A British man says he watched his skin turn a striking shade of yellow as a rare, life-threatening liver condition he was born with flared up earlier this year, ultimately requiring a second liver transplant to save his life. Left untreated, the condition can cause severe jaundice and progressive liver damage. He underwent his first liver transplant at 11 months old and went on to live a healthy life for more than a decade afterward. His skin and eyes turned a vivid yellow, a hallmark sign of severe jaundice caused by the buildup of bilirubin when the liver and bile ducts stop functioning properly. He spent five weeks receiving treatment in the hospital before undergoing his second liver transplant in late February.
