Since the discovery of Helicobacter pylori and its role in peptic ulcer disease, two strategies for low-cost treatment of uninvestigated dyspepsia have emerged: "test and treat" and "test and scope." The efficacy of these strategies is examined, with a review of several recent studies. Controversy exists as to the usefulness of eradication of H. pylori in the treatment of non-ulcer dyspepsia. Results of four large trials are presented as an illustration of this controversy. Guidelines for the management of dyspepsia and non-ulcer dyspepsia are reviewed.
