Gilbert disease, also known as Gilbert's syndrome, is a genetic disorder that affects the liver's ability to process bilirubin, resulting in mild jaundice. While this condition does not require treatment, it is essential to understand the various names associated with it. Gilbert disease is commonly referred to as constitutional hepatic dysfunction, unconjugated benign bilirubinemia, or familial nonhemolytic jaundice. These synonyms highlight different aspects of this disorder, emphasizing the constitutional and non-threatening nature of the condition, its impact on liver functionality, and its hereditary nature. Recognizing these alternative terms allows individuals to access accurate information and promotes better communication between healthcare professionals and patients.
