Vomiting Blood

Vomiting blood, medically known as hematemesis, is a concerning symptom that requires immediate medical attention. It can be a sign of various underlying medical conditions affecting the gastrointestinal tract, ranging from relatively minor issues to potentially life-threatening emergencies. 

Symptoms of Vomiting Blood

The primary symptom of vomiting blood is the regurgitation of blood from the gastrointestinal tract, often accompanied by other symptoms such as:
  • Blood in Vomit: The presence of blood in vomit, which can range in color from bright red to dark, resembling coffee grounds.
  • Nausea and Vomiting: Feelings of nausea or the urge to vomit, which may precede or accompany the vomiting of blood.
  • Abdominal Pain: Discomfort or pain in the abdominal region, which may vary in intensity depending on the underlying cause.
  • Weakness and Dizziness: Fatigue, weakness, lightheadedness, or dizziness, especially in cases of significant blood loss.

Causes of Vomiting Blood

Vomiting blood can be caused by various factors, including:
  • Peptic Ulcers: Open sores in the lining of the stomach or small intestine, commonly caused by Helicobacter pylori infection, nonsteroidal anti-inflammatory drugs (NSAIDs), or excessive alcohol consumption.
  • Esophageal Varices: Enlarged and swollen veins in the esophagus, typically associated with liver cirrhosis or portal hypertension.
  • Gastritis: Inflammation of the stomach lining, often triggered by infection, NSAID use, alcohol consumption, or autoimmune disorders.
  • Mallory-Weiss Tears: Tears or lacerations in the esophagus due to severe vomiting or retching, leading to bleeding.
  • Gastrointestinal Bleeding: Bleeding from any part of the gastrointestinal tract, including the esophagus, stomach, or intestines, caused by ulcers, tumors, inflammation, or vascular abnormalities.
  • Swallowed Blood: In rare cases, vomiting blood may occur due to swallowing blood from the nose, throat, or mouth, such as in severe nosebleeds or oral injuries.


Diagnosing the underlying cause of vomiting blood involves a thorough evaluation by a healthcare professional, which may include:
  • Physical Examination: The healthcare provider will assess symptoms, perform a physical examination, and inquire about medical history and recent events.
  • Endoscopy: A procedure in which a flexible tube with a camera (endoscope) is inserted into the digestive tract to visualize the esophagus, stomach, and upper part of the small intestine and identify sources of bleeding.
  • Imaging Studies: X-rays, CT scans, or angiography may be performed to locate the source of bleeding and assess the extent of damage.
  • Laboratory Tests: Blood tests may be ordered to check for anemia, clotting disorders, liver function abnormalities, or signs of infection.


Treatment for vomiting blood aims to stabilize the patient, stop the bleeding, and address the underlying cause. Treatment modalities may include:
  • Fluid Replacement: Intravenous fluids may be administered to replace lost fluids and maintain hydration.
  • Blood Transfusion: In cases of severe bleeding and significant blood loss, a blood transfusion may be necessary to restore blood volume and oxygen-carrying capacity.
  • Medications: Proton pump inhibitors (PPIs), antacids, antibiotics (if infection is present), or medications to reduce stomach acid production may be prescribed to treat peptic ulcers or gastritis.
  • Endoscopic Therapy: Techniques such as injection therapy, thermal coagulation, or application of clips or bands may be used to stop bleeding from ulcers, varices, or other sources.
  • Surgery: In some cases, surgery may be required to repair damaged blood vessels, remove tumors, or address underlying conditions causing gastrointestinal bleeding.


Vomiting blood is a serious medical symptom that requires immediate attention and thorough evaluation by a healthcare professional. It can indicate a range of underlying conditions affecting the gastrointestinal tract, from minor issues to potentially life-threatening emergencies. Early diagnosis, prompt intervention, and appropriate treatment are crucial for managing vomiting blood and preventing complications such as shock, anemia, or organ damage. If you experience vomiting blood, seek immediate medical attention to receive proper evaluation and care. Delaying treatment can lead to worsening symptoms and potentially life-threatening consequences.
