Pregnancy with hereditary hypertension is risky and requires pre-pregnancy assessment of the condition and close monitoring during pregnancy. Women with hereditary hypertension may be complicated by pre-eclampsia or eclampsia when they become pregnant, which can affect both the pregnant woman and the fetus. If the blood pressure is too high, it may also affect the function of the placenta, resulting in serious consequences for the fetus in terms of lack of oxygen. The risk in pregnancy is related to the degree of hypertension. Women with hereditary hypertension should be evaluated for pregnancy before becoming pregnant, and their blood pressure status should be strictly monitored after pregnancy. They should also control their weight gain appropriately to avoid excessive weight gain and be hospitalized for evaluation when appropriate. If a patient with hereditary hypertension wants to get pregnant, it is recommended that she seek medical attention in a timely manner and take appropriate treatment under the guidance of her doctor.
