See the list below:

  • Although a staging system for the H pylori infection has not been established, several steps in disease progression are well described.

  • The first step is chronic gastritis, which is followed by the second step, atrophic gastritis. The third step is intestinal metaplasia, which may evolve into dysplasia. The last step in this process is gastric adenocarcinoma.

  • This process is very slow (ie, decades) and may stop at any step because gastric cancers probably require several other factors to develop, not only an H pylori infection.
