There is no absolute conclusion as to how long atrophic gastritis can live, depending on a number of factors such as the degree of progression of the disease and whether it is complicated by cancer at a later stage. Atrophic gastritis has a certain tendency to become cancerous, and in general, the probability of atrophic gastritis becoming cancerous is 0.5%-1% per year. Therefore, patients with atrophic gastritis must have regular review of gastroscopy. The frequency of review of gastroscopy is decided according to whether the intestinal epithelial hyperplasia is mild, moderate, or severe atypical hyperplasia based on gastroscopy and pathological examination. In the case of severe atypical hyperplasia, surgery may be recommended; in other cases, regular review of gastroscopy and pathology is recommended, and some patients may need to be reviewed once every six months to a year, or at least once every 1-2 years. If chronic atrophic gastritis is not cancerous and there are no serious diseases of the stomach, such as gastrointestinal bleeding, most are able to survive for a long time. Patients with chronic atrophic gastritis, there is no need to worry too much, do a good review, under the guidance of the doctor, regular medication, pay attention to diet, most of the prognosis is good, is a chronic disease, can be carried for a long time, does not necessarily directly affect the life of the patient.
