01 · Know
What is High Blood Pressure in Pregnancy?
Blood pressure is checked at every antenatal visit because raised blood pressure during pregnancy can develop into more serious conditions, including pre-eclampsia. It can occur in someone with previously normal blood pressure (gestational hypertension) or in someone with pre-existing high blood pressure.
With regular monitoring, most cases are managed successfully throughout pregnancy, though closer follow-up and sometimes medication may be needed to keep blood pressure within a safe range for both the pregnant person and the baby.
02 · Understand
Clinical context
Why blood pressure is checked so often
Regular blood pressure checks at antenatal visits allow small rises to be caught early, before they progress to more serious conditions like pre-eclampsia.
