Long-term farting may be gastrointestinal dysfunction, constipation, inflammatory bowel disease and other diseases. 1. Gastrointestinal dysfunction: due to abnormal intestinal brain interaction, the function of gastrointestinal activity is impaired, and food cannot be fully digested in the gastrointestinal tract, thus generating a large amount of gas, which can cause long-term farting. 2. Constipation: feces move too slowly in the intestinal tract and stay for a longer time, which tends to produce more gas under the action of intestinal bacteria, so it will cause long-term farting. 3. Inflammatory bowel disease: abnormal intestinal immune response, dysbiosis, resulting in intestinal mucosal swelling, congestion, inflammatory changes, farting will occur. If there is a fishy-smelling fart, it is a hint that there may be inflammatory lesions in the intestinal tract. If you find that farting is more frequent, you should go to the hospital in time to avoid delaying your condition.
