The effects of eating disorders in pregnancy on mother and baby: a review.

The psychological and physiological interaction between anorexia and the pregnant state has a large intrapartum and postpartum impact on mother and baby. Current research has attempted to discern the short and long term effects of eating disorders (EDs) on pregnancy as well as mother and baby-related sequelae; however little is understood about which management strategies are likely to prove most successful in mitigating these risks. The incidence and effect of low pre-pregnancy body mass index (BMI) on obstetric outcomes, and possible health complications in the future child, has attracted widespread attention. Especially concerning is the fact that it has long been known that the incidence of EDs in women of childbearing age is not only the highest out of all age categories but also is on an increasing trajectory. This paper aims to highlight the recent evidence underpinning the management of pregnant women with EDs in the light of the discussed short and long term effects of the disorders on mother and baby. We shall focus on those women who have a previous diagnosis of an ED prior to being pregnant. Particular attention will be paid to those studies considering anorexia nervosa. We argue for the use of early intervention strategies for the management of pregnant women with eating disorders, and for the use of a multidisciplinary approach in the treatment of these patients with complex problems.
