What is Gilbert syndrome? "Bachelor" star Joey Graziadei reveals reason for "yellow eyes"

After receiving comments and questions about his "yellow eyes," "Bachelor" star Joey Graziadei took to social media Thursday to reveal he has Gilbert syndrome, a liver condition that can affect the color of your skin and eyes. 

Gilbert syndrome is an inherited disorder that "affects the liver's ability to process bilirubin, a waste product that forms during the breakdown of old red blood cells," the Cleveland Clinic explains. When too much bilirubin builds up in the blood, jaundice — or yellowish skin and eyes — can occur.

Graziadei says he was diagnosed with Gilbert syndrome when he was in high school, but his health is fine.
