Gastrointestinal Hemorrhage

A serious medical emergency involving bleeding within the digestive tract that requires immediate medical attention and treatment

Emergency Symptoms

Overview

Gastrointestinal hemorrhage (GI bleeding) is a serious medical condition characterized by bleeding from any location within the gastrointestinal tract, from the esophagus to the rectum. This condition represents a medical emergency that can be life-threatening, requiring immediate evaluation and treatment by healthcare professionals.

GI bleeding is broadly classified into two categories: upper gastrointestinal bleeding (UGIB), which occurs above the ligament of Treitz (duodenojejunal junction), and lower gastrointestinal bleeding (LGIB), which occurs below this anatomical landmark. The distinction is important for diagnostic and therapeutic approaches, as the causes, presentation, and management strategies differ significantly between the two types.

The severity of gastrointestinal hemorrhage can range from minor bleeding that may go unnoticed to massive hemorrhage causing hemodynamic instability and shock. The annual incidence of GI bleeding is approximately 100-200 per 100,000 adults, with upper GI bleeding being more common than lower GI bleeding. The condition affects all age groups but is more prevalent in older adults, particularly those with multiple comorbidities.

Early recognition and prompt treatment are crucial for optimal outcomes. The mortality rate varies depending on the underlying cause, patient age, comorbidities, and the speed of medical intervention. With appropriate treatment, many cases of GI bleeding can be successfully managed, but delays in treatment can lead to severe complications including hemorrhagic shock, organ failure, and death.

Symptoms

The symptoms of gastrointestinal hemorrhage vary depending on the location, severity, and acuity of bleeding. Recognition of these symptoms is critical for prompt medical intervention and optimal patient outcomes.

Overt Bleeding Symptoms

  • Hematemesis (vomiting blood): Vomiting bright red blood or coffee-ground appearing material, indicating upper GI bleeding
  • Hematochezia (blood in stool): Passage of bright red blood or maroon-colored stools, typically from lower GI bleeding
  • Melena: Black, tarry, foul-smelling stools resulting from digested blood, usually from upper GI bleeding
  • Rectal bleeding: Visible blood on toilet paper or in toilet bowl, often from lower GI sources

Hemodynamic Symptoms

  • Dizziness and lightheadedness: Due to decreased blood volume and reduced cerebral perfusion
  • Syncope (fainting): Loss of consciousness from severe blood loss and hypotension
  • Weakness and fatigue: Generalized weakness due to anemia and reduced oxygen-carrying capacity
  • Orthostatic symptoms: Dizziness or fainting when standing due to volume depletion

Gastrointestinal Symptoms

  • Nausea: Often accompanies vomiting and may precede hematemesis
  • Vomiting: May contain blood or occur without blood in cases of severe bleeding
  • Abdominal pain: Can range from mild discomfort to severe pain, depending on the underlying cause
  • Diarrhea: May occur with lower GI bleeding or as a result of blood acting as a cathartic

Systemic Symptoms

  • Tachycardia: Rapid heart rate as the body attempts to maintain cardiac output
  • Hypotension: Low blood pressure from significant blood loss
  • Pallor: Pale skin and mucous membranes due to anemia
  • Cold, clammy skin: Signs of shock and peripheral vasoconstriction
  • Shortness of breath: Compensatory mechanism for decreased oxygen-carrying capacity

Changes in Stool Appearance

  • Color changes: From bright red to dark maroon to black, depending on bleeding location
  • Consistency changes: Loose or liquid stools mixed with blood
  • Frequency changes: Increased bowel movements with blood-tinged stools
  • Odor changes: Foul, metallic odor particularly with melena

Severity Classification

  • Mild bleeding: Minimal symptoms, stable vital signs, minimal blood loss
  • Moderate bleeding: Orthostatic changes, mild tachycardia, noticeable blood loss
  • Severe bleeding: Hemodynamic instability, shock, massive blood loss requiring immediate intervention
  • Massive bleeding: Life-threatening hemorrhage with cardiovascular collapse

Chronic vs. Acute Presentation

  • Acute bleeding: Sudden onset of symptoms with hemodynamic changes
  • Chronic bleeding: Gradual onset with symptoms of anemia such as fatigue and weakness
  • Intermittent bleeding: Episodes of bleeding separated by symptom-free periods

Associated Symptoms

  • Chest pain: May occur due to decreased cardiac perfusion
  • Confusion: Altered mental status from decreased cerebral perfusion
  • Anxiety: Natural response to the frightening nature of bleeding
  • Thirst: Body's response to volume depletion

Causes

Gastrointestinal hemorrhage can result from numerous underlying conditions affecting different parts of the digestive tract. Understanding the causes is essential for appropriate diagnosis and treatment.

Upper Gastrointestinal Bleeding Causes

  • Peptic ulcer disease: Most common cause of UGIB, including gastric and duodenal ulcers often associated with H. pylori infection or NSAID use
  • Esophageal varices: Dilated veins in the esophagus due to portal hypertension, commonly seen in cirrhosis
  • Mallory-Weiss tear: Longitudinal tear in the esophageal mucosa due to sudden increase in intra-abdominal pressure
  • Boerhaave syndrome: Full-thickness rupture of the esophagus, a surgical emergency
  • Erosive esophagitis: Inflammation of the esophageal lining due to acid reflux
  • Gastric cancer: Malignant tumors in the stomach can cause bleeding

Lower Gastrointestinal Bleeding Causes

  • Diverticular disease: Bleeding from diverticular pouches, particularly common in elderly patients
  • Colorectal cancer: Malignant tumors anywhere in the colon or rectum
  • Inflammatory bowel disease: Crohn's disease and ulcerative colitis causing chronic inflammation
  • Hemorrhoids: Swollen anal veins, often causing minor bleeding
  • Anal fissures: Small tears in the anal lining causing bleeding during bowel movements
  • Angiodysplasia: Abnormal blood vessels in the colon wall, common in elderly patients

Medication-Related Causes

  • NSAIDs (Non-steroidal anti-inflammatory drugs): Increase risk of peptic ulcers and GI bleeding
  • Anticoagulants: Warfarin, heparin, and newer oral anticoagulants increase bleeding risk
  • Antiplatelet agents: Aspirin, clopidogrel, and other antiplatelet medications
