Gilbert’s Syndrome Treatment

Gilbert’s syndrome is caused by lack or deficiency of an enzyme uridine-diphosphate glucuronosyltransferase or UGT. This enzyme is responsible for converting fat soluble free or unconjugated bilirubin into water soluble conjugated bilirubin which is then excreted from the body. Bilirubin thus helps in excretion of the heme derived from the dead red blood cells. Diagnosis of Gilbert’s syndrome Gilbert’s syndrome […]
