How do I know if I have Pre-eclampsia?

Pre-eclampsia is a pregnancy complication characterized by high blood pressure and signs of damage to other organ systems, most often the liver and kidneys. You should suspect pre-eclampsia if you experience a sudden onset of high blood pressure, severe headaches, or swelling, and you must contact your healthcare provider immediately to confirm the diagnosis through blood and urine testing.

What are the early signs and symptoms of pre-eclampsia?

Pre-eclampsia often develops after the 20th week of pregnancy. Early symptoms can be subtle and easily mistaken for normal pregnancy discomforts. The most critical indicator is a blood pressure reading of 140/90 mmHg or higher on two occasions at least four hours apart. Other early signs include persistent, severe headaches that do not respond to acetaminophen, sudden swelling (edema) in the face, hands, or feet, and unexpected, rapid weight gain—often more than 2-3 pounds in a week—due to fluid retention.

How can I perform a self-assessment for pre-eclampsia?

While you cannot diagnose pre-eclampsia at home, you can monitor for patterns that warrant a clinical visit. Keep a log of your blood pressure if you have a home monitor, and pay close attention to your body’s signals. Distinguishing between normal pregnancy variation and pre-eclampsia symptoms is vital: normal swelling usually occurs gradually in the feet, whereas pre-eclampsia often presents with sudden, significant puffiness in the face and hands. If you feel "off" or notice vision changes—such as blurriness, flashing lights, or light sensitivity—do not wait for your next scheduled appointment.

What tests should I ask my doctor for?

If you suspect you have pre-eclampsia, your physician should perform a comprehensive evaluation. You can advocate for these specific assessments:

• Blood pressure monitoring: Frequent checks to confirm a sustained elevation.


• Urinalysis: To check for proteinuria (excess protein in the urine), a hallmark sign of kidney stress.


• Blood tests: To check liver enzyme levels, platelet counts, and kidney function (creatinine levels).


• Fetal monitoring: An ultrasound or non-stress test to ensure the baby is growing well and receiving adequate oxygen.

When should I seek urgent medical evaluation?

Certain "red flag" symptoms indicate that pre-eclampsia may be progressing to a more severe state, such as eclampsia or HELLP syndrome. You must seek emergency care if you experience:

1. Severe, persistent pain in the upper right abdomen (under the ribs).


2. Sudden, severe vision loss or significant visual disturbances.


3. Difficulty breathing or shortness of breath.


4. Confusion, extreme agitation, or seizures.

How do I advocate for myself if my concerns are dismissed?

If you feel your symptoms are being dismissed as "normal pregnancy," trust your intuition. You are the expert on your own body. Use clear, direct language: "I am concerned that my symptoms are not typical for this stage of my pregnancy, and I would like a blood pressure check and a urine protein test to rule out pre-eclampsia." If you are still not heard, do not hesitate to seek a second opinion or go to the labor and delivery triage unit at your hospital. Within the DiseaseMaps community, 80 people with pre-eclampsia have shared their experiences, and many emphasize that early detection saved their lives and their babies' lives.
