Hypertensive disorders of pregnancy can return to normal up to 12 weeks after delivery, if the blood pressure is elevated for longer than this line, or if it is considered chronic hypertension. Gestational hypertension can also be delayed into the postpartum period, or it can be detected for the first time in the postpartum period, with preeclampsia or even eclampsia. Newly occurring hypertension in the postpartum period, although not classified as gestational hypertension, still requires attention. When the blood pressure is persistently greater than 150/100 mmHg, it is recommended to be treated with hypotension, and when severe preeclampsia and eclampsia are present, this condition is lowered with the application of magnesium sulfate. Patients with hypertensive disorders still need to take oral antihypertensive drugs before discharge, and blood pressure should be regularly monitored and the dosage of antihypertensive drugs should be adjusted. If blood pressure does not return to normal at 6 weeks postpartum, blood pressure should be rechecked again at 12 weeks postpartum to exclude chronic hypertensive disease, and internal medicine consultation is recommended. Patients whose urine protein is still positive before discharge from the hospital should have regular follow-up urine tests in the outpatient clinic to exclude renal disease. Patients with severe preeclampsia are also at increased risk of developing hypertensive nephropathy and thrombosis in the distant future, and should have their protein and blood pressure reviewed regularly after delivery.
