Preeclampsia is a disorder of pregnancy characterized by high blood pressure of the mother and often a significant amount of protein in the urine. When it arises, the condition begins after about twenty weeks of pregnancy. In severe cases of the disease there may be red blood cell breakdown, a low blood platelet count, impaired liver function, kidney dysfunction, swelling, shortness of breath due to fluid in the lungs, or visual disturbances. Preeclampsia increases the risk of undesirable outcomes for both the mother and the fetus. If left untreated, it may result in seizures at which point it is known as eclampsia.
