Gastric edema is not particularly serious and can be improved by medication. There is an abnormal gastric mucosa on the surface of the stomach, which is capable of secreting digestive juices and also has a protective effect on the stomach wall. Gastric edema is the most common symptom of gastritis, which is relatively superficial and therefore causes less impact. For people with the phenomenon of gastric edema, they can be treated with appropriate medications. Some people with gastric edema are associated with excessive secretion of gastric acid, so they need to use drugs that inhibit gastric acid, such as omeprazole and lansoprazole. At the same time, drugs that protect the gastric mucosa should be used, such as colloidal bismuth, aluminum thioglycollate and other drugs to promote the repair of the gastric mucosa. In some people, recurrent gastric edema is caused by H. pylori infection, so antibiotic drugs should also be used to kill H. pylori, and try to choose a combination of two antibiotics.
