Endometriosis and migraine

Endometriosis is more common in women who have migraine headaches, and migraine is more common in women with endometriosis.

An Italian study found that 1/3 of women who had endometriosis also suffered from migraine headaches. About 5% of women of reproductive age have endometriosis. Another study found that of women with pelvic pain, 2/3 experience migraine – about three times the rate of the general population. Not all the women with pelvic pain had biopsy-proven endometriosis.

Several studies have now also shown an increased incidence of endometriosis in migraine sufferers, and this is felt to be most likely due to common genetic factors. Migraine attacks were more frequent in women with endometriosis than in women with migraine and no endometriosis, and migraines began at a younger age.
