[Gastric ulcer and Helicobacter pylori infection].

Helicobacter pylori infection and the use of non-steroidal anti-inflammatory drugs (NSAID) are considered to be the two major risk factors implicated in the development of gastric ulcer. Helicobacter pylori infection related chronic gastritis is known to be the underlying condition which may lead to gastric ulcer. Development of gastric ulcer as the consequence of underlying chronic gastritis is caused by many factors. Treating Helicobacter pylori infection entails the healing of gastric ulcer, it concomitantly prevents recurrences and complications of gastric ulcer, primarily bleeding, and changes the natural course of gastric ulcer disease. Continuation of antisecretory maintenance treatment beyond ulcus healing and eradication of Helicobacter pylori infection is only indicated in risk groups. Patients with gastric ulcer caused by NSAID use are managed with antisecretory therapy.
