Abstract

Healthy women at reproductive age experience a cyclical alteration of gastrointestinal (GI) symptomatology during their menstrual cycle. Additionally, the majority of healthy women also complain of worsening of GI symptoms either during the premenstrual or menstrual phase. Despite conflicting evidence, studies suggest that sex hormones may increase GI transit time during the luteal phase. Similar phenomenon is also observed in women with underlying inflammatory bowel disease (IBD). The mechanism underlying this complex pathophysiology is still not completely understood. However, a possible influence of sex hormones on the brain-gut-microbiota axis is hypothesized. The diagnosis of IBD is associated with a delay in menarche as well as menstrual function irregularities including alterations in cycle length and the duration of flow. There is little data on the effect of menopause on IBD disease activity and conflicting data on the effect of IBD diagnosis on the onset of menopause. The role of contraceptives and hormone replacement therapies on the development or disease activity of IBD has not been yet established. Moreover, IBD patients with concomitant dysmenorrhea report heightened pain during menses. The effect of non-steroidal anti-inflammatory drugs in treating primary dysmenorrhea on the disease course of IBD is unknown. In addition, the effect of IBD medications including immunomodulators and biologics on menstrual function remains unclear. Also, the role of IBD surgery on menstrual irregularities needs to be fully elucidated. Hence, understanding the influence of menstrual function on IBD disease activity and vice versa and the maintenance of normal menstrual function in those patients is important in improving overall reproductive health and fertility and outcome of IBD.
