Hematemesis was the most frequent presenting symptom (63.5%). Peptic ulcer (duodenal ulcer in most cases) was seen as the main reason for UGIB (42.4%). Rebleeding (present in 16.5% of patients) was found to be more frequent in patients with older age, presenting sign of hematochezia and hypotension, history of taking NSAIDs and smoking, presence of comorbidities, history of bleeding because of UGI tract neoplasm and esophageal varices, history of needing blood products' infusion, and history of therapeutic endoscopy or surgical intervention (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.005). We found that mortality (5.5% in total) was also higher in the same group of patients that were seen to have a higher tendency for rebleeding (<jats:italic>P<\/jats:italic>\u2009&lt;\u20090.005).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Peptic ulcers are the most common cause of UGIB.
