Upper Gastrointestinal Bleeding
Acute upper gastrointestinal bleeding requires immediate hemodynamic assessment, restrictive but context-sensitive transfusion, pre-endoscopic risk stratification, and endoscopy within 24 hours after resuscitation. Management diverges early for suspected variceal hemorrhage and must balance hemostasis against thrombotic risk from interrupted antithrombotic therapy.
First hour
Stabilize and identify patients requiring urgent escalation
Treat hemodynamic instability as a resuscitation problem before a localization problem.
Establish large-bore peripheral IV access, obtain CBC, metabolic panel, coagulation studies, type and screen/crossmatch, and assess for ongoing hematemesis, shock, altered mentation, cardiac ischemia, cirrhosis, and antithrombotic exposure. A structured airway-breathing-circulation approach is appropriate. Routine prophylactic intubation is not supported by observational meta-analyses and has been associated with more aspiration and pneumonia; reserve it for severe hematemesis, agitation, altered consciousness, or inability to protect the airway, with early anesthesia involvement.

Use crystalloid resuscitation with frequent reassessment. A systolic blood pressure target of 90-100 mm Hg has been suggested in guidance, while persistent hypotension after fluids warrants higher-acuity care. BMJBMJUpdate on the management of upper gastrointestinal ... Acute hematemesis with melena is typical, but brisk hematochezia with hemodynamic compromise can represent a massive upper-tract source.

Disposition
Risk stratification and red-cell transfusion
Use pre-endoscopic risk assessment to distinguish low-risk outpatient candidates from patients requiring admission and intervention.
The Glasgow-Blatchford score has the best reported discrimination among commonly used pre-endoscopic scores for need for hospital-based intervention or death. A score of 0 or 1 is the commonly recommended threshold for outpatient management in otherwise appropriate patients. BMJBMJUpdate on the management of upper gastrointestinal ... The ABC score predicts mortality across both upper and lower GI bleeding, but it is a mortality tool rather than a validated discharge rule: in validation cohorts, low (≤3), medium (4-7), and high (≥8) ABC scores corresponded to 30-day mortality of 1.0%, 7.0%, and 25%, respectively, in UGIB. BMJBMJABC score: a new risk score that accurately predicts mortality in acute upper and lower gastrointestinal bleeding: an international multicentre study | Gut
For non-life-threatening bleeding, use a restrictive red-cell transfusion strategy. In a randomized trial of 921 patients, transfusion at hemoglobin below 7 g/dL versus below 9 g/dL was associated with lower 6-week mortality; a meta-analysis of five UGIB trials found lower mortality and rebleeding with restrictive transfusion. BMJBMJUpdate on the management of upper gastrointestinal ... Evidence is insufficient to extrapolate this threshold to exsanguinating hemorrhage or acute coronary syndrome, where clinical context and ongoing loss supersede a single laboratory value. BMJBMJUpdate on the management of upper gastrointestinal ...
Platelet transfusion evidence is limited; a platelet count of 50 × 10^9/L or less is used in some major-hemorrhage protocols, largely on expert consensus. BMJBMJUpdate on the management of upper gastrointestinal ...
The ABC score may help identify high mortality risk but should not replace bedside assessment, hemodynamic trajectory, or UGIB-specific intervention risk assessment.

Definitive treatment
Endoscopy within 24 hours and lesion-directed hemostasis
Endoscopy establishes the source, risk stigmata, and need for definitive endotherapy.
Patients admitted with UGIB should undergo endoscopy within 24 hours of presentation after adequate resuscitation. BMJBMJUpdate on the management of upper gastrointestinal ... In a randomized trial of patients with Glasgow-Blatchford scores of 12 or higher, urgent endoscopy within 6 hours did not reduce 30-day mortality or rebleeding compared with endoscopy at 6-24 hours. BMJBMJUpdate on the management of upper gastrointestinal ... Thus, unresolved shock, airway risk, or inadequate resuscitation should not be bypassed solely to achieve very early endoscopy.
For peptic ulcer bleeding, endoscopic therapy is indicated for active spurting or oozing (Forrest Ia/Ib) and nonbleeding visible vessel (Forrest IIa) lesions. Endotherapy reduces further bleeding and surgery versus no endotherapy in these high-risk groups. BMJBMJUpdate on the management of upper gastrointestinal ... Management of adherent clot (Forrest IIb) remains an area of guideline variation; endoscopic versus medical management alone are both described. Clean-base and flat pigmented lesions (Forrest III/IIc) do not require endoscopic hemostasis. BMJBMJUpdate on the management of upper gastrointestinal ...
Injection, thermal, and mechanical modalities are options for nonvariceal hemostasis, but dilute epinephrine should only be used to improve visualization or provide temporary control before a second modality. Epinephrine monotherapy is inferior to combination treatment for prevention of further bleeding. BMJBMJUpdate on the management of upper gastrointestinal ... If endoscopic hemostasis fails or bleeding recurs after repeat endoscopy, involve interventional radiology for transarterial embolization; surgery is a salvage option. BMJBMJUpdate on the management of upper gastrointestinal ...
Repeat endoscopy is recommended for recurrent bleeding, manifested by recurrent blood loss, a hemoglobin fall exceeding 20 g/L after stabilization, or recurrent tachycardia/hypotension. BMJBMJUpdate on the management of upper gastrointestinal ...
In a randomized trial of rebleeding after initial endoscopic therapy, repeat endoscopy achieved long-term control in 73% and caused fewer complications than surgery. BMJBMJUpdate on the management of upper gastrointestinal ...

