What is Gastroenterology?

Gastroenterology is the medical specialty that deals with the diagnosis and treatment of disorders and diseases of the gastrointestinal (GI) tract, also called the digestive tract. Gastroenterologists evaluate a patient's condition by performing various outpatient tests, such as upper and lower GI series (x-rays of the digestive tract), as well as surgery.
