Gastroenterology looks at the diseases and disorders of the digestive system. Gastroenterologists are studying the physiology of the gastrointestinal organs including how food is moving through the stomach and intestine, how nutrients are being digested and absorbed, how the waste is removed and the normal function of the liver.

This field has recently been revolutionised with the introduction of the fibre-optic endoscope, a miniature video camera that enables the consultant to examine the digestive tract. Other new imaging techniques such as CT scans and ultrasound mean a more accurate diagnosis and earlier treatment is possible.
