Gastritis is not known to cause constipation. However, some studies linked the eradication of H. pylori (a stomach bug that causes gastritis) to the relief of constipation. Other possible causes of constipation with gastritis are associated constipation disorders, decreased food intake, faulty diet habits, psychological stress, and some medications.
