Starship Paediatric Gastroenterology and Hepatology
The presence of blood in vomit or in the stool is a common reason for children to be referred for endoscopy. The blood may be red or sometimes will become tarry black. The cause will depend on the age of the child and may include oesophageal varices, peptic ulcer, gastro-oesophageal reflux, Helicobacter pylori infection, allergic colitis, colonic polyps or inflammatory bowel disease. The best method of finding the cause is a gastroscopy or colonoscopy.
