Oral and intravenous formulations may be equivalent; however, the evidence to support this is suboptimal. In those with less severe disease and where endoscopy is rapidly available, they are of less immediate clinical importance. There is tentative evidence of benefit for 935:
by some but by others only in specific situations. Proton pump inhibitors, if they have not been started earlier, are recommended in those in whom high risk signs for bleeding are found. High and low dose PPIs appear equivalent at this point. It is also recommended that people with high risk signs are kept in hospital for at least 72 hours. Those at low risk of re-bleeding may begin eating typically 24 hours following endoscopy. If other measures fail or are not available,

After treatment of a high risk bleeding ulcer endoscopically giving a PPI once or a day rather than as an infusion appears to work just as well and is less expensive (the method may be either by mouth or intravenously). 2204:

Death in those with a GI bleed is more commonly due to other illnesses (some of which may have contributed to the bleed, such as cancer or cirrhosis) than the bleeding itself. Of those admitted to a hospital because of a GI bleed, death occurs in about 7%. Despite treatment, re-bleeding occurs in

Gastrointestinal bleeding from the upper tract occurs in 50 to 150 per 100,000 adults per year. It is more common than lower gastrointestinal bleeding which is estimated to occur at the rate of 20 to 30 per 100,000 per year. Risk of bleeding is more common in males and increases with age.
