Forrest classification is a classification of upper gastrointestinal hemorrhage used for purposes of comparison and in selecting patients for endoscopic treatment.

[1] Acute hemorrhage Signs of recent hemorrhage Lesions without active bleeding Forrest's classification is instrumental when stratifying patients with upper gastrointestinal hemorrhage into high and low risk categories for mortality.

It is also a significant method of prediction of the risk of rebleeding and very often is used for evaluation of the endoscopic intervention modalities.
