Pregnancy in Patients with Inflammatory Bowel Disease: A Narrative Review

Background: The incidence of inflammatory bowel diseases (IBDs) peaks in the fertile age of both women and men. There is a significant lack of knowledge regarding disease-specific aspects of guiding IBD patients through conception, pregnancy, and delivery in clinical routine. Summary: Patients with IBD often remain voluntarily childless, primarily due to a lack of knowledge. Fertility is generally unaffected in IBD patients, except in those with high disease activity or who have undergone specific abdominal surgeries that may lead to changes in the abdominal cavity, such as inflammatory or postoperative adhesions. Immunosuppressive and immunomodulatory medications are generally considered safe during pregnancy and should be continued to reduce the likelihood of relapses. If flares occur, close monitoring of the mother and the fetus is mandatory, and therapeutic options (conservative, interventional, surgical) have to be weighed thoroughly. Despite advances in treatment, IBD patients remain at increased risk of preterm labor, small-for-gestational-age newborns and are at risk of C-sections, although the current literature suggests vaginal delivery is possible for most patients. C-sections are recommended in patients with active perianal disease. Key Messages: Patients with IBD wishing to conceive should receive comprehensive preconception counseling about pregnancy-specific aspects of IBD management from an interdisciplinary team of specialists, including IBD gastroenterologists, obstetricians, and colorectal surgeons.
