Epigastric flatulence may be caused by improper diet, gastrointestinal dysfunction, peptic ulcer, acute cholecystitis and other diseases, but it is necessary to further define the disease according to specific clinical symptoms and laboratory tests. 1. Improper diet: patients eat too much gas-producing food or cold food, resulting in bloating, nausea, vomiting and other symptoms. 2. Gastrointestinal dysfunction: caused by gastrointestinal infections, intestinal flora imbalance, etc., manifested as postprandial fullness, abdominal discomfort and other symptoms. It is recommended to carry out blood routine, meal barium enema imaging and other tests for further diagnosis. 3. Peptic ulcer: often caused by Helicobacter pylori infection, non-steroidal anti-inflammatory drugs, abdominal bloating, abdominal pain, nausea, nausea (poor appetite) and other symptoms. H. pylori test and X-ray meal barium examination are recommended for further diagnosis. 4. Acute cholecystitis: often caused by obstruction of the gallbladder duct and bacterial infection, manifested by symptoms such as right upper abdominal pain, abdominal distension, anorexia, and eructation (hiccups). Laboratory tests such as ultrasound, MRI and CT are recommended for further diagnosis. Epigastric flatulence may also have other etiological causes, such as gastrointestinal tumors, cirrhosis, etc. It is recommended that patients whose symptoms have not been relieved for a long time go to the hospital in time to avoid delay.
