When to see a doctor
See a doctor urgently if:
- If you have a sudden, very severe headache, a headache with blurred vision or floaters, swelling in your face or hands, or if you feel generally unwell with a headache, see a doctor immediately or call your local emergency number.
- If you have any symptoms listed in the emergency section, do not wait.
Book a routine appointment if:
- If you have headaches that are frequent, interfering with your daily life, or if you have a migraine that is different from your usual pattern, make a routine appointment with your midwife or doctor.
Diagnosis
Your doctor will listen to your symptoms, ask about your headache pattern and your pregnancy, and check your blood pressure. They may also do some simple tests to rule out other causes.
Tests that may be done
- Blood pressure check
- Urine test
- Neurological examination (checking your eyes, reflexes, and coordination)
- Sometimes safe imaging tests if needed to rule out other conditions
What to expect at your appointment
The doctor will explain what type of headache you have, talk through safe management options, and review any medicines you are taking. They may also suggest keeping a headache diary to track triggers and symptoms.
Treatment
Treatment for migraine in pregnancy focuses on relief while keeping you and your baby safe. Your healthcare provider will work with you to find the most comfortable approach, starting with non-drug methods and adding medication only when needed and when it is safe.
Self-care at home
- Resting in a dark, quiet room
- Applying a cold or warm compress to your head or neck
- Staying well hydrated
- Eating regular, small meals
- Avoiding known triggers like strong smells or certain foods
Medical treatments
Some pain relief medicines are considered safer in pregnancy than others, but only a healthcare professional can advise what is right for you. Your doctor may also suggest certain vitamins or other treatments that have been shown to help in pregnancy, but no drug names or doses are listed here. Always ask your doctor or pharmacist before taking anything.
When is surgery considered?
Surgery is not used to treat migraine during pregnancy. In very rare cases, a serious underlying cause of headache might require surgical treatment, but this is unrelated to migraine itself.
Living with this condition
Living with migraines while pregnant can be challenging, but many women find that their migraines improve as pregnancy progresses. Planning ahead, using your headache diary, and communicating openly with your doctor can make day-to-day life more manageable.
Lifestyle tips
- Keep a regular sleep schedule
- Practice stress reduction techniques like deep breathing or prenatal yoga
- Take gentle exercise such as walking or swimming, as approved by your doctor
- Limit caffeine to small amounts if you choose to have any
- Try to identify and avoid your personal triggers
Diet and exercise
Eat regular, balanced meals and stay hydrated. Gentle exercise like walking or swimming can help, but check with your doctor before starting any new activity.
Mental health and emotional wellbeing
Living with recurrent pain can increase stress and worry. It is normal to feel anxious or overwhelmed. Talk to your healthcare provider about your feelings; they can offer support or refer you to a mental health professional. If you are having thoughts of harming yourself or your baby, get help immediately.
Prevention
You cannot always prevent migraines, but recognising your triggers and sticking to a routine can reduce the number of attacks.
Vaccines
Vaccines are not used to prevent migraine. However, it's important to stay up-to-date with recommended vaccines during pregnancy for your and your baby's health. Speak to your doctor.
Screening programmes
There is no routine screening test for migraines, but your blood pressure and urine are checked at every pregnancy appointment to spot conditions like pre-eclampsia early.
Complications
If left untreated
- If migraine is not managed, it can cause serious pain and dehydration from nausea and vomiting.
- In rare cases, severe or unusual headaches can be a sign of a serious condition like pre-eclampsia, which needs urgent treatment.
- Untreated severe high blood pressure can affect the placenta and the baby's growth.
Long-term outlook
The outlook is generally good. Most people with migraine find their headaches improve during pregnancy, and for many, the pattern returns to normal after birth. With proper support and a safe plan, you can manage your migraines and look forward to a healthy pregnancy.
