Frequent flatulence is caused by imbalance of intestinal flora, indigestion, irritable bowel syndrome and gynecological diseases. First of all, the balance of intestinal flora is not only conducive to the absorption of nutrients in food, but also promotes the elimination of feces. Once there is an imbalance of intestinal flora, the bad flora will react with food residues to produce gas, thus leading to small stomach bloating. Secondly, in the event of indigestion, the food residue in the intestine contains a large amount of undigested food, and this type of food ferments badly in the intestine, causing a feeling of flatulence. Then some people have irritable bowel syndrome, in the attack of the disease, the intestinal tract function is damaged, can not absorb the gas in the intestinal cavity, so there will be a bloated stomach. Finally, women often have flatulence related to gynecological diseases, such as pelvic inflammatory disease and adnexitis, which need to be treated for gynecological diseases to be improved.
