Each pregnancy is unique, and all pregnant people deserve the best chance of three healthy trimesters and a safe, fulfilling delivery. Unfortunately, a serious pregnancy complication called preeclampsia threatens this hope for many families. Preeclampsia causes dangerously high blood pressure and can damage the kidneys or liver. When it goes undetected or untreated, it can lead to preterm birth (baby being born before 37 weeks of pregnancy), serious health complications and, in the worst cases, the death of a mother or baby.
