What

Gilbert syndrome is an inherited disorder in which the liver cannot properly remove bilirubin from the body. Bilirubin is a pigment that is produced when old red blood cells die (a normal process). The liver normally helps clear bilirubin from the body by taking it out of the blood and transporting it into a substance called bile, which is removed through the urine and feces. In Gilbert syndrome, bilirubin is inefficiently removed from the blood and thus accumulates in the body. This excess bilirubin may make the skin appear yellowish in color.

Who

Gilbert syndrome is most common among males and Caucasians (affecting up to 10% of the caucasian population), but it can also be seen in females and people of any racial backgrounds.

Signs and Symptoms

The majority of people with Gilbert syndrome will not experience any symptoms. When symptoms do arise, they are usually mild but can worsen during times of stress, infection, fasting, or physical exertion. A physical sign is mild jaundice (yellow discoloration of the skin and whites of the eyes) and a feeling of fatigue.

Possible Causes

Gilbert syndrome is a genetic disorder involving decreased activity of a certain protein (bilirubin UDP-glucuronosyl-transferase). In a person without Gilbert syndrome, the liver removes bilirubin from the body by taking it out of the blood and attaching it to a substance that makes it easy for the bilirubin to leave the body through the urine and feces in the form of bile. The protein bilirubin UDP-glucuronosyl-transferase helps the processing of bilirubin to bile. In a person with Gilbert syndrome, this protein is deficient, so the bilirubin is not able to leave the body as easily and thus stays in the blood. Its color may give the skin a yellow tint, a condition called jaundice.

Diagnosis

Gilbert syndrome is usually identified through a blood test for bilirubin levels. Your doctor may check other blood tests to make sure there is no other reason for the jaundice. Gilbert syndrome may be confirmed by genetic testing for the protein bilirubin UDP-glucuronosyl-transferase.

Treatment

No treatment is required. Treatment of any underlying infections or halting exertion can help symptoms disappear.

Prognosis

Gilbert syndrome is generally a benign (harmless) condition. People with Gilbert’s live normal lifespans.
