Gastroenterology and Hepatology

What is Gastroenterology and Hepatology

Gastroenterology is a category of medicine that concentrates on digestive system functions and its conditions. Disorders that impact the gastrointestinal tract, including all the parts from the mouth to the anus, are the primary focus of this field. Doctors involved with this specialty are known as Gastroenterologists. They carry out several diagnostic and treatment procedures such as Colonoscopy, Fibroscan, Gastroscope, ERCP, Video endoscopy, etc. Hepatology (also known as hepatobiliary medicine) focuses on the function of the liver, biliary tree and pancreas. The physicians with this specialty are called Hepatologists.

In the 1920s and 30s, the nutritionist Victor Lindlah quoted: ‘we are what we eat’. The digestive system is mainly involved in the metabolism of food. The digestive tract begins at the mouth and ends at the bowel. The long journey through the body may sometimes be hindered by dysfunctional organs, disrupting the process of digestion and impacting nutrient absorption. Some of the conditions that can disrupt this seemingly natural process are as follows:

Which Kind of Doctor Specializes in the Treatment of Liver Disorders?

Both gastroenterologists and hepatologists can treat liver diseases, however, their specialty differs. A gastroenterologist focuses on the disorders of GI tract such as colon, pancreas, gallbladder and liver. On the other hand, a hepatologist focuses exclusively on the liver and pancreatic conditions. Both gastroenterologists and hepatologists undergo multiple years of training which includes the diagnosis and treatment of various liver conditions.
