Preeclampsia Warning Signs

Preeclampsia is a pregnancy-related hypertensive disorder characterized by high blood pressure and signs of damage to other organ systems, most often the liver and kidneys. It typically occurs after 20 weeks of gestation and can progress rapidly.

Warning Signs and Symptoms

• Severe headaches that do not go away
• Changes in vision: blurring, flashing lights, or sensitivity to light
• Upper abdominal pain, especially under the ribs on the right side
• Nausea or vomiting in the second half of pregnancy
• Swelling of the face or hands
• Sudden weight gain over 1–2 days
• Shortness of breath
• Decreased urine output

Who Is at Risk?

• First pregnancy or first pregnancy with a new partner
• History of preeclampsia in a previous pregnancy
• Chronic hypertension, diabetes, or kidney disease
• Multiple gestation (twins or more)
• Obesity (BMI ≥ 30)
• Age < 18 or > 35

Diagnosis and Monitoring

Preeclampsia is diagnosed by sustained high blood pressure (≥ 140/90 mmHg on two occasions) plus protein in the urine or other organ dysfunction (low platelets, elevated liver enzymes, kidney impairment). Regular prenatal visits are essential for early detection.

When to Seek Emergency Care

If you experience severe headache, visual disturbances, upper abdominal pain, or sudden swelling, contact your obstetric provider immediately or go to the emergency department.
