There are three possibilities to consider for bloating: first, excessive gas production in the intestine, second, decreased gastrointestinal motility, and third, incomplete intestinal obstruction. What are the reasons for excessive gas production in the intestine? 1, the reason for the diet: swallowing when eating, habitual swallowing too much, often swallowing saliva, intake of more air, etc. will cause excessive gas production in the intestine. Eating too much gas-producing food. Including asparagus, onions, leeks, garlic, beans, peas, cabbage, celery, sweet corn and other vegetables; apples, mangoes, watermelon, nectarines, plums, pears and other fruits; milk, yogurt, cream, ice cream and other dairy products; drinking too much carbonated beverages, will appear the phenomenon of abdominal flatulence. 2, intestinal flora dysbiosis: under normal circumstances, the intestinal flora according to a certain proportion of the combination of bacteria, the bacteria between the mutual constraints, interdependence, in quality and quantity to form an ecological balance, if the long-term application of broad-spectrum antibiotics, dietary fiber intake in food is too little, sensitive intestinal bacteria are inhibited, uninhibited bacteria and take the opportunity to multiply, thus causing dysbiosis, gas-producing bacteria dominant, there will be excessive gas production in the intestine Phenomenon. And again, the reasons for the weakening of gastrointestinal power? 1, mental and psychological factors: when a person is in a bad mood gastrointestinal motility will be weakened, if the usual workload, increased economic burden, fierce competition at work, the pace of life is too fast, laid off and unemployed, the death of relatives, the stimulation of accidents, interpersonal tension and family disputes, etc. will make people’s gastrointestinal disorders, indigestion, which leads to the occurrence of abdominal distension. 2, functional gastrointestinal disease: functional gastrointestinal disease is the most common disease of the digestive system. This type of disease is also known as functional digestive disorders, functional gastrointestinal disorders, gastrointestinal power disorders and gastrointestinal neurological disorders, such as functional dyspepsia and irritable bowel syndrome are common. The core pathogenesis of these disorders is the disturbance of gastrointestinal motility and hypersensitivity of the gastrointestinal tract to the sensory response to adverse stimuli. Therefore, they are also known as gastrointestinal motility disorders. Due to the lack of gastrointestinal motility, intestinal flatulence is often observed. Finally, what about incomplete intestinal obstruction? In incomplete intestinal obstruction, bloating and abdominal pain occur when the contents of the intestine do not function properly or have difficulty passing. Common extra-intestinal causes of incomplete intestinal obstruction include intestinal adhesions, intestinal torsion, extra-intestinal tumor or abdominal mass compression, and incarcerated external or internal hernia. The intestinal tract itself causes of incomplete intestinal obstruction include inflammation, tumor, stenosis due to other factors such as intestinal anastomosis, polyps or other lesions in the intestinal tract, after major abdominal surgery, peritonitis, abdominal trauma, hypokalemia, etc. What should I do if I have flatulence? 1. Clarify the cause of flatulence. Relevant examinations such as gastroscopy, gastrointestinal imaging and laboratory tests can be performed to exclude organic diseases such as intestinal obstruction or incomplete intestinal obstruction, and relevant treatments can be carried out according to the diseases. 2, control the diet, reduce the intake of gas-producing food. 3.Appropriate aerobic exercise can help the recovery of gastrointestinal tract function and promote defecation. 4.Appropriate application of drugs. The anti-flatulence tablet dimethicone oil can quickly eliminate flatulence and bloating, probiotics can also improve the symptoms of bloating and flatulence, and patients with severe flatulence can be treated with drugs that promote gastrointestinal motility, such as Mosapride and Itopride.
