Hepatology is a branch of medicine that focuses on the study, diagnosis, and treatment of diseases related to the liver. The liver is a vital organ that plays a crucial role in digestion, metabolism, and detoxification. Common conditions that hepatologists, or liver specialists, deal with include hepatitis, cirrhosis, and fatty liver disease. Patients with liver issues often experience symptoms like jaundice, fatigue, and abdominal pain. Hepatologists use various tests, such as blood tests and imaging studies, to assess liver function and determine the best treatment options. Their work is essential for maintaining overall health and managing liver-related diseases effectively.
