Severe preeclampsia usually goes down in about a week’s time after delivery, and if the symptoms are more prominent and severe, it can take about six months to recover. The exact time varies from person to person. Pre-eclampsia is a common complication of pregnancy and is associated with abnormally high blood pressure during pregnancy, making it a dangerous obstetric complication. In addition to high blood pressure, severe preeclampsia may be associated with damage to multiple organs in the body, such as renal abnormalities with significant proteinuria, edema, liver metabolic abnormalities, headaches, and funduscopic lesions. In severe preeclampsia, the symptoms are usually relieved after delivery, and the edema is usually eliminated in about one week after delivery. However, if the degree of prenatal organ damage is more serious, the edema will take longer to eliminate, and it may take about half a year after delivery to fully recover. Mothers need to pay more attention to their daily diet, eat more high-protein foods, do not exert themselves, and regularly recheck urine routine, kidney function, liver function, blood pressure and other items.
