Hypertensive women are at relatively high risk of pregnancy and childbirth. Normal women may develop gestational hypertension during pregnancy, and high blood pressure can lead to pre-eclampsia, causing bleeding and miscarriage, threatening the health of the fetus and the pregnant woman, but whether a pregnant woman with hypertension can carry a child depends on the specific level of hypertension, clinical symptoms, underlying diseases and complications. If the normal blood pressure of pregnant women with hypertension is controlled within the normal range, the patient has no obvious clinical symptoms and no other underlying diseases, the relative risk of having a child is small and the prognosis is good. If the blood pressure of pregnant women with hypertension is poorly controlled, and the usual blood pressure is above 160 mmHg and 100 mmHg, and accompanied by headache, dizziness, nausea, vomiting, urine protein, etc., such pregnant women have a greater risk of having a child and a poor prognosis In addition, they are prone to hypertensive crisis, hypertensive encephalopathy, eclampsia and other complications of cardiovascular and cerebrovascular diseases.