Post-endoscopic acid suppression and ulcer-directed follow-up
After endoscopic treatment of high-risk nonvariceal lesions, high-dose proton-pump inhibitor therapy reduces rebleeding, surgery, and mortality. A commonly studied regimen is omeprazole 80 mg IV bolus followed by 8 mg/hour infusion for 72 hours. BMJBMJUpdate on the management of upper gastrointestinal ... High-dose intermittent IV or oral PPI therapy is an evidence-supported alternative to continuous infusion. BMJBMJUpdate on the management of upper gastrointestinal ...
After the initial high-dose course, U.S. and international guidance cited in the review supports twice-daily high-dose oral PPI for 2 weeks in patients with high-risk lesions requiring endotherapy. Test for Helicobacter pylori at index endoscopy, but recognize reduced sensitivity of rapid urease testing and histology during acute bleeding; retest after a negative acute-phase test and eradicate if positive. BMJBMJUpdate on the management of upper gastrointestinal ...
Cirrhosis
Suspected variceal hemorrhage requires early empiric pharmacotherapy
Portal hypertensive bleeding has a distinct early treatment bundle.
In suspected variceal hemorrhage, start a vasoactive agent at presentation and continue for 2-5 days if variceal bleeding is confirmed. Somatostatin, octreotide, and terlipressin reduce portal pressure; randomized evidence summarized in the review supports improved bleeding control, with no clear difference among agents. BMJBMJUpdate on the management of upper gastrointestinal ... The supplied evidence does not provide a U.S. dosing regimen; use current institutional protocols and product-specific labeling.
Give antibiotic prophylaxis promptly in cirrhosis with UGIB. Bacterial infection occurs in 35-66% of patients with cirrhosis and variceal bleeding, and a meta-analysis found lower mortality, rebleeding, and length of stay with empiric antibiotics. Choice should reflect local resistance patterns, with treatment continued for up to 7 days. BMJBMJUpdate on the management of upper gastrointestinal ...
Endoscopic band ligation is the preferred treatment for bleeding esophageal varices. Gastric varices require anatomy-specific treatment; tissue adhesive or thrombin injection is used for most gastric variceal patterns, whereas gastric varices contiguous with esophageal varices along the lesser curvature may be banded. BMJBMJUpdate on the management of upper gastrointestinal ...
If standard endoscopic therapy fails, balloon tamponade or a self-expanding esophageal stent is a bridge to rescue TIPS, not definitive therapy. BMJBMJUpdate on the management of upper gastrointestinal ...
Early preemptive TIPS within 72 hours reduced rebleeding and improved 1-year survival in one trial of selected high-risk patients, although implementation and survival effects have varied across trials. BMJBMJUpdate on the management of upper gastrointestinal ...
| Phase | Action | Purpose |
|---|---|---|
| Before endoscopy | Start vasoactive therapy and antibiotic prophylaxis when variceal bleeding is suspected. BMJBMJUpdate on the management of upper gastrointestinal ... | Reduce portal pressure and infection-associated rebleeding and mortality risk. BMJBMJUpdate on the management of upper gastrointestinal ... |
| Endoscopy | Band bleeding esophageal varices; use anatomy-directed therapy for gastric varices. BMJBMJUpdate on the management of upper gastrointestinal ... | Achieve definitive endoscopic hemostasis. BMJBMJUpdate on the management of upper gastrointestinal ... |

