[Pregnancy and breastfeeding in Crohn's disease]

Inflammatory bowel disease (IBD) is often diagnosed in young adults. Starting a family is an important step in life and can be further complicated by Crohn's disease. Therefore, family planning should be discussed with every patient early in the disease course. Counseling about the importance of disease remission and the safety of IBD medication during pregnancy can ameliorate the pregnancy outcome. Active disease during pregnancy can lead to adverse pregnancy outcomes such as preterm birth and low birthweight. To maintain disease remission most therapies should be continued despite the wish to have children. Only a few substances currently used to treat Crohn's disease are contraindicated during pregnancy and should be stopped before conception. This includes Januskinase (JAK)-inhibitors and Methotrexate. Biologics including anti-TNF-therapy, anti-IL-12/anti-IL-23 and anti-integrin therapies should be continued during pregnancy.
