In patients with acute<unk>  GI<unk>  who are unstable rapid assessment and resuscitation should be initiated even before diagnostic evaluation. Once hemodynamic stability is achieved, a proper clinical history, physical examination, and initial laboratory findings are crucial not only in determining the likely sources of<unk>  but also in directing the appropriate intervention. In acute GI<unk> , initial hematocrit level measured will not accurately reflect the amount of blood loss. Laboratory findings of chronic<unk>  GI<unk>  include anemia, coagulopathy, and an elevated BUN-to-creatinine ratio.
