Preeclampsia is the development of elevated blood pressure and protein in the urine after the 20th week of pregnancy. It may be associated with swelling of the face and hands. Preeclampsia occurs in approximately 8% of all pregnancies. Increased risk is associated with first pregnancies, advanced maternal age, African-American heritage, multiple pregnancies, and a past history of diabetes, high blood pressure, or kidney disease.
