Abnormal uterine bleeding appears to be yet another symptom of Celiac Disease... For this small research study in 2014, scientists interviewed and compared menstrual history in a group of women with CD versus a group of women with no symptoms of CD. They found that 24% of women with CD had at least one menstrual cycle disorder, whereas only 10% of women without CD reported issues. The women with CD were then placed on a gluten-free diet for 3 months and then re-interviewed for any signs of abnormal bleeding. Out of 12 women who initially reported having cycle disorders, 10 women reported no longer having abnormal bleeding. Although this study did not prove that CD was the cause of cycle disorders, there is a good possibility these are related issues considering the number of women with CD who initially reported abnormal bleeding, and then resolved it with a gluten-free diet. Due to these findings, researchers suggest that health care professionals consider screening patients for CD when they arrive with unexplained uterine bleeding. Reference: Ehsani-Ardakani MJ, et al.
