Patients with gastric ulcers should not smoke, as the tar and nicotine in tobacco can damage the gastric mucosa and worsen ulcer symptoms. Patients should pay attention to proper rest, reduce mental stress, avoid excessive tension and irritability, develop regular living habits, eat meals at fixed times and in fixed amounts, eat more vegetables and fruits, eat less spicy and greasy food, and avoid smoking and drinking alcohol. It's also important to consume less strong tea and coffee. Actively use medications for treatment, commonly including drugs that inhibit gastric acid secretion and drugs that protect the gastric mucosa. If there is Helicobacter pylori infection, it is necessary to eradicate Helicobacter pylori. (Medications should be used under the guidance of a doctor.)
