Advances in Understanding Jaundice: Pathophysiology, Diagnostic Approaches, and Therapeutic Interventions

Jaundice is a common clinical condition categorized by yellow staining of the skin, sclera, and mucous membranes caused by elevated levels of bilirubin in the bloodstream. It occurs due to abnormalities in bilirubin metabolism, including increased bilirubin production, impaired hepatic uptake, defective conjugation, or obstruction of bile flow. Jaundice is broadly classified into pre-hepatic, hepatic, and post-hepatic types based on the underlying pathophysiological mechanisms. The condition is associated with a wide spectrum of disorders ranging from hemolytic anemia and viral hepatitis to cholestatic diseases and biliary obstruction. Recent advances in molecular biology, diagnostic imaging, and therapeutics have significantly improved the understanding and management of jaundice. Early detection through biochemical markers and imaging techniques plays a crucial role in determining the etiology and guiding appropriate treatment strategies. Management approaches include pharmacological therapy, phototherapy in neonatal jaundice, endoscopic procedures, surgical interventions, and emerging therapies such as gene therapy and nanotechnology-based drug delivery systems. In addition, herbal medicines with hepatoprotective properties have gained increasing attention as adjunct therapies. This review summarizes recent developments in the pathophysiology, classification, diagnostic approaches, and therapeutic management of jaundice, highlighting current challenges and future research directions. Continued research in hepatology and translational medicine will contribute to improved clinical outcomes and prevention strategies for jaundice worldwide.
