The specific methods to prevent eclampsia are as follows: 1, diet and nutrition: research suggests that hypertensive diseases are significantly associated with the average intake of sodium and salt in different regions of the population, whether it is hypertensive disease in pregnancy or primary hypertension, the more salt intake, the higher the blood pressure level and prevalence, in the same region, salt-sensitive people consume too much salt, more likely to lead to increased blood pressure, the World Health Organization recommended daily salt Although calcium supplementation cannot reduce the incidence of preeclampsia, it can reduce the incidence of serious complications in patients with preeclampsia, such as eclampsia, severe hypertension, fetal or neonatal death, etc. 2, low-dose aspirin: low-dose aspirin during pregnancy can reduce to a lesser extent the incidence of adverse pregnancy outcomes such as preterm delivery before 34 weeks of preeclampsia, fetal neonatal death, infants less than gestational age, and maternal death, and should be used at low doses before or during early pregnancy; 3, antioxidants: oxidative stress plays an important role in the pathogenesis of preeclampsia eclampsia, and the antioxidant activity in the blood of patients is significantly Pre-eclampsia can be prevented by supplementing with exogenous antioxidants such as vitamin C and vitamin E. 4. Exercise: comparing activity during pregnancy, it was found that women who exercised more had a 78% lower risk of developing pre-eclampsia than women who were inactive or had minimal activity. Physical activity may reduce the incidence of pre-eclampsia eclampsia.
