Understanding Vascular ectasia of gastric antrum

Vascular ectasia of the gastric antrum, also called watermelon stomach, is a condition in which the lining of the stomach bleeds.

On an endoscopy (a camera exam of the stomach), the lining looks striped like a watermelon. It is often found in people who also have long-term conditions such as cirrhosis (scarring of the liver), autoimmune disease, systemic sclerosis, or CREST syndrome.

Signs & symptoms

GARD lists these signs and symptoms:

  • Blood in the stool
  • Vomiting blood (hematemesis)
  • Low red blood cells (anemia)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
