Clinical Definition and Presentation

• The medical term for coffee ground vomit is "coffee ground vomiting" or "coffee ground emesis," which is formally defined as the vomiting of altered black blood, according to the British Society of Gastroenterology 1, 2
• Coffee ground vomiting represents a specific presentation of upper gastrointestinal bleeding where blood has been partially digested by gastric acid, giving it a characteristic dark, granular appearance resembling coffee grounds 1, 2

Key Distinguishing Features and Associated Terminology

• The British Society of Gastroenterology recognizes the term "melena" as the passage of black tarry stools, also indicating digested blood, in their clinical guidelines for upper gastrointestinal hemorrhage 1, 2, 3
