Gastroenterology and Endoscopy

Gastroenterology is the medical specialty dealing with diseases of the digestive system.  

Our specialist Consultants diagnose and treat diseases and disorders of the stomach, duodenum and small and large bowel (colon).  The team also includes two Consultant Hepatologists, who specialise in diseases of the liver.
