Hematemesis: Signs, Symptoms, Causes, Diagnosis, Treatment & Prevention


Hematemesis, also known as vomiting blood, is a concerning medical condition that can indicate underlying health issues. This article provides a comprehensive overview of hematemesis, including its signs, symptoms, causes, diagnosis, treatment, and prevention strategies.


Hematemesis refers to the act of vomiting blood, a distressing symptom that can stem from various medical conditions. It is crucial to understand the underlying causes of hematemesis to ensure prompt and appropriate medical intervention. This article aims to provide a detailed exploration of hematemesis, shedding light on its different aspects.

Epidemiology of Hematemesis:

Hematemesis is not a standalone disease but a symptom of an underlying condition. Its prevalence varies based on the causes and the population being studied. Gastrointestinal bleeding, the primary cause of hematemesis, is often associated with conditions such as peptic ulcers, esophageal varices, and gastritis. The prevalence of these conditions contributes to the overall occurrence of hematemesis.

Types of Hematemesis:

Types of Hematemesis:

  1. Upper Gastrointestinal Bleeding (UGIB): Upper gastrointestinal bleeding refers to the presence of blood in the vomit originating from the upper part of the digestive tract, which includes the esophagus, stomach, and duodenum. UGIB is a common cause of hematemesis and can result from various conditions, such as:

    • Peptic Ulcers: Open sores in the lining of the stomach or the first part of the small intestine (duodenum) can lead to bleeding and subsequent hematemesis.
    • Gastritis: Inflammation of the stomach lining can cause erosion of blood vessels, resulting in bleeding.
    • Esophageal Varices: Enlarged and swollen veins in the esophagus, often seen in advanced liver disease, can rupture and cause significant bleeding.
    • Mallory-Weiss Tear: Tears in the junction between the esophagus and stomach can occur due to forceful vomiting or retching, leading to bleeding.
  2. Lower Gastrointestinal Bleeding (LGIB): Lower gastrointestinal bleeding involves the presence of blood in vomit that originates from the lower part of the digestive tract, including the small intestine, colon, and rectum. LGIB can result from various conditions, including:

    • Diverticular Disease: Inflammation or bleeding from small pouches (diverticula) in the colon can lead to hematemesis.
    • Colitis: Inflammation of the colon lining, such as in Crohn’s disease or ulcerative colitis, can cause bleeding.
    • Angiodysplasia: Abnormal and fragile blood vessels in the colon can rupture and result in gastrointestinal bleeding.
    • Gastrointestinal Tumors: Cancerous or noncancerous tumors in the digestive tract can cause bleeding and hematemesis.
  3. Mixed Gastrointestinal Bleeding: In some cases, bleeding can occur from both the upper and lower parts of the gastrointestinal tract simultaneously. This mixed bleeding can result from complex conditions that involve multiple areas of the digestive system.

  4. Non-Gastrointestinal Causes: While hematemesis is most commonly associated with gastrointestinal bleeding, there are instances where other factors can lead to blood in vomit. These factors may include:

    • Nosebleeds: Blood from a nosebleed can flow into the throat and be subsequently vomited.
    • Oral Bleeding: Bleeding from the mouth or throat due to dental issues, oral ulcers, or throat infections can cause blood to be present in vomit.
  5. Severity-based Classification: Hematemesis can also be categorized based on the severity of bleeding and the appearance of vomited blood. This classification includes:

    • Frank Hematemesis: Vomiting of fresh, bright red blood, often indicating active bleeding in the upper digestive tract.
    • Coffee-Ground Hematemesis: Vomiting of partially digested blood that appears dark and granular, suggesting slower bleeding and partial digestion of blood in the stomach.
    • Hematochezia: Passage of fresh blood through the rectum, which may be seen in the stool or vomit, indicating lower gastrointestinal bleeding.

Pathophysiology of Hematemesis:

Hematemesis occurs when there is bleeding within the digestive tract, leading to the presence of blood in the vomit. The color and consistency of the vomited blood can provide clues about the location and severity of the bleeding. Bright red blood often suggests active bleeding from a location closer to the mouth, while darker, coffee-ground-like vomit may indicate partially digested blood from a higher location in the gastrointestinal tract.

