Disease: Hepatopulmonary Syndrome
Symptoms: Most people with hepatopulmonary syndrome have no symptoms. If symptoms occur, they may include:  Shortness of breath, especially when sitting or standing Clubbing of the fingers, in which the fingertips spread out and become rounder than normal Broken blood vessels under the skin (spider angioma) Bluish tinge of the lips and skin (cyanosis)  Causes Hepatopulmonary syndrome is caused when blood vessels in and around the lungs widen (dilate), which affects the amount of oxygen that moves from the lungs into the bloodstream. What causes this abnormality remains unclear, and it's unknown why some people with liver disease develop hepatopulmonary syndrome while others do not.
