A Mallory-Weiss tear is a type of laceration that occurs in the mucosa of the upper gastrointestinal (GI) tract, typically in the esophagus or the gastric cardia.
It is caused by forceful retching or vomiting and is often associated with alcohol abuse or other causes of gastric irritation. The tear can lead to upper GI bleeding, which can range from mild to severe, depending on the size and location of the tear. Treatment for a Mallory-Weiss tear typically involves controlling the bleeding, either with endoscopic techniques or, in severe cases, surgical intervention.