Risk Factors and Triggers:

Risk Factors and Triggers of Hematemesis:

  1. Chronic Medical Conditions: Individuals with certain chronic conditions are at an increased risk of developing hematemesis due to their potential impact on the gastrointestinal tract. These conditions include:

    • Peptic Ulcers: Chronic ulcers in the stomach or duodenum can lead to bleeding, which may manifest as hematemesis.
    • Liver Cirrhosis: Advanced liver disease can cause portal hypertension, leading to the development of esophageal varices that are prone to bleeding.
    • Inflammatory Bowel Disease (IBD): Conditions like Crohn’s disease and ulcerative colitis can lead to inflammation and ulceration in the digestive tract, increasing the risk of bleeding.
  2. Alcohol Abuse: Excessive alcohol consumption can damage the lining of the stomach and lead to conditions like gastritis and ulcers, which are associated with gastrointestinal bleeding and hematemesis.

  3. Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): Prolonged and high-dose use of NSAIDs, such as aspirin, ibuprofen, and naproxen, can irritate the stomach lining and increase the risk of bleeding ulcers, leading to hematemesis.

  4. Anticoagulant and Blood-Thinning Medications: Drugs that affect blood clotting, such as anticoagulants (e.g., warfarin) and antiplatelet agents (e.g., clopidogrel), can heighten the risk of bleeding and hematemesis.

  5. Helicobacter pylori Infection: This bacterial infection can lead to chronic gastritis and ulcers, increasing the likelihood of gastrointestinal bleeding and hematemesis.

  6. Esophageal Varices: Individuals with advanced liver disease, especially cirrhosis, are at risk of developing esophageal varices. These enlarged veins in the esophagus can rupture, leading to severe bleeding and hematemesis.

  7. Forceful Vomiting or Retching: Repeated episodes of forceful vomiting or retching, as seen in conditions like bulimia or cyclic vomiting syndrome, can cause tears in the esophagus (Mallory-Weiss tears) or increase pressure on the digestive tract, triggering bleeding and hematemesis.

  8. Gastrointestinal Tumors: Cancerous or noncancerous tumors in the gastrointestinal tract can erode blood vessels and lead to bleeding, resulting in hematemesis.

  9. Physical Trauma: Injuries to the abdomen or chest can cause damage to the gastrointestinal tract, leading to bleeding and potential hematemesis.

  10. Stress and Anxiety: Severe stress and anxiety can stimulate excessive stomach acid production and increase the risk of gastrointestinal ulcers and bleeding.

  11. Age: Older adults are more susceptible to gastrointestinal bleeding due to factors like weakened blood vessels, chronic medical conditions, and medication use.

  12. Tobacco Smoking: Smoking can contribute to the development of ulcers and worsen existing gastrointestinal conditions, increasing the risk of bleeding and hematemesis.

  13. Heavy Lifting or Straining: Activities that involve heavy lifting or straining can increase intra-abdominal pressure, potentially triggering bleeding from existing gastrointestinal issues.

Signs & Symptoms of Hematemesis:

Signs & Symptoms of Hematemesis:

  1. Vomiting Blood: The hallmark symptom of hematemesis is the presence of blood in vomit. The blood can vary in color and consistency, providing valuable information about the source and severity of bleeding. Bright red blood indicates active bleeding closer to the mouth, while darker, coffee-ground-like vomit suggests partially digested blood from a higher location in the gastrointestinal tract.

  2. Abdominal Pain: Individuals experiencing hematemesis may also have abdominal pain or discomfort. The nature and location of the pain can vary depending on the underlying cause of the bleeding. Pain may range from mild discomfort to sharp, intense pain.

  3. Dizziness and Weakness: Significant blood loss from gastrointestinal bleeding can lead to a decrease in blood volume and oxygen delivery to tissues. This can result in symptoms of dizziness, lightheadedness, and overall weakness.

  4. Pale Skin and Cold Sweats: Profuse bleeding can lead to decreased oxygen levels in the blood, causing the skin to appear pale or ashen. Cold sweats may also occur due to the body’s attempt to compensate for decreased blood volume.

