Summary

Mallory-Weiss syndrome, also known as gastroesophageal laceration syndrome, refers to longitudinal laceration(s) in the mucosa at the junction of the stomach and esophagus. This can lead to bleeding especially following forceful vomiting.

Mallory-Weiss syndrome is commonly seen in people with alcoholism or bulimia, but it can also be found in other conditions associated with forceful vomiting's such as food poisoning. People with Mallory-Weiss Syndrome can present with painful hematemesis.
