Mild intestinal metaplasia is recommended to be reviewed by gastroscopy once every one or two years. Since intestinal metaplasia is a precancerous lesion of gastric cancer, and there is no enough clinical research evidence to show that there are drugs that can completely reverse intestinal metaplasia, so the only way is to check gastroscopy regularly to observe the severity of intestinal epithelial metaplasia of the gastric mucosa, and also to see if there is any intraepithelial neoplasia of the gastric mucosa through pathological examination. Helicobacter pylori infection can also lead to intestinal metaplasia, so it is also necessary to carry out Helicobacter pylori examination, and if the Helicobacter pylori is positive, it is also necessary to carry out bactericidal treatment. Patients should eat a light diet and reduce the stimulation of high salt and spicy food to avoid damage to the gastric mucosa. If stomach discomfort occurs during the interval between two retests, please go to the hospital immediately.
