Women who have endometriosis may also be more likely to have migraines, according to a recent Italian study. Researchers from the University of Genoa found that women who had endometriosis were twice as likely to also have migraines. Endometriosis is a condition in which tissue that is normally found only in the womb grows outside the uterus, causing bleeding, inflammation, pain and infertility.
The researchers, who published their results in the December 2004 issue of the journal Human Reproduction, also found that the women with endometriosis reported having migraines at an earlier age than women with migraines but not endometriosis (16 years old versus 22 years old).
More research is needed to understand how the two conditions might be linked.
