Frequent flatulence in people has been linked to irritable bowel syndrome, indigestion, and frequent consumption of gas-producing foods. Irritable bowel syndrome leads to dysfunction of the intestinal tract, which is unable to absorb the gas from the intestinal lumen, so that large amounts of gas are expelled through the anus. The body is unable to break down and digest food properly when it is indigestible, and the food waste contains large amounts of unabsorbed material, as well as causing an overgrowth of bacteria in the intestinal system. The reaction between the bacteria and the unabsorbed food residue produces a large amount of gas, leading to excessive gas buildup in the intestinal lumen, resulting in the symptom of flatulence. Some people usually like to eat protein, starchy foods such as soybeans, sweet potatoes, etc., these foods in the process of digestion will produce a lot of gas, the gas gathered too much will be excreted through the anus, thus resulting in an increase in the number of exhaust.
