Endocrine Factors in Preeclampsia
Endocrinology of Pregnancy, Parturition and Lactation
Endocrine Factors in Preeclampsia
Preeclampsia involves placental and maternal vascular dysfunction with angiogenic and endocrine contributions.
Maternal, placental and fetal integration
Pregnancy changes hormone production, binding, clearance and target-tissue responsiveness. Maternal, placental and fetal tissues contribute different components. Expected laboratory patterns therefore depend on gestational stage and the analytical method, rather than nonpregnant reference values alone.
A distinction that matters
No single hormone or biomarker explains every case or independently establishes severity.
Transitions around birth
Placental delivery rapidly changes steroid exposure, while prolactin-related synthesis and oxytocin-mediated ejection support lactation. These are coordinated but distinct mechanisms. Clinical problems during pregnancy or postpartum require interpretation within their specific maternal and fetal context.
