Headaches After Birth
Most postnatal headaches come from sleep loss, dehydration, caffeine changes, hormone shifts or neck tension from feeding posture. Two patterns need urgent attention: a severe headache with visual changes or swelling, and a headache that is much worse sitting up after an epidural or spinal.
Why headaches are so common after birth
Headache is one of the most frequently reported symptoms in the first postnatal weeks, and in the large majority of cases the cause is mundane. Several ordinary triggers arrive at once:
- Sleep deprivation, which is the biggest single contributor.
- Dehydration, particularly if you are breastfeeding, which raises fluid needs substantially and is easy to under-meet when you cannot get to a glass of water.
- Irregular eating and the blood sugar swings that follow.
- Caffeine changes. Either a sharp increase, or a withdrawal headache if you cut back suddenly.
- Hormonal shift. Oestrogen falls steeply after birth, and people prone to hormonal migraine often notice a flare.
- Neck and shoulder tension from hours spent looking down at a feeding baby, which produces a classic tension headache spreading from the base of the skull.
- Anaemia, if you lost a significant amount of blood, which commonly presents as headache with fatigue and breathlessness.
The two patterns that need urgent attention
1. Pre-eclampsia after birth
Pre-eclampsia does not always end with delivery. It can appear or worsen after birth, usually in the first few days but sometimes weeks later, and a headache is one of its cardinal symptoms.
Seek medical help immediately — contact your maternity unit or go to hospital — if a headache comes with any of:
- Vision changes: blurring, flashing lights, spots or temporary loss of vision.
- Sudden swelling of the face, hands or feet.
- Pain just below the ribs, typically on the right side.
- Vomiting.
- Feeling generally very unwell.
The headache of pre-eclampsia is typically severe, persistent, and not relieved by ordinary pain relief. Do not wait for a routine appointment; this is one of the main reasons maternity units expect calls after discharge.
2. Headache after an epidural or spinal
If you had an epidural or a spinal anaesthetic, a post-dural puncture headache is a recognised complication. Its signature is postural: it is markedly worse when you sit or stand and substantially better when you lie flat. It is often felt at the front of the head or behind the eyes and may come with neck stiffness, nausea, or sensitivity to light and sound.
It typically begins within a day or two of the procedure. Contact your maternity unit or the anaesthetic team — this is treatable, and effective treatment exists, so it should not simply be endured for weeks.
Other reasons to get checked promptly
Contact a doctor or your maternity team if you have:
- A headache that comes on suddenly and severely, reaching maximum intensity within seconds or minutes.
- Headache with a fever, a stiff neck, or a rash.
- Headache with confusion, weakness, numbness, difficulty speaking, or a seizure. Call 999.
- Headache with high blood pressure readings if you are monitoring at home.
- A headache that is getting steadily worse over days rather than better.
- Headache that wakes you from sleep or is worse when you cough or bend forward.
Managing an ordinary postnatal headache
- Water first. Keep a bottle wherever you feed. Dehydration is the most commonly missed cause.
- Eat something. Regular meals and easy snacks within reach.
- Fix the feeding posture. Bring the baby up to you with cushions and sit back against a support rather than curling over. This alone resolves a lot of tension headaches.
- Sleep when you can. Unhelpful as advice, but genuinely the strongest lever. Hand over one feed if there is anyone to hand it to.
- Keep caffeine steady rather than swinging up or down.
- Heat on the neck and shoulders, and gentle movement.
- Pain relief. Ask a pharmacist what is suitable for you, telling them if you are breastfeeding. They will point you to appropriate options.
- Get outside. Daylight and fresh air help more than they sound like they should.
If headaches persist
See a GP if headaches are frequent beyond the first few weeks, are not responding to simple measures, or are interfering with looking after yourself or your baby. Worth asking about specifically: a blood pressure check, iron levels if you lost a lot of blood, and thyroid function, since thyroid problems after birth are common and can present vaguely. Frequent use of painkillers can itself cause medication-overuse headache, which is another reason not to run on them for weeks without review.
Migraine after birth
People with a history of migraine often notice a change in pattern after birth. Migraine frequently improves during pregnancy, particularly in the second and third trimesters, and the steep fall in oestrogen after delivery commonly triggers a flare in the first week or two.
If you had migraine before pregnancy and recognise the same pattern — a one-sided throbbing headache, nausea, sensitivity to light and sound, sometimes preceded by visual aura — it is likely to be the same condition rather than something new. Discuss treatment with a clinician who knows whether you are breastfeeding, since suitable options exist but not all usual treatments are appropriate.
New aura, or aura for the first time, should be assessed rather than assumed.
Caffeine, and the trap in it
Two opposite mistakes are common. Some people cut caffeine sharply after birth, having reduced it during pregnancy, and get a withdrawal headache. Others increase it steeply to cope with broken sleep, which disrupts what sleep they can get and can produce rebound headaches. Steady and moderate beats either.
Keeping a simple record
If headaches are frequent, a few lines a day is genuinely useful at an appointment: when it started, how long it lasted, what you had eaten and drunk, how much sleep you had, whether it was worse sitting or lying, and anything that helped. The postural question in particular — better lying flat, or not — is the single most useful piece of information you can bring if you had an epidural or spinal.
