The main inciting event in the pathogenesis of upper GI bleeding is damage to mucosal injury. This mucosal injury can occur at various levels of GI tract. If the damage and bleeding is confined up to ligament of Treitz, it is defined as upper GI bleeding. Regardless of etiology, if the balance of gastric acid secretion and mucosal defenses is disrupted, acid interacts with the epithelium to cause damage. | |||

The main inciting event in the pathogenesis of upper GI bleeding is damage to mucosal injury. This mucosal injury can occur at various levels of GI tract. If the damage and bleeding is confined up to ligament of Treitz, it is defined as upper GI bleeding. Regardless of etiology, if the balance of gastric acid secretion and mucosal defenses is disrupted, acid interacts with the epithelium to cause damage.
