Upper gastrointestinal bleeding originates proximal to the ligament of Treitz. It may present with hematemesis, coffee-ground emesis, melena, or hematochezia when bleeding is rapid and substantial.
The immediate goal is not to identify the precise lesion. It is to recognize instability, begin resuscitation, and determine the urgency of endoscopic treatment.
Recognize The Presentation
Important manifestations include:
- Hematemesis
- Coffee-ground emesis
- Melena
- Dizziness or syncope
- Weakness
- Tachycardia
- Hypotension
- Reduced urine output
- Altered mental status
Melena usually suggests an upper gastrointestinal source, although bleeding from the small bowel or right colon may occasionally produce a similar appearance.
Hematochezia usually suggests lower gastrointestinal bleeding but may occur with a brisk upper gastrointestinal hemorrhage.
Begin With Stabilization
Assess:
- Airway protection
- Breathing and oxygenation
- Circulation
- Mental status
- Hemodynamic stability
- Ongoing bleeding
Obtain adequate intravenous access and send appropriate testing, which may include:
- Complete blood count
- Electrolytes and kidney function
- Liver tests
- Coagulation studies
- Type and screen or crossmatch
- Serial hemoglobin measurements
The initial hemoglobin may not reflect the full magnitude of acute blood loss. Interpret laboratory values together with the clinical presentation.
Consider The Major Causes
Common causes include:
- Peptic ulcer disease
- Esophageal or gastric varices
- Erosive gastritis or duodenitis
- Esophagitis
- Mallory-Weiss tear
- Vascular lesions
- Malignancy
History should include:
- Previous ulcer or bleeding
- Liver disease
- Alcohol use
- Nonsteroidal anti-inflammatory drugs
- Aspirin
- Anticoagulants and antiplatelet therapy
- Glucocorticoids
- Previous endoscopy
- Helicobacter pylori history
Use Risk Stratification
Risk scores complement clinical judgment.
The Glasgow-Blatchford score may help identify very-low-risk patients who could be considered for outpatient management. The American College of Gastroenterology suggests that patients with a score of 0–1 may be eligible for discharge with appropriate follow-up when the remainder of the evaluation is reassuring.
Risk scores should not override instability, ongoing bleeding, significant comorbidities, or clinician concern.
Transfusion And Medications
For most hospitalized patients with upper gastrointestinal bleeding, the ACG guideline suggests a restrictive red blood cell transfusion threshold of approximately 7 g/dL. The decision must still consider active hemorrhage, hemodynamic status, cardiovascular disease, symptoms, and the pace of blood loss.
Proton pump inhibitor therapy is commonly used when peptic ulcer bleeding is suspected.
When variceal bleeding is possible, management may also include:
- Vasoactive therapy
- Antibiotic prophylaxis
- Urgent endoscopic evaluation
- Early coordination with gastroenterology or hepatology
Medication choices and timing depend on the clinical context and local protocols.
Timing Of Endoscopy
The ACG recommends endoscopy within 24 hours after presentation for hospitalized patients, following appropriate initial stabilization.
Endoscopic therapy is recommended for ulcers with:
- Active spurting bleeding
- Active oozing
- A nonbleeding visible vessel
Endoscopy can both identify the lesion and achieve hemostasis.
After Endoscopic Hemostasis
Management may include:
- High-dose proton pump inhibitor therapy
- Monitoring for recurrent bleeding
- Testing and treatment for H. pylori
- Review of NSAID and antithrombotic use
- Secondary prevention
- Repeat endoscopy if rebleeding occurs
If endoscopic therapy fails, transcatheter arterial embolization or surgical management may be required.
Watch For Rebleeding
Possible signs include:
- Recurrent hematemesis
- New melena or hematochezia
- Tachycardia
- Hypotension
- Falling hemoglobin
- Increased transfusion requirement
- New dizziness or syncope
Rebleeding requires prompt reassessment.
High-Yield Framework
When evaluating an upper gastrointestinal bleed, ask:
- Is the airway protected?
- Is the patient hemodynamically stable?
- Is bleeding ongoing?
- Does the patient require transfusion?
- Is a variceal source possible?
- When should endoscopy occur?
- What caused the bleed, and how can recurrence be prevented?
The strongest approach is sequential: stabilize, stratify risk, treat the source, and prevent recurrence.
