• Meckel's

  • Massive haematemesis and melaena from a Meckel's diverticulum. (bmj.com)

  • Causes
  • Causes of "false" melena include iron supplements, Pepto-Bismol, Maalox, and lead, blood swallowed as a result of a nose bleed (epistaxis), and blood ingested as part of the diet, as with consumption of black pudding (blood sausage), or with the traditional African Maasai diet, which includes much blood drained from cattle. (wikipedia.org)
  • symptoms
  • However, aside from the melena itself, many patients may present with few symptoms. (wikipedia.org)
  • Melena strongly suggests, and hematemesis confirms, that bleeding is of upper gastrointestinal origin…Peptic ulcer, the most common cause of gastrointestinal hemorrhage, should be pursued through questions about epigastric distress, the relationship of symptoms to food intake, and a past history of peptic ulcer disease. (wikipedia.org)
  • black
  • Melena or melæna refers to the dark black, tarry feces that are associated with upper gastrointestinal bleeding. (wikipedia.org)
  • Iron supplements may cause a grayish-black stool that should be distinguished from melena, as should black coloration caused by a number of medications, such as bismuth subsalicylate (the active ingredient in Pepto-Bismol), or by foods such as beetroot, black liquorice, or blueberries. (wikipedia.org)
