A hepatologist is a medical doctor who specializes in diagnosing and treating diseases of the liver, gallbladder, and bile ducts. They focus on conditions such as hepatitis, cirrhosis, and liver cancer. Hepatologists often work closely with other healthcare professionals to provide comprehensive care for patients with liver-related issues. These specialists use various diagnostic tools, including blood tests, imaging studies, and liver biopsies, to assess liver health. Treatment options may include medication, lifestyle changes, or surgical procedures. Hepatologists play a crucial role in managing chronic liver diseases and improving patients' overall health and quality of life.
