What causes headaches during pregnancy?

Dr. Dawn Marcus
Neurologist

Although most headaches during pregnancy are not caused by serious health problems, you should talk to your doctor whenever you develop new headaches, notice a change in your headache pattern or symptoms, or note new health problems. Some medical conditions that may cause headaches during pregnancy include:

  • Infection
  • Preeclampsia/eclampsia (high blood pressure, edema and other complications of pregnancy)
  • Brain vascular diseases (such as strokes, aneurysms, dissections and vascular malformations)
  • Brain tumors (especially pituitary adenomas and meningiomas)
  • Increased intracranial pressure not related to tumors (called pseudotumor or benign intracranial hypertension)

Headaches are quite common during the first trimester. When you become pregnant the body manufactures extra blood to circulate through the placenta to feed your baby. This increase in blood flow can sometimes trigger what we call pregnancy headaches. Hormone levels also fluctuate greatly during pregnancy and hormones have long been associated with migraines. For some of you that have migraines you may find they actually get better during pregnancy while unfortunately the rest of you may find they get much worse. Allergy sufferers will not be immune to allergy headaches while pregnant and people under lots of stress who experience tension headaches will also not be immune to these just because they are pregnant. Any persistent headaches should always be discussed with your midwife or ob/gyn.

With links between hormone levels and migraines, it's no surprise that you may experience terrible headaches during pregnancy. (Or the opposite—many women enjoy a remission from migraines, especially during the second and third trimesters.) If you do, be aggressive about looking for triggers (like caffeine and chocolate), so you can eliminate those stimuli. If headaches persist, seek help from an expert in headaches to reduce the severity and frequency of these very stressful events. Medication may be warranted—there are several options that are safe in pregnancy.
