Upper gastrointestinal bleeding (UGIB) is defined as any blood loss originating from the esophagus, stomach or the proximal duodenum above the ligament of Treitz. Ethnic trends regarding the causes of UGIB have been reported. The aim of this study was to identify the most common causes of UGIB among patients residing in Tabuk city, Saudi Arabia.  Methods  We have conducted a retrospective descriptive cohort study at King Fahad Specialist Hospital (KFSH), Tabuk, Saudi Arabia. All adult patients above the age of 18 years who were suspected of UGIB and referred for esophagogastroduodenoscopy (EGD) were included. The collected data included age, sex, nationality, complaint, EGD, and histopathologic findings.  Results  Between January 1, 2017 and December 31, 2019, 73 patients were included. 83.6% were Saudi, and 64.4% were males. Hematemesis was the main complaint (65.8%). Esophagogastroduodenoscopy was normal in 6.84% of cases; however, it showed UGIB due to esophageal and gastric varices (9.57%) as well as non-variceal causes (83.56%). The most frequent non-variceal findings which represent about two-thirds of the cases were duodenal ulcer (20.53%), antral gastropathy (13.68%), gastric ulcer (12.32%), antral gastritis (10.94%), and duodenal/gastric mass (9.57%), whereas much less frequent findings representing a total of 16.39% of cases included Cameron gastropathy, gastropathy/duodenopathy, esophagitis/gastritis, gastritis/duodenitis, gastroesophageal reflux disease (GERD), and Mallory-Weiss tear.  Conclusion  Non-variceal causes showed higher prevalence as causes of UGIB than variceal causes in the Tabuk area. Furthermore, chronic duodenal and gastric ulcers were the most common culprits of bleeding, whereas duodenitis, gastritis, esophagitis, and Mallory-Weiss syndrome were the least common non-variceal causes.
