The links between H pylori and nonulcer dyspepsia are debated; however, some patients with nonulcer dyspepsia benefit from eradication. Indeed, H pylori eradication is the first-line and preferred treatment for H pylori -infected dyspeptic individuals. [1] Patients with symptoms have a higher eradication rate than patients with nonulcer dyspepsia disease. Eradication of H pylori in patients without peptic ulcer disease has resolved the dyspepsia in a few cases. If successful H pylori eradication does not resolve dyspeptic symptoms, patients should be considered to have "functional dyspepsia."
