Hepatologists are doctors who specialize in the field of hepatic diseases and the organs that these conditions affect. Their goal is to help diagnose and treat hepatic conditions, such as hepatitis, fatty liver disease, pancreatitis, and more.
While hepatology is not a board certified specialty according to the American Board of Medical Specialties (ABMS), it’s generally considered a subspecialty of gastroenterology. It’s only been more recently regarded as separate from gastroenterology in the last few decades.
As such, doctors who are trained in hepatology are also certified in both internal medicine and gastroenterology first.
