Reasons for Blood Vomiting Explained
Learn the causes of blood vomiting (hematemesis), from ulcers to liver disease. Understand symptoms, when to seek help, diagnosis methods, and treatment options.
Seeing blood in your vomit can be a frightening experience. Known medically as hematemesis, blood vomiting is a serious symptom that should never be ignored. While it may not always indicate a life-threatening condition, it requires immediate medical attention to determine the underlying cause and receive proper treatment.
In this article, we’ll explain the possible reasons for blood vomiting, its symptoms, when to seek help, and how to manage it.
What Does Blood in Vomit Look Like?
Blood in vomit can appear in different ways:
- Bright red blood – Indicates fresh bleeding, usually from the esophagus or stomach.
- Dark brown or coffee-ground-like – Suggests older, partially digested blood, often from stomach ulcers.
The color and texture help doctors identify where the bleeding is coming from.
Common Causes of Blood Vomiting
Several conditions can lead to vomiting blood. Some of the most common include:
1. Gastrointestinal (GI) Bleeding
- Stomach ulcers (Peptic ulcers) – Open sores in the stomach lining caused by infection (H. pylori bacteria) or long-term use of painkillers like aspirin or ibuprofen.
- Gastritis – Inflammation of the stomach lining due to excessive alcohol, spicy foods, or infections.
- Esophageal varices – Swollen veins in the esophagus (common in liver disease patients).
2. Tears in the Esophagus (Mallory-Weiss Tear)
Severe vomiting or coughing can cause small tears in the esophagus, leading to bleeding.
3. Swallowing Blood (From Nosebleeds or Mouth Injuries)
- Sometimes, blood from a nosebleed or dental procedure can be swallowed and later vomited.
4. Severe Acid Reflux or GERD
- Chronic acid reflux can damage the esophagus, causing bleeding.
5. Liver Disease (Cirrhosis)
- Liver damage can increase pressure in blood vessels, leading to bleeding in the stomach or esophagus.
6. Certain Medications
- Blood thinners (like warfarin) or NSAIDs (ibuprofen, aspirin) can increase bleeding risk.
7. Rare but Serious Causes
- Stomach or esophageal cancer
- Blood clotting disorders

Symptoms to Watch For
If you vomit blood, you may also experience:
- Black, tarry stools (indicating digested blood)

Seek emergency medical help if you:

What to Do If You Vomit Blood?
- Stay Calm – Panicking can worsen the situation.
- Do Not Eat or Drink – Avoid food or liquids until a doctor examines you.
- Seek Immediate Medical Help – Call emergency services or go to the nearest hospital.
- Avoid Self-Medication – Do not take painkillers or antacids without consulting a doctor.
Diagnosis and Treatment
Doctors may perform:
- Endoscopy – A thin tube with a camera to check the stomach and esophagus.
- Blood tests – To check for anemia or infections.
- Imaging tests – CT scans or X-rays to locate bleeding.
Treatment depends on the cause:
- Medications – Antibiotics for ulcers, acid reducers for GERD.
- Blood transfusion – If blood loss is severe.
- Surgery – In rare cases (e.g., cancer or severe tears).
Prevention and Lifestyle Tips
To reduce the risk of blood vomiting:
- Avoid excessive alcohol – It irritates the stomach lining.
- Limit NSAIDs – Use painkillers only when necessary.
- Manage acid reflux – Eat smaller meals, avoid spicy foods.
- Treat infections early – H. pylori bacteria can cause ulcers if untreated.
- Stay hydrated – Helps digestion and prevents irritation.
