It is suggested to eat digestible foods such as rice porridge, millet porridge, lean meat porridge, hot milk, lotus root starch, noodles, bread, eggs, yam, papaya, pumpkin, steamed fish and so on. If patients with chronic gastritis have no clinical symptoms, they don't need to pay attention to their diet, and a normal diet and a light diet can do it. For patients with clinical symptoms, it is suggested that medication can be used, such as antacids combined with stomach-protecting drugs or drugs beneficial to digestion. We should pay attention to eating regularly and quantitatively in our daily life, and we must return to a normal diet after the illness recovers, so as to avoid the decline of stomach function.
