What is one of the risk factors for developing preeclampsia?

A personal history of hypertension is indeed a significant risk factor for developing preeclampsia during pregnancy. Women who have had high blood pressure issues prior to becoming pregnant or have a history of chronic hypertension are predisposed to experience similar complications in subsequent pregnancies. This history suggests that their cardiovascular system may respond poorly to the physiological changes and additional demands of pregnancy, thereby increasing the likelihood of developing elevated blood pressure and related conditions such as preeclampsia.

In contrast, risk factors like low body mass index, multiparity, and age under 25 do not directly correlate with an increased risk for preeclampsia. Low body mass index is often associated with a lower risk, while multiparity can be both a risk and protective factor, depending on the individual. Younger maternal age typically implies a reduced risk for preeclampsia when compared to older ages, where risks tend to increase. Thus, having a personal history of hypertension stands out as a clear and relevant risk factor for this condition.
