The condition of loud farting is not a clinical manifestation caused by disease. Generally, if the amount of farting is more, it may be the case that the intestinal spasm caused by the hyperactive intestinal sound due to the faster peristaltic movement is more common. If the volume of gas is relatively loud, it may be due to more gas production, eating foods containing soy products, containing more gas production, or gastrointestinal dysfunction caused by rapid intestinal peristalsis. The most typical clinical condition is irritable bowel syndrome, which can exhibit similar symptoms. However, such manifestations can be accompanied by symptoms of abdominal pain, bloating, constipation or diarrhea, or unformed stools. So simple symptoms can generally be considered to continue observation, while paying more attention to dietary habits, pay attention to the combination of work and rest, exercise, and improve physical fitness. If the symptoms occur repeatedly with abdominal pain or diarrhea, a routine stool examination should be completed.
