Eating disorders (EDs) impact physical, emotional, and social health. The perinatal period, including pregnancy and the first postpartum year, is high-risk for EDs due to hormonal and psychosocial changes. However, symptom remission can also occur, influenced by hormonal factors, social support, and maternal motivations. This case study examines a woman diagnosed with Bulimia Nervosa (BN) who experienced remission during pregnancy. Semi-structured interviews identified protective factors: motivation for fetal well-being, self-care, and social support. The findings indicate that prenatal care and social support are crucial in reducing BN symptoms during pregnancy. A multidisciplinary approach involving medical, psychological, and nutritional support is essential for managing EDs in pregnant women. These results underscore the importance of targeted preventive and therapeutic strategies to improve maternal and fetal health.
