Anorexia Nervosa and Bulimia Nervosa During Pregnancy

Summary

Anorexia nervosa (AN) and bulimia nervosa (BN) present high-risk situations during pregnancy. These conditions have been associated with poor 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 AN or BN and their offspring. Screening and assessment of women for these eating disorders 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 AN or BN and optimal pregnancy outcomes.
