Upper gastrointestinal (GI) bleeding is bleeding from the oesophagus, stomach or duodenum, above the ligament of Treitz. It is a common medical emergency, and a major bleed can quickly lead to shock. Rapid resuscitation, risk assessment and early endoscopy save lives.
Causes
- Peptic ulcer disease — the most common cause, linked to H. pylori and NSAIDs.
- Oesophageal and gastric varices — in liver cirrhosis and portal hypertension.
- Oesophagitis and gastritis.
- Mallory–Weiss tear — after forceful vomiting.
- Upper GI cancers.
- Vascular lesions, such as angiodysplasia and Dieulafoy lesion.
Clinical features
- Haematemesis: vomiting fresh red blood or "coffee-ground" material.
- Melaena: black, tarry, offensive stools.
- A brisk upper GI bleed can also cause fresh red blood per rectum, together with shock.
- Signs of blood loss:
- tachycardia
- hypotension, including a postural drop
- pallor
- dizziness or fainting
- reduced urine output
- Look for clues to the cause:
- signs of chronic liver disease (suggesting varices)
- NSAID, anticoagulant or antiplatelet use
- alcohol use
- weight loss
Immediate management
- Assess and resuscitate (ABCDE).
- Two large-bore IV cannulas.
- Send bloods:
- full blood count
- urea and electrolytes (urea rises in upper GI bleeding)
- liver function
- clotting
- group and cross-match
- Give fluids and blood as needed.
- Transfusion: a restrictive strategy is generally used. Transfuse at a haemoglobin of about 70 g/L, or higher (about 80 g/L) in patients with cardiovascular disease. Massive bleeding needs the major haemorrhage protocol.
- Correct clotting problems and review anticoagulants and antiplatelets with seniors.
- Risk assessment: the Glasgow-Blatchford score before endoscopy identifies very low-risk patients who may be managed as outpatients. The Rockall score after endoscopy predicts the risk of rebleeding and death.
- Endoscopy within 24 hours of presentation for most patients, and immediately after resuscitation in unstable patients.
Specific treatment
- Non-variceal (ulcer) bleeding:
- endoscopic therapy, using a combination of methods such as adrenaline injection with clips or thermal coagulation
- followed by high-dose PPI
- test for and treat H. pylori
- Variceal bleeding:
- terlipressin and prophylactic antibiotics before endoscopy
- then endoscopic band ligation for oesophageal varices
- for gastric varices, glue injection (cyanoacrylate)
- a balloon tamponade tube as a temporary bridge
- then a TIPS procedure (transjugular intrahepatic portosystemic shunt)
Exam pearls
- Raised urea with normal creatinine suggests an upper GI bleed: digested blood protein is absorbed.
- In suspected variceal bleeding, always give terlipressin and antibiotics.
- Haemoglobin may be normal early in an acute bleed, because it has not yet been diluted.

Most common cause of upper GI bleeding:
- Varices
- Angiodysplasia
- Cancer
- Peptic ulcer disease
- Mallory–Weiss tear
Show answer
Answer: D. Peptic ulcer disease
Peptic ulcers, linked to H. pylori and NSAIDs, are the commonest cause.Which score identifies very low-risk patients before endoscopy?
- Wells
- CURB-65
- Glasgow-Blatchford
- Child–Pugh
- Rockall
Show answer
Answer: C. Glasgow-Blatchford
Glasgow-Blatchford is used pre-endoscopy; Rockall is used after endoscopy.Why is urea raised with normal creatinine in upper GI bleeding?
- Kidney failure
- Dehydration only
- Lab error
- Absorption of digested blood protein
- Liver failure
Show answer
Answer: D. Absorption of digested blood protein
Blood in the gut is digested and absorbed as protein, raising urea.Usual transfusion threshold in most patients with acute upper GI bleeding:
- Hb 70 g/L (higher, about 80, with cardiovascular disease)
- Never transfuse
- Hb 50 g/L
- Hb 120 g/L
- Always transfuse
Show answer
Answer: A. Hb 70 g/L (higher, about 80, with cardiovascular disease)
A restrictive transfusion strategy improves outcomes in most patients.Endoscopic treatment of choice for bleeding oesophageal varices:
- Adrenaline injection alone
- Surgery first
- Band ligation
- Argon plasma only
- Clips
Show answer
Answer: C. Band ligation
Endoscopic band ligation is first-line for oesophageal variceal bleeding.
