A hepatologist is a medical doctor who specializes in diagnosing and treating diseases of the liver, gallbladder, and bile ducts. They manage conditions such as hepatitis, cirrhosis, and fatty liver disease. Hepatologists often work closely with other healthcare professionals to provide comprehensive care for patients with liver-related issues. These specialists perform various procedures, including liver biopsies and imaging studies, to assess liver health. They also develop treatment plans that may involve medications, lifestyle changes, or referrals for liver transplants. Hepatologists play a crucial role in improving the quality of life for individuals with liver diseases.
