Dietary practices of women with Endometriosis: a cross-sectional survey
Abstract Background: Endometriosis causes deleterious effects on the lives of sufferers across multiple domains impacting quality of life. Commonly utilised pharmaceutical interventions offer sub-optimal efficacy in addition to potentially intolerable side effects for many women. There is some evidence for dietary therapies reducing endometriosis symptoms but little data on dietary preferences / strategies used, and their impact, in a community setting. Methods: A cross-sectional online survey was conducted between October and December 2017 to investigate the self-management strategies employed by women with endometriosis. Participants were aged 18-45 years, living in Australia and had a surgically confirmed diagnosis of endometriosis. Results: Four hundred and eighty-four responses were included for analysis, with 76% of women reporting the use of general self-management strategies within the last six months. Of these, 44% of respondents reported using dietary strategies for symptom management. Reducing or eliminating gluten, reducing or eliminating dairy and the low FODMAP diet were the most commonly reported dietary strategies utilised. Respondents reported a 6.4/10 effectiveness score for reduction in pelvic pain with dietary changes, with no difference in pain reduction between the various diets used. Further, women self-reported significant improvements in co-morbidities such as gastrointestinal disturbance (39%), nausea and vomiting (15%) and fatigue (15%).Conclusions: Dietary modifications are a very common self-management strategy employed by people with endometriosis, with the greatest benefit reported on gastrointestinal symptoms. Reducing or eliminating gluten, dairy or FODMAPs, or a combination of these, were the most common strategies. No single diet appeared to provide greater self-reported benefits than others.
