A fundamental task in medicine is the understanding of the causes of diseases. Preeclampsia and eclampsia, an enigmatic and elusive disorder, have been labeled the “disease of theories.” Preeclampsia is one of the “great obstetrical syndromes” in which multiple and sometimes overlapping pathologic processes activate a common pathway composed of endothelial cell activation, intravascular inflammation, and syncytiotrophoblast stress. This article addresses the potential etiologies, or causal explanations, for preeclampsia. The role of uteroplacental ischemia is well established, based upon a solid body of clinical and experimental evidence. A causal role for microorganisms has gained recognition through the realization that periodontal disease and maternal gut dysbiosis are linked to atherosclerosis, thus possibly to a subset of patients with preeclampsia. The recent reports indicating that SARS-CoV-2 infection appears to be causally linked to preeclampsia are reviewed as well as the mechanisms whereby this viral infection can cause this syndrome. Particular etiological factors, such as the breakdown of maternal-fetal immune tolerance, thought to account for the excess of preeclampsia in primipaternity and egg donation—may operate, in part, through uteroplacental ischemia, while another, such as placental aging, may operate largely through syncytiotrophoblast stress. This article also examines the nature of the association between gestational diabetes mellitus and maternal obesity in preeclampsia. The various roles of autoimmunity, fetal diseases, and endocrine disorders are also discussed. A greater understanding of the etiologic factors of preeclampsia is essential to improve treatment and prevention. This article describes the causal risk factors, or etiology, of preeclampsia.
