In patients admitted to hospital because of UGI hemorrhage the prognosis depends on age, underlying diseases, hemodynamic status, and the persistence or recurrence of bleeding. The causes of bleeding were not relevant to the prognosis.

Secondary hemorrhage is associated with an increased mortality, which is related to the underlying diseases and not to a difference in the causes of bleeding.

The prognosis of secondary upper gastrointestinal haemorrhage depends on the underlying diseases and on the general condition of the patient, rather than on the actual cause of bleeding.
