[ 1] Gestational hypertension is defined as having a blood pressure greater than 140/90 on two occasions ...
In this case, the diagnosis of gestational hypertension will be updated to be transient hypertension of pregnancy. [13] If the increased blood pressure does not resolve by 12 weeks postpartum, then the diagnosis of gestational hypertension will be updated to be chronic hypertension .
Endothelial dysfunction results in hypertension and many of the other symptoms and complications associated with pre-eclampsia.

[26] Women who have high blood pressure and had complications in their pregnancy have three times the risk of developing cardiovascular disease compared to women with normal blood pressure who ...
Hypertensive encephalopathy ( HE) is general brain dysfunction due to significantly high blood pressure. [ 3] Symptoms may include headache, vomiting, trouble with balance, and confusion. [ 1] Onset is generally sudden. [ 1] Complications can include seizures, posterior reversible encephalopathy syndrome, and bleeding in the back of the eye ...
Preeclampsia is a hypertensive disorder that occurs during the second trimester (after the 20th week of pregnancy) resulting from a poorly perfused placenta. [9] The World Health Organization estimates that preeclampsia and eclampsia are responsible for about 14% of maternal deaths globally (around 50,000 to 75,000 deaths annually). [10]