  5. Nausea and Vomiting: In addition to vomiting blood, individuals may experience persistent nausea and vomiting of non-bloody contents. This can be a result of the underlying condition causing hematemesis.

  6. Hematochezia: While hematemesis refers specifically to vomiting blood, some individuals may experience hematochezia, which involves the passage of fresh blood through the rectum. This can manifest as bloody stools or the presence of blood in the toilet after bowel movements.

  7. Feeling of Fullness or Bloating: Bleeding within the stomach can cause a sensation of fullness or bloating, even after consuming only small amounts of food. This feeling may be uncomfortable and persistent.

  8. Rapid Heart Rate (Tachycardia): In response to decreased blood volume, the heart rate may increase to compensate for reduced oxygen delivery. Tachycardia, or a rapid heart rate, is a common physiological response to significant blood loss.

  9. Hemodynamic Instability: In severe cases of hematemesis, excessive blood loss can lead to hemodynamic instability, characterized by low blood pressure, confusion, and even shock. This is a medical emergency requiring immediate intervention.

  10. Change in Mental Status: Prolonged and severe bleeding can result in reduced oxygen supply to the brain, leading to confusion, disorientation, and changes in mental alertness.

  11. Black, Tarry Stools (Melena): While not directly related to hematemesis, melena refers to black, tarry stools that result from the digestion of blood in the stomach. This occurs when blood interacts with stomach acid and digestive enzymes.

  12. Visible Blood in Saliva: Blood from the upper digestive tract may mix with saliva and result in the appearance of red streaks or spots in saliva.

  13. Gastrointestinal Symptoms: Depending on the underlying cause of hematemesis, individuals may also experience other gastrointestinal symptoms such as indigestion, heartburn, or changes in bowel habits.

  14. Shortness of Breath: Profuse bleeding can lead to decreased oxygen-carrying capacity of the blood, resulting in shortness of breath, especially during physical activity.

Investigation & Diagnosis of Hematemesis:

Investigation & Diagnosis of Hematemesis:

  1. Medical History and Physical Examination: The initial step in diagnosing hematemesis involves a comprehensive medical history and physical examination. The healthcare provider will inquire about the patient’s symptoms, including the nature and frequency of vomiting blood, associated pain, medical history, and any potential risk factors.

  2. Blood Tests: Blood tests can help assess the extent of blood loss and provide information about the patient’s overall health. These tests may include a complete blood count (CBC) to check hemoglobin and hematocrit levels, coagulation studies to evaluate blood clotting, and liver function tests to assess liver health.

  3. Endoscopy: Upper gastrointestinal endoscopy (esophagogastroduodenoscopy or EGD) is a common procedure used to directly visualize the esophagus, stomach, and duodenum. A flexible tube with a camera is inserted through the mouth, allowing the healthcare provider to identify the source of bleeding and assess the severity.

  4. Imaging Studies: Various imaging techniques may be employed to locate the bleeding source and determine the extent of the condition. These include:

    • Angiography: A dye is injected into blood vessels to identify areas of active bleeding or blood vessel abnormalities.
    • Computed Tomography (CT) Scan: CT scans can provide detailed images of the abdomen, helping identify potential bleeding sources.
    • Capsule Endoscopy: A small, swallowable camera capsule can capture images of the entire gastrointestinal tract as it passes through, aiding in the diagnosis of bleeding sources in the small intestine.
  5. Stool and Urine Tests: Stool tests may be conducted to check for the presence of blood (occult blood) that may not be visible to the naked eye. Urine tests can help assess kidney function and screen for blood-related abnormalities.

  6. Upper Gastrointestinal Series (Barium Swallow): This imaging study involves drinking a contrast solution containing barium, which outlines the upper gastrointestinal tract on X-rays. It can help identify structural abnormalities or bleeding sources.

  7. Biopsy: During endoscopy, a biopsy (tissue sample) may be taken from suspicious areas for further examination under a microscope. This can help determine the underlying cause of the bleeding.

