Gastric ulcer
A hole in the lining of the stomach corroded by the acidic digestive juices which are secreted by the stomach cells. Ulcer formation is related to H. pyloridus bacteria in the stomach, anti-inflammatory medications, and smoking cigarettes. Ulcer pain may not correlate with the presence or severity of ulceration. Diagnosis is made with barium x-ray or with the use of a viewing tube slipped through the throat to the stomach (endoscopy).

gastric ulcer n a peptic ulcer situated in the stomach

* * *

an ulcer in the stomach, caused by the action of acid, pepsin, and bile on the stomach lining (mucosa). The output of stomach acid is not usually increased. Taking NSAID (nonsteroidal anti-inflammatory drugs) or corticosteroid are predisposing factors. Helicobacter is often present. Symptoms include vomiting and pain in the upper abdomen soon after eating, and such complications as bleeding (see also haematemesis), perforation, and obstruction due to scarring may occur. Symptoms are relieved by antacid medicines, but most ulcers heal if treated by an antisecretory drug. Surgery may be required if the ulcer fails to heal. Since stomach cancer may mimic a gastric ulcer, all gastric ulcers should be examined by a gastroscope to aid in their differentiation.
