Abstract | BACKGROUND: METHODS: RESULTS: The mean breath N2O concentrations were higher in the following order at all times: partial gastrectomy> atrophic gastritis>normal>young. The maximum N2O concentrations in the patients with partial gastrectomy and atrophic gastritis were 1655 +/- 296 and 1350 +/- 200 (mean +/- S.E.) ppb, respectively, which were higher than that of the normal subjects, 827 +/- 91 ppb (P < 0.05). The maximum N2O concentration in young people was 527 +/- 86 ppb, which was lower than that of the normal older people (P < 0.051). CONCLUSION: These higher N2O concentrations in gastric patients reflect bacterial growth in the stomach due to the reduction of gastric acid.
