Abstract
Acute gastrointestinal bleeding (GIB) is potentially a life threatening emergency that remains a common cause of hospitalization with a mortality of about 6% - 13% (holster IL, kuipers EJ 2012). Mortality rates increase in patients with advancing age and increasing number of associated underlying co - morbidities, specifically renal and hepatic dysfunction, heart disease, and malignancies (wilcox CM et al., 1999). Because GIB is a common Hajjees presentation and admission every year to our hospital during Hajj season, and the incidence of adverse outcome of GIB can be reduced by knowing the etiologies, identifying the source of bleeding early and predicting the co-morbid factors associated with its adverse outcome. The study includes a prospective part (1434H) and retrospective part (1432 - 1433H) among pilgrims presented with GIB during Hajj season. This study was conducted at the gastroenterology department of Alnoor specialist Hospital, Holy Makkah, Saudi Arabia. It includes 301 pilgrims with GIB fulfilling the inclusion criteria in Hajj season 1432 - 1434H. 183 patients out of 301 were retrospective (1432H - 1433H) and 118 were prospective 1434H
