AbstractSome of the physiological changes that occur in pregnancy manifest in the liver. These alterations might exacerbate or improve some pre-existent liver diseases, while many conditions remain unaffected. Some hepatic manifestations during pregnancy are secondary to disorders unique to pregnancy. Due to improved management of chronic conditions and assisted conception methods, pregnancies in people with cirrhosis or after liver transplantation are increasingly common. With pregnancy also becoming more common in older people and with the rising prevalence of comorbidities, such as obesity, diabetes, and metabolic syndrome, hypertensive disorders of pregnancy and gestational diabetes are increasing in prevalance. Thus, a broad range of specialists might encounter liver abnormalities in pregnancy, necessitating an understanding of how the liver changes during pregnancy and the importance of multi-disciplinary input to mitigate maternal-fetal risks. From a global health perspective, pregnancy also offers a unique opportunity to influence disease management and initiate interventions that might influence the life course of pregnant people and their families. In this Review, we describe the challenges of diagnosing, risk stratifying, and managing liver disease in pregnancy, and explore factors that might affect future maternal health.Copyright © 2025 Elsevier Ltd.
