Study on the regularity of blood pressure changes in pregnant women and its influencing factors

Blood pressure in pregnant women typically decreases in early pregnancy, then gradually rises during mid- and late pregnancy. The duration of HNBP is generally short, with most cases resolving on their own. Pre-pregnancy hypertension, BMI, cortisol levels, and occupational type are risk factors for gestational hypertension. However, normal blood pressure variability during pregnancy has little effect on maternal and neonatal outcomes.
