Exploring the Relationship Between Eating Disorders and Reproductive Health, with a Focus on Fertility, Obstetric, and Fetal Outcomes: A Narrative Review.

PURPOSE OF REVIEW: Eating disorders can profoundly impact reproductive health in females, spanning from the onset of puberty through menopause. The impact is due to a variety of factors, including nutritional status, body fat percentage, and hormone regulation. Notably, fertility and pregnancy are particularly vulnerable to undernutrition and disordered eating. This narrative review provides a comprehensive summary and discussion of available literature from the past 5 years exploring the impact of eating disorders on fertility, obstetric outcomes, and fetal outcomes.

RECENT FINDINGS: Current literature demonstrates that EDs can have a negative impact on fertility, obstetric outcomes, and fetal outcomes. Primary research and systematic reviews support associations including increased use of assisted reproductive treatment for infertility, anemia and hyperemesis during pregnancy, and preterm delivery. Associated fetal outcomes include infant low birth weight, small for gestational age, and microcephaly. EDs, when unrecognized and left untreated, can negatively impact fertility, obstetric outcomes, and fetal outcomes. It is important for providers to be aware of these associations and implement screening to identify at-risk patients, as appropriate treatment can improve reproductive outcomes.
