Irritable bowel syndrome primarily manifests symptoms such as abdominal pain, diarrhea, and bowel sounds. A colonoscopy examination will not reveal any mucosal changes in the intestines, as it is only a functional disorder with no organic alterations. Taking probiotics orally to adjust the gut microbiome can help alleviate these symptoms. Additionally, traditional Chinese medicine has unique therapeutic effects. Oral administration of Chinese herbal medicine based on TCM syndrome differentiation can also be effective. Furthermore, external TCM treatments such as moxibustion, herbal enemas, and herbal hydrotherapy can also yield good results in treating this condition.
