What is Mallory Weiss syndrome

Mallory Weiss syndrome is more commonly known as Mallory-Weiss tear, which is a tear the tissue of your lower esophagus caused by forceful vomiting and are typically located at the gastroesophageal junction 1. Your esophagus is the tube that carries food from your throat to your stomach. It plays a vital role in digestion. Sometimes, a tear the tissue of your lower esophagus and it can start to bleed. The condition is called a Mallory-Weiss tear.

Mallory Weiss syndrome (Mallory-Weiss tear) is most often caused from forceful or long-term vomiting or coughing. Mallory Weiss syndrome (Mallory-Weiss tear) may also be caused by epileptic convulsions. Less common causes are a hiatal hernia, or childbirth, which can increase pressure in your abdomen.

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

Mallory Weiss syndrome (Mallory-Weiss tear) accounts for 3% to 15% of people with upper gastrointestinal (GI) bleed 1.

The bleeding is usually self-limited, ceasing spontaneously in 80% to 90% of patients 1. The pathogenesis is not completely understood. However, most patients report an Mallory Weiss syndrome (Mallory-Weiss tear) after an event that provokes a sudden rise in the pressure gradient across the gastroesophageal junction, such as retching, vomiting, coughing, or straining. Retching is also called dry vomiting—trying to vomit but having nothing come out of your mouth.

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.
