You can drink more water when you have too much stomach acid. Although water does not neutralize and reduce the effect of stomach acid, it can dilute the stomach acid, which will also reduce the damage to the gastric mucosa after dilution. However, it should be noted that the secretion of stomach acid is likely to induce gastritis, gastric ulcer and duodenal ulcer and other diseases, and drinking more water has no significant therapeutic effect on these diseases. If you have symptoms of high gastric acid secretion such as acid flooding and burning pain in the stomach, you should consider doing medication in time. H2 receptor blockers such as metformin and famotidine and proton pump antagonists such as omeprazole and lansoprazole have significant effects on reducing gastric acid secretion. If gastroscopy has suggested the formation of gastritis or gastric ulcer, it also needs to be treated with gastric mucosal protective agents such as aluminum thioglycollate gel or bismuth pectin, and in the case of combined H. pylori infection, antibiotic treatment such as clarithromycin is added.
