Helicobacter pylori erosive gastritis generally has a good prognosis through treatment, but the occurrence of intestinal epithelial hyperplasia is irreversible, and a very small number of patients may develop into gastric cancer. Helicobacter pylori erosive gastritis is a kind of chronic gastritis, which is mainly caused by Helicobacter pylori infection causing gastric mucosal erosion, usually leading to gastric mucosal bleeding. Patients often manifest symptoms such as abdominal pain and bloating or upper gastrointestinal bleeding. Clinically, quadruple therapy is often given for treatment, i.e., PPI + bismuth + 2 antibiotic combinations, such as omeprazole, bismuth pectin, amoxicillin, and clarithromycin. Usually the prognosis of this disease is good after systematic treatment, but due to the repeated destruction of intestinal mucosa, it may cause intestinal epithelial hyperplasia, in which case a very small number of patients may further develop into gastric cancer. Once you suffer from this disease, you must go to the hospital and get appropriate treatment under the guidance of the doctor.
