Gastroenterology and Endoscopy

Dr. Michael Peters

Gastroenterology focuses on disorders of the digestive system. The digestive system includes the alimentary tract from the mouth to the anus (oesophagus, stomach, small intestine, large intestine, rectum) and organs like the liver, gallbladder and pancreas.

In many countries, including Germany, gastroenterology is a sub-specialisation of internal medicine, which means physicians who are specialised in gastroenterology have to qualify first in internal medicine before they start their gastroenterology training.
