Anorexia Nervosa, Bulimia Nervosa, and Binge-Eating Disorder During Pregnancy

Abstract

Anorexia nervosa (AN), bulimia nervosa (BN), and binge-eating disorder (BED) present high-risk situations during pregnancy. These conditions have been associated with inadequate or inconsistent energy and nutrient intakes, notably total energy; folate; vitamins B6, B12, and A; calcium; iron; and zinc. Electrolyte imbalances are also of concern. Inadequate or excessive weight gain, spontaneous abortion, intrauterine growth restriction, preterm delivery, and low birth weight, among other adverse outcomes, have been reported in pregnant women with eating disorders and their offspring. Screening and assessment of women for AN, BN, or BED during prenatal clinic visits is recommended. An interdisciplinary approach to care during pregnancy, the postpartum period, and beyond is critical to the successful management of eating disorders and optimal pregnancy outcomes.
