Headache after pre-eclampsia: what to know

Pre-eclampsia involves high blood pressure and can affect organs. Headache may reflect blood pressure that remains high or rises again after pregnancy. Sleep loss, dehydration, tension, anaemia, or a spinal anaesthetic can also cause head pain, but these explanations should not be assumed before blood pressure is checked. Tell the clinician when the pain started, whether medicine helps, and whether you have flashing lights, blurred vision, upper abdominal pain, nausea, breathlessness, swelling, or reduced urine.

Contact your maternity team or an urgent service for advice and arrange a blood-pressure check. Take prescribed blood-pressure medicine exactly as directed and do not add or stop treatment without guidance. Rest while arranging care, but do not wait for sleep or fluids to settle a significant headache. Bring your medicine list and any home readings. Antenatal follow-up can help plan monitoring; decisions around induction or caesarean birth depend on the pregnancy, blood pressure, symptoms, and clinical findings.

Seek emergency care for a severe or rapidly worsening headache, vision loss or flashing lights, confusion, seizure, weakness, chest pain, severe breathlessness, fainting, or severe pain beneath the ribs. Urgent assessment is also needed when a headache does not improve with the treatment your clinician recommended or returns with raised blood pressure. Do not drive yourself if you feel faint, confused, or unable to see clearly.

Ask what your blood-pressure target is, how often to measure it, which symptoms require emergency care, and how long to continue prescribed medicine. Ask whether you need blood or urine tests, medication review, or follow-up for pre-eclampsia after birth.