  8. Catheter-based Techniques: In some cases, catheters may be used to deliver treatments directly to bleeding sites. Techniques such as cauterization, injection of medications, or the placement of clips or bands can be performed to stop bleeding during endoscopy.

  9. Esophageal pH Monitoring: This test measures the acidity levels in the esophagus and can help diagnose conditions such as gastroesophageal reflux disease (GERD), which might contribute to hematemesis.

  10. Esophageal Manometry: Esophageal manometry assesses the function and motility of the esophagus, which can provide insights into conditions affecting its structure and movement.

  11. Helicobacter pylori Testing: Testing for H. pylori infection, a common cause of stomach ulcers, can be performed through blood, breath, or stool tests.

  12. Liver Function Tests: Given the association between liver disease and esophageal varices, liver function tests may be conducted to evaluate liver health and identify potential contributing factors.

  13. Cardiac Evaluation: In cases where heart-related issues are suspected, an electrocardiogram (ECG) or other cardiac tests may be performed to rule out heart-related causes of symptoms.

  14. Medical Imaging of Lower Gastrointestinal Tract: If lower gastrointestinal bleeding is suspected, diagnostic techniques such as colonoscopy or flexible sigmoidoscopy may be employed to visualize the colon and rectum and identify potential sources of bleeding.

Treatment of Hematemesis in Modern Medical Science:

Treatment of Hematemesis in Modern Medical Science:

  1. Stabilization and Supportive Care: In cases of severe bleeding and hemodynamic instability, the immediate priority is to stabilize the patient’s condition. This may involve intravenous fluids, blood transfusions, and oxygen therapy to restore blood volume, maintain blood pressure, and ensure adequate oxygen delivery to tissues.

  2. Correction of Coagulation Disorders: If bleeding is due to coagulation disorders or medication-related effects, appropriate interventions may be undertaken to normalize blood clotting function. This could include adjusting dosages of anticoagulant medications or providing clotting factor replacements.

  3. Proton Pump Inhibitors (PPIs): Proton pump inhibitors are medications that reduce stomach acid production. They are commonly prescribed to manage conditions like peptic ulcers, gastritis, and gastroesophageal reflux disease (GERD), which can contribute to gastrointestinal bleeding.

  4. Endoscopic Interventions: Endoscopy can be used not only for diagnosis but also for therapeutic interventions. Techniques such as injection therapy, thermal coagulation, and placement of clips or bands can be employed to stop active bleeding from ulcers or varices.

  5. Sclerotherapy and Band Ligation: For individuals with esophageal varices, sclerotherapy or band ligation can be performed during endoscopy to close off and treat the swollen veins, reducing the risk of future bleeding.

  6. Transjugular Intrahepatic Portosystemic Shunt (TIPS): In cases of severe liver disease with recurrent variceal bleeding, a TIPS procedure may be considered. This involves creating a shunt within the liver to redirect blood flow and reduce portal hypertension.

  7. Surgical Interventions: Surgical procedures may be necessary for cases where endoscopic therapies are not effective or for managing more extensive bleeding. Surgical options include ligation, resection, or vessel repair.

  8. Medical Management of Underlying Conditions: Treating the underlying cause of hematemesis is crucial for long-term management. This may involve addressing conditions like peptic ulcers, liver disease, or inflammatory bowel disease through targeted medical therapies.

  9. Medications to Control Bleeding: In cases of active bleeding, medications like vasopressin or octreotide may be used to constrict blood vessels and reduce blood flow to the bleeding site.

  10. Antibiotics: Antibiotics may be prescribed to prevent infections related to bleeding from ulcers or varices, particularly if the liver is compromised.

  11. Lifestyle Modifications: Patients may be advised to make certain lifestyle changes, such as avoiding alcohol, tobacco, and NSAIDs, to reduce the risk of further bleeding.

  12. Nutritional Support: Adequate nutrition is essential for healing and recovery. In some cases, nutritional supplementation may be recommended to support the healing of ulcers or improve overall nutritional status.

  13. Long-Term Management: For chronic conditions such as liver disease, ongoing monitoring and management are essential to prevent recurrent bleeding episodes. This may involve regular medical check-ups, medication adjustments, and lifestyle modifications.
