Your Blood Pressure During Pregnancy: Why It Matters

Blood pressure is checked often in pregnancy because it can offer important information about maternal health. The number alone is not the whole story, but changes in blood pressure can help healthcare professionals decide when closer monitoring is needed.

What is it?

Blood pressure describes the force of blood against the artery walls as the heart pumps and rests. During pregnancy, routine checks help screen for high blood pressure and conditions such as pre-eclampsia.

Why it matters

Some blood-pressure conditions in pregnancy can affect the mother, placenta and baby. Readings need to be interpreted in context: gestational age, previous readings, symptoms, urine tests, blood tests and medical history can all matter.

Warning signs

• A severe headache or a headache that does not go away
• Vision changes
• Pain in the upper abdomen or shoulder
• Shortness of breath or chest symptoms
• Sudden swelling of the face or hands
• Feeling very unwell
• A seizure

When to seek urgent medical care

What to tell your healthcare professional

• Your recent blood-pressure readings and when they were taken
• Whether the reading was taken at home, clinic or pharmacy
• Any symptoms you have noticed
• Any history of high blood pressure, kidney disease, diabetes or pre-eclampsia
• Any medications or supplements you are taking

Questions you may want to ask

• What does my blood pressure mean in my situation?
• Should I monitor at home, and how should I record readings?
• What symptoms should make me contact you urgently?
• Do I need urine or blood tests alongside blood-pressure checks?

Key takeaway

A blood-pressure reading is information, not a self-diagnosis. Keep records, ask questions and report concerning symptoms early.
