The frequent urge to pass gas is associated with irritable bowel syndrome, imbalance of intestinal flora, and excessive intake of gas-producing foods. The manifestations of irritable bowel syndrome are varied, and some people will have slow intestinal peristalsis and impaired intestinal function as the main symptoms. Because the absorption function of the intestine is impaired, it is unable to absorb the gas in the intestinal lumen and expel it from the body, so increased outgassing will occur. When the intestinal flora is balanced, not only the intestinal immunity will be higher, but also the absorption function of the intestine will be normal. Once there is an imbalance of intestinal flora, not only will it affect the absorption and secretion function of the intestine, some people’s intestinal harmful bacteria will also overgrow, especially when the excessive growth of gas-producing bacteria will react with food residues and produce a lot of gas, so there will be increased exhaust. Some foods produce a lot of gas during digestion when they are consumed in large quantities, such as eggs, sweet potatoes, soybeans, etc. Excessive intake of such foods will produce more gas during digestion and lead to excessive gas in the intestines, resulting in increased exhaust.
