Hypertension in pregnancy can continue into the postpartum period, but it can also occur for the first time in the postpartum period, with preeclampsia or even eclampsia, and the new onset of hypertension after delivery is called postpartum hypertension. Generally, postpartum hypertension does not exceed a maximum of 12 weeks. If it exceeds 12 weeks, it is called chronic hypertension combined with pregnancy. Antihypertensive therapy, such as nimodipine, is recommended when blood pressure is consistently greater than or equal to 150/100 mmhg. When severe pre-eclampsia and eclampsia are present, magnesium sulfate should be used along with the blood pressure lowering.
