Abdominal bloating but not able to pass gas may be caused by intestinal flora dysbiosis, indigestion, excessive intake of gas-producing food, intestinal obstruction and other reasons.
1. Intestinal flora imbalance: if the gastrointestinal flora imbalance, gas-producing bacteria increase, resulting in excessive gas production, and the anal muscles are tightened, so it is difficult to exhaust abdominal bloating.
2. Indigestion: Indigestion causes slowing down of gastrointestinal peristalsis, leading to accumulation of food in the gastrointestinal tract, which can produce a lot of gas through decomposition and fermentation, thus restricting the evacuation.
3. Excessive intake of gas-producing food: such as eating too much soy products, dairy products, potatoes and other gas-producing food, causing the gastrointestinal tract to accumulate too much gas is not easy to expel.
4. Intestinal obstruction: such as constipation or gastrointestinal tract tumors cause intestinal obstruction, will also be abdominal distension and gas discharge.
Abdominal distension but not discharged gas may also be other reasons, it is recommended to regular hospitals, listen to the guidance of professional physicians active diagnosis and treatment.
