Causes

Mallory-Weiss tears are most often caused by forceful or long-term vomiting or coughing. They may also be caused by epileptic convulsions.

Any condition that leads to violent and lengthy bouts of coughing or vomiting can cause these tears.

Symptoms

Symptoms may include:

Exams and Tests

Tests may include:

Treatment

The tear usually heals in a few days without treatment. The tear may also be fixed by clips that are put in during an EGD. Surgery is rarely needed. Drugs that suppress stomach acid (proton pump inhibitors or H2 blockers) may be given, but it is not clear if they are helpful.

If blood loss has been large, blood transfusions may be needed. In most cases, bleeding stops without treatment within a few hours.

Outlook (Prognosis)

Repeated bleeding is uncommon and the outcome is most often good. Cirrhosis of the liver and problems with blood clotting make future bleeding episodes more likely to occur.

Possible Complications

Hemorrhage (loss of blood)

When to Contact a Medical Professional

Contact your health care provider if you begin vomiting blood or if you pass bloody stools.

Prevention

Treatments to relieve vomiting and coughing may reduce risk. Avoid excessive alcohol use.
