Key Takeaways
- Women with preeclampsia are at increased risk of recurrence in subsequent pregnancies; recurrence risk is commonly estimated around 20% in clinical literature
- Black women have higher rates of preeclampsia/eclampsia in the U.S., contributing to disparities in severe maternal morbidity
- A meta-analysis reports that women with a BMI ≥30 kg/m2 have increased odds of preeclampsia compared with normal BMI
- In postpartum eclampsia case series, seizures occur after delivery within days to weeks, consistent with postpartum-onset disease patterns
- Postpartum preeclampsia can occur after a previously normotensive pregnancy, so diagnosis relies on postpartum blood pressure and symptom evaluation
- Within 6 hours of delivery, blood pressure can rise and postpartum severe hypertension can emerge, which is why postpartum monitoring is emphasized in clinical guidance
- Overall preeclampsia affects about 3% to 5% of pregnancies globally
- WHO estimates about 500,000 maternal deaths per year globally occur due to pregnancy-related complications overall (context for hypertensive disorders’ burden)
- A Danish population-based study reported that the postpartum period has a higher risk of eclampsia than the background risk, reflecting postpartum-onset cases
- ACOG notes that women with hypertensive disorders of pregnancy should receive a blood pressure evaluation no later than 7 to 10 days postpartum (earlier if symptoms)
- Hydralazine is an evidence-based first-line antihypertensive option for severe hypertension in preeclampsia in WHO guidance
- Preeclampsia is associated with substantially increased risk of future cardiovascular disease, supporting long-term monitoring after delivery
- ~5% of all deliveries in the same cohort study were complicated by postpartum hypertension (including postpartum preeclampsia within that definition)
- 1.8% of postpartum patients were rehospitalized within 30 days for hypertensive disorders of pregnancy in a large US claims analysis (including postpartum preeclampsia-related care)
- 12% of women with preeclampsia report symptoms after discharge that are associated with persistent postpartum hypertension risk (post-discharge symptom burden quantified in a follow-up study)
About 3% to 5% of pregnancies are affected, and postpartum monitoring within 7 to 10 days can save lives.

How We Rate Confidence
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
