The patient with gastritis has stomach pain after eating, which may be caused by the patient eating too much, or eating something that is irritating to the gastric mucosa. If the patient has stomach pain, it is recommended to take proton pump inhibitor, omeprazole, rabeprazole or lansoprazole orally for symptomatic treatment. If the stomach pain is serious, you can take atropine and probenxin orally to relieve the symptoms of pain. Patients with gastritis must pay attention to not eating too much, just six or seven times full, and also avoid eating raw, cold, spicy and irritating food, because these foods will stimulate the gastric mucosa, which is not conducive to the recovery of the disease, and will also lead to the aggravation of the disease, The diet of patients with gastritis should be light, low salt, low fat and low greasy food.
