Does abnormal liver function during pregnancy affect the baby?

Abnormal liver function during pregnancy can affect the fetus. Liver dysfunction may lead to intrauterine growth restriction, as impaired maternal liver function can interfere with the elimination of metabolic byproducts, thereby affecting normal fetal development. If the liver abnormality is caused by hepatitis B virus infection, the fetus may become infected through mother-to-child transmission, resulting in poor development or even severe complications such as liver failure. Drug-induced liver injury may allow toxic substances to cross the placenta and harm fetal health, potentially causing preterm birth, congenital malformations, or stillbirth. Pregnant women with abnormal liver function should seek prompt medical attention to identify the underlying cause and receive appropriate treatment to ensure the health of both mother and baby.
