The time to take medication for gestational hypertension is still mostly chosen in the morning on an empty stomach so that the blood pressure can be controlled consistently throughout the day. For pregnant women in the high-risk group for chronic hypertension, where systolic blood pressure is usually in the range of 140-150 mmHg and diastolic blood pressure is usually in the range of 90-100 mmHg, antihypertensive treatment is mandatory. For those with blood pressure values below these levels, placental perfusion is often impaired, even though antihypertensive therapy is not required. The goal of treatment for severe hypertension is to prevent cerebrovascular events and congestive heart failure without compromising maternal cerebral perfusion and uteroplacental perfusion. The treatment of severe hypertension is aimed at reducing the incidence of maternal-related complications and mortality, rather than preventing pre-eclampsia or placental abruption.
