Depending on the amount of the blood loss, symptoms may include shock. Upper gastrointestinal bleeding can be caused by peptic ulcers, gastric erosions, esophageal varices, and rarer causes such as gastric cancer. The initial assessment includes measurement of the blood pressure and heart rate, as well as blood tests to determine the hemoglobin.
