For gastritis and nausea, it is appropriate to use antispasmodic, antiemetic, and stomach mucosa protective medications. If there is significant vomiting, it can cause loss of body fluids, and it is necessary to promptly replenish fluids. During treatment, attention should be paid to a light diet, mainly consisting of soft, easily digestible food. Try to avoid raw, cold, spicy, and irritating foods. Regular eating habits should be maintained, with meals scheduled and portioned timely, following the principle of eating small, frequent meals. Gastrointestinal diseases are greatly related to emotions; maintaining a good mood has a positive effect on the treatment of gastritis.
