What is Gastroenterology? Gastroenterology is the study of the functions of the digestive tract including esophagus, stomach, small intestine, colon and rectum, pancreas, gallbladder, bile ducts and liver. This includes such conditions as acid reflux disease, colitis, colon polyps and ulcers.
The gastroenterology medical specialty focuses on diagnosis and treatment of the digestive system and medical conditions affecting it. The length of the gastrointestinal tract spans from mouth to anus. Testing and gastroenterology procedures are performed all along the gastrointestinal tract, and may be localized in different areas depending on your condition or symptoms.
