Headaches during pregnancy

Most headaches in pregnancy are mild and primary headaches (the headache pain which happens by itself). It is not a sign or symptom of an underlying disorder or a complication during the pregnancy. 

Primary headaches include:

  • Tension headache 
  • Migraine attack
  • Cluster headache

About 26 % of headaches during pregnancy are “tension headaches”. The female should tell her doctor if she has chronic headaches or migraines in pregnancy or if she has a history of migraines. 

Some females with a history of migraines get just a few migraine attacks during pregnancy. Migraines have also been linked to complications that happen later in the pregnancy or after childbirth. 

On the other hand, secondary headaches are quite different from primary headaches. Secondary headaches are caused due to a complication in the pregnancy, like high blood pressure and are often a sign of an underlying complication, condition or disorder in pregnancy.
