Belching may be related to physiologic or pathologic factors, such as chronic gastritis and reflux esophagitis. Physiological factors generally do not require special treatment, but some pathological factors are more difficult to cure. Chronic gastritis can generally be cured clinically with medication or surgery, while reflux esophagitis can be cured with medication or surgery. 1. Physiological factors: belching occurs when a large amount of air is swallowed during frequent salivation in times of stress. Drinking too much carbonated beverages can also cause belching, which can be relieved on its own without special treatment. 2. Pathologic factors: (1) Chronic gastritis: it is caused by Helicobacter pylori infection and other different causes of chronic inflammation of the gastric mucosa, causing stomach discomfort, belching and other symptoms. Lansoprazole, clarithromycin, metronidazole, bismuth pectin can be considered to kill germs, and at the same time can be combined with mosapride, aluminum thioglycollate, etc. to promote gastric emptying and protect gastric mucosa. (2) Reflux esophagitis: due to esophageal dysfunction, gastric contents reflux into the esophagus, causing belching, vomiting and other symptoms. Consider omeprazole and ranitidine to inhibit gastric acid, and combine with domperidone to promote gastric emptying and improve the symptoms of belching. Laparoscopic fundoplication can be considered for patients with insufficient drug acid suppression or pathologic acid reflux. The above drugs are for reference only and should be used in accordance with medical advice. When belching occurs, it is recommended to consult a doctor for further examination, to clarify the cause with the help of the doctor, and to carry out targeted treatment or therapy.
