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, fatty liver disease, 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 procedures to manage liver diseases. Hepatologists play a crucial role in improving the quality of life for patients with liver conditions.
