After miscarriage with preeclampsia, you should take bed rest, avoid sexual intercourse, have a reasonable diet, and pay attention to the vaginal bleeding. 1. Bed rest: pregnant women with preeclampsia should avoid strenuous exercise and try to rest in bed. Pregnant women should elevate their lower limbs during bed rest to avoid the formation of blood clots in the lower limbs. 2. Avoid sex: sexual stimulation may cause uterine contractions, aggravating the symptoms of miscarriage, so women with preeclampsia should avoid sex, and should pay attention to keep the vulva clean and dry to prevent infection. 3. Reasonable diet: Increased abdominal pressure can induce miscarriage, so pregnant women with preeclampsia should pay attention to a reasonable diet to avoid diarrhea or constipation. 4. Pay attention to vaginal bleeding: when the premonitory miscarriage develops into an inevitable miscarriage, it will be manifested by heavy vaginal bleeding, which may cause shock in severe cases. Therefore, pregnant women with preeclampsia should pay attention to the amount of vaginal bleeding, and consult the doctor in time when the bleeding is heavy, so as to avoid hemorrhagic shock. Pregnant women with preeclampsia who have vaginal bleeding accompanied by a bad odor may have an infection and should seek medical attention promptly. Pregnant women with preeclamptic miscarriage should seek prompt medical attention, undergo fertility preservation treatment under the guidance of a doctor, and monitor their own health condition at all times.
