Background Migraine is a common headache disorder that affects mostly women. In half of these, migraine is menstrually associated, and ranges from completely asymptomatic to frequent pain throughout pregnancy. Methods The aim of the study was to define the pattern (frequency, intensity, analgesics use) of migrainous headaches among women with and without menstural migraine (MM) during pregnancy, and define how hormonally-related factors affect its intensity. Results The analysis was based upon data from 280 women, 18.6% of them having a self-reported MM. Women with MM described a higher headache intensity during early pregnancy and postpartum compared those without MM, but both groups showed improvement during the second half of pregnancy and directly after delivery. Hormonal factors and pre-menstrual syndrome had no effect upon headache frequency, but may affect headache intensity. Conclusions Individual treatment plan is necessary for women with migrainous headaches during pregnancy, especially for those suffering highest symptoms load.
