Chronic irregular stools often indicate abnormalities in the body. Common causes include organic pathologies such as intestinal cancer, intestinal tuberculosis, inflammatory bowel disease, and functional pathologies such as intestinal dysbiosis and intestinal dysfunction. If the stool is not formed for a long period of time, patients are usually advised to consult a gastroenterologist. If the cause is intestinal cancer, surgery is the main treatment, together with chemotherapy and radiotherapy. In case of intestinal tuberculosis, the patient may have mucopurulent stools, etc. Anti-tuberculosis treatment should be given early, in sufficient quantity and duration, and glucocorticoid treatment should be given if necessary. If it is caused by enteritis, its treatment is mainly based on anti-inflammatory and immunosuppressive drugs. In addition, patients are advised to develop good habits, relax, relieve stress, and reduce the intake of alcohol, nicotine and caffeine to avoid stimulating the digestive system.
