Hypertension during pregnancy is a disease specific to pregnancy and must be treated regularly and controlled, otherwise it may lead to intrauterine ischemia and hypoxia or even fetal death. Blood pressure and weight monitoring are routinely performed at every pregnancy checkup and are diagnosed when systolic blood pressure reaches or exceeds 140 mmHg and diastolic blood pressure reaches or exceeds 90 mmHg. If the blood pressure is only high, you can take oral antihypertensive drugs for conservative treatment. It is recommended to eat a low-salt diet, avoid staying up late, and monitor the blood pressure regularly. Pregnant women should pay attention to whether they have edema and have regular maternity checkups to avoid the occurrence of eclampsia due to high blood pressure. Remember not to take antihypertensive drugs on your own, but always take them under the guidance of a doctor to avoid sudden drops in blood pressure leading to syncope. High blood pressure in pregnant women can affect the fetus and in severe cases may cause fetal distress or even fetal death in the womb, so it is especially important to have regular maternity checkups, actively lower the blood pressure and closely monitor the changes in blood pressure and pay attention to the fetal condition in the womb.
