GI Bleed — Clues Before the Obvious Bleed
GI bleeding can declare itself before frank hematemesis or hematochezia.
Trend hemoglobin, but know its limits
Early acute blood loss may not immediately lower hemoglobin. Serial values, hemodynamics, symptoms, and volume resuscitation affect interpretation.
Look for indirect clues
Melena, orthostasis, tachycardia, rising BUN relative to creatinine, iron deficiency, fatigue, syncope, or unexplained anemia can point toward GI blood loss.
Medication history matters
Anticoagulants, antiplatelets, NSAIDs, steroids, and alcohol can change bleeding risk or the likely lesion.
Stability drives disposition
Active bleeding, syncope, hypotension, ischemic symptoms, rapid hemoglobin decline, or ongoing significant blood loss requires urgent evaluation.
