Women with migraine have a higher chance of also having endometriosis. A study by Dr. Gretchen Tietjen and her colleagues published in the latest issue of journal Headache looked at 171 women with migraine and 104 controls. Endometriosis was reported more commonly in migraineurs than in controls (22% vs 9.6%). Frequency of chronic headache was higher in migraineurs with endometriosis ompared to without it and headache-related disability scores were also higher in the endometriosis group. Depression, anxiety, irritable bowel syndrome, fibromyalgia, chronic fatigue syndrome, and interstitial cystitis were more common in migraine with endometriosis group than in controls. Anxiety, interstitial cystitis and chronic fatigue syndrome were more common in migraine with endometriosis group, than in the patients with migraine without endometriosis.
