“Preeclampsia is a serious condition that can happen after the 20th week of pregnancy or after giving birth (called postpartum preeclampsia). Most people who have preeclampsia have dangerously high blood pressure and may have problems with their kidneys or liver. Blood pressure is the force of blood that pushes against the artery walls. An artery is a blood vessel that carries blood away from the heart to other parts of the body. High blood pressure (also called hypertension) can stress the heart and cause problems during pregnancy.”
