Blood in Vomit: Causes and When to Seek Help - Gastroenterology and Hepatology

Vomiting with blood?

Feeling bloated after eating too much at night and then inducing vomiting can be concerning, especially if you noticed blood in the vomit.
The presence of blood, even if it was only in one instance, could indicate a potential issue such as irritation or damage to the lining of the stomach or esophagus, which may lead to bleeding.
This could be due to various reasons, including excessive vomiting, gastritis, or other gastrointestinal conditions.
It is important to seek medical attention promptly to evaluate the situation and determine the underlying cause of the bleeding.
Please consult a healthcare professional for a thorough assessment and appropriate management.

Dr. Lin Minghui reply Gastroenterology and Hepatology

Hello, vomiting or severe vomiting, such as after excessive alcohol consumption, can cause injury to the gastric and esophageal mucosa, leading to bleeding.
The most common injury is a tear at the esophagogastric junction, which is usually minor and can heal on its own.
However, if there are underlying conditions, liver disease, or coagulopathy, and if there is significant bleeding, medical attention is necessary.
Best wishes, Dr.

More Info

Vomiting blood, known medically as hematemesis, can be alarming and may indicate a serious underlying condition. In your case, the presence of blood in the vomit after inducing vomiting could be due to several reasons, and it’s essential to understand these causes and when to seek medical help.

Possible Causes of Blood in Vomit
1. Gastric Irritation or Injury: Inducing vomiting can irritate the lining of the stomach and esophagus. This irritation can lead to small tears or abrasions, which may cause bleeding. This is often referred to as Mallory-Weiss syndrome, where tears occur at the junction of the stomach and esophagus due to forceful vomiting.

2. Peptic Ulcers: These are sores that develop on the lining of the stomach or the upper part of the small intestine. If an ulcer bleeds, it can result in blood being present in vomit. Symptoms may include a burning stomach pain, bloating, and indigestion.

3. Gastroesophageal Reflux Disease (GERD): Chronic acid reflux can lead to inflammation of the esophagus (esophagitis), which may cause bleeding and result in blood in vomit.

4. Esophageal Varices: In individuals with liver disease, swollen veins in the esophagus can rupture and bleed, leading to hematemesis. This is a more severe condition and requires immediate medical attention.

5. Other Conditions: Other potential causes include gastritis (inflammation of the stomach lining), tumors in the stomach or esophagus, and systemic conditions that affect blood clotting.

When to Seek Medical Help
Given the potential seriousness of vomiting blood, it is crucial to seek medical attention if you experience any of the following:
- Persistent Vomiting: If vomiting continues, especially if it is accompanied by blood.

- Large Amounts of Blood: If the amount of blood is significant or if it appears to be bright red or resembles coffee grounds.

- Accompanying Symptoms: If you experience symptoms such as severe abdominal pain, dizziness, fainting, or signs of shock (like rapid heartbeat, pale skin, or confusion).

- Underlying Health Conditions: If you have a history of liver disease, ulcers, or any other gastrointestinal issues.

Conclusion
In your specific situation, since you mentioned that the blood was present only in the last few bites of vomit and that you typically do not experience stomach discomfort, it may be a result of irritation from the vomiting itself. However, it is essential to take this symptom seriously. If the bleeding persists or if you develop any concerning symptoms, it is advisable to consult a healthcare professional promptly for a thorough evaluation. They may perform diagnostic tests such as an endoscopy or imaging studies to determine the cause of the bleeding and recommend appropriate treatment.
Remember, while some causes of blood in vomit can be benign, others can be life-threatening, so erring on the side of caution is always the best approach.
