Disordered eating behaviors (ED), which include conditions such as anorexia nervosa and bulimia, can significantly impact a woman's ability to conceive and her overall experience of pregnancy and the postpartum period. These behaviors often lead to irregular menstrual cycles, which can be an early sign of ED. Because these issues are common among women of childbearing age, they can influence every stage of motherhood, from conception to the postpartum period. ED can affect fertility, increase risks during pregnancy, and contribute to psychological challenges for both the mother and child. ED can be defined as a pattern of eating that deviates from the norms of the individual's sociocultural group and has a significant negative impact on physical, mental, and social health. Common types of ED include anorexia nervosa, characterized by severe food restriction and malnutrition, and bulimia, which involves episodes of overeating followed by compensatory behaviors such as vomiting or excessive exercise. These conditions often begin during adolescence or early adulthood and can persist for up to ten years. They frequently overlap with the fertility window, potentially affecting a woman's ability to conceive. For example, 70 to 90% of women with anorexia nervosa and 75% of those with a history of the condition experience amenorrhea, or the absence of menstruation, which can make it difficult to become pregnant. The impact of ED on pregnancy can be significant. Women with ED are at higher risk for complications such as low birth weight, gestational diabetes, and preterm birth, especially if they are malnourished. The physical and emotional changes of pregnancy can also worsen or trigger ED symptoms, although some women may experience temporary improvement. In the postpartum period, women with ED are more likely to suffer from depression and have difficulties with breastfeeding and bonding with their child. Children of mothers with ED may also face a higher risk of emotional and developmental challenges, including autism spectrum disorders. Because many women with ED do not openly discuss their conditions during pre-pregnancy consultations, doctors must be proactive in identifying these issues through screening tools such as the Scoff test. Early detection is crucial, as effective management of ED can improve fertility outcomes and reduce risks during pregnancy. A multidisciplinary approach, involving healthcare providers such as general practitioners, gynecologists, psychologists, and dietitians, is often necessary to address both the physical and mental health needs of the mother and her child. This comprehensive care can continue beyond pregnancy to support long-term well-being.
