Preeclampsia is a life-threatening hypertensive disorder that occurs only during pregnancy and the postpartum period. According to the Preeclampsia Foundation, it and related disorders — gestational hypertension, HELLP syndrome, and eclampsia — are most often characterized by a rapid rise in blood pressure that can lead to seizure, stroke, multiple organ failure, and even death of the mother and/or baby. If you are pregnant or recently gave birth and notice symptoms such as a sudden rise in blood pressure, this is a reason to contact a healthcare provider promptly rather than wait for a scheduled visit.

Why the "Only in Pregnancy" Timing Matters

Because preeclampsia is tied to pregnancy and the postpartum period, it is not a condition you would track outside that window. That also means symptoms can appear or persist after delivery — the Foundation lists postpartum preeclampsia as its own topic area, so the risk does not automatically end when the baby is born.

The Related Disorders, and How They Differ

Preeclampsia rarely appears alone in the Foundation's framing. It sits within a family of hypertensive disorders of pregnancy:

The Foundation treats these as a spectrum rather than isolated conditions, which is why its health information is organized around the whole group.

What the Warning Signs Point To

The core mechanism the Foundation highlights is a rapid rise in blood pressure. That rise is what can progress to the serious outcomes listed above — seizure, stroke, multiple organ failure, and death of the mother and/or baby. This is why blood pressure monitoring is treated as a practical skill, not just a clinical one: the Foundation publishes guidance on taking your blood pressure and offers a Cuff Kit® for healthcare providers.

When and How to Seek Help

The Foundation's structure suggests a few concrete actions:

• Learn the signs and symptoms so you can recognize a change rather than dismiss it.
• Monitor your blood pressure if you have been advised to, using the Foundation's "Taking Your Blood Pressure" guidance.
• Contact a healthcare provider when something seems wrong. The Foundation maintains an "Ask a Support Question" channel and a "Get Support" section for people who need help navigating next steps.
• Ask about aspirin. The Foundation lists prenatal aspirin among its healthcare provider topics, so whether aspirin is appropriate is a conversation to have with your provider — not a decision to make on your own.

Support and Research Resources

The Preeclampsia Foundation is not only an information source; it also runs programs you can plug into:

• Patient education materials — the Foundation reports distributing 3.5 million patient education materials.
• Provider training — over 115,000 healthcare providers trained.
• Research investment — 2.5 million dollars invested in research, plus a Preeclampsia Registry you can join and a "Participate in Research" pathway.
• Community and events — Promise Walks, volunteer and advocate training, and a video library.
• Long-term follow-up — the Foundation connects preeclampsia to later heart disease and stroke, so the conversation does not end at delivery.

If you want to go deeper on any single piece — the difference between preeclampsia and eclampsia, HELLP syndrome, or postpartum preeclampsia — the Foundation addresses each as a separate topic under its Health Information section.
