Liver disease encompasses a broad range of conditions that impair liver function, a vital organ responsible for detoxification, protein synthesis, and metabolism. These conditions can result from viral infections (e.g., hepatitis), alcohol abuse, autoimmune disorders, genetic factors, or non-alcoholic fatty liver disease. Manifestations vary widely from asymptomatic to severe, including jaundice, fatigue, abdominal pain, and fluid retention. Progressive damage can lead to cirrhosis, liver failure, and hepatocellular carcinoma, necessitating early diagnosis and management.
