Belching, feel gas blocking considerations and reflux esophagitis, chronic gastritis and small intestinal obstruction, etc., need to address the cause of drug treatment, if necessary, surgical treatment, and so on. 1. Reflux esophagitis: the typical symptoms are acid reflux, heartburn, and some patients may also show belching, difficulty in swallowing, etc. Acid suppressants (such as omeprazole, etc.) and pro-dynamic agents (such as domperidone, etc.) can be used for treatment. 2. Chronic gastritis: often manifested as discomfort, fullness, hidden pain in the upper and middle abdomen, belching, pharyngeal discomfort and other symptoms can also occur. If it is accompanied by Helicobacter pylori infection, it needs to be eradicated by using quadruple therapy, i.e. one proton pump inhibitor, one bismuth agent and two antibiotics, commonly used are Clarithromycin, Amoxicillin, Bismuth Potassium Citrate, Omeprazole and so on. 3. Small bowel obstruction: it often causes epigastric flatulence, belching, nausea and vomiting, which manifests as belching and feeling of gas blockage, and requires gastrointestinal decompression and drainage, as well as intravenous rehydration to maintain electrolyte and acid-base balance. If no improvement is possible, surgical treatment may be considered. The above medications should be used under the guidance of a medical professional. If the above situation occurs, please consult a doctor in time, clarify the cause of the disease under the guidance of a professional physician, and carry out reasonable and standardized treatment.
