Preeclampsia

High calcium intake if dietary intake low (dairy, leafy greens, sardines, fortified foods), magnesium-rich foods (pumpkin seeds, spinach, dark chocolate, avocado), adequate protein (some evidence protein restriction worsens preeclampsia), omega-3 rich fish (wild salmon, sardines) 2-3x/week, colorful antioxidant-rich vegetables and fruits, adequate salt (restriction may worsen preeclampsia contrary to old advice), limit processed foods and sugar, adequate hydration, Mediterranean-style diet (associated with lower risk).

Low-dose aspirin if high risk (start 12-16 weeks, proven to reduce preeclampsia by 15-20%), regular prenatal care with blood pressure monitoring, rest and stress reduction (bed rest not proven but avoid excessive activity if symptoms), left lateral position when resting (improves placental blood flow), avoid excessive weight gain, manage chronic conditions (hypertension, diabetes) before pregnancy, preconception optimization for future pregnancies, immediate medical care if symptoms (headache, vision changes, upper abdominal pain, swelling), delivery is only cure (timing depends on severity and gestational age).
