Liver disease in pregnancy, whether preexisting before pregnancy or pregnancy-related, may have an adverse effect on perinatal outcome. The pregnancy itself can also influence liver diseases by its metabolic alterations and diagnostic and treatment possibilities. Pregnancy in patients with chronic liver diseases is rare because of frequent accompanying phenomena such as anovulation and amenorrhea. Uncomplicated pregnancies with healthy newborns have been reported in all types of chronic liver diseases. Despite improved prognosis, pregnancy in patients with chronic liver diseases should be considered as risky. Currently no chronic liver diseases in any stage is a medical indication to terminate the pregnancy.
