Chronic superficial atrophic gastritis is a chronic digestive disease characterized by atrophy of the epithelium and glands of the gastric mucosa, reduction in number, thinning of the gastric mucosa, thickening of the mucosal base with pyloric glandular hyperplasia and intestinal glandular hyperplasia or atypical hyperplasia, and is a multipathogenic disease and precancerous disease. The disease is mainly caused by H. pylori infection, poor dietary habits such as smoking and alcohol consumption, or reflux of bile or duodenal fluid, poor physical condition, genetic factors, exposure to metals such as lead and mercury, and radiation therapy for ulcer disease. Most patients do not have obvious manifestations, and some patients only show discomfort in the upper and middle abdomen, such as dull pain, fullness, and burning sensation. They may also have indigestion symptoms, such as loss of appetite, acid reflux, nausea, and hiccups. Patients who experience significant discomfort should promptly visit a hospital gastroenterology department. The diagnosis should be confirmed by gastroscopy, pathology and laboratory findings under the guidance of a physician. The diagnosis is usually confirmed by gastroscopic findings of redness, adherent mucus and enhanced reflection. Patients should avoid drugs that damage the gastric mucosa. If H. pylori infection is the cause, anti-H. pylori treatment is required, usually in the form of quadruple therapy. Drugs such as aluminum thioglycollate can also be applied under medical supervision, as well as drugs to regulate and restore gastrointestinal motility. In addition, people suffering from chronic superficial atrophic gastritis in daily life should pay attention to a regular diet, eat less and more meals, and eat a light, easily digestible diet, such as millet porridge and noodles. Avoid intake of cold, spicy and other irritating foods, high salt, pickled and baked, smoked foods, smoking cessation, alcohol avoidance, keeping a happy mood, avoiding late nights and excessive exertion, and regular re-examination.
