For Patients & General Readers

An upper GI bleed is bleeding that occurs in the digestive tract from the esophagus down to the first part of the small intestine. It can happen to anyone but is more common in older adults or those with certain medical conditions. Recognizing the signs is crucial for prompt medical attention to prevent serious complications.

Clinical Overview

Upper gastrointestinal (GI) bleeding is defined as hemorrhage originating proximal to the ligament of Treitz, manifesting as hematemesis or melena. It represents a spectrum of severity, from occult blood loss to life-threatening exsanguination, necessitating rapid assessment and resuscitation.

Clinical Presentation

Hematemesis (vomiting blood), which can be bright red or look like coffee grounds.
Melena (black, tarry stools) indicating digested blood.
Hematochezia (bright red blood per rectum) can occur with massive upper GI bleeds.
Abdominal pain, which may be related to the underlying cause (e.g., ulcer).
Signs of hypovolemia such as tachycardia, hypotension, and dizziness.
Syncope or near-syncope.
Anemia symptoms like fatigue and pallor.

Signs & Symptoms

Symptoms (Patient-Reported)

Vomiting blood (bright red or coffee-ground appearance)
Black, tarry stools
Dizziness or lightheadedness
Weakness or fatigue
Shortness of breath
Abdominal pain or cramping
Feeling faint

Signs (Clinician-Observed)

Tachycardia
Hypotension (especially postural)
Pallor
Cool, clammy skin
Abdominal tenderness
Nasogastric tube aspirate showing blood

Differential Diagnoses

Condition	Distinguishing Feature
Lower Gastrointestinal Bleed	Typically presents with hematochezia, though massive upper GI bleeds can also cause this. Location of bleeding is distal to the ligament of Treitz.
Epistaxis	Bleeding from the nose, can be swallowed and mistaken for hematemesis.
Hemorrhoid/Anal Fissure Bleeding	Bright red blood on toilet paper or in the toilet bowl, usually with defecation. Melena is absent.
Esophageal Candidiasis/Infection	May cause dysphagia and odynophagia, but significant bleeding is uncommon unless associated with erosions or ulcers.
Medication Side Effects (e.g., NSAIDs, Anticoagulants)	These are risk factors and causes, not differential diagnoses for the bleeding itself, but important to consider in the etiology.
Gastric/Duodenal Ulcer Disease	A common cause of upper GI bleed, presenting with epigastric pain and potential bleeding.
Esophageal Varices	Dilated veins in the esophagus, often associated with portal hypertension (e.g., cirrhosis), a common cause of severe upper GI bleeding.

Red Flags — Seek Immediate Care

Hemodynamic instability (hypotension, tachycardia, shock)
Massive hematemesis or melena
Altered mental status
Significant comorbidities (e.g., advanced liver disease, cardiovascular disease)

Key Investigations

Complete blood count (CBC) to assess for anemia and platelet count.
Coagulation studies (PT/INR, aPTT) to assess for coagulopathy.
Liver function tests (LFTs) to assess for liver disease, a risk factor for variceal bleeding.
Endoscopy (esophagogastroduodenoscopy - EGD) is the gold standard for diagnosis and often therapeutic intervention.
Nasogastric (NG) tube lavage to assess for the presence and nature of blood.
Imaging studies (e.g., CT angiography) may be considered in specific situations for active bleeding not amenable to endoscopy.

Management Overview

Initial management focuses on hemodynamic resuscitation with intravenous fluids and blood products as needed, alongside correction of coagulopathy. Definitive diagnosis and treatment are typically achieved with urgent upper endoscopy, which allows for visualization, biopsy, and therapeutic interventions such as cautery, clipping, or injection therapy.
