Causes
The exact cause of preeclampsia has not been identified. Numerous theories of potential causes exist, including genetic, dietary, vascular (blood vessel), and autoimmune factors. None of the theories have yet been proven.
Preeclampsia occurs in approximately 8% of all pregnancies. Increased risk is associated with first pregnancies, advanced maternal age, African-American women, multiple pregnancies, and women with a past history of diabetes, hypertension, or kidney disease.
