Primary biliary cholangitis (PBC) is a chronic autoimmune disease characterized by progressive destruction of the small intrahepatic bile ducts, leading to cholestasis and potential progression to cirrhosis. Prognosis is favorable when diagnosed and treated early, while diagnostic delay is common. Diagnosis is based on elevated ALP and the presence of autoantibodies (AMA/ANA), but the disease is often asymptomatic and detected late.It predominantly affects women aged 40-60 years, and evidence suggests underdiagnosis, highlighting the need for screening strategies in at-risk populations.
