Patients with epigastric flatulence, abdominal bulging and hiccups should first rule out gastric and intestinal obstruction, which needs to be clarified by taking a standing plain film of the abdomen in the hospital. If there is a clear obstruction in the standing plain film of the abdomen, it is often manifested by the cessation of gas and bowel movement, and this situation requires early surgical treatment. After excluding this situation, it is likely to be gastrointestinal dysfunction, which is seen in functional gastrointestinal disease or hypokalemia, the former needs to be regulated with drugs such as trimebutine maleate, mosapride plus rectum sheng. If gastrointestinal dysfunction is ruled out, blood sampling and ion biochemistry examination are needed to determine whether there is low potassium, and if there is low potassium, infusion of K+ supplementation is needed in time to improve the function of gastrointestinal motility.
