Pregnancy toxemia is a condition in which a pregnant woman experiences high blood pressure, proteinuria, and other symptoms that can be dangerous to both the mother and unborn child. Synonyms for this condition include preeclampsia, gestational hypertension, and toxemia of pregnancy. Preeclampsia is characterized by high blood pressure and protein in urine, while gestational hypertension is high blood pressure only. Toxemia of pregnancy is often used interchangeably with preeclampsia, but can also refer to a more severe form of the condition. Any of these terms should be taken seriously if experienced during pregnancy and medical attention should be sought immediately to ensure the safety of both mother and child.
