Inflammatory diseases of the gastrointestinal tract, such as intestinal mucositis, segmental ileitis, and Helicobacter pylori infection, are the main causes of irregular bowel movements and excessive flatulence. Because the patient’s gastrointestinal tract inflammatory lesions, will lead to the emergence of functional dysfunction and the imbalance of the proportion of bacterial flora phenomenon. After food enters the digestive tract, not only can it not be decomposed and absorbed normally, but it will also have excessive metabolic reactions with harmful bacteria, generating a large amount of gaseous substances. Gas and nutrients will enter the lower digestive tract with the peristaltic action of the stomach and intestines, thus causing patients to have frequent bowel movements, increased gas, diarrhea, watery stools and other symptoms. However, the possibility of non-inflammatory digestive diseases such as irritable bowel syndrome, intestinal flora dysbiosis, and small bowel absorption disorder cannot be ruled out.
