Gastric ulcers
Gastric ulcers

Describes the presence of wounds or lesions in the surface of the esophagus, stomach, or duodenum (initial segment of the small intestine) that present themselves with intense pain or burning sensation in the stomach, which generally decreases after eating. Because these ulcers can be a precursor to a cancerous tumor, it is necessary to undergo an upper GI endoscopy to evaluate the size and degree of the ulcer or multiple ulcers, taking biopsies or tissue samples for examination under the microscope. Ulcers can be resolved with medical treatment.
