Maternal bulimia nervosa and pregnancy outcomes: a systematic review of obstetric and neonatal risks.

Maternal bulimia nervosa (BN) poses unique challenges during pregnancy. This review aims to synthesize current evidence on the effects of maternal BN on pregnancy, delivery, and neonatal outcomes. A systematic review was conducted of literature published between 2004 and 2024 through PubMed, Cochrane Library, Scopus, and PsycINFO (ProQuest) databases. There was limited and inconsistent evidence amongst the articles showing an increased risk of preeclampsia, gestational diabetes, gestational hypertension, cesarean delivery, LGA, and miscarriage in women with BN. There was mixed evidence of an increased risk of preterm birth in women with BN. No reports found a significant difference in SGA between the two groups. This review highlights critical inconsistencies in the literature showing the effects of maternal BN on pregnancy, delivery, and neonatal outcomes.
