Understanding Blood Pressure in Pregnancy

During your pregnancy, you’ll notice that your midwife or doctor checks your blood pressure at every single visit. It’s a quick, simple check, but it’s one of the most important parts of your antenatal care. These regular readings give your care team a clear picture of how your body is adapting to pregnancy and help them catch any potential issues early. For most people, blood pressure stays within a healthy range throughout their pregnancy journey. However, for some, it can rise, which may be a sign of a condition that needs closer monitoring.
