A 74-year-old retired builder presents to the medical assessment unit with a 2-day history of tiredness, weakness and dark stool. There is no history of weight loss, anorexia, dysphagia or change in bowel habit. Signifiant past medical history includes atrial fibrillation, for which he is receiving warfarin, and gastro-oesophageal reflex disease (GORD) but no previous history of peptic ulceration. Over the last 5 days he had also been receiving ciproflxacin for a presumed urinary tract infection (UTI). Examination demonstrates conjunctival pallor and melaena. Initial investigations reveal an Hb of 8.5 and an INR of 6.9. LFTs are normal.
