A Hepatologist is a medical specialist who diagnoses and treats diseases related to the liver, gallbladder, bile ducts, and pancreas. They manage conditions such as hepatitis, cirrhosis, liver cancer, and fatty liver disease. Hepatologists often work closely with gastroenterologists and may perform procedures like liver biopsies and endoscopic treatments. Their goal is to improve liver health and prevent complications through medical therapy, lifestyle recommendations, and, in some cases, liver transplantation coordination.
