Anorexia nervosa is a potentially severe, chronic, and relapsing mental disorder that is more common in women and girls during the reproductive years (usually defined as those aged 12–51 years). It is associated with suicide and mortality linked with the physical consequences of starvation. Although anorexia nervosa is a disorder of low prevalence, and even lower prevalence in pregnancy, it is associated with substantial risks for the mother and infant when under-recognised and undermanaged. Despite the complexity and risk of managing anorexia nervosa in pregnancy, few studies are available to guide care. We conducted a systematic review, identifying only eight studies that addressed the management of anorexia nervosa in pregnancy. These studies were case studies or case reports examining narrow aspects of management. Subsequently, we conducted a state-of-the-art review across research in relevant disciplines and areas of expertise for managing anorexia nervosa in pregnancy and synthesised the findings into recommendations and principles for multidisciplinary management of anorexia nervosa in pregnancy. These recommendations included a focus on the specialist mental health, obstetric, medical, and nutritional care required to ensure optimal outcomes for women and their infants. Despite the complexity and risks, a gap exists in the comprehensive guidelines and recommendations for managing anorexia nervosa in pregnancy. This Review provides multidisciplinary recommendations for clinical care in this area. Managing anorexia nervosa in pregnancy is an area of clinical care that requires a multidisciplinary approach and includes those experienced in managing high-risk pregnancies.

神经性厌食症是一种潜在的严重、慢性和复发性精神障碍，在育龄期的女性和女孩（通常定义为 12-51 岁）中更为常见。它与自杀和与饥饿的身体后果有关的死亡率有关。虽然神经性厌食症是一种低患病率的疾病，甚至在怀孕期间患病率更低，但如果认识不足和管理不善，它会给母亲和婴儿带来重大风险。尽管管理妊娠期神经性厌食症的复杂性和风险，但很少有研究可用于指导护理。我们进行了系统评价，仅确定了八项研究处理妊娠期神经性厌食症的管理。这些研究是案例研究或案例报告，检查管理的狭隘方面。随后，我们对管理妊娠期神经性厌食症的相关学科和专业领域的研究进行了最先进的审查，并将研究结果综合成妊娠期神经性厌食症多学科管理的建议和原则。这些建议包括重点关注确保妇女及其婴儿获得最佳结果所需的专业心理健康、产科、医疗和营养护理。尽管存在复杂性和风险，但在管理妊娠期神经性厌食症的综合指南和建议中仍存在差距。本综述为该领域的临床护理提供了多学科建议。