Medication safety
Manage antithrombotics according to bleeding severity and thrombotic indication
Avoid reflex discontinuation of secondary-prevention antiplatelet therapy.
For aspirin used solely for primary prevention, discontinuation after proven UGIB is generally appropriate because absolute vascular benefit is small relative to recurrent bleeding risk. In contrast, continue aspirin used for secondary cardiovascular prevention when feasible. If temporarily withheld for life-threatening bleeding, resume after hemostasis; guideline recommendations cited in the review range from immediate resumption to within 5 days. BMJBMJUpdate on the management of upper gastrointestinal ...
In patients receiving dual antiplatelet therapy with coronary stents, obtain urgent cardiology input. If severe bleeding requires interruption, continue aspirin and withhold the P2Y12 inhibitor temporarily, then restart the P2Y12 inhibitor within 5 days. BMJBMJUpdate on the management of upper gastrointestinal ...
For severe warfarin-associated UGIB, withhold warfarin and use IV vitamin K plus four-factor prothrombin complex concentrate rather than fresh frozen plasma when reversal is necessary. BMJBMJUpdate on the management of upper gastrointestinal ... For direct oral anticoagulants, withholding the agent is generally appropriate except in life-threatening bleeding; idarucizumab and andexanet alfa are reversal options, although the supplied evidence notes cost and potential procoagulant concerns. BMJBMJUpdate on the management of upper gastrointestinal ... Reintroduce anticoagulation after hemostasis with individualized consideration of thrombotic risk; European guidance summarized in the review advises warfarin resumption within 7 days. BMJBMJUpdate on the management of upper gastrointestinal ...
Do not delay endoscopic hemostasis solely for a moderately elevated INR: a case series found similar rebleeding after endotherapy with INR 1.3-2.7 versus INR below 1.3. BMJBMJUpdate on the management of upper gastrointestinal ...
For patients on prasugrel specifically, the FDA label warns that premature discontinuation after ACS/PCI increases stent thrombosis, MI, and death; prasugrel is contraindicated with prior TIA or stroke and should generally be avoided in patients 75 years or older except selected high-risk patients. accessdata fdaaccessdata fdaFDA 1 HIGHLIGHTS OF PRESCRIBING INFORMATION

Avoid error
Avoid common diagnostic and management errors
The most consequential errors are misclassification, premature endoscopy, and incomplete secondary prevention.
Do not assign a lower-tract source solely because of hematochezia. Brisk hematochezia with hemodynamic compromise can arise from UGIB, and 11-15% of patients initially thought to have lower GI bleeding ultimately have an upper source. BMJ+1BMJDiagnosis and management of acute lower gastrointestinal ...BMJUpdate on the management of upper gastrointestinal ...
Pre-endoscopic PPI use may decrease the proportion requiring endoscopic therapy at index endoscopy but has not shown a reduction in mortality, rebleeding, or surgery; guideline positions differ, particularly when endoscopy will be delayed. BMJBMJUpdate on the management of upper gastrointestinal ... This should not substitute for resuscitation, risk assessment, or timely endoscopy.
After ulcer bleeding, ensure H. pylori assessment and follow-up retesting if initial acute-phase testing is negative. In patients exposed to NSAIDs or antithrombotics, reassess the indication, minimize avoidable bleeding-promoting drugs, and document a restart plan before discharge. Evidence supplied supports the antithrombotic principles above but does not provide a specific gastroprotection regimen for every antithrombotic scenario.

Common questions
When should endoscopy be performed for acute upper gastrointestinal bleeding?
Admitted patients should undergo endoscopy within 24 hours after adequate resuscitation. In high-risk patients, endoscopy within 6 hours did not improve 30-day mortality or rebleeding versus endoscopy at 6-24 hours. BMJBMJUpdate on the management of upper gastrointestinal ...
Which patients with upper gastrointestinal bleeding can be managed as outpatients?
A Glasgow-Blatchford score of 0-1 identifies very-low-risk patients who may be suitable for outpatient management, provided they are stable and have no other reason for admission. BMJBMJUpdate on the management of upper gastrointestinal ...
What is the transfusion threshold in upper gastrointestinal bleeding?
For nonexsanguinating UGIB, restrictive transfusion using a hemoglobin threshold near 7 g/dL is supported by randomized and meta-analytic evidence. Do not apply this rigidly to massive ongoing hemorrhage or acute coronary syndrome. BMJBMJUpdate on the management of upper gastrointestinal ...
Should proton-pump inhibitors be started before endoscopy?
Pre-endoscopic PPIs may reduce the need for endoscopic therapy at index endoscopy but have not reduced mortality, rebleeding, or surgery. Guideline recommendations differ, especially if endoscopy is delayed. BMJBMJUpdate on the management of upper gastrointestinal ...
How should recurrent peptic-ulcer bleeding be managed?
Repeat endoscopy is recommended for recurrent bleeding. If repeat endoscopic therapy fails, proceed to transarterial embolization when available; surgery is reserved for refractory cases. BMJBMJUpdate on the management of upper gastrointestinal ...
What should be started before endoscopy when variceal hemorrhage is suspected?
Start vasoactive therapy and antibiotic prophylaxis promptly before endoscopy. Esophageal varices are treated with band ligation, while gastric-varix therapy depends on anatomy. BMJBMJUpdate on the management of upper gastrointestinal ...
