Symptoms and Physical Examination Findings in Upper GI Bleeding
Patients with upper gastrointestinal bleeding most commonly present with hematemesis (vomiting fresh red blood) or melena (black tarry stools), though a minority present with hematochezia (red blood per rectum) in cases of massive bleeding. 1
Primary Clinical Presentations
Overt Bleeding Symptoms
- Hematemesis: Vomiting of fresh red blood, indicating active upper GI bleeding 1
- Coffee ground vomiting: Vomiting of altered black blood, suggesting slower or resolved bleeding 1
- Melena: Passage of black tarry stools, the most common presentation of upper GI bleeding 1
- Hematochezia: Passage of red blood per rectum, occurring in a minority of patients with massive upper GI bleeding 1
Patients presenting with both hematemesis and melena typically have more severe bleeding than those with melena alone. 1
Associated Symptoms
- Abdominal pain may be present, particularly with peptic ulcer disease 2
- Lightheadedness and dizziness from hypovolemia 2
- Syncope in cases of significant blood loss 2
Physical Examination Findings
Hemodynamic Assessment (Critical Priority)
- Tachycardia: Pulse greater than 100 beats/min indicates significant blood loss 1
- Hypotension: Systolic blood pressure less than 100 mm Hg suggests shock 1
- Signs of shock: Cold, pale, and clammy skin 3
- Orthostatic vital sign changes in less severe bleeding 2
Abdominal Examination
- Abdominal tenderness or rebound tenderness should be assessed 2
- Epigastric pain may suggest peptic ulcer disease 2
Rectal Examination
- Fresh red blood on rectal examination indicates active bleeding 1
- Melena on digital rectal exam confirms upper GI source 2
- Stool color assessment is essential for localization 2, 4
Risk Stratification Indicators
High-Risk Clinical Features
- Age greater than 65 years 1
- Shock on presentation (pulse >100, systolic BP <100 mm Hg) 1
- Poor overall health status with significant comorbidities 1
- Evidence of hepatic disease or cardiac failure 1
- Chronic alcoholism or active cancer 1
Laboratory Findings on Presentation
- Low initial hemoglobin levels 1
- Elevated blood urea nitrogen (BUN) - characteristic of upper GI bleeding due to blood protein digestion 1, 5
- Elevated creatinine levels 1
- Elevated serum aminotransferase levels 1
Common Pitfalls to Avoid
Do not assume hematochezia always indicates lower GI bleeding - it can occur with massive upper GI bleeding and requires urgent evaluation. 1
Do not delay hemodynamic assessment - vital signs must be obtained immediately as they determine the urgency of intervention and predict mortality risk. 1, 2
Do not overlook medication history - 80% of patients with bleeding ulcers and erosions use antiplatelet agents, anticoagulants, or NSAIDs, yet only 8.9% receive prophylactic PPIs. 6
Do not miss signs of rebleeding - fresh hematemesis and/or melena with shock, CVP fall >5 mm Hg, or hemoglobin drop >20 g/L over 24 hours indicates rebleeding requiring urgent endoscopy. 1
