Mucosal lacerations - gastroesophageal junction

A Mallory-Weiss tear occurs in the mucus membrane of the lower part of the esophagus or upper part of the stomach, near where they join. The tear may bleed.

I Would Like to Learn About:

  • Causes

    Mallory-Weiss tears are usually 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

    • Bloody stools
    • Vomiting blood (bright red)
  • Exams and Tests

    • CBC possibly showing low hematocrit
    • Esophagogastroduodenoscopy (EGD), more likely to be done when there is active bleeding
  • Treatment

    The tear usually heals in a few days without treatment. 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 great, 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 usually 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

    Call 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.
