Liver disease in pregnancy.

The liver is one of the many organs affected by the physiologic and hormonal changes that occur during pregnancy. Hepatic disorders diagnosed before pregnancy may be unaffected or exacerbated by the pregnant state. Liver disorders that are specific to pregnancy, including hyperemesis gravidarum, intrahepatic cholestasis of pregnancy, acute fatty liver of pregnancy, preeclampsia/ eclampsia, HELLP, and hepatic rupture, may have a profound impact on the morbidity and mortality rates of mother and fetus. Although an unequivocal diagnosis is often difficult to make, it should be attempted in a timely manner so that optimal treatment can be determined. After the diagnosis is made, maximizing the health of the mother and fetus determines future management.
