Patients with reflux esophagitis must avoid raw, cold, spicy, and irritating foods, including tobacco, strong tea, and coffee. Nicotine, primarily found in cigarettes, adversely affects the patient's blood vessels and irritates the stomach and esophageal mucosa to varying degrees. It also stimulates the trachea, causing coughing. Therefore, it is crucial for patients with reflux esophagitis to quit smoking. Moreover, these patients must strictly control their diet, avoiding overly spicy, acidic, hot, or overly cold foods. Treatment is important, but regular maintenance is also very crucial.
