What should I do about chronic gastritis?

Previously, due to work-related factors, my diet and lifestyle were irregular, leading to several clinical symptoms of chronic gastritis—such as recurrent epigastric pain and diarrhea—which are likely attributable to chronic gastritis. Therefore, if such symptoms occur, it is strongly recommended—under the guidance of a gastroenterologist—to initiate treatment with medications that protect the gastric mucosa and suppress gastric acid secretion. Additionally, maintaining regular dietary habits is essential, and a carbon-14 urea breath test should be performed for further evaluation.
