.

Although many women with preeclampsia deliver healthy babies, untreated cases can become life-threatening.

Common Symptoms of Preeclampsia

Symptoms may include:

  • High blood pressure
  • Severe headaches
  • Changes in vision, such as blurred vision or seeing flashing lights
  • Swelling of the face or hands
  • Sudden weight gain
  • Pain in the upper right abdomen
  • Nausea or vomiting after mid-pregnancy
  • Shortness of breath
  • Reduced urine output

Some women experience no noticeable symptoms, making regular prenatal checkups extremely important.

What Causes Preeclampsia?

The exact cause remains unknown, but researchers believe it is related to abnormal development of blood vessels in the placenta during early pregnancy.

Several factors may contribute, including:

  • Problems with blood flow to the placenta
  • Immune system changes
  • Genetic factors
  • Blood vessel disorders

Risk Factors

The risk is higher if you:

  • Are pregnant for the first time
  • Had preeclampsia in a previous pregnancy
  • Are carrying twins or multiples
  • Have chronic high blood pressure
  • Have diabetes
  • Have kidney disease
  • Have obesity
  • Are over age 35

How Is It Diagnosed?

Doctors diagnose preeclampsia using:

  • Blood pressure measurements
  • Urine tests to check for protein
  • Blood tests
  • Ultrasound scans to monitor the baby’s growth
  • Fetal heart monitoring when needed

Treatment

Treatment depends on how severe the condition is and how far along the pregnancy is.

Options may include:

  • Frequent monitoring
  • Blood pressure medications
  • Magnesium sulfate to prevent seizures in severe cases
  • Early delivery if the condition threatens the mother or baby

The only complete cure is delivery of the baby and placenta.

Possible Complications

Without treatment, preeclampsia can lead to:

  • Eclampsia (seizures)
  • Stroke
  • Liver or kidney damage
  • Placental abruption
  • Premature birth
  • Poor fetal growth

Can It Be Prevented?

While it cannot always be prevented, healthy habits may lower the risk:

  • Attend all prenatal appointments.
  • Follow your healthcare provider’s advice.
  • Maintain a healthy weight before pregnancy.
  • Manage chronic conditions such as diabetes or high blood pressure.
  • Take low-dose aspirin if recommended by your doctor.

When Should You Seek Emergency Care?

Seek immediate medical attention if you experience:

  • Severe headache that doesn’t go away
  • Vision changes
  • Severe abdominal pain
  • Difficulty breathing
  • Heavy swelling that develops suddenly
  • Decreased baby movement

Final Thoughts

Preeclampsia is a serious pregnancy complication, but early diagnosis and proper medical care can significantly improve outcomes. Never ignore warning signs, and contact your healthcare provider if you have any concerns during pregnancy.
