The time to review gastroscopy for atrophic gastritis needs to be analyzed with specific circumstances. If it is accompanied by intestinal epithelial hyperplasia, it is recommended to review gastroscopy in about 1 year; if it is accompanied by atypical hyperplasia, review gastroscopy in 6 months to 1 year; if it is accompanied by mild heterogeneous hyperplasia, review gastroscopy in 2-3 months; if it is accompanied by severe heterogeneous hyperplasia or high grade intraepithelial neoplasia, it needs to be treated with endoscopic minimally invasive surgery in time. Atrophic gastritis with intestinal degeneration has the potential for cancer and requires regular gastroscopy to monitor the degree of progression. If the condition improves or if there is no significant change in the review, the gastroscopy can be reviewed for a longer period of time. If the condition worsens and the pain pattern changes, the gastroscopy needs to be checked in time to diagnose whether the condition has changed and to provide timely symptomatic treatment. Chronic atrophic gastritis is prone to recurrent attacks and periodic pain. It is recommended to combine dietary control and medication, to eat a light and easily digestible diet, to avoid spicy and stimulating, greasy food, and to develop good habits.
