Hepatopulmonary (hep-uh-toe-POOL-moe-nar-e) syndrome is an uncommon condition that affects the lungs of people with advanced liver disease. Hepatopulmonary syndrome results in low blood oxygen levels (hypoxemia) caused by blood vessels expanding (dilating) in size and number, which makes it hard for the lungs to deliver adequate amounts of oxygen to the body.

Liver transplant is the only cure for the syndrome.
