Introduction: Helicobacter pylori infection affects gastric acid secretion. The antral inflammation is generally associated with gastric acid hypersecretion. When the gastric body is affected, acid secretion is attenuated. We examined the effects of the eradication of the H. pylori on gastric acid secretion. Methods: We studied 66 gastric patients with chronic gastritis induced by H. Pylori. Patients were histologically classified through biopsy findings and the study of gastric acid secretion before and 16 weeks after the eradication. The severity of gastric atrophy indicated total achlorhydria. Results: acid secretion returned to normal levels in both, patients with hypersecretion and with hyposecretion in a significant manner. Nevertheless, in severe gastric atrophy there was no recovery in the time elapsed during the investigation. Conclusion: gastric acid secretion tends to return to normal levels after H.Pylori eradication, although the precise mechanisms involved are not yet clear. In case secretion does not happen, time required is longer than 4 months.
