Etiological factors of duodenal and gastric ulcers

Abstract

The most common cause of duodenal and gastric ulcer was Helicobacter pylori, and it was responsible for three-fourths of the cases. About half of the patients had a history of nonsteroidal antiinflammatory drug use, and nonsteroidal antiinflammatory drug and Helicobacter pylori were both responsible for the ulcer in three-fourths of these patients. In about one-tenth of the patients, nonsteroidal antiinflammatory drug use was the cause of ulcer alone, and about one-tenth of the ulcers were classified as idiopathic.
