Strategies to reduce the risk of preeclampsia during pregnancy focus on early identification of high-risk women, pharmacological prophylaxis, lifestyle modifications, and comprehensive antenatal care.

  • Women identified at high risk of developing preeclampsia should be prescribed low-dose aspirin (75–150 mg daily) starting from 12 weeks of gestation until delivery. This is a well-supported intervention to reduce the incidence and severity of preeclampsia ,, .
  • Risk stratification for aspirin prophylaxis includes women with prior hypertensive disease during pregnancy, chronic hypertension, diabetes, chronic kidney disease, autoimmune disorders, or multiple moderate risk factors such as nulliparity, maternal age ≥40 years, BMI ≥35 kg/m2, family history of preeclampsia, pregnancy interval over 10 years, or multifetal pregnancy , .
  • Lifestyle interventions including maintaining a healthy weight through a balanced diet and regular exercise are recommended to lower the risk of preeclampsia , . Observational data suggest that dietary patterns rich in fruits, vegetables (300–400 g daily), whole grains, and unsaturated fats—such as the Mediterranean or DASH diets—may reduce oxidative stress, improve endothelial function, and decrease preeclampsia risk .
  • Physical activity during pregnancy, particularly low-intensity or mind-body exercise modalities (e.g., walking, stationary cycling), has been associated with reduced relative risk of preeclampsia, highlighting the benefit of regular moderate exercise .
  • Nutritional supplements such as calcium may be considered if dietary intake is insufficient, though routine use of supplements like magnesium, selenium, folic acid beyond standard prenatal recommendations, or antioxidants is not generally advised solely for preeclampsia prevention , .
  • Comprehensive antenatal care involving regular blood pressure and proteinuria screening at each visit enables early detection and management of hypertension and preeclampsia , . This includes educating women about warning symptoms warranting immediate medical review, such as severe headache, visual disturbances, epigastric pain, vomiting, breathlessness, and sudden swelling of face or limbs ,.
  • For women with chronic hypertension or identified as high risk, referral to consultant-led care with individualized monitoring and early initiation of antihypertensive medications, when indicated, supports risk reduction , .
  • Innovative approaches such as personalized case management integrating blood pressure monitoring, tailored lifestyle counseling, digital health platforms, and multidisciplinary care can improve blood pressure control, reduce pregnancy complications including preeclampsia, and enhance maternal satisfaction .

In summary, reducing preeclampsia risk relies on early risk assessment, appropriate use of low-dose aspirin, healthy lifestyle measures emphasizing diet and exercise, attentive antenatal surveillance, and individualized multidisciplinary care models.
