Belching after eating is not necessarily a disease. Belching is a loud sound made by the gas in the stomach going up to the throat to be discharged after eating. If you eat flatulence food such as sweet potatoes, buckwheat, glutinous rice, carbonated beverages with gas, or eat very quickly, can lead to eating belching. Overeating can also cause food to remain in the stomach for a longer period of time, leading to fermentation and belching and other discomforts. Digestive diseases such as reflux esophagitis, peptic ulcer, etc. will have acid reflux, belching, stomach bloating and other symptoms. Therefore, belching with meals is not necessarily a disease. In order to rule out GI diseases with symptoms of belching with meals, gastroscopy, C13 breath test, ultrasound, etc. can be done to assist in the diagnosis. Patients with eating belching can adjust their diet to avoid cold, irritating and indigestible foods and avoid overeating. Patients with functional dyspepsia have poor gastrointestinal function dynamics, it is recommended to add drugs to promote gastrointestinal peristalsis, such as mosapride for symptomatic management. Gastroesophageal reflux disease can be given to inhibit gastric acid to protect the gastric mucosa of drugs. Patients with peptic ulcer are mostly infected with Helicobacter pylori, and anti-Helicobacter pylori treatment, such as omeprazole, bismuth potassium citrate, amoxicillin, and clarithromycin, is often needed. Patients who eat belching are advised to consult a physician to clarify the cause of the disease and use medication under medical supervision.
