Postpartum headache: common causes and when to worry

How recovery typically progresses

Immediately after

First days

In the first days after delivery, ordinary hormonal shifts, dehydration, and disrupted sleep are common headache contributors, but this is also the window when a spinal headache after an epidural typically starts, usually within 48 to 72 hours, with its telltale worse-sitting-up, better-lying-flat pattern.

Settling in

Early weeks

Through the first couple of postpartum weeks, keep tracking your blood pressure if you have a home cuff or a follow-up appointment, since postpartum preeclampsia most often shows up 7 to 10 days after delivery and can occur even after a completely normal pregnancy.

Longer arc

Beyond six weeks

The diagnostic window for postpartum preeclampsia extends out to 6 weeks after birth, so a new headache around your postpartum checkup still deserves the same attention as one in the first days. Beyond 6 weeks, a persistent or recurring headache pattern is worth its own evaluation rather than continuing to attribute it to early postpartum recovery.

What does the evidence show for postpartum headache?

• Postpartum headaches affect an estimated 30% to 40% of women during the puerperium, and are more common in those with a prior headache history, older maternal age, higher parity, and a shorter second stage of labor. 1
• Benign causes account for more than half of postpartum headache presentations, with primary headache disorders, migraine, tension headache, and cluster headache, described as the most common cause overall. Among headaches that do trace to a specific secondary cause, post-dural puncture headache accounts for about 46% of those cases. 1
• Life-threatening causes of postpartum headache include preeclampsia and eclampsia, a blood clot in the brain's veins, stroke, reversible cerebral vasoconstriction syndrome, and bleeding inside the skull, all of which can produce a headache that looks similar to a benign one in its early stages. 1
• A thunderclap headache, new neurologic symptoms, progressive unusual pain, or elevated blood pressure warrants assessment for a dangerous secondary cause. A reading of 140 systolic or 90 diastolic is elevated; it should not be mislabeled as the severe-range threshold. 1
• Postpartum preeclampsia, one of the more serious specific causes, develops between 48 hours and 6 weeks after delivery and can occur regardless of whether a woman had high blood pressure or preeclampsia during pregnancy itself. 2
• Blood pressure of 140 systolic or 90 diastolic or higher is elevated. A systolic reading of 160 or higher or a diastolic reading of 110 or higher is severe-range: either number matters. Severe readings with a postpartum headache require immediate emergency assessment, without waiting for both numbers to rise. 3
• The recommended approach differs by cause: benign primary headaches are managed with pain relief, nutrition, and sleep, post-dural puncture headaches with rest, hydration, caffeine, and possibly an epidural blood patch, while secondary causes such as preeclampsia need coordinated specialist evaluation rather than home management. 1
• CDC lists a headache that persists or worsens, a sudden severe headache, and vision changes among urgent maternal warning signs. Serious pregnancy-related complications can occur after birth, so a home explanation such as fatigue should not delay medical care. 4

When should I call my provider about postpartum headache?

Get emergency care for a sudden worst-ever headache, new weakness, confusion, seizure, or vision loss. Blood pressure at or above 160 systolic or 110 diastolic with headache also requires emergency assessment; either number matters. Contact the maternity team immediately for a persistent unusual headache, pain with elevated blood pressure, or headache with upper abdominal pain or vision changes. Do not assume an epidural, dehydration, or lack of sleep explains a new severe headache. When in doubt, call your obstetric team the same day. Early input almost always beats waiting, and the on-call line exists exactly for this.
