Understanding the Syndrome
Mallory-Weiss Syndrome is characterized by tears in the mucosa of the esophagus and stomach. These tears are most commonly caused by forceful vomiting or retching. The condition can lead to bleeding, which might manifest as vomiting blood.
Risk Factors You Should Know
Alcohol use is a significant risk factor for Mallory-Weiss Syndrome, with up to 80% of patients having a history of heavy drinking. Other risk factors include having a hiatal hernia, though recent studies suggest this might not be as significant. Surprisingly, age isnβt a major factor, as most cases occur in people under 40.

Symptoms and Diagnosis
Symptoms typically include vomiting blood and abdominal pain. Diagnosis is often confirmed with an endoscopy, a procedure that allows doctors to see inside the esophagus and stomach. This test helps rule out other causes of bleeding, such as ulcers.
