Gilbert’s syndrome is a common, benign genetic liver disorder. It causes levels of bilirubin to rise above normal levels. Bilirubin is a yellow chemical by-product of hemoglobin (the red pigment in blood cells) and is usually excreted by the liver as bile.
Gilbert’s syndrome is found in 3%-7% of the US population, affecting up to 10% of some Caucasian populations. This condition usually manifests during the teen years or in adulthood years (ages 20-30).
Gilbert's syndrome is usually caused by an inherited genetic abnormality. Symptoms occur when there is an interference with the liver enzyme that is important in the elimination of bilirubin. This causes the levels of bilirubin to increase in the blood, which may produce symptoms such as jaundice.
