We did not find a significant association between severity of endometriosis and self-reported coeliac disease, neither did we find an association with self-reported lactose intolerance. The endometriosis PGS was not associated with defaecation pattern regularity ( P FDR = 1.00), though it did associate (nominally significant) with some of the gastrointestinal symptoms, i.e. abdominal pain (OR = 1.22, 95% CI = 1.01–1.47, p = 0.04, P FDR = 0.55) and pain during food intake (OR = 2.60, 95% CI = 1.28–5.29, p = 0.01, P FDR = 0.09).
