Gastroenterologist

A gastroenterologist is a medical specialist trained to diagnose and treat diseases of the digestive system, including the oesophagus, stomach, small intestine, colon, rectum, liver, pancreas, and bile ducts. They use endoscopy and imaging techniques to examine and treat gastrointestinal disorders. They also play a key role in colorectal cancer prevention and management of chronic conditions such as Crohn's disease and ulcerative colitis.
