Mallory-Weiss is a medical condition characterized by tears at the gastroesophageal junction, typically caused by forceful vomiting or retching. It involves mucosal lacerations that can lead to painful bleeding. In clinical contexts, the term denotes a specific, identifiable mechanism of upper gastrointestinal hemorrhage, distinct from other tear-related injuries. The eponym reflects physicians Mallory and Weiss who first described the syndrome.
