Late pregnancy hypertension, which refers to the combination of hypertension in pregnant women in late pregnancy, when a systolic blood pressure ≥ 140 mmHg and/or diastolic blood pressure ≥ 90 mmHg is indicated, may be due to changes in hormone levels as well as genetic factors. Patients are advised to seek prompt medical attention and make appropriate dietary modifications, together with medications to lower blood pressure. If the degree of hypertension in pregnant women is mild, the number of blood pressure measurements should be increased according to the specific situation, and blood pressure changes should be closely observed to avoid further development. If you need to take antihypertensive drugs, you should use drugs that have no effect on the fetus according to medical advice. In case of moderate to severe hypertension, it is easy to cause placental abruption, heart failure, cerebral hemorrhage, renal failure and other diseases, leading to premature birth, stillbirth and neonatal asphyxia. Therefore, once the diagnosis of moderate to severe hypertension is confirmed, hospitalization should be promptly and actively managed to prevent eclampsia and complications.
